The group also visited the 3,300 acre Chesapeake Farms where they observed a wide variety of wintering waterfowl including tundra swans and many ducks including pintails, green-wing teals, shovelers and other species. The group saw lots of birds but some special ones were: the horned lark, snipes, horned grebes and lots of bald eagles.
