Rhinoceros Auklet vs Tufted Puffin

In short

The Rhinoceros Auklet is distinguished by its prominent 'horn' above the bill, while the Tufted Puffin features striking golden head plumes and a bold white face mask. Both species share a similar auk-like structure but differ significantly in plumage and behavior.

Identification tips

• Breeding season: Look for the Rhinoceros Auklet's 'horn' on the bill.
• Plumage: Note the Tufted Puffin's golden head plumes and white face mask.
• Behavior: Observe activity patterns; Rhinoceros Auklets are more active at night, while Tufted Puffins are active during the day.
• Location: Consider habitat; Rhinoceros Auklets are closer to shore, Tufted Puffins are more pelagic.

Size

Both species are medium-sized auks, but the Tufted Puffin is generally more robust.

Plumage

The Rhinoceros Auklet has a more subdued plumage with a grayish body and a distinctive 'horn' on the bill during breeding season. In contrast, the Tufted Puffin is all black with a bold white face mask, bright orange bill, and long golden head plumes.

Behaviour

Rhinoceros Auklets are primarily nocturnal at breeding colonies, while Tufted Puffins are more diurnal. Both species carry fish in their bills, but the Rhinoceros Auklet is unique in carrying fish externally at night.

Habitat

Rhinoceros Auklets are found in temperate North Pacific waters, often closer to shore. Tufted Puffins have a broader range, from southern California to the Alaskan Arctic, and are more pelagic.
