In case anyone plans on searching for the Palm Warbler at Last Chance, you may want to make sure I didn't misidentify it. The yellow undertail coverts, eyeline, eyebrow, and the constant tail pumping are what sold me. However, here is a very poor quality image (rain, overcast, distant) of the bird in question. Feel free to decide for yourself. The bird was there between 0715 - 0730 in the morning and I never saw it again, despite two additional trips back to that area.
Hopefully, at some point tonight I may have some pictures of the two plovers and the two phalaropes (wilson's and red-necked) out past Anton.
