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.
Conservation Status: There are currently no
perceived major threats to Common Pochard populations, and
the
IUCN cites it as a species of "Least Concern".
