The Common Pochard is a common diving duck of Eurasia. They are only extremely rare vagrants in North America, with most sightings happening in the Aleutians or western Alaska, but sightings have also occurred in California and Saskatchewan. They are ecological counterparts, and very similar to, the Redhead duck that is found in North America.
Habitat
Found on a variety of water bodies (lakes, reservoirs, and slow moving rivers), but in general requires open water habitat of shallow to moderate depth, with surrounding aquatic vegetation that supports prey items such as snails, mollusks, and aquatic insects. They will occasionally use brackish water areas or sheltered coastal bays, but they strongly prefer inland, fresh water bodies.
Diet
Omnivorous, feeding on both plant and animal matter. Food items may include aquatic plants (seeds, stems, leaves, and roots), algae, aquatic insects and their larvae, small mollusks and crustaceans, and occasionally small fish.
Behavior
Typically a diving duck, diving and swimming under water for food, but they will also upend and feed with just their head under the water. They will also sometimes dabble near the water's surface. Gregarious, sometimes forming very large flocks on their wintering grounds, oftentimes mixing with other species such as Tufted Duck .
Nesting
The nest of a Common Pochard is a shallow depression in thick vegetation, usually within 20-30 feet of a lake or river shoreline. Females incubate the eggs and tend to the young after hatching, but the young must find their own food.
Migration
Most populations are migratory, especially those in the northern half of their range. They breed throughout large swaths of Europe and Asia. Wintering grounds include southern and eastern Asia, western Europe, and northern Africa.
