Cat Track Clarification

e-tape and tracks 105I knew this post might stir up some controversy, but it far exceeded my expectations! I did take photos of the tracks with a tape measure, but they weren’t as clear as the one I chose to use for the post. Pictured here is the clearest measured track photo. With a bit of work, using the tape as a reference, one can see that the individual tracks measure roughly 2 ¼ “ wide by 2 ¼” long. ADULT cougar tracks = 2 ¾” – 3 7/8” L x 2 7/8” – 4 7/8” W. Remember that the person who saw this cat was definite about it being a JUVENILE cougar, judging from its size. Bobcat tracks = 1 5/8” – 2 ½” L x 1 3/8” – 2 5/8” W. House cat tracks (unlike the bobcat, house cats have a long tail, so might be more likely to be mistaken for a cougar?) = 1” – 1 5/8” L x 7/8” – 1 ¾ “W. These measurements rule out a house cat. They are within the range of a juvenile cougar or adult bobcat track, but only the cougar has a long tail (observed by eye witness). In addition, the stride (defined here as a measurement taken from the heel of one footprint to the heel of the same foot in the next footprint) of this cat was roughly 32″. An adult cougar’s stride is 32″ – 44″. A bobcat’s stride is 22″ – 26″. Skeptics are welcome to believe it was a bobcat. I trust my friend’s eyesight and the tape measure enough to believe it was a cougar. Many thanks for your engagement and comments!

Cougars in New England

1-15-16  cougar tracks  022Are there cougars/mountain lions/pumas/panthers/catamounts (all common names for the same species) in the Northeast? There have been many sightings in every New England state, but official Class 1 confirmation (body, photographs or DNA) only in Connecticut (2011), Massachusetts (1997) and possibly Vermont (1994-mixed DNA results). It depends on whom you talk to, but the consensus of most wildlife biologists is that there may not be a breeding population yet, but they are here (some thought to be of captive origin). There is no question that cougars are extending their range eastward. Through DNA analysis a cougar killed by a car in Connecticut in 2011 proved to have come from the Black Hills of South Dakota. It had traveled about 2000 miles to the East Coast over 2-3 years.

A recent sighting by a friend had me out on snowshoes recently, trying to find traces in the woods where she had had an excellent view of what she identified as a juvenile cougar crossing the road in front of her car. The pictured tracks are what I found and followed. They are definitely cat tracks! Further investigation revealed several sites where parts of a deer had been cached, with typical (of a cat) sheared deer hair (see photo insert) evident. Unfortunately, there was no scat to be found, so adequate DNA wasn’t available for analysis, and thus, it is but one of 50 to 60 reported-but-unconfirmed cougar sightings that Vermont gets each year. It may be officially unconfirmed, but there is no question in my mind which species of cat I was tracking. (Thanks to Squam Lakes Natural Science Center for cougar photo op.)
