these nests of basketwork, from which they hang, fanning 
their wings the whole time to and fro like birds with their 
feet caught in meshwork. 
In June the young males are similar in plumage to the 
adult females^ but have the upper parts uniformly washed 
with olive-yellow and the under parts with bright yellow ; 
upper mandible brownish horn-coloured^ lower mandible 
paler; iris brown ; legs and feet flesh-coloured. By the end 
of the year the feathers from the breast downwards become 
white, turning to earthy brown on the sides of the chest and 
flanks. The olive-yellow wash also disappears from the 
brown feathers of the upper parts, with the exception of the 
crown, which still remains olive-yellow. In the beginning of 
February a direct moult is undergone. The scapulars and 
rump are the first to assume the adult plumage, and the iris 
becomes red. By the end of March the bill has become 
entirely black; iris bright orange; feathers of the crown, sides 
of face, chin, and throat black ; collar deep chestnut ; mantle 
and back particoloured ; remainder of the under parts 
white, splashed with bright orange-yellow; legs and feet 
light brown. 
About the middle of May the complete adult plumage has 
been assumed. 
I do not think that the adult male assumes a winter 
dress, since I have observed individuals throughout the year 
in the same plumage as that of the breeding-season.

Breeds in May, The nests, constructed of coarse grass- 
blades and lined with fresh leaves, are suspended underneath 
the fronds of the palm-tree in damp situations. A large 
number may be found together. Both male and female share 
in the incubation.
