White-tailed Deer Giving Birth

deer and fawn alert _H6A8525 copy (002)White-tailed does give birth at the end of May and the beginning of June. A doe giving birth for the first time usually has one fawn; in subsequent years, two or three fawns are common. For the first three or four days after it is born, a fawn is odorless and is well camouflaged thanks to its spotted coat.

During this time the mother leaves her offspring (who remain motionless during her absence) and goes off to feed. (It can be three weeks or so before the fawns follow their mother when she feeds.) The doe stays away as much as possible from her fawns during these first days and weeks to prevent her own body scent from giving away their location. She returns to nurse her young eight to ten times in a twenty-four-hour period.

People discovering what looks to them like an abandoned fawn should know that although the doe may not be in sight, she most likely is within hearing distance and is probably watching them. The fawn has not been abandoned and should not be disturbed. (Thanks to Erin Donahue, who took this photograph.)

Red Fox Kits Maturing

5-25-18 red fox kit_U1A4366Time is marching on…the blue eyes of Red Fox kits are turning brown, as they do once a kit is around two months old. Their coat is slowly being replaced by the reddish hairs for which they are named. While kits still spend most of their time close to their den, individuals will take short exploratory walks by themselves. Frequently they accompany their parent on forays during which they are instructed on the finer points of being a successful predator.

Black Bear Yearlings Still Nursing

Female Black Bears mate every two years. Their young are born in January or February and  they stay with their mother for the first year and a half of their lives. Although many sources state that cubs are weaned during their first summer, I discovered firsthand that young bears continue to nurse well into their second year (even though they’ve been eating solid food since they were a few months old).

Two different times while I was within a stone’s throw of her, the mother lay down on the ground and her yearlings proceeded to nurse. Soon, in May or June, shortly before she mates, the mother will drive her yearlings away, forcing them to disperse. Life’s lessons have been taught. By their second spring the yearlings have learned the basics from their mother: what to eat and where to find it, how to defend themselves, where to find safety and how to interact and communicate with other black bears. and they should be able to survive on their own.

Black Bear Yearlings Active

Just like other young mammals, young Black Bears are highly energetic. When they aren’t sleeping, they can be found wrestling, biting, grooming, climbing and playing hard with each other. All of these activities, including the pictured yearlings mock-fighting, equip them with necessary survival skills.

Exploring With Senses

(Several times I had to shoo one of them away, for fear their mother might object to its close proximity to me.) Some of this exploration serves as the beginning of scent-marking that they will use to communicate with other bears their entire lives, while some of it appears to be just plain fun.

Tolerant Black Bear Mothers

The yearlings continually challenge their mother’s patience as well as each other’s to see just how much will be tolerated. They climb on, bite, claw and test their mother in much the same manner as toddlers do their (human) mothers. At the same time, when she demands that they follow her instructions, such as climbing a tree when danger approaches, they immediately obey.

Black Bears Emerging From Hibernation

3-26-18 black bears sleeping 1545

A year ago, in April 2017, while following Black Bear tracks in New Hampshire, I had the good fortune to encounter the bears themselves. Because Black Bears have started coming out of hibernation (April is when most do so) I felt it was timely to share some of my photographs and observations of that encounter. (I did not do so a year ago for fear of bringing attention to and thereby disturbing these bears.)  As I followed the bear tracks, I eventually came upon a refuge, or “babysitter,” tree – where bears rest and cubs/yearlings take refuge when their mother goes off foraging or when she senses danger. I had read about such trees, but never discovered one myself. It was very recognizable — a very large White Pine surrounded on the ground by bear scat and gnawed saplings – fresh signs that bears frequented this area. At the base of the tree were several large “bowls” or indentations in the pine needles that looked as if large animals might have bedded down repeatedly in them, forming nests.

I continued tracking, eventually turning around to head back to where I entered the woods. On my return I passed by the babysitter tree again. To my utter delight I discovered a mother bear with her three yearlings fast asleep in the beds at the base of the tree. It was snowing lightly, and I surmised that this family had recently emerged from their deep winter’s sleep and was still a bit groggy. (Adult males are the first to emerge; females with cubs are the last.) While the yearlings slept on, the mother opened her eyes and decided to tolerate my presence for the next couple of hours. In Naturally Curious posts this week and next, I will share this once-in-a-lifetime experience with you as well as the behavioral observations I made.
