There are two types of Gloster Canary, the crested bird itself and its plainheaded counterpart, each of which is an integral part of breed as a whole. The title of 'Corona' is for the crested form and 'Consort' for the plainhead.
Two crested birds are seldom mated together, mainly on account of a lethal factor that is involved.
General appearrance of the Gloster Canary: Crest: Neatness, regular, unbroken round shape, eye discernible, with definite center. Consort: Head broad and round at every point, with good rise over center of skull.
