PASSERINiE. 18] 



The Tyrants {Tijraiinus, Ciiv.) — 

 Have a long, straight, and very stout liiU ; tlie ridge of the upper mandiljle straight and blunt; its 

 ])oint ahruptly hooked. They are American hirds, of the size of our Shrikes and equally spirited, 

 wliich defend their young even against Eagles, and drive all Birds of prey from the vicinity of tlieir 

 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, Hornbills, &c. 



The species are extremely numerous, and have been further subdivided by dift'erent systeniatists. Thus, several 

 with extremely furcate tails compose the MUmlus, Swains., and the smaller and weaker species the Tj/raiinula of 

 the same nomenclator : the latter grade into the Kinglets. Others constitute the Platijrynchus, Vieillot, &c. The 

 majority have yellow or red coronal feathers, somewhat as in the Kinglets.] 



The Moucherolles {Muiicipe/a, 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 sbghtly cui-ved, the points 

 and emargination feeble, and long vibrissa; 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 

 pluniage. 



[Several 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 Phcenicornis, Gould.] 



Some species appro.ximating 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 widely separated genus, that does not even possess 

 the distinctive characters of the Passerbi<e. 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 tad. They compose the genus 



CoNOPOPHAGA, Vieillot, — 



Of which but two or three species are known, all from America, that subsist on Ants, which has canised 

 them to be ranged with the small tribe of Thrushes termed Antcatchers. 



The Restricted Flycatchers {Micscicapo, Cuv.) — ■ 

 Have shorter bristles at the gape, and the hill more slender than in the Moucherolles. It is still, 

 hov\'ever, depressed, with an acute ridge aliove, a straigld 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.] 



Tlie Grey Flycatcher (31. ffriso/a, 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 nnisical of our 

 native Birds. Its legs are .shorter than in the foUowing, and general character different; hence, with some others 

 from Africa, it composes the BidaUs of Boie.] 



The Collared Flycatcher (M. allAcolIis, Tem.), is veiy remarkable for the changes of plumage [or rather of 

 colouring only] which the male undergoes seasonally. ResemblinK 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 

 ]iure black and white, the head, back, wings and tail, beins of the foi-mer 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 (.V. lucliiosa, Tem.), 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 

 fhigland, and of rare occurrence elsewhere. It is doubtful whether the other ever occurs here. Tliey are said to 

 (lilVer 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.]
