This moulting adult Sanderling was almost pretty in the golden morning sun.
Among the several hundred terns there were 3 Gull-billed Terns. This juvenile was still being fed by a parent and was often begging.
While sitting around I wasted batteries and memory space on terns flying up and down the beach. 500 mm is really not the adequate lens for this type of photography.
