Where the name comes from

Phalacrocorax is “bald raven”, from phalakrós and kórax, for the pale patch some populations carry on the head; carbo is coal, for the colour. The English cormorant comes instead from the Latin corvus marinus, “sea raven”, by way of the French cormoran: three different languages looked at the same animal and all three saw a crow.

Characteristics

  • 01

    It stands with wings spread in the sun: the plumage is not fully waterproof.

  • 02

    It dives to thirty metres and can stay under for a minute.

  • 03

    It nests colonially in trees that the guano eventually kills.

What sets it apart

The plumage that soaks up water, which looks like a defect, is why it is such a good diver: absorbing water it loses buoyancy and sinks without effort. On this species and its relatives rests a very old trade — on the Nagara river in Japan, fishing with cormorants has been practised for thirteen hundred years, using a soft ring around the neck that lets the small fish through and holds the large ones. The fishermen are officials of the Imperial Household, and the post is hereditary.
