When seeing this Great Blue Heron from a distance, I thought it was stuck in a piece of driftwood until I realized it was his wings I was seeing. I had never spotting a heron sunning his wings before so it was an interesting pose to capture.
Birds assume one of several wing postures to sun – such as spread wing, droop wing and delta wing. I believe this pose is referred to as the delta wing sunning pose. Besides sunning, the wings may be held out to dry it feathers, lose heat, show off to rivals or to shades its eggs or babies.
