Range. - Pacific coast of northern California, Oregon and Washington.
These diminutive little birds build nests that are marvels of architecture, making long purse-like structures, suspended from twigs usually at low elevations from the ground. The nests are made of moss, lichens, fibres, ferns and grasses and lined with feathers or wool; the opening is on one side near the top, and a typical nest averages 12 inches in length, by 4.5 inches in diameter at the bottom and 3 at the top. Their eggs number from four to nine and are pure white; size .54 x .40. The birds are very active and have the same habits as the Chickadees, being seen often suspended, head downward, from the ends of twigs, in their search for insects.
