December 21, 2016 – Sandwich Tern (Thalasseus sandvicensis)

These terns are found along much of the west coast of North America, and along the coasts of South America, Central America, Africa, Europe and Southern Asia. Their diet is made up of fish, which they catch by diving into the ocean, as well as shrimp, squid, worms, and insects. Building their nests on the ground in large colonies, both parents incubate the eggs and feed the chicks. If a nesting colony is disturbed, the chicks leave their nests and gather together in a large group called a “creche.” The chicks recognize their parents’ voices and leave the creche to feed when their parents call.
