Has anyone else noticed all the birds under the Market Street Bridge? If you’ve been to Coolidge Park recently, you may have seen a lot of small birds flying in and out of mud nests built underneath the bridge.

We wanted to know what kind of birds they are and why there are so many of them — specifically under the bridge — so we consulted a local bird expert + checked via a bird identification app and both sources tell us these are most likely cliff swallows.
