AVES. 



The Restricted Barbets {Bucco, Cuy.) — 

 Have the lieak dimply conical, slightly compressed, with a blunt ridge, a little raised ahoiU t)ic middle. 

 They are found in lioth continents, and arc generally adiinird \\'\X\\ vivid cidoiu'^i. At the season 'jT 

 propagation thc\' arc found in jiairs, and in little triKips [ijr faniilies] during the remainder of tlie year.

 the AVoodpi'ekers : the tun^^^ue, liuwever, is of the Oi'diuiuy struetuie, and tliey have hut ten tail-lVatliers, \\hicli 

 iire not rigid. Their feet also are adapted for descending the trunks of trees, hke a Nuthatch, and not merely for 

 ascpudinsrtheni, as in the Woodpeckers and Tree-creepi.Ts ; havin^^ the cla'w of the reversed toe particularly hooked 

 and sliarp. The beak is especially fitted for cuttinu- ilir strms rif iVuit;?, as with a pair of scissors ; and they lay 

 always tour white eggs in the holes of trees, uccasinii;illy i-ooitin-; In the composite nests of the social Grosbeaks. 

 Some other divisions have been instituted among them, \vith propriety; and they altogether constitute a natural 

 laniily, some species of which aie even entiiely destitute of the tufts of bristles, which latter may be traced, in 

 various degrees of developement, in nian\' I'lther birds, ;is the Trogons, S:c.]

[They are generally subdivided into Tnma/ia proper, the beak of which somewhat approximates that of the 

 Bush-shrikes, and Lt/porni/x, in which it is smaller, little if at all hooked at the tip, and grading towards tiiat of the 

 Barbacous. Togetlier with the latter genus, and the Courols of Madagascar, they form a distinct gfroup, most 

 nearly related to the Cuckoos, which they resemble anatomically; all the members of which appear to possess the 

 habit of puffing out their feathers, and perch lengthwdse, clasping the bough with theii- first nud fourtli toes, which 

 are directed sideways and not backw^ards, the same as in the Touracos ; they h;i\e iiil tui^U e tail-feathers and 

 uivariably lay two eggs, in hoh'S either of trees or banks, which probai.)l\ iiniduri.- uiaic jind tVinale that associate 

 for life, as they are constantly observed in pairs. Tlie American species apjiear to diller in being exclusivelv 

 insectivorous, watching for the larger insects, which they take in the manner of a Flycatcher : their manners are 

 familiar; and the plumage of the forehead directed forwards and more or Irs.s t(_Tmiiiatini.^ in stilf jiuints, very 

 rigid to the feel, which admirably defend the eyes from the lUittcring of thrir iusect-jirry. Thi_- culnurs nf all are 

 tombre, and not gay, as in the Barbets]. 



The Trogoxs {Trogou, Lin.) — 

 Together \vitb tlic bmidles of bristles round the bill of the Barbets, have a short beak, broader than 

 nigh, (■iir\ed at its base, with a blunt arcuated ridge to the upper mainliblc. Their small feet, feathered 

 nearly to the tors, dieir long and broad tail, and fine, light and dense ].bimage, iin]Mrt a peculiar air. 

 Some poniou of (heir plumage has generally a brilHant metallic lustre ; the rest luMiig vivid]}' coloured. 

 They nestle in tlie holes of trees [producing two nr four deli.'afe rounded white ciig^, the shell of which 

 is particularly slight and fragile], subsist on insects, and frequent low branches in the interior of thn;k 

 woods, flying only during the morning and evening. 



[The Trogons constitute another distinct and insn- 

 lated group, intermediate in some respects to the 

 Cuckoos and Moth-hunters, both which they resemble 

 generally in their anatomy, but are hatched naked, in 

 which they differ from either. The sternum (fig. 102) io 

 doubly emarginated. Their toes are rennukable for 

 being zygodactyle on a different principle from that of 

 any othrr LiTinis ; the ordinary inner toe being reversed 

 instead (if Mir ninrr one : their feathers closely resemble 

 in strurtnre those of the true PoultiT, and are similarly 

 elongated over the rump, where in certain species they 

 attain nn extraordinary developement in the male sex, 

 analogous to the train of a Peacock. Like the Foultr>-, 

 also, they are remarkable for the small proportional size 

 of the head. They capture insects in the manner of a 

 Fly-catcher, with a swift and deeply undulating flight , 

 some of them feeding likewise upon berries. Are found 

 in the warm regions of both continents.]
