Jays are a paraphyletic grouping of passerine birds within the family Corvidae. Although the term "jay" is a folk taxonomy, most or all of the birds referred to as jays share a few similarities: they are small to medium-sized, usually have colorful feathers and are quite noisy. These superificial characteristics set them apart from most other corvids such as crows, ravens, jackdaws, rooks and magpies, which are larger and have darker plumage. Many so-called "jays" are genetically closer to these other corvids than other jays, however.
Systematics and species
Jays are not a monophyletic group. Anatomical and molecular evidence indicates they can be divided into a New World and an Old World lineage (the latter including the ground jays and the piapiac), while the grey jays of the genus Perisoreus form a group of their own.{{cite journal|last1=Ericson|first1=Per G.

In culture
=Slang=
The word jay has an archaic meaning in American slang meaning a person who chatters impertinently.{{cite web| title = Jay | quote = An overly talkative person; a chatterbox.| publisher = freedictionary.com| url = http://www.thefreedictionary.com/Jay}}{{cite web|url=http://www.merriam-webster.com/dictionary/jay|title=Definition of Jay by Merriam-Webster|date=26 October 2024 |publisher=Merriam-Webster, Inc.}}
The term jaywalking was coined in the first decade of the 1900s to label persons crossing a busy street carelessly and becoming a traffic hazard.{{cite web|url=http://www.merriam-webster.com/dictionary/jaywalker|title=Definition of Jaywalker by Merriam-Webster|date=28 August 2024 |publisher=Merriam-Webster, Inc.}} The term began to imply recklessness or impertinent behavior as the convention became established.{{OED|jay-walker}}
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.{{cite news|title=Writer lobbies for new word to describe jays|url=http://www.vancourier.com/Writer-lobbies-for-new-word-to-describe-jays-1.776734/|access-date=January 2, 2014|newspaper=Vancouver Courier|date=January 2, 2014}}{{cite news|title=British Ornithologists' Union: What say ye countrymen to a jabber of jays?|url=http://www.bou.org.uk/what-say-ye-countrymen-to-a-jabber-of-jays/#comments/|access-date=January 6, 2014|journal=Community News|date=January 6, 2014}}
