Outdoor Adventures: Tracking Animals in Winter

Siggy walk .jpgA large majority of my free time is spent wandering through the woods and fields with my dog in tow (alright, normally I’m the one in tow as he impatiently waits for me to keep up). Although I am occasionally rewarded with a neat critter sighting, most of the time, my pup does a pretty good job scaring off any wildlife within the vicinity. Instead, I’m left to look for signs that animals have been there: tracks, scat (the very scientific word for poo), feathers, bones, nests or other homes, rubs, scrapes, chewing marks, etc. Of course, this is assuming my dog hasn’t destroyed and/or eaten any of the artifacts before I can find them. During the summer, when our landscapes are bursting with vegetation, birds, insects, and more, these signs can be hard to notice! Unless you’re traversing a mud pit, tracks largely disappear in the carpet of last year’s leaves, grasses, and under story plants. But in winter, if it’s snowy,  it’s like a veil has been lifted and animals are no longer capable of sneaking about undetected. Suddenly our yards, forests, and fields come alive with activity, all documented by footprints left behind. Following animal tracks in the snow is one of my all time favorite winter activities (… okay, I love everything about winter).

Deer and Turkey TracksSo how do you begin to know what kind of tracks you’re looking at? We’re going to break it down for you. Chances are, if the track is in the snow, it belongs to a bird or a mammal. Our reptiles and amphibians are hibernating for winter and our fish obviously don’t leave tracks in the snow. Bird tracks, as a group, are pretty easy to identify and we’re not going to delve into identifying bird tracks by species. I’m not sure that anybody delves into that! So the first thing you need, is a field guide to mammals in you area (see resources at the bottom). Once you identify a few characteristics, the list of potential mammalian suspects narrows pretty quickly. First, there are two major things a beginner tracker needs to observe.

  1. Clear, Individual Print –  Yes, it must be clear! Not all snow is going to provide you with a crisp print. Super dry, light, fluffy snow isn’t the best for tracks. Neither is super deep snow, as the actual track is so far down you can’t see it. If you don’t have a clear print with distinct details, skip ahead to number 2. If you do find a high quality print, there are 4 aspects you want to observe: toes, shape, claws, and size.  

A. Number of toes – groups of mammals can be identified by how many toes are in the print. Some mammals may have different numbers of front and back toes, so be careful!

B. Overall shape – Is the track mostly round? Oval? Does it look human-like, but tiny? Is it heart-shaped? Are the toes very long and skinny? Noticing the overall shape can help identify the correct group of mammals. Many animals have differently shaped front and hind tracks – do you see two different shapes?

C. Claws – are there claw marks present? These can be very difficult to see at times, but they can also be really helpful, especially when identifying between dog and cat groups (cats have retractable claws, so they typically don’t show in their prints).

D. Size – It can be very useful to bring a small measuring tool with you on your walks to determine the front and hind track size.  Make sure if you see two different prints, as in a front and hind track, to measure both if you can. If you don’t have a measuring tool with you, try to get a picture with something in it for scale so you have an idea later how big or small the print was.

2. The Track Pattern – Even if you have deep snow or unclear prints, you can usually still study the track pattern, or the gait of the animal. There are four basic track patterns: walking, galloping, bounding, or waddling.

A. Diagonal Walking – Created when an animal moves its right hand and left foot at the same time, then its left hand and right foot at the same time. Tracks are fairly equally spaced and appear as “double” prints. Diagonal walkers include: cats, dogs, hoofed animals, opossums, and badgers. You’ll also want to note the stride, or the distance between two hind tracks. Strides of diagonal walkers are typically about the shoulder to hip distance of an animal, so this can help you quickly identify the relative size of the animal that left the print.

Diagonal Walker

Direct Register: When the hind track lands directly on top of the front track. Includes cats and fox.

Indirect Register: When the hind track overlaps a little behind the front track. Includes all other diagonal walkers.

B. Galloping –  Created when the larger hind feet land in front of the smaller hind feet. Gallopers include: rabbits/hares, squirrels, chipmunks, mice, voles, & shrews.

gallop walkers

C. Bounding – Created when the front feed land together at the same time, and then the back feet land where the front feet were. Bounders include: weasels, otter, mink, marten, & fishers.

Bounder

D. Waddling (aka Pace Walking) – Created when the weight of an animal shifts from side to side – both the right hand and foot move forward, then both the left hand and foot move forward. Waddlers tend to be heavy-set mammals, including: bears, porcupine, muskrat, raccoons, beavers, & skunks.

Gait patterns

Keep in mind, these are general rules for walking animals and there are always exceptions to rules! In addition, the speed of the animal and the terrain can affect the track pattern created. These general rules should be used for walking animals on relatively flat ground. Once you’ve mastered this, you can dig deeper into tracks made at various speeds and so on.

Here are some of the tracks I’ve come across in my wanderings.

So head out there and enjoy! Take a small ruler or measuring device, a notebook, and a small camera on your wanderings. Then you can always ID them later, hopefully by the fire with a cup of hot chocolate!
