At the end of the day today (9 May 2014), I made a brief stop and spotted three phalaropes feeding along the sandy banks of the creek.
In phalaropes, there is reverse sexual dimorphism — the males and females are distinct, but the females are slightly larger and are more colorful than the males.
Although I don't have a lot of practice separating male and female phalaropes, I'm pretty sure this is a male and female (below). The female is in the background, with a more distinct white eye-spot. The male is in the foreground; his eye-spot connects to the red neck patch.
Here's one more picture of the male for comparison:
Somewhat surprisingly, I posted a little more information about Red-necked Phalaropes on this same date in 2012. To read that post, click here.
