Jays are several species of medium-sized, usually colorful and noisy, passerine birds in the crow family Corvidae.

The namesjay and magpie are somewhat interchangeable, and the evolutionary relationships are rather complex. For

example, the Eurasian Magpie seems more closely related to the Eurasian Jay than to the Oriental Blue and Green

Magpies, whereas the Blue Jay is not closely related to either.

Systematics and species

See classification box for relevant genera links. Traditionally, the Crested Jay (Platylophus galericulatus) is placed

here, but apparently this is not correct, as suggested by anatomical and molecular evidence[citation needed]

. Its

placement remains unresolved; it does not seem to be a corvid at all. According to Ericson et al. (2005), jays are not

a monophyletic group. Rather, they can be divided into an American and an Old World lineage (the latter including

the ground jays and the Piapiac), while the gray jays of the genus Perisoreus form a group of their own. The Black

Magpie, formerly believed to be related to jays, is classified as a treepie.

In culture

Slang

The word "jay" has an archaic meaning in American slang meaning a person who chatters impertinently.[1] The

word also means a foolish or gullible person.

The term jaywalking was coined in 1915 to label persons crossing a busy street carelessly and becoming a traffic

hazard.[2] The term began to imply recklessness or impertinent behavior as the convention became established.

("jay-walker" [3]. Oxford English Dictionary (3rd ed.). Oxford University Press. September 2005.).
