`We saw this very large moth at the start of our Mill Creek Marsh Walk yesterday — and likely misidentified as a Sphinx Moth.

Upon further review, going with Underwing Moth — not sure which but possibly a Mourning Underwing. (We had a similar one at the MEC last September; link is here.)

More on Underwings here.

We’ll post the full list of birds seen on Sunday’s Mill Creek Marsh walk tomorrow.
