It’s been a hot minute since I wrote about my nemesis, the cervid antler. But no worries. Because if there’s one thing you can count on, it’s that new research will always be published about antlers.
The most impressive thing about antlers is their regenerative ability. Coupled with their extremely rapid growth rate, antlers are a natural wonder of the world. Cells in the pedicle are special in that if you move them around, they still grow an antler. Leg antler anyone? Pedicle periosteum is responsible for this marvel. They know their job and they are good at it. Stories of unicorn or 3-antlered bucks are likely the result of some sort of trauma that shifted those cells around and – voilà, a new antler!
Pedicle periosteal cells express embryonic stem cell markers and can differentiate into multiple cell types. The periosteum (membrane of blood vessels and nerves that wraps around most bones giving them their blood supply and sense of feeling) has limited potential to proliferate, which makes regeneration of a limb impossible.
But before you start worshipping at the altar of the pedicle periosteum, there’s more! My handy dandy google alert delivered this gem to my inbox last week. This antler research falls into the “love” category of my love/hate antler relationship. Turns out it’s not just those fancy cells that can regenerate. They have an Avenger team.
If I do a quick body scan, I can tell you a story for every scar I find. The crescent shaped scar on my knee – I lost my balance in the boat while checking wood duck boxes; the V on my right hand – Sherman, the German Shepherd; the line on my left hand – me vs the hot oven rack. Scars are a part of life, right?
Scars are part of healing but there is a difference between scarring and regeneration. Scarring is a form of fibrous tissue which closes a wound but doesn’t restore the original tissue structure or function. Deer lose their antlers every year. The result is an open wound on their head. Yet when the wound closes, skin regenerates. No scars!
The Hulk that is the pedicle periosteum doesn’t go it alone. It takes a team to save the world or in this case an antler. Components in a deer’s blood during the antler regeneration period cause generic regenerative wound healing. Here’s what that means. Researchers found that foreheads wounds (inflicted as part of the study) during the spring and summer exhibited regenerative healing while those wounds healed with a scar in the fall and winter.
When antlers are growing, deer are like Captain America with superhuman healing ability. But this elixir isn’t just for deer. Topical application of deer blood plasma from the antler regeneration period applied to skin wounds in rats also promoted regenerative healing with increased cell proliferation, impaired inflammatory response, reduced myofibroblast transformation and elevated collagen remodeling. The blood was analyzed and fun things like IGF1 and PRG4 were found. I’m not venturing into that world, but you should read the paper for the details. It is pretty cool.
The conclusion: deer blood during the antler regeneration period contains magical healing properties capable of inducing regenerative wound healing which is not limited to deer!
Could deer bridge the gap between us and Captain America? Maybe.

Candy Conformations
What’s your favorite candy? M&M’s, Reese’s peanut butter cups, Hershey’s Kiss, Twix, Kit Kat? For me, it’s Kit Kats.
According to Hersheyland, Kit Kats landed in the US from the UK in 1935. Today, more than 15 million a DAY are made in the Hazelton, PA factory. That sounds a bit like heaven.
For 40 years of my life when I reached for a Kit Kat, I knew exactly what I was getting – layered crispy wafers wrapped in chocolate. Straight out of the freezer or fridge is best! Then something happened. All of a sudden, a Kit Kat wasn’t just a Kit Kat. In 1996, Kit Kat Orange was introduced in the UK, and it was a glimpse of things to come.
You can thank the low carb craze of the early 2000s for the mutation of Kit Kat into multiple variants as Hershey and other confectioners tried to stop the downward spiral of sales. Now when you grab a Kit Kat at check out, you better read the package. It could be mint or caramel or dark or churro or ghost toast or birthday cake or perhaps the worst mutation pink lemonade – Yuck!
Why mess with an original? Kit Kats were perfect just the way they were. At least, they were to me but these new twists on an original reversed the sales decline.
While far from a confectionary delight, chronic wasting disease (CWD) and Kit Kats do have some commonalties. CWD is a fatal brain disease that affects species like deer and elk. There is no cure or treatment. Deer get it from coming into contact with another infected deer or through contact with contaminated environments because infected deer shed prions which cause the disease.
When chronic wasting disease was the new prion disease on the block in the 1960s, no one was asking what “flavor” it was. The OG CWD if you will. There was only one transmissible fatal prion disease in deer.
Perhaps Mother Nature is a marketer. Expanding and diversifying to keep things fresh. Because right around the same time as the Kit Kat evolution, researchers began to uncover different strains of CWD. Who knew the low carb craze would have such an impact?
CWD is caused by a misfolded protein known as a prion. Like towels, they can be folded in many ways. Every misfold is a different strain of CWD. Right now, there are at least 10 strains of CWD. The end result of all deer infected with any strain of CWD is the same but what happens leading up to that isn’t. CWD strain alters the 18 to 24 month incubation period; the shedding of prions from an infected animal; the distribution of the prions in the body; and, most importantly, the species barrier. Currently, CWD is known to only affect deer species. If CWD were to infect a critter other than deer, it would be a game changer.
What’s driving the emergence of new strains isn’t lagging sales but genotypes. In order to be competitive in the CWD market, you need to diversify – try new folds. See which one is appealing to the target demographic – in this case different deer genotypes. You see there are some genotypes, often referred to as less susceptible or durable genotypes, in deer that aren’t that crazy about OG CWD. Deer with these durable genotypes still die if they are infected, but they live longer. This gives “marketers” the opportunity to try new folds. And they seem to have found a winner in a strain known as H95+. Those durable deer genotypes don’t hold up when exposed to this CWD strain and it could be the one to branch out to other species beyond deer. That would open a whole new market to CWD.
Yes, Mother Nature is definitely a marketer. No one should be surprised by this. Look at how successful she has been – Flu, Covid, the common cold. We might not like all her products, but you have to give it to her and the Kit Kat masterminds. They know how to increase sales and reach.

The Game of Life
It’s mid-May and there are already fawns on the ground. We are working our way up to the peak of fawn drop at the end of the month. We’ve talked a lot about fawn survival on this blog. Of course, most of the discussion revolves around the monstrous predators stealing babies from their forest beds. Yes, the previous sentence is dripping with sarcasm.
Predators are the party driving these interactions. Without them, fawns would live blissful lives without care or worry. This is untrue but decades of bad press are hard to shake. Kind of like female’s “passive” role in reproduction. This also is untrue and if I get Duane to agree, maybe I’ll write a post about that someday.
Does are yet again not given enough credit. Shocking. They play an active role in the survival of their fawn. And I’m just not talking about feeding and changing diapers.
White-tailed deer fawns are hiders. They use the armor of concealment to protect them when mom isn’t actively caring for them. They need protection because they are tasty and bears, coyotes, and bobcats need to eat so they can feed their own babies.
Decisions of where and when to hide are made by fawns but the conditions surrounding these decisions are linked to many things. Predation risk and habitat are 2 big ones. Predation risk is easy – fawns and does want the lowest risk possible to maximize survival.
Habitat can be 2-fold – it offers places to hide and provides does with the nutrition they need to support a growing fawn(s). The faster they grow, the better the chance of survival. If mom needs to range too far from her fawn, she might miss detecting a predator. If she is too close, she might give her fawn’s location away.
That’s the “where” part but the “when” also matters. When a fawn hides and when its active also plays into predation risk.
Who knew hiding could be so complicated!
Several studies were recently published looking at the role of maternal behavior in fawn survival. For neonatal mule deer, hiding was greatest at night, and they were more likely to hide in short vegetation. This last part seems counterintuitive but remember mom needs to see the coyote so she can open up a can of whoop a$$. If the grass is too tall, she can’t see what’s coming.
Hiding at night is a good idea because that’s when predators are most active. During this period, mule deer fawns were more likely to hide and were farther away from mom. In fact, another study on white-tailed deer found that fawn survival decreased as the proportion of nighttime visits by mom increased. Maternal behavior directly influenced fawn survival. Maternal behavior can be altered by various activities. So before you start crucifying coyotes, bears and bobcats, ask yourself if there is anything you are doing to make it difficult for a doe to visit her fawn during the day.
Another way doe behavior can influence fawn survival is through movement. In Delaware where fawns live without predators, younger females move more than older females during lactation. Younger females (<4 years old) had greater postpartum displacements than older females expending more energy to find food or avoid aggressive interactions with more socially dominant females. Fawns of younger females had reduced survival rates compared to older females. Emaciation was the most common cause of fawn mortality even though birth weights were the same for both groups.
Younger females are still growing. Add to this the energetic burdens of lactation and increased movement and there just isn’t time to get enough to eat to support themselves and their fawns.
If you throw people and predators into the mix, a mom has her hands full.
Whether a fawn lives or dies is not based solely on a predator’s ability to find a fawn. There are many players on the field, and no one plays alone.

We interrupt the regularly scheduled program…
Things are greening up and the birds have returned. Nest building and turf wars are in full swing. And in a few short weeks, overwhelming cuteness will appear in spotted packages on wobbly legs. I have been working on a post about maternal behavior and what it means for those new to the deer world. But that is going to have to wait. Because I became distracted by a headline.
I am passionate about several things. Duane and I share a passion for the use of non-toxic ammunition while hunting. I have regularly advocated for the female segment of the deer population and their overlooked value. The other hill I am willing to die on is feeding. More specifically, that no one should feed deer.
I give a lot of presentations on many topics – to hunters, to students, to the general public – and the message I give in every one of them is “You can forget everything from this presentation except that feeding deer is bad and DO NOT do it.”
Ah feeding, how do I hate thee? Let me count the ways. I hate thee to the depth and breath and height My soul can reach…
Yes, I hate feeding or providing any sort of supplement to deer. In short, there is no need for it and it only causes problems – for deer, for people, for habitat, for wildlife.
For deer, the problems are numerous and the biggest is the spread of diseases and conditions like chronic wasting disease, rumen acidosis, and foundering to name a few. Honestly, I could go on and on and on about the harm it causes but I’m trying to keep this brief. If you’d like a list of publications, email the blog and I’ll be happy to send you the MANY links to the research.
There is also the risk of disease beyond deer to other wildlife, people, and pets. Rabies, salmonellosis, toxoplasmosis, P. tenuis, and tapeworms don’t discriminate between raccoons, dogs, goats, or your kids.
And deer feed isn’t just attractive to deer. Raccoons love it. Rodents love it. Foxes love rodents. And bears love deer. That’s right. Brown bears in Poland visited ungulate feed sites 3 times more frequently than would be expected. Ungulate feeding affected the movement patterns of bears! And there are several studies that demonstrate increased ground nest predation at deer feed sites.
Also do you know what happens when you feed a stray cat or dog? The same thing happens with wildlife. They get used to it. They expect it. That can be disastrous. A captive stag killed the guy who was feeding it. But remember deer aren’t the only ones eating. Racoons are one of the highest rabies risks in the U.S. They are a rabies reservoir in the eastern U.S. extending from Canada to Florida and as far west as the Appalachian range. So when I saw this guy, I nearly LOST MY MIND!
I knew exactly what bill this was referencing. It states, “The department may not adopt a rule or implement a policy prohibiting or restricting the use of supplemental feed on private property for hunting a big game animal.”
How is limiting the ability of the stewards to safeguard the wildlife resources of North Dakota a “victory” for hunters?
Wildlife is a public resource. This is what sets North America apart from Europe and the king’s deer. Land ownership is one thing, but wildlife belongs to everyone regardless of deed. The Public Trust Doctrine establishes public ownership of wildlife as law. This is the cornerstone of the North American Model of Wildlife Conservation. To lose sight of this is tragic. Because it sets the stage for the “have’s” and “have nots.” The wants of a few should not come at the expense of the many.
This is not a victory. It’s a blow to everyone. Our wildlife resources are our greatest triumph. Responsible management is the duty of every stewardship agency.
If you can forget everything from this post, remember that FEEDING DEER IS BAD AND DO NOT DO IT.

The Griswolds
I look forward to spring every year. Daffodils, peepers, and promise of summer with some 60 degree days. To that end, 2025 has been a bust. The daffodils and peeper held up their end of the bargain just to be slapped by weeks of cold, rainy, gross weather. I’ve been depressed
But last night an unexpected rise in temperature lifted my spirits on my evening walk and prodded others out of their slumber. I spotted a couple of bats feasting on a recent hatch of insects. YES!! Signs of life! Lots of critters besides bats and bugs check out in the winter only to reemerge during more favorable conditions, including snails.
One of our very first blog posts was about snails and the possible interaction of soil and vegetation and deer. Ten years later, I’m going to talk about snails and deer and…”worms.” Specifically, nematodes. A parasitic bug if you will. Technically, neither worms nor nematodes are bugs. And I’m positive entomologists, helminthologists, and nematologists would be highly insulted, but this is my blog post.
For those keeping count, this is my third “bug” related post in as many weeks. This one was Duane’s idea. Parelaphostrongylus tenuis is a parasitic roundworm that infects many hooved mammals but white-tailed deer are their natural host. Also known as brain worm or meningeal worm, they are affectionately called P. tenuis by those that study them (or students that take courses in which spelling counts).
Bug or not, P. tenuis has a complicated and fascinating life cycle. Several life stages and different host animals are required to complete a full transition from an egg to an adult that lays more eggs.
White-tailed deer ingest larvae, which migrate through the digestive tract via spinal nerves to reach the spinal cord and the brain. There larvae develop into adults, reproduce, and lay eggs within deer. Eggs hatch and travel via the bloodstream to the lungs. Deer get a tickle in their throat, cough up the larvae, swallow them, and they go out the back of the deer into the world.
These new larvae deposited into the world in an M&M-sized poop pellet are actually not infectious. For that, P. tenuis needs a hand or, in this case, a foot. The larvae must penetrate the foot of a snail noshing on those P. tenuis-flavored fecal M&Ms. There they mature to another larval stage. At last, they are ready to infect again!
Deer going about their daily business snack on a snail and get that little extra just like when they vacuum up those plant dwelling insects…and the cycle starts all over again.
What happens to deer infected with P. tenuis? Nothing! P. tenuis lives and breeds in the meninges. As a refresher, meninges are the 3 layers of membranes that protect the brain and spinal cord. Conditions like meningitis, an infection of the meninges caused by bacteria, viruses, fungi, or parasites, are incredibly serious and can cause death if untreated. Yet white-tailed deer walk around like it’s no big deal. Other than that irritating cough to get the larvae through the system, deer don’t even notice or show any sign of disease.
P. tenuis is common almost everywhere white-tailed deer are found in eastern North America. About 80% of deer are infected with little to no disease seen.
That, however, is not the case for other hooved mammals. Moose, mule deer, black-tailed deer, elk, caribou, pronghorns, and big-horned sheep are all susceptible. So are llamas, sheep, goats, and alpacas. Unfortunately for all these critters, the blissful relationship enjoyed by white-tailed deer and P. tenuis is not replicated. If they swallow one of those seeded snails, worms won’t mature into reproductive adults. Instead, they just wander around the brain and spinal cord damaging meninges like some irate drunkard that is refused another round. The result is severe neurological disease and death.

For these critters, living in the same area as white-tailed is dangerous. Every year, some poor Pennsylvania elk snacks on the wrong snail and meets its demise.
In fact, P. tenuis is contributing to moose population declines in areas of North America. It’s like living next door to Clark W. Griswold. Your hapless neighbor is creating a vortex of doom completely oblivious to the destruction they are causing.
And the Griswolds are on the move pooping out larvae for snails to find. White-tailed deer are expanding their range into areas where endangered woodland caribou live. If the wolves that follow the deer don’t get the caribou, the larvae-infected snails might!
Clark Griswold means well. He’s just got a lot of baggage. The same is true for our beloved white-tailed deer.

Greetings from the North!
The Susquehannock Crew has been busy working on FLIR surveys each night. So far, we’ve completed 19 of 21 first round surveys. Some nights we see a lot of deer and other nights hardly any. Along with deer, we see lots of grouse, woodcock, and porcupines, as well as an occasional fox, fisher, and bear.
We’ll continue to work most nights to ensure that we finish our second round of surveys before the crew moves on to their next adventure.

Hello all!
Alas, the season finale of our deer trapping escapades has come! It’s been a bittersweet season to say the least. We’ve labored through the ups and downs that come with trapping and poured literal blood sweat and tears into the outcome. On our last week we managed to wrap it up with a fawn and very nearly got a collar-able deer on the last day, but it just wasn’t meant to be. I was very happy to be lead on our last official deer of the season though- I almost forgot how much fun it was to be in there firsthand!
There was a peculiar final bout of snow last week before we closed our Clover traps for the year. It certainly didn’t linger for very long, but it made for another beautiful day in the field.
Last week we mainly focused on trapping, with just a day or two of FLIRs. We’ll be back on the surveys in full force from now until they’re completed, in addition to moving all our field equipment back into storage. TONS of porcupines on the move as we’ve been searching for deer in the thermals, and before we pulled the cameras down for our rocket nets and Clovers, we had another bear sighting!
I hope everyone is enjoying the spring weather! If you look a little closer at the ground as you walk… you might even see the occasional early spring ephemeral blooming. I’m still on the lookout for trilliums in Bald Eagle and Rothrock- if anyone knows of any, could you let an enthusiast know for the photographic opportunity?

That Little Extra
It appears bugs are my new thing. My handy-dandy Google alert sent another ungulate-insect find to my inbox. This one muses about the nutritional benefits of bugs to our herbivorous friends. In particular, plant-dwelling insects.
Subsisting on plants alone leave a lot to be desired nutritionally. They are hard to digest and are low in key nutrients like phosphorus (P) and potassium (K) which are essential to ungulates. Deer are adapted for the vegetarian life with specialized digestion like rumination and fermentation coupled with volume. But they still fall short.
And it is well documented that deer readily supplement their green diet with dirt, bones, and things that wriggle. What about bugs?
Close your eyes – picture the slanted light of the morning as it touches a field or the filtered light of the forest hitting its floor. There is movement everywhere. Those that buzz and flit about are not easy prey. But eggs, pupae, larvae, and wingless species are a different story. Endophagous species develop inside of plant parts – A bug burrito!
In fact, research using DNA of fecal samples showed free-ranging cattle, goats, and sheep consumed a variety of plant-dwelling insects. Bugs may fill the gap of micronutrients specifically trace minerals like iron, sodium, and manganese. Cattle and goats ingest mainly plant-dwelling insects belonging to the orders Lepidoptera, Diptera, Hemiptera and Coleoptera – Diptera contains the highest levels of calcium and Hemiptera the highest concentrations of magnesium and iron.
You may be thinking – Deer eat plants. Of course, they are going to eat the ones that happen to be inside and on them. It’s an occupational hazard. They aren’t doing it on purpose. They can’t know what bugs they are eating.
I wouldn’t be too sure. Remember they can distinguish the phosphorus content in plants. Why couldn’t they sniff out they best bugs in the burrito? In the summer, antlers are growing and does are lactating. Calcium and phosphorus are in high demand. Why wouldn’t deer use every tool available to meet those needs?
Plant communities affect insect communities. Remember our little antler fly. Moose antlers that were more attractive to adults supported more larvae suggesting higher quality. Plant diversity and biomass influence insect diversity and biomass. But it’s complicated and not straightforward.
We know that Indian cucumber root (Medeola virginiana) and Canada mayflower (Maianthemum canadense) are two northern Appalachian spring forbs that are preferred by white-tailed deer. We also know that potassium, manganese, magnesium, phosphorus, and iron all varied based on site and species. Soooooo do the hemipteran feeding on those species in those sights also vary in their levels as well? Or do deer sniff out the mayflowers with the most scale bugs?
We’ll have to wait on that research. But I’m betting bugs are important to deer! That “little” extra they need to keep the factory online.

Greetings from the North!
Well, we caught one more deer before removing all our traps and bait from the study area. Since then, we’ve moved on to FLIR surveys and have been able to complete 3 routes per night so far. We’ve seen a few deer here and there, but not as many as we would like. It seems there are a lot of people out and about in the evenings. Can you blame them?
Woodcock are a constant presence as they perform their courtship ritual at dusk each night. If you’ve never read Aldo Leopold’s essay entitled “Sky Dance,” I highly recommend it. We did see one large male bear standing on his hind legs marking a tree. Sorry, no picture. The nights have been cold lately, it was 14° this morning, and we’ve been peppered with snow, sleet, and rain a couple of times. We’re looking forward to some warmer evenings soon!

Hello all!
Just another week left of trapping before the bittersweet finale! Between the racoons and squirrels, it’s been a challenge to keep the Clover traps open. Fortunately, they leave some traps open for our target species.
Due to the warmer weather, we spent this past week focusing on passive Clover trapping and the start of FLIRs. We did have some success and even got an adult doe collar out!
We have about a week of FLIRs done and have already had some fun finds! Plenty of porcupines out and about, a fair number of timberdoodles, various owls, assorted small mammals, and of course, our white-tailed deer. Apart from the occasional technological difficulty, our FLIR routes have been coming along very nicely.
With a total of 35 routes and the need to complete them twice, we’ll have our hands full. But for now, one more week of potential deer captures before we’re on the home stretch.
Wish us luck,

Speck
I have Google Scholar alert set up that sends me notifications whenever a publication includes “white-tailed deer.” Shockingly, I get an email every day with links to all kinds of things. They include alerts like “Analysis of different biological matrices for glucocorticoid detection in wild Cervidae and Bovidae from Europe and North America: a review.” Not really my cup of tea.
They are called…antler flies (Protopiophila litigata). Not a very creative name but appropriately descriptive. Their known distribution is eastern Canada – parts of Newfoundland, Nova Scotia, and Ontario. The predominant antler found up there is moose. Males spend their entire lives on the same antler and they are VERY aggressive defending territories, battling rivals, and attacking insects much larger than themselves.
Females arrive on antlers to feed, breed, and lay eggs in the cracks and pores in the antler surface. Larvae develop in the porous bone matrix inside antlers and emerge when they are ready to pupate. Getting to the ground without wings or legs can be tricky but the larvae spring load themselves and pop off the antler. Check out the video!
Twelve days later, adult flies emerge and return to their natal antler!
A world the size of an antler. Which made me think of Horton. I am speaking of Horton, the elephant, of course. You know, the one that lives in the Jungle of Nool and splashes in the cool of the pool. And with his big ears hears a Who!
I’m sure you think me crazy. What do antler flies and Whos have in common?
Generations of antler flies live and die on the same antler. They, like the Whos, live on a Speck – metaphorically speaking.
To paraphrase William Blake, “To see a world in a [speck] of sand…”
This is all too philosophical for a blog that centers on deer. But it’s good to keep things in perspective. The worlds of creatures are vast no matter the size of the speck.

From the Northern Crew:
Greetings from the North!
It’s been another productive week. We’ve captured another six deer and now have all 12 of our collars deployed. My crew has worked their tails off this past month trying to catch up and they’ve done an incredible job. The weather has been very cooperative, with daytime highs in the 40’s–50’s for most of the week.
We closed traps for the weekend due to warming temperatures and rain but have since reopened them for our final week of trapping.
Starting this week, we’ll begin pulling traps and transition to FLIR surveys for April. We’ve begun clearing trees from our FLIR routes, so we don’t have to do it in the middle of a survey. We have a total of 21 FLIR routes to complete and each will be done twice, so it will be a busy month. We anticipate completing 2–3 routes per night, weather permitting. Turkeys and grouse are everywhere in the Susquehannock and any day now I expect to start seeing woodcock sauntering slowly across the roads doing their rather odd dance.
Until next time, enjoy the spring weather!

From the Southern Crew:
Hello all!
The season seems to be racing to a conclusion, but there are still deer out here to be captured! We did manage to recapture a little female fawn earlier in the week. After confirming her identity, we quickly let her out. We also had another successful rocket net! A doe and fawn were safely captured, handled, processed, and released. The doe got a shiny new collar before she headed off to join her fawn!
Vernal pools are teeming with life as our twitterpated native amphibians congregate to lay eggs, and spring peepers are a near constant presence with their nightly calling. Every once in a while watching a field near sunset, we’re also treated to the calls and flights of timberdoodles.
Our trap sites still have some activity as deer seek out sustenance after a cold winter – fingers crossed we’ll have some success before the end of the season! We are of course continuing to keep these sites baited until corn needs to be off the ground for youth turkey season.
Just another week or so and then onto FLIRs.

Greetings from the North!
When it rains, it pours. Our good fortune has continued, and we were able to capture nine deer this week and collar four. We’ve been moving our trapping operations to the northern part of the Study Area, while keeping traps in the south that continue to attract deer.
The weather has been very good for trapping. We’ve had cold nights with an occasional flurry and reasonably cool days. Some days when the temperature reaches the upper 50’s–low 60’s, deer sit tight.
But when we have cold nights and cool days, it’s not unusual to see deer moving throughout the daylight hours. Those tend to be extra busy days.
Our plan is to continue to set out new traps in new places as the deer find our bait sites. Hopefully we’ll be able to catch a bunch more deer and deploy our final 4 collars over the next couple of weeks.
Until next time.

Winter has briefly reemerged for an encore after spring-like weather last week. And despite the 60-65 degree temperatures, we somehow managed to capture another 3 deer! All were fawns (so regrettably no collars were able to be put out) but it was great having an uptick in captures again.
We continue to have some deer interest in our Clover traps, along with the omnipresent non-target species (such as porcupines and raccoons). That’s more or less part of the cost of doing business while trapping in this region.
We’ve noticed some more amphibian movement as days have continued to trend up in terms of temperature. While finding rocks to help keep racoon damage at bay, a few salamanders have been revealed!
After a few pictures the rocks are always put back into place and we safely return them back to their habitat. We may briefly visit a vernal pool or two between traps and see if there are any eggs being laid (‘tis the season after all).
Rocket nets have seen a fair number of deer, but they’ve been selective and wary about coming out. These deer certainly didn’t get old by being naïve! I’m still optimistic that with time, patience, and a healthy dose of luck that we can have a few more opportunities in this region. There’s certainly no shortage of deer. We just need all our stars to align so we can have a successful and safe capture event.
Fingers crossed for the last few weeks of trapping for the 2025 season!

From the Northern Crew:
Greetings from the North!
The weather continues to be relatively warm, and the deer are active at many of our current trapping and pre-baiting areas.
We managed to catch 6 more deer in the past week, unfortunately we haven’t collared any. Hopefully, we’ll be able to get some collars deployed this week.
Our plan is to continue setting new traps in the northern part of the study area and to continue to maintain active traps in the southern part wherever deer are still visiting. Mud is the new ice and snow, not ideal but preferable to drive on. After spending so much time on ice the past three weeks, it felt like we should carry hockey sticks. The warmer weather has the grouse and raccoons busy and soon they will be joined by bears.
Until next time wish us luck and enjoy the pictures.

Hello all!
For all those excited for spring weather, I believe it is now upon us! That’s not great news for our deer trapping efforts (the deer have certainly become more elusive as all of our snow has melted), but other creatures are making their presence known! We had our first bear on camera this past week and the bright moonlit nights seem to have encouraged timberdoodle activity.
Some porcupines have teamed up with our usual gangs of raccoons at trap sites. Maybe they can teach our racoons some manners on sharing. And we’ve been fortunate enough to see/hear some owl activity at rocket nets and even caught a picture of another bobcat in one of our fields.
Curiously enough, we’ve seen a strange uptick in deer interest in our Clover traps over the past few days. I’m cautiously optimistic that we may have a few walk into traps in the upcoming week in spite of our current rain and warm temperatures.
Amid our baiting and trapping efforts this week, we also managed to pick up another dropped collar. Everyone has been able to practice and become proficient in telemetry this year – a fantastic skill in the wildlife field!
This week we’ll continue to do our best trapping deer. Please keep your fingers crossed for us!
