Purple martin, June 22, 2019, Blenheim Ontario.

Progne subis
Purple Martins roost together by the thousands in late summer, as soon as the chicks leave the nest. They form such dense gatherings that you can easily see them on weather radar. It’s particularly noticeable in the early morning as the birds leave their roosts for the day, and looks like an expanding donut on the radar map.
