During its migrations this tastefully marked Warbler is gone ‘ally uneommon 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-bi‘éasts so closely resemble the usually abundant young Black-polls that it: is sometimes ditlieult to determine specimens, while living birds could not possibly be distinguished.

In the summer the Bay-breasts inhabit the northern coniferous for- ests, living, it is said. in the tree tops. Mr. liangille 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 lse-c/me, tse-chee, tsu-c/we, ise-c/lee, tse-chcu, but. far too liquid to admit of exact spelling.”
