Watching Wildlife in Prince Albert National Park by J. David Henry

Browse in a bookstore and you will, more often than not, discover unexpected treasures. One of these is Watching Wildlife in Prince Albert National Park by J. David Henry, a must-read for anyone who loves animals and has spent happy holidays observing the elk, loons, and other wildlife in Prince Albert National Park.

J. David Henry is a retired wildlife ecologist, university professor, and conservation ecologist for Parks Canada. The book is self-published and describes seven wildlife species that visitors frequently encounter in the park – Whitetail Deer, Elk, Beaver, Red Fox, Red Squirrel, Common Loon, and Black Bear.

Reading this book is like holding a conversation with the author as he describes the animals that he loves so dearly and shares so many fascinating tidbits of information.

White-tailed deer

Whitetail Deer
Whitetail deer hide their newborns and go to great lengths to conceal them successfully: “After giving birth, the doe immediately eats the placenta and the umbilical cord, but she also grazes the ground vegetation where the birth took place. She consumes old leaves, herbs, grass and even soil – any object that has a detectable odor of the birthing of her fawn, removing any sign that might alert a predator that a young fawn is hiding in this area. If you are lucky and a good observer, during mid-May on a forest hike you might spot one of these birthing places. The sign to look for is a small patch of ground where the vegetation has been ‘mysteriously’ clipped close to the ground.

elk

Elk
Male elk are in their prime when they are 7-10 years old and will have a harem of 20 or more females. But it’s unclear who is in charge of the harem. The females may be the ones who lead the harem to a new location and they may choose to be included in the group in order to gain protection from other males.

Common loon

Loon
Although loons mate for life, they do not migrate or spend the winter together. Henry has observed the birds’ springtime reunions and says, “I can tell you that the excitement and joy that the birds express upon seeing one another is deeply moving. Both birds greet and display to each other in a manner that can only be described as ebullient. There is much splashing and rushing towards each other. There is jumping and dancing on the surface of the water, but also quiet bill dipping together as well as gliding along side by side.

Beaver
Beavers sharpen their teeth by grinding the top incisors against the bottom ones and vice versa. If a beaver is cutting down a large tree, it will stop every 10 to 15 minutes to rest and sharpen its teeth. You may even see flecks of tooth material shooting out the sides of its mouth.

Red fox

Red Fox
Red fox, like cats, can see well in the dark thanks to a shiny membrane on the back of the eyeball. It acts like a mirror so light passes over the retina twice instead of just once.

squirrel

Red Squirrel
Red squirrels will harvest up to 14,000 seed-bearing cones in preparation for winter. The cones are often stored in large underground middens with a network of tunnels. The middens are easy to identify thanks to the pile of cone scales that are discarded above ground.

Black bear

Black Bear
If a mother bear spots danger, she signals to her cubs and they immediately climb a tree. Then they promptly fall asleep until their mother calls to let them know the danger is past and they can come down again.

Buffalo

Plains Bison
A small herd of plains bison roams freely in the southwest corner of Prince Albert National Park (Stewardship: A Critical Role for Landowners). The story of how they came to be there is an interesting one and well documented in the book. Unlike black bears, bison calves are born in a well-developed state. By the time they are three hours old, they are able to run and keep up with the herd and will start nibbling grasses immediately, although most of their nutrition will come from the mother’s milk during the first six months of life.

Watching Wildlife in Prince Albert National Park by J. David Henry is available for purchase at McNally Robinson Booksellers in Saskatoon. It is available at the Saskatoon Public Library.
