Brandt’s Cormorant is the largest cormorant species found along the Pacific Coast. Known for its exceptional diving abilities, it can swim depths of over 200 feet in search of fish and shellfish. During the breeding season, Brandt’s Cormorant exhibits eye-catching features, including a vibrant cobalt-blue throat patch and eyes, along with wispy white feathers on its head.
This remarkable species is primarily found nesting and foraging in the California Current, which is a region of rich upwelling stretching from British Columbia, Canada to Baja California, Mexico. Due to the limited range in which it is observed, Brandt’s Cormorant is classified as a species on the Yellow Watch List.
The name of Brandt’s Cormorant pays homage to the renowned German zoologist Johann Friedrich von Brandt, who first described the species in the 19th century. Interestingly, its closest relative, the Spectacled Cormorant, is now extinct.

Distribution and Habitat of Brandt’s Cormorant
Brandt’s Cormorant is a fascinating seabird that can be found along the marine coastlines and estuaries of the Pacific Coast, stretching from Alaska to Mexico. It is a species that is highly adapted to its coastal habitat, with specific preferences for breeding and foraging.
This remarkable bird thrives in areas influenced by the California Current, which brings nutrient-rich waters up from the depths of the ocean. These upwelling zones provide an abundant food supply for Brandt’s Cormorant, making them ideal for breeding and raising their young.
Brandt’s Cormorant can often be observed in large flocks and breeding colonies, particularly on cliffs and rocky islands. These sites offer protection and nesting opportunities for the birds. The species is strictly coastal and rarely ventures over land.
An interesting feature of Brandt’s Cormorant is its utilization of kelp beds. These underwater forests provide additional shelter and food sources for the bird. In Mexico, they may also venture into nearby freshwater habitats along the coast.
During the nonbreeding season, populations of Brandt’s Cormorant redistribute along the coast, following the availability of food in different areas. This adaptability ensures their survival and allows them to thrive in their dynamic marine environment.
Key Points:
- Brandt’s Cormorant is found along the marine coastlines and estuaries of the Pacific Coast.
- They prefer areas influenced by the nutrient-rich California Current.
- They breed and forage in large flocks and colonies on cliffs and rocky islands.
- Brandt’s Cormorant utilizes kelp beds and occasionally visits freshwater habitats near the coast in Mexico.
- Populations redistribute along the coast based on food availability during the nonbreeding season.
