Trativ’s Frycatrcner. 126. Arkansas Flycatcher. Inhabits western North America. This bird replaces our King Bird in the weet. They lay in May in California. The | nest is built on the low branch of an oak, | or any situation that excites their fancy. It is constructed of twigs, lichens, coarse ' grass, wool, etc., and lined with hair. The eggs, 4 or 5, are of a creamy white ground color, spotted with brownish and purple of two shades, and are oblong, though quite pointed at the smaller end. They measure 1 by .70 of an inch. The birds are quite easily tamed if taken when young, and make very interesting pets. 127. Cassin’s Flycatcher. Inhabits the valley of the Gila river and soutiern California. This bird is abundant in Vera Cruz, where it is called the Portuguez. They were found breeding at San Diego as euar- ly as the 28th of March. Nest larger and more firmly built than those of other mem- bers of this family, and measure from 5} inehes in external diameter to 24 in height ; cavity three inches wide attherim, Eggs | white, with a slight tinge of cream, cover- ed with large and scattered blotches of red- dish-brown. Size .96 by .70 of an inch. The nests vary much ; each locality literal- \ly having its kind of nest: that is, they are built with materials common to the locality, which locality differs considerably in productions from other localities. The size of markings also, widely differ. Our illustration is considered as the type | of their eggs; other sizes are men- tioned. A sect of two eggs taken in June, 74 THE OOLOGIST. 1863, by Mr. Jno.
