The Corvidae family contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs and nutcrackers. These species are grouped into subfamilies that are outlined in the table that follows. Beware that  names such as jays, magpies, or treepies are not always assigned in a consistant manner. For example, the black magpie (Platysmurus leucopterus) belongs to the treepie subfamily.

SUBFAMILY MEMBERS
Corvinae True crows of genus Corvus includes the crows, ravens, rooks, jackdaws.
Corvinae (continued) Jays of genus Garrulus, nutcrackers of Nucifraga,  magpies of Pica, ground-jays of Jay Podoces, and the piapiac of Ptilostomus, and Stresemann's bush-crow of Zavattariornis.
Cissinae Green-magpies of Cissa and the blue-magpies of Urocissa.
Cyanocoracinae Most of the species that are named "jay".
Crypsirininae Treepies
Perisoreinae Three jay species of Perisoreus and Magpies of Cyanopica

Corvids are medium to large in size, with strong feet and bills, and a single moult each year (most passerines moult twice). Most species have bristle-like feathers covering their nostrils. They are omnivores having a varied diet of animal and plant material. Makes average slightly heavier than females. Corvids are found worldwide except for the tip of South America and the polar ice caps.


Subfamily Cissinae - Magpies



This covid subfamily contains two magpie genera: the green-magpies of Cissa and the blue-magpies of Urocissa. These are Asian magpies with the greens being centered around Southeast Asia and the blues averaging more northern in location. Both magpie groups eat more vertebrates and invertebrates than plant material.

Other magpie not in this subfamily are in genus  Cyanopica and genus Pica.
