Double-crested Cormorant

Double- crested Cormorant


The Double-crested Cormorant (Phalacrocorax auritus) is a member of the cormorant family of seabirds. It occurs along inland waterways as well as in coastal areas, and is widely distributed across North America, from the Aleutian Islands in Alaska down to Florida and Mexico. Measuring 70–90 cm (28–35 in) in length, it is an all-black bird which gains a small double crest of black and white feathers in breeding season. It has a bare patch of orange-yellow facial skin. Five subspecies are recognized.

The double-crested cormorant is found near rivers and lakes and along the coastline. It mainly eats fish and hunts by swimming and diving. Its feathers, like those of all cormorants, are not waterproof and it must spend time drying them out after spending time in the water. Once threatened by the use of DDT, the numbers of this bird have increased markedly in recent years.

  1. Great post, HJ. We are so lucky to have abundant cormorants on this earth, such remarkable birds. I wasn’t aware that they were a species diminished by DDT. Enjoyed your photos too, and the last one gives good size perspective. I like their raggedy tail tip, and the first photo defines it beautifully.

    • While in Peru I visited some islands entirely dedicated to mine super rich “guano” strata accumulated for many year of seabirds, which cormorants were great contributors. The high quality of this guano was more valuable than gold, for the great concentration of nitrate. It was excellent for use of fertilizer and making of explosives. Peru was the first exporter in the world. The old Incas knew about fertilizers and grew excellent crops for all their population.
      The cormorants are better swimmers and divers than flyers. Thank you my dear friend… 🙂

  2. I love cormorants, they are so beautiful. We have a lot in our island and it’s always fun to to observe them.
