Here are a few cool facts about these lovely J's.

Most songbirds wait until spring to nest, but not this tough J of the North.

They nest during winter, and sometimes a pair may even begin nest building during the later part of February.

In the southern part of its range, eggs are laid on every tour and the later part of merch.

I remember my first and well only Canada J nest, and as I watched the female nestled down in her nest on a stormy and cold winter day minus 20 degrees Celsius, I was touched by her devotion to those eggs.

In order to be able to nest in such conditions, the nest needs to be well insulated.

Something like hundreds of cocoons fill the gaps of the dry dead twigs.

Other things such as Lincoln or strips of bark or closer to the center, and the cup itself is lined with hundreds of hair, fur or feathers.

The nest is also usually located on the south side of the tree, allowing the female and the nest to receive direct sunlight.

Interestingly, Canada Jays will not attempt a second brood in mayor.

June seems odd, considering they have seemingly plenty of time to have another one since they nest much earlier than other birds.

Maybe because finding and storing food large quantities of it is essential to a candid Ajay survival in winter.

So instead of having another brute, they prefer to spend their summer storing away as much food as they possibly can to survive the harsh winter season.

Canada jays have a pretty amazing way of storing food any food they want to hide away into.

The trees are worked back and forth in their moods so that the food item becomes covered with sticky saliva from its greatly enlarged the library glands.

Once that is done, they then stick the food behind a piece of bark or under some Lincoln and anywhere else on a tree they can stop it into.

In the summer days near the Arctic Circle.

Cash is a day by winter that Jay will have accumulated quite a lot of food stores, which it will need in order to survive over the coming seven months.

They have to be nifty, though other animals may steal their stored food.

So to help conceal them, they cover up food stores with a piece of bark or Lincoln.

And the food stores aren't all close together, either.

They spread them evenly through their territory to prevent any huge losses of another.

It's apparently a good tactic against competitors To the most astonishing part, though, is that Canada Jay's actually remember where they hid all of this food, which is one main reason why Canada Jay's can survive winter without migrating Juvenile Canada J's just out of the nest look quite different from their parents, like an entirely different species.

In fact, the great pioneering naturalist John Jack Audubon thought they belonged to a new species when he first encountered them back in the 18 thirties.

But once the city black juveniles have completed their first moult in July and August, they look much more like the adult Canada J's.

Speaking of Juvenile Canada, J's sibling started cuddly and sweet, but that quickly changes when they reach between the ages of 55 65 days.

Fighting becomes frequent, with the end result of expelling its former nest mates from the Natal territory.

This means that the dominant juvenile, usually a male will accompany its parents alone, gave a summer, fall and winter of its first year.

The ejected birds, majority of which are females, quickly leave, and a few may succeed in attaching themselves to unrelated pairs, particularly those that have failed in their own nesting that year.

Most dejected juveniles aren't so lucky, though about 80% of them are dead by their first atom, as opposed to only 50% of the dominant juvenile's that get to stay with their parents and benefit from their example and protection.
