This small flycatcher (10cm - 4 in) although omni-present in Coronado is difficult to see as its natural habitat is within trees. It is very nervous and wags its tail continually. Tody has a black head and wide tail, grey back and a vivid yellow underside.. Its wings are black and have small yellow markings.

There is also a Black headed Tody which is very similar, differing from the common Tody by a white throat and a dull yellow back.
