@wildlife.94: This black skimmer baby emerges when dinner arrives. As you can see on this chick, the upper and lower bill are the same length. This helps with being able to pick up food dropped on the ground by parents. At fledging at 4 weeks, the lower mandible will grow to nearly a half-inch longer than the upper. They use this unique design, by opening the bill and dropping the long, narrow lower mandible into the water, skimming along until they feel a fish. Then they relax the neck, quickly closing their jaws and whipping the fish out of the water.#wildlife
