Narrative: Double-crested vs. Neotropic

The Double-crested Cormorant is the bigger, louder of the two. It’s got a hefty bill, a big orange throat patch, and during breeding season, sports two tiny black crests that look like it lost a bet involving a party wig.

The Neotropic Cormorant is slimmer, with a longer tail, a daintier bill, and a neat little white border around its throat patch. Its neck is long and serpentine, giving it a snake-charmer vibe as it weaves through the water.

Posture can help too. Double-cresteds look like they’re trying to sit up straight. Neotropics tend to slouch lower, stretch out, and look more aerodynamic.
