Unicolored Jay

Aphelocoma unicolor

Medium124 gForest

The unicolored jay is about 34 cm (13 in) long. The nominate subspecies A. u. unicolor weighs about 125 to 150 g (4.4 to 5.3 oz). The sexes have the same plumage. The nominate subspecies is entirely deep blue to purplish blue that is somewhat darker on the sides of the head and the throat. Juveniles are a slightly bluish gray that is duller than adult plumage. Subspecies A. u. griscomi has the same plumage as the nominate. A. u. guerrerensis is the most purplish subspecies, A. u. concolor is a paler blue than the nominate, and A. u. oaxacae is somewhat darker than the nominate. Voice: Though recordings of unicolored jay vocalizations come from most of its range, detailed analyses come primarily from the Montebello studies. The birds there made hundreds of variants of their calls though many were only subtly different from each other. The calls were described as grating/harsh, musical/resonant, whistled, loud, and soft.
