I looked for the Yellow-Throated Warbler first thing this morning and then again at around 7:30, with no luck. It could still be around if someone with more patience wants to give it a shot! I only spent about 30 minutes total looking around the spot.
The rest of the open space was very lovely, with at least one first of the season Least Flycatcher, a tree full of FOS Cedar Waxwings, and an Eastern Phoebe near the culvert by the beaver dam. Overall some really excellent habitats, I definitely plan to return. - Evan > On May 5, 2022, at 11:36 AM, Wayne Wathen <[email protected]> wrote: > > > Thanks for the information, Jared.
