This morning around 8:15am I re-found the Lucy's Warbler discovered by Sarah Ngo yesterday at North Weddington Rec Center Park. It was in the same general location as reported on eBird - on the NW side of the park, in a weedy area just on the other side of the chain link fence between the park and the river channel. The bird was with a flock of Lesser Goldfinches feeding quite loudly; there was also a bunch of Bushtits, 2 Orange-crowned Warblers and some Chipping & White-crowned Sparrows feeding on the same plants. If spooked, most of the birds (Lucy's included) will fly across the river channel to the trees around the homeless encampment or up into the trees on the park side of the fence - but they will return to their dandelion patch eventually.
The park is super busy on the weekends between 9:30-4ish, as Kimball reported in his email yesterday, so be warned! It's also pretty busy after school gets out during the week (but if you are birding with kids in tow, they will at least be entertained!)
Some not-very-good photos are in my eBird list:
