Crows and Jays

 
Crows and jays are in the Corvidae family more often known as the crow family or corvids. Corvids are found all over the world except for New Zealand, the southern part of South America and the North/South poles. Corvids are very intelligent and have some of the best spatial memory of any animal.

Blue Jay (Cyanocitta cristata)

• Blue Jays sometimes mimic the calls of hawks and this warns other jays that a hawk is around or can be used to trick other species into thinking a hawk is around
• They love to eat insects, nuts, and seeds. Sometimes they will eat dead or injured animals and steal eggs from other nests. They also sometimes store food in secret places for later
• Blue Jays are excellent mimics and can imitate many different sounds. Captive Blue Jays have sometimes learned to imitate human speech and meowing cats

Identification Information:

• Size: Robin sized (Small/Medium)
• Color: shades of blue all over the top, with black and white mixed in, white or light grey on belly
