The species of the Of d World which, though commonly called "grosbeaks," certainly belong to the family Ploceidae, are treated under WEAVER-BIRD.
Amongst the Passeres, such forms as the larks, stone-chats, finches, linnets and grosbeaks are well developed, and exhibit many species.
His colleague, Vieillot, brought out in 1805 a Histoire naturelle des plus beaux chanteurs de la Zone Torride with figures by Langlois of tropical finches, grosbeaks, buntings and other hard-billed birds; and in 1807 two volumes of a Histoire' naturelle des oiseaux de l'Amenique septentrionale, without, however, paying much attention to the limits commonly assigned by geographers to' that part of the world.
The birds of this genus - the crossbills - when their other characters are taken into account, prove to be intimately allied on the one hand to the grosbeaks (Pinicola) and on the other through the redpolls (Aegiothus) to the linnets (Linota) - if indeed these two can be properly separated.
The mountain-finches may be regarded as pointing first to the rock-sparrows (Petronia) and then to the true sparrows (Passer); while the grosbeaks pass into many varied forms and throw out a very well marked form - the bullfinches (Pyrrhula).
