The reason blue jays are screaming is a way to stay in touch and communicate with other blue jays.
The call helps mates keep track of each other, and also serves to assemble the troops, so to speak, in response to a threat.
Blue Jays do like bird houses but mostly blue jays prefer open platforms instead of enclosed spaces for a bird house.
Provide a floor area of about 8 x 8 inches with a ceiling also around 8 inches high.
A sloping roof with open sides and front is perfect.
Birds that generally nest on trees are more likely to nest on houses as well, just like the Blue Jays.
Try installing your bird house on the side of your garage or set it to a tree.
Blue Jays are very smart and really intelligent birds.
Blue jays are a member of the Corvidae family, which includes crows, ravens and magpies.
The family is regarded as the most intelligent of the bird species.
Blue Jay birds have a high brain-to-body mass ratio, similar to the great apes.
Crows and ravens, in particular, enjoy showing off their intelligence.
Blue Jays are not inherently mean.
Like most birds and animals, their aggression has to do with protecting their territory and their young.
The mean streak associated with them may be due to their preferred defense mechanism; forming a mob.
The blue jay is a passerine bird in the family Corvidae, native to eastern North America.
It lives in most of the eastern and central United States; some eastern populations may be migratory.
Resident populations are also in Newfoundland, Canada; breeding populations are found across southern Canada.
Recently, the range of the blue jay has extended northwestwards so that it is now a rare but regularly seen winter visitor along the northern US and southern Canadian Pacific Coast.
As the two species' ranges now overlap, C. cristata may sometimes hybridize with Steller's jay.
Ravens and other members of the corvid family (crows, jays, and magpies) are known to be intelligent.
They can remember individual human faces, expertly navigate human environments (like trash cans), and they even hold funerals for their dead.
