Many authorities consider it a subspecies of the Imperial Shag.

There are also two small colonies of Imperial Shags.

Imperial Shags also nest at the site.

One of the birds collected and described by King is the Imperial Shag.

It is often considered conspecific with some other blue-eyed shags under the name Imperial Shag.

Other birds nesting at the site include Southern Giant Petrels and Imperial Shags.

Blennies in this species are preyed upon by the Imperial Shag (Phalacrocorax atriceps).

Imperial Shag, Phalacrocorax (atriceps) atriceps, from coastal southern Chile and Argentina.

Magellanic Penguins, Imperial Shags and Sooty Shearwaters are present.

In accordance with the treatment there, the Imperial Shag complex is here left unsplit as well, but the King Shag complex has been.

Other birds known to nest on the island include Imperial Shags, Snow Petrels and Kelp Gulls.

The Imperial Shag is a cormorant which is native to many subantarctic islands, the Antarctic Peninsula and southern South America.

Close to Port Lockroy, we may also offer a landing on Jougla Point, with Gentoo Penguins and Imperial Shags.

Similarly, Leucocarbo would refer to the group around the Imperial Shag (P. atriceps) complex, which occurs on the opposite end of the Earth from P. pelagicus.

The South Georgia Shag is one of the blue-eyed shags, sometimes placed in the genera Leucocarbo, and a subspecies of the Imperial Shag.

Other birds nesting at the site in smaller numbers include Adélie Penguins, Imperial Shags, Wilson's Storm Petrels and South Polar Skuas.

The site has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of about 180 pairs of Imperial Shags.

Birds for which the site is of conservation significance include Southern Rockhopper Penguins (1700 breeding pairs), Imperial Shags, Striated Caracaras (8-10 pairs), and Cobb's Wrens.

DEWHA (Department of the Environment, Water, Heritage and the Arts) - Leucocarbo atriceps purpurascens - Imperial Shag (Macquarie Island).

The site is an IBA because it supports colonies of breeding seabirds, jncluding Adélie Penguins (11,500 pairs), Macaroni Penguins, Southern Giant Petrels and Imperial Shags.

Other birds nesting in the group in smaller numbers include Macaroni Penguins (350 pairs), Southern Giant Petrels, Imperial Shags, Cape Petrels, Wilson's Storm Petrels, Snowy Sheathbills and Kelp Gulls.

In recent years, three preferred treatments of the cormorant family have emerged: either to leave all living cormorants in a single genus, Phalacrocorax, or to split off a few species such as the Imperial Shag complex (in Leucocarbo) and perhaps the Flightless Cormorant.

Its breeding range overlaps markedly with that of the Imperial Shag Leucocarbo atriceps, but the two species' foraging ranges are different since the Imperial Shag tends to dive in deeper water, further out from shore.

Other species found nesting at the site are South Polar Skuas, Southern Giant Petrels, Black-bellied and Wilson's Storm Petrels, Cape Petrels, Imperial Shags, Snowy Sheathbills, Brown Skuas, Kelp Gulls and Antarctic Terns.
