The yellow-billed tern forages during the day, mostly on small fish, shrimp, and insects. It feeds by hovering and picking fish from surface waters.
It frequently nests alongside colonies of the large-billed tern (Phaetusa simplex ) and the black skimmer (Rynchops niger ). The yellow-billed tern breeds from August to December on sand banks and island beaches. Non-breeding season habitats include coastal lagoons, river mouths, and rice fields. Their nests consist of shallow scrapes in the sand. Most commonly a clutch contains 2 eggs, but the yellow-billed tern can lay anywhere between 1–4 eggs. The incubation period is approximately 24 days. Nests are usually formed very close to each other. Terns aggressively defend their nests from predators, and other species such as the sand-colored nighthawk (Chordeiles rupestris ) have been known to nest among tern colonies to take advantage of this anti-predator behavior.
