Rusty Blackbird Behavior
True Life Rusty Blackbird Behavior
Here is one of several instances of behavior as found on the Birdzilla site. This particular story was from a 1928 letter.
Behavior: Mr. Skinner (1928) writes:
Rusty Blackbirds on the ground walk, and run nimbly, with a nodding of their heads forward and backward in time to their own steps. As compared with other blackbirds, this species is perhaps tamer and certainly more quiet, composed and dignified. When hunting across the ground, members of the flock are continually walking and running, and frequently individual birds fly a few feet to a position at the front.
While Rusty Blackbirds fly in dense compact flocks all winter, and appear to enjoy the society of other members of their own kind, they are less apt to join other species. When in flocks composed of several species, the Rusty Blackbirds usually split off into separate flocks composed of their own kind. But at times they vary this and join flocks of Meadowlarks and Starlings; but on the other hand Starlings, Cowbirds and Red-winged Blackbirds more often join the Rusty Blackbirds. During the winter these Blackbirds are also seen temporarily with Bluebirds, Juncos, Doves and Horned Larks.
While the flocks of Rusty Blackbirds are more dense and compact than most other species, they are not so much so as those of Red-winged Blackbirds. A flock in flight moves steadily onward, but the individual birds undulate up and down, or swing from side to side, so that the relative positions constantly change and give the flock a rippling appearance. They fly either against the wind or with it. In the latter case, just before alighting on ground or trees they wheel and come up to their perches against the wind. In its minor points, the flight of these birds is thrush-like. Rusty Blackbirds are quiet during the winter, but the song also suggests a thrush rather than a blackbird.
