Genus DRYONASTES

The genus Dryonastes, of which D, ruficollis is the type, contains those Laughing-Thrushes which have the nostrils almost completely hidden by bristles, and in many respects show a similarity to the Corvidae, from which, however, in others they are as widely divided as they are in their habits and nidification.
They are all noisy, gregarious birds, feeding principally on the ground but also on bushes, and they eat both insects, seeds and fruit.
Harington proposed to divide the birds of this genus into two genera on account of the varying degree of density in the plumes, and bristles at the base of the bill and by the differences in the* shape of the bill itself. To be consistent, however, one would have to make yet further genera, for if ruficollis differs in degree from caerulatus, so also galbanus differs to an equal extent from ruficollis. Under the circumstances it would seem wiser to keep them together, and this I do.
