Apparently, Blue Jays and Green Jays separated about 7 million years ago. The Blue Jay resides in temperate climates and is common in the eastern states. Green Jays are tropical birds in Mexico and Central America.
However, as the climate changes, the ranges of these birds have begun to overlap. And here they have found a hybrid. The Blue Jay is expanding west and the Green Jay is expanding north.
This bird has traits of both, hanging with blue jays, and still have the vocalizations of a green jay. FULL STORY
Interesting.
