Dr. Ridgway says of the Palm Warbler, “During the spring migration this is one of the most abundant of the warblers,” in Illinois, “and for a brief season may be seen along the fences, or the borders of fields, usually near the ground, walking in a graceful, gliding manner, the body tilting and the tail oscillating at each step. For this reason it is sometimes, and not inappropriately called Wag-Tail Warbler.” The observer is reminded of the titlarks as he watches the nervous activity of this Warbler as it constantly jerks its tail while it flutters about the hedges and scattered shrubbery, or when running on the ground among the weeds of old fields. It may even frequent dusty roadsides. Wherever it is, it frequently utters its low “tsip,” a note that is very similar to that of many of its sister warblers. Dr. Brewer says, “They have no other song than a few simple and feeble notes, so thin and weak that they might almost be mistaken for the sound made by the common grasshopper.” The Palm Warbler’s nest is a trim structure, usually placed upon the ground and never far above it. The walls consist of interwoven dry grasses, stems of the smaller herbaceous plants, bark fibres and various mosses. It is lined with very fine grasses, vegetable down and feathers. Though this home is placed in quite open places, a retired spot is usually selected. Here are laid the white or buffy white eggs, more or less distinctly marked with a brownish color, and a family of four or five of these peculiar Warblers is raised. [Illustration: PALM WARBLER.
