Redheads spend their winters in large mixed flocks on the Gulf Coast and sometimes in the Great Lakes. These gregarious, social ducks can be found huddled with other ducks and waterfowl in flocks up to 60,000 on large bodies of water during winter.

Garganey at Zeloski Marsh

"A Garganey observed last week at Zeloski Marsh is only the second individual reported in Wisconsin history. This bird is a twitcher’s dream. Is it rare? Yup. Did someone provide decent directions? You bet. Does it have a unique look? Yes. Easy to get to? Mhmm."

Lesser Scaup

Looking into research on Lesser Scaup, I came across numerous articles about diet, lipid stores, and reproductive output. All highly cited, and most published within the last twenty years. As it turns out, Scaup remain a bit of a mystery, despite all of this research.
