Appearance, physical description and identification

The white-eyed gull (Ichthyaetus leucophthalmus) is a small gull, measuring 40 to 45 cm in length and weighing 270 to 420 grams. The wingspan is 110 to 120 cm.

The upperparts, upper wings and underwings are dark gray. The breast is pale gray. The belly, vent region and undertail are whitish. The tail is blackish gray with pale gray tip. The bill is long and slender. In white-eyed gull juveniles the bill is black and in adults it is red with black tip. The legs are yellow.

In breeding white-eyed gull adults, there is a black hood extending down to throat. There is a whitish band on either side of the neck below the hood. In non breeding adults the hood is flecked with small whitish spots. The juveniles have brownish-grayish plumage. Their call is a distinctive harsh "kioow..kioow" sound.

Ecosystem and habitat

These white-eyed gull species do not normally occur in forest. These species occur in altitudes from 0 to 100 meters. These white-eyed gull species inhabit natural marine ecosystems.

The white-eyed gull marine ecosystems include rocky offshore islands, rocky shoreline, sandy shoreline, sand bars, sandy beaches, marine intertidal pools, shallow seas with submerged growth of macroalgae like sea grass and kelp and subtidal rocks and rocky reefs.

Diet and feeding behavior

The diet of these white-eyed gulls is mostly fish. Crabs, shrimps, molluscs, fish, annelids and fruits are their primary food. They plunge dive and catch their prey. They are known to scavenge and eat offal and dead animals. They also predate on the eggs and nestlings of other small birds.

Reproduction and breeding habits

The breeding season of these white-eyed gull species is during June to August with peak laying in July. These gulls mostly breed in inshore islands with rocky and sandy beaches in the Gulf of Aden and islands at the mouth of the Gulf of Suez.

These gulls often nest in loose colonies on rocks, sandy beaches or exposed flats. The nests in sandy substrate have twigs, seaweed and debris as an outer ring. The nests on rocks are lined with plant matter. The typical clutch consists of two or three eggs.

Migration and movement patterns

The white-eyed gull is a non-migrant sedentary bird.

Post breeding, the white-eyed gull juveniles may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range. In non-breeding season, there may be nomadic movements around the breeding range. Sometimes they form large foraging flocks.

Conservation and survival

The global population size of the white-eyed gull (Ichthyaetus leucophthalmus) has not been quantified. The overall population trend of these species is considered to be stable. Throughout its range it is reported to be rare to common. The generation length is 11 years. Their distribution size is about 403,000 sq.km.

The white-eyed gull (Ichthyaetus leucophthalmus) is approaching the thresholds for being Vulnerable, under the range size criterion, under the population trend criterion and also under the population size criterion. Risk from introduced predators on the breeding islands, oil exploration, oil-spills, egg and chick collection and hunting for food are the main threats that may endanger the survival of these gull species.

IUCN and CITES status

The IUCN (International Union for Conservation of Nature) has categorized and evaluated the gull species and has listed it as "Near Threatened". CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) status is ‘Not Evaluated’ for the white-eyed gull (Ichthyaetus leucophthalmus).
