Scientific classification of birds. — Modern scientific classi- fication divides the birds of North America into seventeen groups or. Fig. 60.—Blue heron. (Wright's " Citizen ;) orders, all the birds of a given order resembling each other more or less in structure. The common names given to some of these orders are suggested by their habits. As examples we may name divifig birds (loon), long^winged swimmers (gulls and terns), scratching birds (hens, turkeys, and quails), birds of prey (eagles, hawks, and owls), and woodpeckers (downy woodpecker). The highest order, known as birds, is divided into twenty families, some of which are the crow family, the sparrow family, the warbler, and the.
