Double-crested Cormorants float low on the surface of water and dive to catch small fish. After fishing, they stand on docks, rocks, and tree limbs with wings spread open to dry. In flight, they often travel in V-shaped flocks that shift and reform as the birds alternate bursts of choppy flapping with short glides.

Unlike most waterbirds, the Anhinga doesn't have waterproof feathers. While that may seem like a disadvantage for their watery lifestyle, their wet feathers and dense bones help them slowly submerge their bodies under the water so they can slyly stalk fish.
