Brandt's cormorant (Urile penicillatus) is a strictly marine bird of the cormorant family of seabirds that inhabits the Pacific coast of North America. It ranges, in the summer, from Alaska to the Gulf of California, but the population north of Vancouver Island migrates south during the winter. Its specific name, penicillatus is Latin for a painter's brush (pencil of hairs), in reference to white plumes on its neck and back during the early breeding season. The common name honors the German naturalist Johann Friedrich von Brandt of the Academy of Sciences at St. Petersburg, who described the species from specimens collected on expeditions to the Pacific during the early 19th century.
It was formerly classified in the genus Phalacrocorax, but a 2014 study supported reclassifying it and several other Pacific cormorant species into the genus Urile. The IOU followed this classification in 2021. The average size of a Brandt's cormorant is 4.6 pounds. They have a length of about 34 inches and their wingspan is 4 feet. During the breeding season, adults have a blue throat patch.

Possible
About 20% of wildlife watchers report a Townsend's Cormorant sighting in Cabo Pulmo National Park on a given day, based on 45 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 39th most-seen of the 100 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February, September and December
In those months about 30% of wildlife watchers report a Townsend's Cormorant in Cabo Pulmo National Park on a given day, against about 10% in April–June and October, the lowest months. Those are among Cabo Pulmo National Park's wettest months, with about 45 mm of rain a month against almost none in April. July and August have too few records to rate.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Townsend's Cormorant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 8
Of the 8 parks where we can rate Townsend's Cormorant sightings, Cabo Pulmo National Park ranks 2nd at about 20%. The best odds are in Channel Islands National Park (United States, about 40%).
GBIF citizen-science records
It is estimated from how often the Townsend's Cormorant is recorded against all the birds logged in Cabo Pulmo National Park (45 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
