The Red Run swallows
The underground StormWater retention basin tunnels of the Red Run
in Warren, Michigan are home to hundreds of American Cliff Swallows.
The Cliff Swallow is a member of the passerine bird family
Hirundinidae – Petrochelidon pyrrhonota.
American cliff swallows build their mud nests not only on cliffs,
but also on overhanging human-made structures, such as bridges/dams.
They like habitats with abundant insects and access to wet earth.
Swallows return to the same area each year to breed, hatch, and fledge,
(raise young until they can fly). As long as the nest holds up, it gets reused.
Building a mud nest may take anywhere from a week to a month,
with both male and female working together, using thousands of mud pellets
carried one by one in their bills. Straw and grass are also used,
and the nests are lined with feathers. The birds are colonial,
meaning that they often build nests in groups.
Video and pictures taken in early evening around 7:30pm

fly very, very quickly making photography a challenge !
