in many cases it is impossible to say to which birds certain records apply. Doubtless there is little ditferenee in their notes or habits, but our knowledge, of u/[eite in its summer home is too limited for us to say much about it (see, however, Nelson, Rep. on Nat. Hist. Collec- tions made in Alaska, 1). 216).

757a. T. a. bicknelli Ii‘iilgw. BIUKNEI.I.‘S 'I‘imrsn.—Similar to the preeeding. but averaging somewhat brighter and constantly smaller. L., 02577-25; W., awe-so; T.. 21507270; 13., ‘50-'52 (Ridgox).

flange—Breeds in the higher parts ot' the Catskills and northward to the White Mountains and Nova Scotia; winters in the tropics.

Washington, apparently rare T. V., two instances, May. Cambridge, rather common T. V., May 15 to May 25; Sept. ‘2') to Oct. 6.

Next, essentially like that of T. szl'aiusrmii, both in construction and posi— tion. 1110,48, «greener and more finely spotted than those ot‘xwainaonii (Brew— ster, Minot‘s Land Birds and Game Birds, Ltd ed., appendix, p. 465).

“In northern New England Bicknell‘s Thrush breeds from an alti- tude of about three thousand feet (scattered pairs may be found lower than this) to the extreme upper limits of tree growth, but most abun- dantly among the dwarfed, densely matted spruces and balsams which cover such extensive areas on the upper slopes and ridges of our higher mountains. Here, in an atmosphere always cool and ordinarily satu- rated with moisture from passing clouds, it spends the summer in company with such birds as Swainson’s 'l'hrushes, “'inter Wrens, Yellow-rumped and Black-poll Warblers. Juneos, “’hite—throated Sparrows, and Yellow—bellied Flycatchers. In many places it is quite as numerous as any of these species, and in certain favored localities it probably outnumbers them all put together. Nevertheless one may spend hours in its chosen haunts without getting a fair view of a sin- gle individual, for, despite (or perhaps really because of) the fact that these solitudes are rarely invaded by man, liieknell's Thrush is, while breeding, one of the very sliyest of our smaller birds. . . .

“ The song is exceedingly like that of the Veery. having the same ringing, flutelike quality; but it is more interrupted, and it ends dif- ferently,—the next to the last note dropping a half tone, and the final one rising abruptly and having,r a sharp emphasis. The ordinary calls are a wliistled plieu practically identical with that of T. fumes-ems. a harsh note which recalls the cry of the Night Hawk, a low eluek much like that of the Hermit 'l‘hrush, and a [zip or permit similar to that of Swainson‘s Thrush. The last is rarely heard ” (Brewster, l. c., p. 467).
