THoucH Brisson, Linné, and Pennant have stated the fork- 
tailed flycatcher to inhabit this region as far north as Canada, 
* The latter part of the description of this bird will show that more 
than one species has been confounded with it ; and I am not sure that 
those very closely allied are yet properly unravelled, The present 
species has more decidedly marked habits, and will most probably be 
found entirely restricted to the northern parts of the south continent, 
and extending slightly, and in small numbers, into the north. 
The peculiar form of the tail, and the extreme development of the 
organs of flight, induced Mr Swainson to use these birds as typical of
