The pelagic cormorant (Urile pelagicus), also known as Baird's cormorant or violet-green cormorant, is a small member of the cormorant family Phalacrocoracidae. Analogous to other smallish cormorants, it is also called the pelagic shag occasionally. This seabird lives along the coasts of the northern Pacific; during winter it can also be found in the open ocean. Pelagic cormorants have relatively short wings due to their need for economical movement underwater, and consequently have the highest flight costs of any bird.
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 IOC followed this classification in 2021. This is a smallish cormorant which measures 25 to 35 in (64 to 89 cm) in length, with a wingspan of about 3.3 ft (1.0 m) and a weight of 52–86 oz (1,500–2,400 g) when fully grown. Adults in nonbreeding plumage are all-black with a metallic iridescence. In breeding plumage they grow two short crests (one on top of the head and one at the nape), white thighs, and scattered white filoplumes on the head and neck. The long thin bill and the large...

Possible
About 20% of wildlife watchers report a Pelagic Cormorant sighting in Redwood National Park on a given day, based on 432 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 35th most-seen of the 226 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.
January and March
In those months about 30% of wildlife watchers report a Pelagic Cormorant in Redwood National Park on a given day, against about 10% in February, April, July and October, the lowest months. Those are among Redwood National Park's wettest months, with about 320 mm of rain a month against almost none in July.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Pelagic 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.
6th of 8
Of the 8 parks where we can rate Pelagic Cormorant sightings, Redwood National Park ranks 6th at about 20%. The best odds are in Kenai Fjords National Park (United States, about 60%), Great Bear Rainforest (Canada, about 30%) and Olympic National Park (United States, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Pelagic Cormorant is recorded against all the birds logged in Redwood National Park (432 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.
