Redhead vs Common Pochard

In short

The Redhead (Aythya americana) and Common Pochard (Aythya ferina) are both diving ducks that share similar habitats but are distinguishable through differences in size, plumage characteristics, and behavior. The Redhead has a more rounded head and a distinctive reddish-brown coloration, while the Common Pochard features a flatter head and a grayish body with a contrasting red head. Understanding these differences can greatly assist birdwatchers in accurate identification.

Identification tips

1. Birds of the World Similar-Species Diagnostics:

2. The Redhead is often confused with the Common Pochard due to their similar size and diving habits. However, the Redhead has a more rounded head and more vibrant reddish-brown coloration compared to the flatter-headed, grayish Common Pochard. The bill coloration is also a differentiating factor, with Redheads having a bluish bill with a black tip, while Pochards have a blue-gray bill.

3. AI Field Diagnostics:

4. Head Shape: Look for the head shape; Redheads have a rounded head while Common Pochards have a flatter head profile.
5. Coloration: Pay attention to the coloration; the Redhead's bright reddish-brown head is a key identifier, whereas the Common Pochard's head is a duller red.
6. Body Shape: When observed in the water, the Redhead has a more rounded and compact body compared to the longer and leaner Common Pochard.
7. Behavior: While both species dive, Redheads often forage in larger groups and exhibit more social behavior, while Common Pochards can be more solitary.
8. Vocalization: Listen for vocalizations; the nasal "kree" of the Common Pochard is distinct from the softer quacks of the Redhead.

By focusing on these identification tips, birdwatchers can confidently distinguish between the Redhead and the Common Pochard in the field.

Size

• Redhead: Typically measures about 36-41 cm (14-16 in) in length with a wingspan of approximately 81-87 cm (32-34 in). It has a stocky build.
• Common Pochard: Generally larger, measuring about 38-46 cm (15-18 in) in length and has a wingspan of around 80-88 cm (31-35 in). It also possesses a more elongated body shape compared to the Redhead.

Plumage

• Redhead: Males exhibit a striking reddish-brown head, a grayish body, and a black breast. Their bill is bluish with a black tip. Females are mottled brown with a slightly paler face and a characteristic dark cap.
• Common Pochard: Males are characterized by a flat, red head, a grayish body with a blackish breast, and a distinctive blue bill with a black tip. Females are brown and more uniformly colored, lacking the prominent cap seen in Redheads.

Behaviour

• Redhead: Known for its diving behavior and often forages in groups. They can be seen foraging for aquatic plants and seeds, and they tend to have a more pronounced courtship display.
• Common Pochard: Also dives for food but is known for its more solitary or small group foraging behavior. It often feeds on pondweeds, seeds, and some invertebrates.

Habitat

• Redhead: Prefers marshes and wetlands, particularly those with abundant vegetation and open water. They breed in North America and winter in coastal areas.
• Common Pochard: Found in a variety of freshwater and brackish habitats, including lakes and large wetlands. They breed in Europe and parts of Asia and migrate to southern Europe and Africa in winter.

Voice

• Redhead: Produces a series of soft quacks and whistles, especially during courtship displays.
• Common Pochard: Has a more nasal, "kree" call, which is distinct from the softer calls of the Redhead.
