Where did all my Blue jays go?

Amy in short: Regionally, there’s no evidence the abundant blue jays have gone anywhere. Individual yards may be a different story.

Why are Blue jays scarce?

This is mainly because it’s their nesting season, and they don’t want to blow their cover by being excessively chirpy. Young jays are more likely to migrate than adults. Some of them scatter far and wide towards the south and stay the following winter and then migrate again to the southern regions.

Why are Blue jays declining?

I found that the main cause of decline in numbers is because of habitat loss. Millions of birds lose their lives and homes to deforestation or climate change every year. Blue jays especially suffer from this because they mostly eat berries and other things that would fall from trees and their habitat.

Are Blue jays endangered?

Do Blue Jays carry disease?

For example, West Nile virus—a disease that occurs often in the crow family, including jays and magpies—is carried to people by mosquitoes, not by birds. In order for people to get this disease, a mosquito that has bitten a bird with the virus must then bite a human.
