In Western Massachusetts, Mr. Allen states it to be common from the 15th to the 25th of May, and again in September. They were found by Mr. C. W. Bennett on Mount Holyoke during the breeding-season, and by Mr. B. Hosford on the western ridges during the same period. They are common, Mr. Boardman states, in the thick woods about Calais, through all the breeding-season. In Jamaica, during the winter, it exclusively frequents the edges of tall woods in unfrequented mountainous localities. They are found in that island from October 7 until the 9th of April. Mr. Gosse, who has closely observed their habits during winter, speaks of their playing together with much spirit for half an hour at a time, chasing each other swiftly round and round, occasionally dodging through the bushes, and uttering at intervals a pebbly _cheep_. They never remain long alighted, and are difficult to kill. Restlessness is their great characteristic. They often alight transversely on the long pendent vines or slender trees, hopping up and down without a moment’s intermission, pecking at insects. They are usually very plump and fat. De la Sagra states that this bird occasionally breeds in Cuba, young birds having been killed that had evidently been hatched there. The record of this Warbler, as presented by different authors, is apparently inconsistent and contradictory: rare with some observers, abundant with others; remaining in Jamaica until well into April, yet common in South Carolina in March, and even appearing in Massachusetts in midwinter; supposed to breed in the highlands of Cuba, yet, except in the case of the nest taken near Halifax, its manner of breeding was unknown until lately. It is probably rare in lowlands everywhere, and nowhere common except among mountains, and, while able to endure an inclement season where food is abundant, is influenced in its migratory movements by instinctive promptings to change its quarters entirely in reference to a supply of food, and not by the temperature merely. Its presence in Boston in winter was of course a singular accident; but its plump condition, and its contented stay so long as its supply of food was abundant, sufficiently attested its ability to endure severe weather for at least a limited period, and while its food was not wanting. Mr. Trippe states that these birds reach Northern New Jersey during the first week of May, and stay a whole month, remaining there longer than any other species. At first they have no note but a simple chirp; but, before they leave, the males are said to have a singular drawling song of four or five notes.
