Might earn me a few strange looks in the gym, but beats the hell out of being responsible for someone losing their grandma. #WearAMaskYEG pic.twitter.com/sFgrU1KIKc Retweeted by Fiera Biological

Tracked down the singing Blackpoll Warbler, but sadly, he wasn’t the bird that we deployed a #geolocator on last year! Not banded. Still took a moment to enjoy him singing (and the several other fantastic boreal breeders that are around!) #OperationBlackpoll pic.twitter.com/AkEKRlRII9 Retweeted by Fiera Biological

Wildlife Track & Sign: Snowshoe Hare

Wildlife Track & Sign: snowshoe hare

Wildlife Track & Sign: snowshoe hare. Hind Left print.
Snowshoe Hare Hind Left, Clear print

The footprint above (posted to social media on May 25, 2020) is the footprint of a Snowshoe Hare in snow, photographed on March 24th, 2020, in Elk Island National Park, Alberta, Canada.

The track patterns of snowshoe hares are very recognizable, but most people haven’t looked very closely at the details of a single print, so when they encounter a print without a track-pattern, they may not recognize it. A snowshoe hare’s foot is fully furred making details hard to pick out in most conditions, but that in itself is a detail that can lead you to a correct identification. Though the toes may register as distinct appendages, a palm pad (interdigital or metatarsal) will never register clearly, nor a heel pad with snowshoe hare, so the lack of those feature is a good clue.

Another good clue is the toe arrangement in the tracks. Four toes will register in front and hind, and that is different than most rodents which register four toes in the front tracks, and five in the hind. In addition to the number of toes, take account of the symmetry of the arrangement in an individual print. Note how the toes are loaded all to outside of the foot.

The claws of snowshoe hare are thin, fine, and sharp. They don’t always register, but the first time you see them clearly register in a splayed print, you may doubt for a moment that you are looking at the print of a bunny, and think rather that it might be something more dangerous like a lynx, a wolverine, or a dragon.

Earlier I mentioned that snowshoe hare track patterns are very recognizable, so I’d better explain. Snowshoe hares are very consistent in their use of a bounding gait. I the gait the front feet land first, and then the hind feet swing around on either side, and register ahead of the front feet. The hind feet land simultaneously, side by side.

The most likely animal you may have difficulty distinguishing from snowshoe hare in the Edmonton area would be black-tailed jackrabbit. Jackrabbit are similarly sized and shaped animals, and so they leave similar tracks. Habitat is probably your best clue for distinguishing these two species. Jackrabbits prefer open areas where they can see predators coming and use their powerful speed to escape across open terrain. Snowshoe hare on the other hand like to stay in or near the forest where they can put rose bushes, deadfall and thickets between them and any predators. Another indicator is the frequency of off-set hind feet positioning. Where a snowshoe hare only rarely positions its hind feet off-set to one another, a black-tailed jackrabbit will frequently do so.

Wildlife Track & Sign: Rock Pigeon

Wildlife Track & Sign: Rock Pigeon

#FindOutFriday, #Fieratracks

Rock Pigeon (Columba livia) in snow, Old Strathcona, Edmonton, Alberta Canada.

The footprint above (posted to social media on May 12, 2020) is the footprint of a Rock Pigeon in snow, in Old Strathcona, Edmonton Alberta, on April 2nd.

Pigeon footprints are similar to game bird (like grouse and quail) tracks in general size, and in structure except for the length of the backwards toe (called a halux). Pigeons are perching birds, and as such, have a well developed, longer, halux to help them grip branches. The halux of a rock pigeon is roughly 1/2 to 2/3 the length of its lead toe, and it will register in most tracks. Birds that spend a lot of time on the ground like grouse and quail have a reduced halux less than 1/4 the length of the lead toe, and it may not register in the majority of tracks; when it does register, it may only be the tip of the claw that does.

The left footprint of a rock pigeon, with a prominently registering halux nearly 2/3 the length of the lead toe.

The length and width of bird tracks is helpful for identification. Typical measurements of rock pigeon tracks are 6 cm long (include the halux & claws), and 4.5 cm wide.

Pigeons and grouse tend to leave an alternating (walking or trotting) track pattern. Other birds often hop, leaving a 2 x 2 track pattern.

Watch for bird tracks in snow, sand, and around puddles after a rain. Other birds that frequently leave tracks include ravens, magpies and other corvids, waterfowl, shorebirds, and robins.

2017 Wildlife Snow-tracking Workshop

Fiera Biological is pleased to announce that it will be hosting a Wildlife Snow-tracking Workshop in Edmonton, Alberta. The workshop will consist of a two-hour classroom session during the evening of Friday December 1, 2017, and a half-day in the field on Saturday, December 2, 2017.

Fiera Biological is pleased to announce that it will be hosting a Wildlife Snow-tracking Workshop in Edmonton, Alberta. The workshop will consist of a two-hour classroom session during the evening of Friday December 1, 2017, and a half-day in the field on Saturday, December 2, 2017.

This workshop is for anyone interested in learning how to identify wildlife snow tracks. Ideal for the beginner,  the workshop will cover the basics of snow track identification, but is also likely to offer something to even the most experienced wildlife tracker. Read more
