Silently watching a rookery island at sunset, I observed flocks of ibis, flocks of pelicans and flocks of snowy egret gently glide along the water to land on the island and take refuge for the night. One bird in flight is a graceful wonder to watch, but a flock of one species in flight together is a veritable ballet.

Seconds later, the flock extended their wings and feet to land on the rookery island. Zoom in to get a closer look!
