of grasses and plant fibers, lined with plant down and long hairs, in coniferous trees, five to twenty feet up. Eggs, four to five, white, finely WOOD WARBLERS. marked, chiefly at the larger end, distinctly and obscurely with cinnamon-, olive-, or rufous-brown, 72 x 52.
During its migrations this tastefully marked Warbler is generally uncommon enough to be considered somewhat of a prize, though at irregular intervals it becomes comparatively common. It is said to be much rarer in fall than in spring, but the immature Bay-breasts so closely resemble the usually abundant young Black-polls that it is sometimes difficult to determine specimens, while living birds could not possibly be distinguished.
In the summer the Bay-breasts inhabit the northern coniferous forests, living, it is said, in the tree tops. Mr. Langille writes: "Their song, said to begin like that of the Black-poll and end like that of the Redstart, bears to my ear no resemblance whatever to either, but is a very soft warble, somewhat resembling the syllables tse-chee, tse-chee, tse-chee, tse-chee, tse-chee, but far too liquid to admit of exact spelling." 661.
