Northern Shoveler (Eclipse Plumage)

Description:

Perhaps the most outwardly distinctive of the dabbling ducks, the Northern Shoveler inhabits wetlands across much of North America. Its elongated, spoon-shaped bill has comblike projections along its edges, which filter out food from the water.

Habitat:

wastewater treatment pond beside San Francisco Bay

Notes:

These shovelers were displaying an interesting cooperative feeding behavior while swimming around in a tight circle together.
