October 27, 2010, Steve Pink and I visited the Westport area, hoping to see Red Phalaropes, and other birds that the recent storm may have blown in.
We found about 40 phalaropes in a pond adjacent to Westhaven State Park. I looked carefully to see if the group included any Red-necked Phalaropes. Didn't see any. But while cropping, enlarging, etc, the digital images I took that day, I noticed that at least 2 of the birds were red-necked.
One photo includes both species. The Red Phalarope has a heavier and shorter bill. The underwing of the red is much whiter than that of the red-necked. Plumage differences are subtle.
