Day of R. Ostrofa Byanta canadensis - flock of 4 mis. Camb. 281 Carpodacus purpureus - male singing-Camb. MASS. (Middlsex Co.) Passer domesticus - building Camb. 1876. (March 28.) Pickets which the birds had dropped. Among the pines I noticed a little flock of Bugulus ostrofa, the males singing at frequent intervals pretty as in Me. This song is rather pretty, and commences like D. lugina's ends about H. sufficilla's. Starting homeward we reached Watertown late in the afternoo. On the road back I shot two Bobolink and Hayes a Crow. We also saw four Byanta canadensis flying in high flew toward the N. The leading bird was noticeably much larger than the following ones of which the last was the smallest Wednesday March 29 Clear and warm. Ths. 60° max. temp. Spent the day in town but made two observations worth recording before going in; on, a purple finch in full song in Mr. Choates Garden the other, a large flock of Byanta Canadensis which attracted my attention by their gabbling as they drifted high overhead before a strong S. wind. Both yesterday and to day a large flock of Blackbird (C. purpureus & Angelinus) have haunted our field spending most of their time on the ground but occasionally mounting to the tree tops and setting up their discordant Chorus. Passer domesticus is everywhere engaged in nest building and the males are now if possible more noisy and offensively disagreeable than usual.
