Chrysomitis pinus Dec. 16 — 1874 Dec. 16 Clear and rather mild. In P.M., took a turn up on the farm and much to my surprise struck a large flock of C. pinus in the cedar grove. Then saw some thirty in all and they were feeding on the seeds of the Cedar berries. This is the first time that I ever found the bird here in winter. Killed 8 in 4 shots and on dissection found that it was impossible to distinguish the sexes by plumage at this season, although adults were quite readily to be separated from birds of the year. They were very tame, in fact could not be driven away from the spot & I could have rounded the whole flock. Among them was a very bright adult & Carpodacus purpureus (four individuals of which I forgot to write on the 10th inst). Saw also a fine male of Argyrotes linaria & a small flock of Pirieola behind Mt. Auburn. Heard an immature bird of this latter species trying apparently to sing and he really produced fine fin notes all of which reminded me much of those of C. purpureus. Saw a first junco a single Gardening, (doubtless the identical bird found in the same place on the 10th) and at least 30 Regulua latrapa in one flock. This species literally swarms here this winter. While standing in a grove of pines my attention was attracted by a whistling overhead and looking up I discerned a Bluebird And. flying high up in air towards the North.
