“Red-winged Blackbirds roost in flocks in all months of the year.
In summer small numbers roost in the wetlands where the birds breed.
Winter flocks can be congregations of several million birds,
including other blackbird species and starlings.
Each morning the roosts spread out, traveling as far as 50 miles to feed,
then re-forming at night.”
