Yellow Warbler
652. Dendroica æstiva. 4 inches.
Range.—The whole of North America, breeding throughout its range. They are active little bunches of yellow, as they gather in their many insects for food, all the while singing their happy song. They place their nests in almost any kind of trees, but seem to prefer willows and alders near some brook or pond, where insect life is abundant. Their nest is a compact, cup-shaped structure, made of fibers and grasses, lined with plant down or cotton.
