There are four accepted subspecies:[3][4] The greater blue-eared starling is a 22 cm long, short tailed bird.

The populations from southern Kenya southwards are smaller than northern birds and are sometimes considered to be a separate subspecies, L. c. sycobius.

The lesser blue-eared starling is similar to this species, but the blue of the belly does not extend forward of the legs.

The greater blue-eared starling has a range of musical or grating calls, but the most familiar is a nasal squee-ar.

The greater blue-eared starling nests in holes in trees, either natural or excavated by woodpeckers or barbets.
