The female differs from the male in having the bcW 
and vent rufous white, instead of light chestnut; thei^ 
parts are also slightly clouded with rufous; and tk' 
exterior tail-feathers are shorter. 
These birds are easily tamed, and soon become ek' 
ceedingly gentle and familiar. I have frequently k<f' 
them in my room for several days at a time, where th«f 
employed themselves in catching flies, picking thf*'' 
from my clothes, hair, &c. calling out occasionally 
they observed some of their old companions passing tk'* 
windows.

OKEEN, SLUE, OR WHITE BELLIED SWALLOW, WILSON. 
WILSON, PLATE XXXVIII. FIG. III. 
This is the species hitherto supposed by Europei>** 
to be the same with their common martin, hirvtA 
wrbica, a bird no where to be found within the Unit‘’“ 
States. The English martin is blue black above ; 
present species greenish blue ; the former has the whf J 
rump white, and the legs and feet are covered t'i'j 
short white downy feathers ; the latter has nothin? ,
