When black birds fly south

Now that breeding season is over for Red-winged Blackbirds, they will begin to gather in flocks of all male or all female birds. Northern populations migrate south to the southern United States and Central America beginning as early as August. Even though we’ve had no break in the weather, many birds are feeling a sudden restlessness as they prepare to move south.  Red-wings eat mainly insects in the summer and seeds found in fields or feeders, in the winter. In preparation for migration they may stop at your feeders for a last bite.
