Royal Tern

Royal Tern: Large tern, pale gray upperparts; white face, neck, and underparts. Head has spiky, black crest and cap, and heavy, bright orange bill. Wings are black-tipped above and black-edged below; tail is deeply forked. Legs and feet are black. Hovers before plunge diving for prey.

● Song: "kee-rare"

● Foraging & Feeding: Royal Tern: Feeds on small fish and aquatic invertebrates, including crabs, squid, and shrimp. Plunge dives to capture prey; occasionally pirates fish from other birds, especially Brown Pelicans.

● Breeding & nesting: Royal Tern: One to four creamy buff to brown eggs with red brown markings are laid in a depression in sand or a cup of dead grass, usually built on a sandy or rocky island. Incubation ranges from 20 to 31 days and is carried out by both parents.

● Similar species: Royal Tern: Elegant Tern is smaller, has a more slender red-orange bill that appears slightly drooped at tip, and longer shaggy crest that extends down nape. Caspian Tern has a thicker, red bill, dark wedge on outer portion of underwings, weaker forked tail, and near complete cap in winter and juvenile plumages.

Flight Pattern

Direct flight with deep steady wing beats.
