I know there's a cardinal here but there's another call I don't recognize a couple of times, there's one at around 13.2 seconds in the recording.
Mottled mix? domestic Mallard/Mexican mix? The jury’s still out but it’s highly unlikely to be a pure Mexican Duck is the feedback I’m getting.
Great find anywhere in PA; on our beach at Beltzville State Park this morning. Reported on eBird, as well.
