In the adult male in hreeding-plumarie the head, nape, and lesser 

 wing-coverts are cobalt-blue ; lores chestuut-brown ; ear-coverts, 

 sides of neck, back, and scapulars nearly black ; rump and upper 

 tail-coverts chestnut ; wings brown, the greater wing-coverts and 

 innermost secondaries with pale margins, the base of the outer web 

 of several of the secondaries white ; tail-feathers brown, suffused 

 slightly with blue on the outer webs ; a narrowish band down the 

 centre of the throat white ; the rest of the underparts, including 

 the asillaries and under wing-coverts, chestnut. Bill dark brown, 

 pale at the base of the under mandible. Wing with the third and 

 fourth primaries nearly equal and longest, second primary about

 claws brown. Length of wing 3-93 to 3-83 inches, tail 2-95 to 2-8,

The female very closely resembles the female of M. cinclorTiyncha, 

 but has the whole of the upper parts (except the head, wings, and 

 tail) barred. After the autumn moult each cobalt-blue and black 

 feather of the male has a pale dull chestnut margin which is cast in 

 the spring ; the chestnut feathers of the underparts have also paler 

 margins. Females after the autumn moult, birds of the year, and 

 young in first jalumage are unknown.
