I saw this duck at Round Pond in the Hawkeye Wildlife Refuge in Johnson County today. Any suggestions on ID for the one on the right? It was hanging out with Blue-winged Teal.
There was a nice selection of shorebirds including Dunlin, Semipalmated Plover, White-rumped, semipalmated, Least and Spotted sandpipers and Yellow legs. The activity was mostly in the southwest corner of the pond with nothing happening in the northern half.
