MUSCICAPA FORFICATA. 
sionally on vegetable substances, as, on dissection, the 
stomach of our specimen was found to be filled with 
pokeberries, (. Phytolacca decandra, L.) 
Beyond these particulars we have no positive know- 
ledge of the manners of our flycatcher, though Vieillot 
has recorded a history of some length, taken from 
D’Azara ; but the bird observed by the latter author 
in Paraguay and Buenos Ayres, though closely allied, 
appears to be specifically distinct from the one we are 
describing. Vieillot has since been convinced of this 
difference, and, in the (French) New Dictionary of 
Natural History , he has separated the more southern 
species under the name of Tyrannus violentus . In 
colour that bird strongly resembles our Muscicapa 
savana , but it is considerably smaller, and has different 
habits, being gregarious ; whilst the savana is a solitary 
bird. 
Another species, for which ours may be readily 
mistaken, is the Tyrannus bellulus , Vieill. which, how- 
ever, is much larger, with a still longer tail, differing 
also by having a large black collar extending to each 
corner of the eye, margining the white throat ; and the 
head of the same bluish gray colour with the other 
superior parts of the body ; the remaining under parts 
being of the same colour, with a narrow brown line in 
the middle of each feather; and by having a whitish 
line on each side of the head behind the eye, extending 
to the occiput. The Tyrannus bellulus is a native of 
Brazil.

BONAPARTE, PLATE II. FIG. I. 
The plate given by Buffon of this rare and beautiful 
bird conveys but an imperfect idea of its character. 
That author had the merit of publishing the first account 
of the species ; and the individual he described was 
received from that part of Louisiana which borders on
