The Corvidae - Crows and Their Relatives

The family Corvidae comprises a medium sized group of passerine (perching) birds. It is a reasonably well known family, however in Sibley and Monroe's new phylogeny, many other traditional families have been incorporated into the family Corvidae giving it a huge and unwieldy 649 species. Here however I have stayed with the traditional Howard and Moore classification of the family and will treat the other families independently as well. The Corvidae in this scheme is made up of about 119 species in 26 genera.
