A couple more new ducks flew into the backyard pond last night. The five on the left are Lesser Scaups. Whatbird.com says that at one time these ducks were one of the most abundant and widespread of the diving ducks in North America.

The little guy on the right is a Ruddy Duck. These are considered an invasive species in Great Britain according to whatbird.com.
