Mating Behavior of Blue Jays

Breeding Season

The spring and early summer are prime mating seasons for blue jays. Depending on latitude and climate, the breeding season might be rather different.

Pair Formation

The nest is constructed using natural materials such as twigs, bark, grass, and other organic matter. The male helps the female build a home by bringing her food and protecting the nest.
