PLATE LIIl.—YELLOW RED-POLL WARBLER. PALM WARBLER. 
Dendroica palmarum. 
Above brownish-olive, rump yellowish-green: crown dark bay ; 
beneath yellow, streaked on the breast with bay ; a bright yellow streak 
over, and a brownish line through the eye; the two outer tail-feathers 
tipped with square white spots; no white wing-bars. Length, 5.40 
Inches. 
Migratory. One of the earliest of the Warblers to come, and one of the latest to go. 
Its times of migration are late in April northward, and late in September or early in 
October southward. We see it here only as it passes. It generally keeps to fields and 
road-sides, and is oftener seen hopping upon the ground and flitting among bushes than in 
more elevated situations. Dr. Mearns thus points out one of its notable habits ; ‘The 
Red-poll’s tail executes a perpetual lateral vibratory movement, which is as characteristic 
as is the tilting of the Wagtails ; this motion is often accompanied by a feeble chip, the 
only note I have heard it utter,”
