avian butt

_{A different kind of cake}

Used for avian characters with thinner thighs and a more feral looking teardrop-shaped behind that connects directly from the belly down to the tail_feathers with undertail coverts (visible or implied), as opposed to being broken up with more human-like rounded glutes with thicker thighs used on anthros, or even a feral mammalian butt. Essentially, it's birds without the buttcheeks (a little cheek is ok, as long as the teardrop shape is prominent).

Usually goes hand in hand with feral birds and a cloaca, but can also apply to anthro birds with different genitalia, or even clean.
