Common Pochard

About

The Common Pochard is a medium-sized diving duck with a distinctive silhouette and head shape. Males are particularly striking with their reddish-chestnut head and neck, grey body, and black breast and tail. Females are more subdued in coloration, generally grey-brown. They are expert divers, often seen foraging for aquatic vegetation and invertebrates in freshwater habitats.

Size & lifespan

Length

42-49 cm (17-19 in)

Wingspan

70-82 cm (28-32 in)

Weight

0.7-1.1 kg (1.5-2.4 lbs)

Lifespan

Typically 5-10 years in the wild, with records up to 20 years in captivity.

Diet

Primarily herbivorous, feeding on aquatic plants, seeds, roots, and tubers. Also consumes aquatic invertebrates such as insect larvae, molluscs, and small crustaceans, especially during breeding season.

Physical characteristics

Plumage

Adult male: Head and upper neck are rich reddish-chestnut. Breast and upper back are black. Flanks and belly are pale grey, contrasting with the black rear. Back and upperwing are pale grey. Undertail coverts are black. Bill is black with a distinctive broad blue-grey band near the tip. Eyes are red. Adult female: Head and body are duller brown. The crown and lines through the eye are often darker brown, sometimes with an indistinct paler patch between the eye and bill. Flanks are grey-brown. Bill is similar to male but often duller, with a less distinct blue-grey band. Eyes are brown. In flight, both sexes show a uniform pale grey upperwing bar.

Beak shape

Relatively long and broad bill with a slightly dished profile, black with a prominent blue-grey band across the middle.

Eye color

Adult male: Bright red. Adult female: Brown.

Leg color

Dull dark grey or greenish-grey with dark webbing.

Distinguishing features

The combination of the male's reddish head, grey body, and black breast, along with the distinctive bill pattern (black with a blue-grey band), are key. The steeply rising crown of the head forms a noticeable peak.

Juvenile appearance

Juveniles resemble adult females but are generally duller and more uniformly brown, with less distinct head markings and browner eyes. The bill pattern is less developed.

Seasonal changes

Males undergo an eclipse plumage after breeding (July-September), becoming duller and more female-like, but can be distinguished by the red eye and retain some darker markings. They regain their breeding plumage by late autumn/early winter.

Sexual dimorphism

Pronounced. Males are distinctly colored with reddish heads and grey bodies, while females are duller brown overall. Eye color also differs.

How to identify

1. 1

   Male Head/Body Coloration

   Look for the distinctive reddish-chestnut head and neck, contrasting with the black breast and mostly pale grey body. This combination is unique among European diving ducks.

2. 2

   Bill Pattern

   Observe the bill: it is black with a broad, prominent blue-grey band in the middle. This 'tricolour' bill pattern is a key field mark for both sexes, though less distinct in females and immatures.

3. 3

   Head Shape

   Note the distinctive head profile with a steeply rising forehead and peaked crown, especially noticeable on males. Gives the head a somewhat triangular appearance.

4. 4

   Eye Color

   Adult males have striking bright red eyes, which are visible even at a distance in good light. Females have brown eyes.

5. 5

   Flight Pattern

   In flight, look for the uniform pale grey bar on the upperwing of both sexes, which distinguishes it from species like Tufted Duck (white wing bar) or Ferruginous Duck (no prominent wing bar).

6. 6

   Female Plumage

   Females are primarily brown-grey, often with a darker crown and a paler area between the eye and bill. The bill pattern remains important for identification.

7. 7

   Diving Behavior

   Observe its behavior; Common Pochards are classic diving ducks, disappearing completely underwater for extended periods to feed.

Habitat & range

Biomes

Temperate grasslands, wetlands, and open water bodies.

Geographic range

Breeds across the Palearctic from Western Europe to Central Asia. Winters in Western and Southern Europe, North Africa, the Middle East, and South and Southeast Asia. Some populations are resident.

Elevation range

Primarily lowland species, typically found below 500 meters, but occasionally up to 1000 meters in some parts of its range.

Preferred environments

Large, shallow freshwater bodies with abundant submerged vegetation, such as lakes, reservoirs, slow-flowing rivers, and gravel pits. Also uses coastal lagoons and estuaries during winter. Prefers open water for feeding and safety, with reeds or other emergent vegetation for nesting cover.

Behavior

Activity time

Diurnal and nocturnal, actively feeding during both day and night, especially during clear moonlit nights.

Feeding habits

Diving duck, typically dives for food, staying underwater for 10-20 seconds. Uses its broad bill to dabble and scoop vegetation and invertebrates from the bottom. Feeds both during the day and night.

Social behavior

Highly gregarious, especially outside the breeding season, forming large flocks, sometimes mixed with other diving duck species. Males display to females in groups during courtship.

Flight pattern

Strong, direct, and fast flight with rapid wing beats. Takes off from water with difficulty, often running across the surface first. Typically flies in V-formations or lines during migration.

Migration pattern

Migratory over much of its range, moving from colder northern breeding grounds to milder southern wintering areas. Some southern populations are resident. Migration typically occurs in broad fronts.

Territoriality

Males are not strongly territorial on breeding grounds, but defend their mate. Nests are often placed in loose colonies or individually within suitable vegetation.

Breeding & reproduction

Breeding season

April to July, depending on latitude.

Nesting habits

Nests are typically built in dense emergent vegetation near water, such as reeds, sedges, or rushes. The nest is a substantial bowl of plant material, lined with down. Nests are often well concealed.

Clutch size

Typically 8-10 eggs, but can range from 6 to 14. Larger clutches may result from 'dump nesting' by multiple females.

Egg description

8-10 (sometimes 6-14) smooth, glossy, pale greenish-grey to buff eggs.

Incubation period

24-28 days, primarily by the female.

Fledging period

50-55 days. Young fledge and become independent.

Parental care

Mainly by the female, who leads the ducklings to feeding grounds and protects them. Males typically desert the female during incubation.

Where to find

Field tips

1. Scan Open Water. Pochards spend most of their time on open water. Use binoculars or a scope to scan large expanses of lakes for their characteristic diving behavior and distinctive male plumage.
2. Look for Mixed Flocks. Outside of breeding, Common Pochards often associate with other diving ducks like Tufted Ducks or Greater Scaup. Carefully examine each bird in a mixed flock.
3. Observe Diving. Watch their diving pattern. They typically make small, head-first dives, disappearing completely and resurfacing a short distance away.
4. Check Bill and Eye Color. These are crucial identification features, especially for distinguishing between similar species and sexes. The blue-grey bill band and red male eye are key.
5. Visit During Winter. Numbers often peak in wintering grounds, making them easier to find and observe in larger flocks.
6. Consider Time of Day. They can be active at any time, but early morning or late afternoon might offer calmer conditions for observation.

Fun facts

• The name 'Pochard' is derived from the Old French 'pochard,' meaning 'to poach' or 'to poke,' referring to its diving and bottom-feeding habits.
• Common Pochards can dive to depths of several meters to find food, staying submerged for up to 30 seconds, though typically less than 20.
• They are known to hybridize occasionally with other Aythya species, such as Tufted Ducks and Ferruginous Ducks.
• During their post-breeding eclipse plumage, males can be quite challenging to identify, often resembling females or even juvenile birds.
• Their strong, direct flight makes them appear quite robust in the air, a contrast to their somewhat clunky appearance when taking off from water.
