I’ve never seen these birds before March 15th 2012 when I spotted a few swimming in Chickamauga Lake. I startled them as I approached and they flew away. I manged to get a few pictures of their gat-a-way.
It took me a little while to figure out what they are. I finally decided that they are Lesser Scaup. They could be Greater Scaup but they are pretty small so I figured they must be the “lesser” variety.
