PASSERINiE. 
181 
The Tyrants {Tyrannus, Cuv.) — 
Have a long, straight, and very stout bill ; the ridge of the upper mandible straight and blunt ; its 
point abruptly hooked. They are American birds, of the size of our Shrikes and equally spirited, 
which defend their young even against Eagles, and drive all Birds of prey from the vicinity of their 
nest. The largest species prey on smaller birds, and do not always disdain those they find dead. 
[They have even been observed to plunge after fish in the manner of a Kingfisher; and have been 
sometimes noticed to throw up their food and catch it in the throat, as in the Toucans, Hornhills, &c. 
The species are extremely numerous, and have been further subdivided by different systematists. Thus, several 
with extremely furcate tails compose the Milvulus, Swains,, and the smaller and weaker species the Tyrannula of 
the same nomenclator : the latter grade into the Kinglets. Others constitute the Platyrynchus, Vieillot, &c. The 
majority have yellow or red coronal feathers, somewhat as in the Kinglets.] 
The Moucherolles {Muscipeta, Cuv.) — 
Have a long beak, very much depressed, and twice as broad as high, even at the base ; the ridge of the 
upper mandible very obtuse, but sometimes however the reverse ; the edges slightly curved, the points 
and emargination feeble, and long vibrissse at the gape. 
Their weakness disables them from preying on aught but insects. All of them are foreign ; and 
many are ornamented with long tail-feathers or with fine crests, or at least have vivid colours on the 
plumage. 
[Se\'eral different natural groups are here brought together: the term is now generally restricted to some beau- 
tiful birds of the eastern hemisphere, the males of which have crimson and black plumage, and long even tails, the 
females being yellow where the male is red ; their colours are distributed as in the Redstarts, and there are other 
birds of similar form and colouring, but stouter and larger, which compose the PJuenicornis, Gould.] 
Some species approximating the Moucherolles [or rather the Tyrants], — 
The Flatbills {Platyrynchus, Vieillot), — 
Are remarkable for having the bill still broader and more depressed. 
[They have been confused by many writers with the Todies, a wddely separated genus, that does not even possess 
the distinctive characters of the Passerince. They have also been ranged under many named minor subdivisions.] 
Others, which have also the beak broad and depressed, are distinguished by their longer legs and 
short tail. They compose the genus 
Conopophaga, Vieillot, — 
Of which but two or three species are known, all from America, that subsist on Ants, which has cfmsed 
them to be ranged with the small tribe of Thrushes termed Antcatchers. 
The Restricted Flycatchers {Muscicapa, Cuv.) — 
Have shorter bristles at the gape, and the bill more slender than in the Moucherolles. It is still, 
however, depressed, with an acute ridge above, a straight edge, and the point a little curved downward. 
[They are closely related by affinity to the Chats and Redstarts, as are also the Moucherolles, and have 
similar mottled nestling plumage, a character that does not occur in the great Tyrant group. 
Four species inhabit Europe, migrating southward in winter.] 
The Grey Flycatcher (if/, grisola, Gm.)— Grey above, whitish underneath, with some greyish streaks on the 
breast. [It is very common throughout Britain, seldom arriving before May : one of the least musical of our 
native Birds. Its legs are shorter than in the following, and general character different : hence, with some others 
from Africa, it composes the But alls of Boie.] 
The Collared Flycatcher {M. albicolUs, Tern.), is very remarkable for the changes of plumage [or rather of 
colouring only] which the male undergoes seasonally. Resembling the other sex in winter, that is to say, grey [on 
the upper parts] with a white patch on the wing, it attains towards the nuptial season an agreeable distribution of 
pure black and white, the head, back, wings and tail, being of the former colour, and the forehead, a collar round 
the neck, a great patch on each wing, a smaller one in front of it, and the outer edge of the tail, white. It nestles 
in the trunks of trees. 
Another species subject to the same changes has more recently been discovered, in which the neck of the male 
is black like the back in the nuptial season, and which wants the small white spot on the edge of the wing. It is 
the Pied Flycatcher (M. luctuosa, Tern.), which is found further northward than the other. [This species is 
remarkable for its local distribution in the British islands, being very common near the lakes of the north of 
England, and of rare occurrence elsewhere. It is doubtful whether the other ever occurs here. They are said to 
differ in their notes, and both lay blue eggs, whereas the Grey Flycatcher lays whitish eggs spotted with brown. 
The two pied species are also comparatively musical.]
