Just about everywhere you go here in western Arkansas and eastern Oklahoma this time of year, you will see a large flock of Red-winged Blackbirds.
A great place to see them is at the Sequoyah National Wildlife Refuge in Oklahoma. Some of the flocks are very large. Here are a few photos I took back in 2010 that will give you an idea of the size of these flocks: Where’s Waldo?
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. (All About Birds)
