he saw of this bird, were obtained on the 22d of January 
at Ossabaw Island, when but a few males were seen 
scattered over the cotton plantations. Advancing* 
towards the south, they became more numerous ; and 
in the early part of February, the males, unaccompanied, 
by females, w r ere common near the mouth of the river 
St Juan in Florida. A few days after, the females 
appeared, and associated by themselves on the borders 
of fresh water ponds ; they were very gentle, and 
allowed themselves to be approached within a few feet, 
without becoming alarmed. Flocks composed of both 
sexes were seen about the middle of March. 
About the latter end of November, they leave even 
the warm region of Florida, to seek winter quarters 
farther south, probably in the West Indies. Previous 
to their departure, they assemble in very large flocks, 
and detachments are seen every morning moving south- 
ward, flying at a great height. The males appear to 
migrate later than the females, as not more than one 
female (easily distinguishable, even in the higher regions 
of the air, by its much smaller size) is observed for a 
hundred males, in the last flocks. 
The great crow blackbird is also very numerous in 
the West Indies, Mexico, and Louisiana ; but it does 
not frequent the Northern, or even the Middle States, 
like the common crow blackbird. Our opinion, that 
the Corvus Mexicanus of authors is the male of this 
species, and their Corvus zanoe the female, is corro- 
borated by the male and female great crow blackbird 
being seen in separate flocks.

The specific name of this bird (quiscala) has been 
changed, in consequence of its having been applied to 
the genus : we have substituted the name given by 
Vieillot, which is admirably appropriate. The English
