On Wednesday, John Holden and I were lured to the 180th Street Marsh in nearby Dakota County. We were disappointed in the lack of diversity we discovered. But we enjoyed the few birds we did see, like this adult Pied-billed Grebe.
Pied-billed Grebes are opportunistic feeders. They prefer crayfish, but also consume other invertebrates, frogs, and fish. Most of this prey is taken by diving. Dives last about 12 seconds, as the grebe zig-zags after its submerged quarry. Grebes also occasionally forage off the surface of aquatic vegetation (Muller and Storer 1999).
