There are several birds in the recording. This observation is for what I believe are the swans.
Found inside our building’s basement caught in a cobweb. Only produced stridulation squeaks once put outside onto a log. Once on the log pile, it immediately began chewing on an edge where the bark had been lost of a portion of the log.
7:30 am in a small park in St Louis county. There were 4. Very playful and curious. I'm thinking they were mink. At least one had a white chin. They entered a pond at one point.
Photo taken at Mingo National Wildlife Refuge, where I needed a lot more zoom.
Example of some of leaves under it in pic of 📖 though many were oak leaves. Three tulip trees total in same area.
