Male Anhinga Taking a Stance

While touring Wakulla Springs in Florida last December we learned about the Anhinga bird.

Though these birds look similar to the common Cormorant, the more rare Anhinga's sport a sharp pointed bill. Here we caught this male drying his wings in the afternoon sun, as they typically dive deep in water while they fish. Their bones are more dense than most birds and lack buoyant feathers, all to help reach greater depths while fishing. After a deep and waterlogged hunt, they tend to spread their large wings in the sun to warm up their bodies.
