Both cormorant species depend upon the habitat to deter predator access: the Double-crested Cormorant utilizes a defense regime of energetic and aggressive behaviors; the Pelagic Cormorant uses a much less effective defense Pelagic cormorants form nests from stringy plants such as grasses and seaweeds and hold it all together with their guano. Sociable at all seasons, it is often seen flying in long lines low over the water. (n.d.). Their clutches are generally two to five eggs but the highest recorded was 7 eggs. At colonies, disturbance causes nest losses to predators and nest abandonment. Data includes things like the location of bald eagle nests and interaction they see between cormorants and bald eagles. They also eat crustaceans, marine worms, and other invertebrates, swallowing smaller prey while still underwater but bringing larger items to the surface to soften before swallowing. Lawonn and Gatens both noted the bald eagles attack cormorants. The majority of the North American pelagic cormorants nest in Alaska, with an estimated population of 50,000 pairs. The Sibley Guide to Birds, second edition. Along the mainland coast, most foraging occurs within about one mile from shore. They are costal birds which can also colonise inland waters, such as lakes. []), to temperate upwelling ecosystems such as the Benguela system (e.g., Ref. Pelagic cormorants make low groans and calls similar to gulls. The angle of its forehead where it joins the beak is shallower and the yellow skin around the face is more extensive. We selected this photograph to emphasize that bird and mammal fish predators can be found together in space and time and often forage on the same resources. According to the North American Bird Breeding Survey, the population has decreased overall from 1966 to 2014. The pelagic cormorant, like other cormorants, does not have totally waterproof feathers. They also tend to prefer to be isolated from all other animals, including their own species, but occasion will be seen nesting together. Hobson, Keith A. After breeding, the pair separates for 7–8 months. Thousands of Pelagic Cormorants perished in the Exxon Valdez oil spill in Alaska in 1989. Family: Phalacrocoracidae They may remain underwater for over 2 minutes in pursuit of fish, hunting both those that hide in rocky reefs and those that school beneath the surface. Retrieved from https://www.allaboutbirds.org/guide/Pelagic_Cormorant/id. They also sometimes nest on structures such as disused bridges, piers, ships, towers, or navigation aids. They are also known to be found hunting in mixed species groups because they are attracted by other feeding birds. Most pairs raise two pairs at most each season. Males select and defend nest sites, usually on narrow ledges on inaccessible rocky cliffs, facing the sea, sometimes on structures such as shipwrecks, bridges, or navigation towers. Lance and A.C. Thomas. Pelagic Cormorants eat mostly fish, which they capture at depths as great as 138 feet, seizing prey with the hooked bill. They catch most their prey underwater. Version 2.07.2017.

Pelagic Cormorants stay close to coastal shorelines and islands, rarely venturing far out to sea. Relatives. 2001), human disturbance (Verbeek 1982, Carter et al. Scientists will quantify their numbers and locations along the North Coast, as well as their reproductive rates, diet and related interannual variance at select colonies to identify how these important marine predators are being affected by the new MPAs, human disturbance and ever-changing ocean conditions. During the breeding season, these species mainly forage within a few miles of colonies (Briggs et al. Your email address will not be published. The Pelagic Cormorant (Phalacrocorax pelagicus) is the most widespread cormorant in the North Pacific, but little is known about its foraging and diving behavior. Cormorant populations have also decreased from oil spills and contamination of prey. Groups roost together on rocks near water, and feed in flocks offshore, often associating with other seabirds. A., M. J. Steinkamp, K. C. Parsons, J. Capp, M. A. Cruz, M. Coulter, I. Davidson, L. Dickson, N. Edelson, R. Elliott, R. M. Erwin, S. Hatch, S. Kress, R. Milko, S. Miller, K. Mills, R. Paul, R. Phillips, J. E. Saliva, W. Sydeman, J. Trapp, J. Wheeler and K. Wohl (2002). Since other predators in the California Current also seem to follow this one-third rule, then other predators in systems around the world may follow it as well.
