Blue jay

Blue Jays are passerines native to the Earth Kingdom. They have coalesced into mainstream society, and can often be found alongside humans in developed regions.

Anatomy
Blue Jays, as their name suggests, are predominately blue, save for their white underparts. Blue Jays have a notable crest atop their head, identical in color to their plumage. The crests are crowns of feathers, lowered and raised in accordance to a particular Blue Jay's mood.

The Blue Jay's plumage is lavender-blue to mid-blue in the crest, back, wings and tail. The entirety of the Blue Jay's face is also lavender-blue, save for the feathers surrounding the eyes, which are white in coloration. The underside is also white, surrounded by a dark blue trimming, a feature also seen in the wings. Several dark blue feathers are scattered among the creature's tail. Blue Jays have light brown talons as well as beaks.

Connection
The Blue Jay is unhybridized. As such, it is directly comparable to the real life blue jay.

Behavior
As aforementioned, Blue jays have adapted to urbanization, and can be found in heavily settled areas, such as Ba Sing Se. However, this does not mean that Blue Jays are dependent on humans for their survival, as evidenced by the flock that still lives throughout the abandoned city of Taku.

When excited or aggressive, a Blue Jay's crest may be fully raised. When frightened, on the other hand, the crest bristles outwards, brushlike in appearance. When an individual jay is feeding among others or resting, the crest is flattened to the head. Blue Jays are passive creatures, and instinctively fly away upon sensing danger. Bato of the Water Tribe
