P.M.—Down river to Red Bridge.

  The blackbirds Dave a rich sprayey warble now, sitting on the top [of] a willow or in elm. They possess the river now, living back and forth across it . . .

  The blackbirds fly in flocks and sing in concert on the willows,—what a lively, chattering concert! a great deal of chattering with many liquid and rich warbling notes and clear whistles,—till now a hawk sails low, beating the bush: and they are silent or off, but soon begin again. Do any other birds sing in such deafening concert? . . .
