Though Brisson, Linne, and Pennant, have stated the fork- 
tailed flycatcher to inhabit this region, as far north as Ca-

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 deci- 
dedly marked habits, and will most probably be found entirely restricted to the 
northern parts of the south continent, and extending slightly, and in small num- 
bers, into the north. 
The peculiar form of the tail, and the extreme developement of the organs of 
flight, induced Mr Swainson to use these birds as typical of a section among the 
tyrants, to which he has given the characters of, “ Alee longce nmigiirn pogoniis
