Twins.
Royal terns, Texas, Jan 24, 2012.
Big east wind for the 3rd day which means fewer birds in the yard.
This is from the archives.
Thalasseus maximus
Royal Tern chicks leave the nest scrape within one day after hatching and congregate in a group known as a crèche (“nursery”), which can contain thousands of chicks ranging in age from 2–35 days old. Each Royal Tern parent feeds only its own chick, finding it in the crowd probably by recognizing its call.
