Atlantic puffin ID features?

• A. Colorful beak, nests on islands
• B. Long snout, horse-like face
• C. Small triangular dorsal fin
• D. Round head, short snout

Answer: (A)

The key to recognizing Atlantic puffins is their standout breeding-season appearance and behavior. In season, puffins sport a large, brightly colored beak—orange with blue and yellow highlights—that is highly distinctive and often the quickest cue from a distance. They also nest in colonies on islands, digging burrows or using natural crevices in grassy, rocky island settings and returning there to raise a single egg.

This combination—a vividly colored beak and island burrow nesting—is what sets puffins apart from other seabirds. The other options describe features that don’t match puffins: a long snout would point to a different animal, a small triangular dorsal fin is not a bird, and a round head with a short snout lacks the defining, colorful beak and island-nesting behavior. Remember, outside the breeding season the beak color fades, so the distinctive behavior and body shape help with identification in those times.
