Some damage to this old one, early 19th c., but rare to find these in yellow, and of course one wants to be a good girl. What I believe is being depicted is a good girl of a bird, about to receive (at least as i imagine it!) a regurgitated treat from her open-beaked partner! Though maybe just a peck!
2 1/8 x 2 1/4 t x 2 3/4 handle. No repairs, but two hairline cracks as evident, some glaze loss around the rim, and some loss to the transfer of "girl", I believe original to it. Stable and not especially delicate. Hand-painted decoration on the handle.
