Steller was the only naturalist to report seeing the Spectacled Cormorant alive.

The extinct spectacled cormorant from Bering Island.

By 1850, fewer than 100 years after Steller first saw these seabirds, the Spectacled Cormorant became extinct.

It is from a bird roughly the size of a Spectacled Cormorant, and quite similar to the corresponding bone in Phalacrocorax.

Spectacled Cormorant, Phalacrocorax perspicillatus - extinct (c.1850)

The Spectacled Cormorant, a large essentially flightless bird in the cormorant family, was similarly driven to extinction by around 1850.

The recently-extinct Spectacled Cormorant (Phalacrocorax perspicillatus) was rather larger, at an average size of 6.3 kg (14 lb).

Two Bering Sea species, the Steller's Sea Cow and Spectacled Cormorant, are extinct because of overexploitation by man.

One such species is the Spectacled Cormorant (Phalacrocorax perspicillatus); a large, nearly flightless seabird that lived on a few remote islands at the western end of the Aleutian chain.

The hunting of seabirds and the collecting of seabird eggs have contributed to the declines of many species, and the extinction of several, including the Great Auk and the Spectacled Cormorant.

Examples include Asian Brown Flycatcher, Long-billed Murrelet, Spectacled Cormorant, Hill Pigeon, Steller's Sea Eagle, Caspian Gull and White-naped Crane.

This is a North Pacific clade, which apart from Brandt's and the Pelagic Cormorant also includes the Red-faced Cormorant (P. urile) and probably also the extinct Spectacled Cormorant (P. perspicillatus).

The Spectacled Cormorant or Pallas's Cormorant (Phalacrocorax perspicillatus) is an extinct marine bird of the cormorant family of seabirds that inhabited Bering Island and possibly other places in the Komandorski Islands and the nearby coast of Kamchatka.

Of the 6 species of birds and mammals that Steller discovered during the voyage, two are extinct (the Steller's sea cow and the Spectacled Cormorant), and three are endangered or in severe decline (Steller's sea lion, Steller's Eider and Steller's Sea Eagle).

The Dodo, Pallas's Cormorant and Great Auk may be extinct bird species - but they, and dozens more winged creatures no longer with us, have been brought back to life for a new exhibition in London that aims to raise awareness of the need for bird conservation.
