Masked Booby vs Red-faced Cormorant

In short

The Masked Booby and Red-faced Cormorant are distinct in both appearance and habitat preference. The Masked Booby is a large, predominantly white seabird with a distinctive black mask, while the Red-faced Cormorant is smaller, dark-bodied, and has a striking red face during the breeding season.

Identification tips

1. Size and Shape: Look for the larger size and long wings of the Masked Booby. 2. Plumage: Note the white body and black mask of the Masked Booby versus the dark body and red face of the Red-faced Cormorant. 3. Habitat: Consider the location; Masked Boobies are found over open ocean, while Red-faced Cormorants are near rocky coasts. 4. Behavior: Observe feeding behavior; Masked Boobies plunge-dive, while Red-faced Cormorants dive from the surface.

Size

The Masked Booby is significantly larger than the Red-faced Cormorant, with a wingspan that can exceed 150 cm, compared to the cormorant's more compact build.

Plumage

Masked Boobies are mostly white with black on the wings and tail, and a black facial mask. Red-faced Cormorants are dark overall with a glossy sheen and a bright red face during breeding.

Behaviour

Masked Boobies are often seen soaring over open ocean and plunge-diving for fish, while Red-faced Cormorants dive from the surface and are more solitary, often seen near rocky coastlines.

Habitat

Masked Boobies are pelagic, found in tropical and subtropical oceans, nesting on remote islands. Red-faced Cormorants are coastal, preferring the North Pacific's rocky cliffs and inshore waters.

Voice

Vocalizations are not a primary distinguishing feature, as both species are relatively quiet, especially when compared to other seabirds.
