I will sometimes see other birds open their wings and stretch them out for a moment, but the Double-crested Cormorant (Phalacrocorax auritus) is the only bird that I have observed that leaves its wings open for an extended period of time.
Initially I was confused when I heard the cormorant had to dry out its wings because they got waterlogged. How does a waterbird survive if its wings are not waterproof?
The Cornell Lab of Ornithology, my favorite website for information about birds, provides the following explanation of this phenomenon:
“They have less preen oil than other birds, so their feathers can get soaked rather than shedding water like a duck’s. Though this seems like a problem for a bird that spends its life in water, wet feathers probably make it easier for cormorants to hunt underwater with agility and speed.”
