These examples appear to be all fully adult, and differ 

 from each other only in the under tail-coverts, which are 

 bright sulphur-yellow in some to almost white in others; the 

 under wing-coverts vary in a similar manner. 



The wing-measurements of the males are 2 , 8-3 , inches, 

 females 27-2"95. 



[This species is quite common in wooded districts and has 

 rather a pleasing call, with which different individuals answer 

 one another. It is in this way that specimens of the bird can 

 be most easily procured ; its habits of living in the thick 

 parts of the trees, hidden in the foliage, would otherwise 

 make it difficult to find, Mere it not for its call. — W. F.'\
