Systematics and species
Jays are not a monophyletic
group. Anatomical and molecular evidence indicates 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
. The crested jay
) is traditionally placed here, but its placement remains unresolved; it does not seem to be a corvid at all.
The word jay
has an archaic meaning in American slang meaning a person who chatters impertinently.
The term jaywalking
was coined in 1915 to label persons crossing a busy street carelessly and becoming a traffic hazard.
The term began to imply recklessness or impertinent behavior as the convention became established.
In January 2014, Canadian author Robert Joseph Greene
embarked on a lobbying campaign among ornithologists in Europe and North America to get Merriam-Websters Dictionary to have a "Jabber of Jays" as an official term under bird groups.
