This species, like Grinnell's Water Thrush, inhabits the low 

 bottom, timbered lands bordering the edges of water, preferring 

 running streams; a shy, retiring bird, that runs for cov^er the 

 moment it sights an intruder, but is so restless that, if you will 

 stand motionless, it will reappear in a short time and continue 

 its rambles in quest of food, chiefly insect life, minute snails, 

 etc, and in search for the same will often wade until its body 

 touches the water. Its motions are peculiar: a continued tilting 

 of the body and jerking of the tail. Its flights are easy and 

 direct, but low, and usually short. It is one of our earliest and 

 sweetest songsters; sings from the perch, with tremulous wings 

 and inflated throat, a rich and almost unrivaled song of power 

 and melody. Its ordinary note, a sharp "Chip," is often heard. 



Their nests are placed on the ground, under projecting roots, 

 old logs and fissures in rocks, on the banks of streams and ponds, 

 and near the water's edge. They are composed of leaves and 

 mosses, and lined with fine grasses, fibers and hairs; the foun- 

 dation is wholly of leaves, with mud generally between the lay- 

 ers to hold them in place. Eggs three to six — usually four or 

 five, .76x. 59 (they vary in size); white to creamy white, spot- 

 ted with varying shades of reddish brown, and shell stains of 

 lilac gray, usually thickest about the larger end; in form, oval 

 to rounded oval.
