Tufted Puffin vs Cassin's Auklet

Tufted Puffins and Cassin's Auklets are both members of the Alcidae family, but they are easily distinguished by size and plumage. The Tufted Puffin is much larger with a striking appearance, while Cassin's Auklet is smaller and more subdued in coloration.

1. Look for size difference: Tufted Puffins are much larger. 2. Note the striking plumage of the Tufted Puffin: white face mask and golden plumes. 3. Observe the bill: Tufted Puffins have a large, bright orange bill, while Cassin's Auklets have a smaller, less colorful bill. 4. Consider habitat: Tufted Puffins are often seen on rocky cliffs, while Cassin's Auklets are more likely found nearshore.

The Tufted Puffin is significantly larger than Cassin's Auklet, making size a reliable field mark when both species are observed together.

Tufted Puffins have an all-black body with a distinctive white face mask, bright orange bill, and golden head plumes. In contrast, Cassin's Auklets are smaller, with a more uniform grayish-brown plumage and lack the dramatic facial features of the puffin.

Tufted Puffins are more pelagic and often seen carrying fish in their bills, while Cassin's Auklets are less conspicuous, often feeding on invertebrates closer to shore.

Tufted Puffins breed on rocky islands and cliffs from California to Alaska, while Cassin's Auklets prefer nesting in burrows on offshore islands along the Pacific coast.

Vocalizations are not a primary distinguishing feature in the field for these species, as both are relatively quiet at sea.
