Greater blue-eared starling
The greater blue-eared starling or greater blue-eared glossy-starling (Lamprotornis chalybaeus) is a bird that breeds from Senegal east to Ethiopia and south through eastern Africa to northeastern South Africa and Angola. It is a very common species of open woodland bird, and undertakes some seasonal migration.
The greater blue-eared starling is a 22-cm long, short tailed bird. This starling is glossy blue-green with a purple-blue belly and blue ear patch. Its iris is bright yellow or orange. The sexes are similar, but the juvenile is duller and has blackish brown underparts.
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. source
