Like all cormorants, the Rock Shag feeds by diving for underwater prey.

Imperial and Rock Shags are present.

The Rock Shag usually nests on ledges on steep, bare, rocky cliffs.

Like a number of other species of cormorant that are commonly called shags, the Rock Shag is placed by some authors in a genus Leucocarbo.

At a distance, the Rock Shag is a black and white bird, with head, neck and upperparts black and chest and underparts white.

Colony attendance pattern of Rock Shags (Phalacrocorax magellanicus): an evidence of the use of predictable and low seasonally food sources?

The Rock Shag (Phalacrocorax magellanicus), also known as the Magellanic Cormorant, is a marine cormorant found around the southernmost coasts of South America.

The colonies are usually relatively small, but some consist of hundreds of pairs and are often shared with other seabirds such as Rock Shags, Southern Rockhopper Penguins and Black-browed Albatrosses.

If Leucocarbo is considered a distinct genus (which would probably require splitting up Phalacrocorax for the largest part), the Guanay Cormorant would also seem to belong here; alternatively, Leucocarbo could be expanded by several American species (including the Flightless Cormorant and Rock Shag).

The Rock Shag (Phalacrocorax magellanicus), also known as the Magellanic Cormorant, is a marine cormorant found around the southernmost coasts of South America.

The Guanay Cormorant is similar in coloration to the Rock Cormorant, Phalacrocorax magellanicus, but larger, measuring 78 cm from the tip of the bill to the end of the tail.
