==Behavior==

===Movement===
The Inca tern is essentially non-[[Bird migration|migratory]], although some disperse northwards after breeding. Some rogue individuals have flown great distances.<ref name=INTE-BOW/>

===Feeding===
The Inca tern feeds primarily on small fish, such as [[anchoveta]] (''Engraulis ringens''), and also consumes [[planktonic]] [[crustacean]]s and [[offal]] or [[carrion]] in its diet. Large flocks congregate around fishing boats and will also follow the feeding patterns of [[cormorant]]s, [[sea lion]]s, and [[whale]]s and [[dolphin]]s. Feeding flocks can number over 5,000 birds. The Inca tern catches its prey mainly by [[plunge-diving]], but also picks items from the surface while flying or floating on the water.<ref name=INTE-BOW/><ref name=Harrison/>

===Breeding===
Breeding does not appear to be concentrated in any season. Eggs have been found between April and July and between October and December, and other evidence of breeding has been noted in August. It nests in a variety of sites including fissures and caves in rock cliffs, among rocks and boulders on island slopes, in abandoned petrel and penguin burrows, and on and under human structures. The clutch size is usually two eggs though sometimes one. Both sexes incubate the clutch and provision the young. The incubation period is not known; fledging occurs about four weeks after hatch and the young are fully dependent on the adults for at least a month after fledging.<ref name=INTE-BOW/>

===Vocalization===
The Inca tern is most vocal at its nesting colonies. Its calls include "raucous cackling notes" and "mewing"; the latter call has been likened to that of a kitten.<ref name=INTE-BOW/><ref name=Harrison/>
