Detalhes da observação
We counted the scaups using a scope set-up on the south side of the parking area under the bridge. The raft extended the entire length of Rte 125 toward the VFWD access downstream. Siler estimated 2000 birds and asked me to double-check. So I counted the raft edges by 10s, then the denser middle part of the raft by 100s. I counted more than 3000, but rounded down to be safe. When we left, we drove along Rte 125 and pulled over to confirm the ID from a shorter distance. Siler took a few pictures of the raft, which we included - the pictures don’t capture the whole raft though.
