BLACKBIRDS IN WINTER. — Since the flrst week in December there have 
been two, and part of the time three, Rusty Blackbirds constantly about 
one of my barns. At the same locality a number of Cow Blackbirds were 
seen last winter and the winter before. They appeared about the middle 
of November, and left the last of March. tae es only three or four 
were observed, but «the highest number seen was nineteen. They were 
usually very tame, allowing one to approach within eight or ten feet of 
them. Their only note was a sort of a whistle, uttered while sitting on the 
top of an apple-tree. The Cow Blackbirds were usually very active, but . 
the Rusty Blackbirds seemed much pinched with cold, and in cold days 
sat crouched down on their feet.—Rosert HOWELL, Nichols, Tioga 
County, N. Y., Jan. 11, 1870.
