Gerygone albogularis, Gould, Birds of Australia, fol., vol. ii. pi. 97. 



This, so far as I know, is a stationary species, and is 

 abundantly dispersed over all parts of New South Wales, 

 but evinces a greater preference for the open forests of 

 Eucalijpti than for the brushes near the coast. I found it 

 in considerable numbers in every part of the Upper Hunter 

 district, nearly always among the gum-trees, and constantly 

 uttering a peculiar and not very harmonious strain. It is 

 very active among the small leafy branches of the trees, where 

 it searches with the greatest avidity for insects, upon which it 

 almost exclusively subsists, resorting for this purpose to trees 

 of all heights, from the low sapling of two yards high to those 

 of the loftiest growth. 



I killed young birds in January, but was not so fortunate 

 as to discover the nest. 



The sexes are nearly alike in plumage ; but the young of 

 the year are distinguished from the adult by the throat being 

 of the same colour as the breast, instead of white. 



Crown of the head, ear-coverts, and all the upper surface 

 olive-brown ; throat white ; chest and all the under snrface 

 bright citron-yellow ; two centre tail-feathers brown, the re- 

 mainder brown at the base, above which is a bar of white, 

 succeeded by a broader one of deep blackish brown ; the tips 

 of all but the two middle ones buify white on their inner 

 web ; bill blackish brown ; irides scarlet ; feet blackish brown 

 in some specimens, and leaden brown in others.
