what local, being extremely common in some places and entirely absent 
in others. I have generally found it in large flocks flying about with great 
speed and frequently resting on the branches of dead trees. It makes a 
remarkably tiny nest of bits of bark and feathers glued together with 
saliva, and placed on the side of a horizontal branch. The nest is so 
minute, that when the bird is sitting it cannot be seen, and the bird 
appears to be merely perching on the branch. Only one egg is laid, and it 
is white. The breeding-season in Burmah is probably from April to June.

Description. — Male. Forehead, crown and upper wing-coverts metallic 
green, each feather more or less edged with deep blue ; nape, sides of the 
neck, scapulars and the back metallic green, each feather obsoletely 
margined with blue; rump, the shorter upper tail-coverts and the tips of 
the scapulars grey ; the longer upper tail-coverts greenish brown ; lores 
and cheeks black ; ear-coverts chestnut ; chin, throat, breast, upper 
abdomen and sides of the body grey, rather darker than the rump ; lower 
abdomen, vent and under tail-coverts white ; quills brown, suffused with 
blue ; the tertiaries whitish ; tail greenish at the base, blue elsewhere. 
Specimens vary much in the amount of blue on the head and wings ; in 
some the blue is entirely absent. The tail and wings also vary; in some 
green predominates, in others blue. 
The female differs in having the ear-coverts not chestnut, but a greenish 
brown. 
The young appear to have the greater part of the upper plumage tipped 
with white. 
Length 9 inches, tail 4*5, wing 6*5, tarsus '4, bill from gape '7. The 
female appears to be of the same size. 
The Malayan Crested Tree-Swift occurs in Tenasserim from the 
southernmost point up to Mergui and Nwalabo mountain. 
It extends down the Malay peninsula, and is found in the islands of 
Sumatra, Java, Bangka and Borneo. 
This species is an inhabitant of the forests. Like the preceding, it
