Do Blue Jays Eat Other Birds

Blue jays are naturally granivorous (seed-eating). They are usually social but only around their own kind. Given their size and protective behavior, they genuinely bully other birds, even humans, and other predators too. 

But do blue jays eat other birds? Not under regular circumstances. They may feed on smaller birds or their younger ones, especially the fledgling only when food is severe. Also, keep in mind that, blue jays are intelligent birds. 

They may occasionally raid the nests of smaller birds in search of eggs. However, it isn’t a significant part of a blue jay’s regular diet. So, where does it all begin? 

It all started with a myth. Because the blue jays belong to the Corvid family, most of the members of this family generally hunt on smaller birds such as crows and ravens. 

This is where it started that, the blue jays also eat other birds. We have put together some other common myths related to the Blue Jays too. Let’s read. 

Myths About the Blue Jays

Here are some common misconceptions about blue jay birds. Be aware of them to prevent further confusion. 

1) They Target Adult Birds

It’s a common misconception that blue jays attack all kinds of birds. But in truth, they rarely target adult birds. Blue Jay potentially targets eggs and nestlings of other birds, which are easier to access and consume than adult birds. 

2) Blue Jays Are Predator Birds

This myth is pushy because the blue jays belong to the Corvid family. However, they are not specialized bird predators. Their food list involves seeds, nuts, fruits, and insects. While they may occasionally eat eggs or nestlings, this behavior doesn’t define their overall diet. 

3) They Solely Depend On Protein

A varied diet is the best solution for the survival of blue jays, and any other birds. No species from the animal and bird kingdom can rely on one type of food only. It would make them vulnerable and also won’t satisfy all the nutrition they need. 

Keep in mind, that the versatile selection of diet based on season and food availability contributes to their resilience in the wild. 

In summary, Blue jays are primarily seed-eaters, with a selection of nuts, fruits, and insects like any other birds. They are usually not predators but can be under special circumstances such as food scarcity or competition, nesting habitat, or change of season.
