Double-crested Cormorants In Their Prime

In New England, if you don’t live on the coast or in a couple of inland locations, you will probably only see Double-crested Cormorants as they pass through during migration.  At first sight, these birds aren’t especially eye-catching – blackish-brown, somewhat prehistoric-looking, often seen perched with wings stretched out to dry. Hardly worth a second look, some might say, but in the spring they would be mistaken.

During their breeding season Double-crested Cormorants’ eyes are a brilliant turquoise color, and they develop the tufts of feathers, or crests, on their head for which they are named. Should you see one in the spring, watch for it to open its beak – the inside of their mouth is also bright turquoise at this time of year!

  2. That is absolutely fascinating that their eye color and tongue color would change during mating season! Fantastic! Great information as always Mary! Thank you! 🙂 ❤

    I just read that they were also threatened by the use of DDT, but have fortunately made a comeback.
