SPONSORED ADVERTISEMENTS

General

Blue-gray Noddy: Small tern with a short, slender, straight black bill and partial white eye ring; pale gray plumage with slightly lighter underparts; darker gray on back and rump, tinged brown-gray on upperwings, and black-gray on primaries; small black spot on front; slightly forked tail; black legs; black-brown iris. Non-breeding adults are slightly lighter. Sexes are similar. Races vary mostly by plumage tone. Juveniles have browner plumage and darker, contrasting flight feathers.

Breeding and Nesting

Blue-gray Noddy: Usually, one egg is laid in a roughly constructed nest made from shreds of grass and seaweed which has been placed on a cliff face, in a crevice or hollow, or under a ledge. The egg is incubated by both the male and female for around 32 days. The adults brood the chick for two to three weeks after hatching. The chick typically fledges at around 37 days old.

Foraging and Feeding

Blue-gray Noddy: These noddies forage by picking off tiny fish, squid, insects, sea-skaters and small crustaceans. They generally forage in small groups close to the shore, flying low over the water and using quick, shallow wing-beats before dipping to snatch prey from the surface. They often hover close to the water, pattering their feet on the surface, when searching for prey.

Vocalization

Blue-gray Noddy: Generally silent, but may emit a rather harsh, warbling sounds. Call is a soft, purring sound.

Similar Species
