Brandt’s Cormorant
Brandt's Cormorant, found along the Pacific coast of North America, is distinguished by its sleek black plumage and striking blue throat patch during breeding season. Unlike many cormorant species, it dives from the surface to catch fish rather than swimming after them. One of its unique behaviors is its habit of "gular fluttering," where it rapidly vibrates its throat pouch to regulate its body temperature.
