Continued . . .

A "hot spot" for bird watchers, uncommon species like Le Conte's sparrow, common moorhen, American avocet, marsh wren, sedge wren, and red-necked grebe are nesting on the refuge and are routinely seen.

In just the last three years, 13 previously unrecorded bird species have been confirmed as nesting on Hamden Slough refuge. These include: Virginia rail, dickcissel, semi-palmated sandpiper, American bittern, prairie chickens, Wilson's phalarope, and gadwall.

The refuge impoundments are managed in May and June for migrating and nesting shorebirds and waterfowl. This has resulted in an increased abundance of previously rare species such as godwits, dowitchers, dunlins, and many other "life list" species.

The numbers of public visitors surge in May and June, with many wildlife viewers checking Bisson Lake and the "frog pond," on the north end of the refuge, and the office wetland complex on the south end. Neotropical nesters and migrants are also most easily observed from mid-May through mid-June. The abundance of refuge wildlife attracts avian predators, including bald eagles, harriers, falcons, hawks, kestrels, and merlins.
