|Gygis alba||Order: Charadriiformes||Family: Laridae (Gulls, Terns, and Skimmers)|
This ethereal seabird is found across the tropical oceans of the world. It does not build a nest, but lays and incubates its single egg on a fairly thin branch or crotch. Chicks hatch out with sturdy gripping toes to survive.
I’ve never photographed this species. The photo here was taken by B. Navez.
