Mediterranean Gull
Ichthyaetus melanocephalus
Medium-sized gull, slightly larger than Black-headed Gull, more similar to Common Gull in size and shape but bill stouter. Adult is distinctive, the only small gull with snow-white wingtips; breeding plumage has black hood. Nonbreeding and immature have distinctive, dark smudges behind each ear. Juvenile has mottled brownish back, which molts to pale gray by winter. Breeds in typically water-adjacent colonies scattered throughout Europe and Western Asia, often with Black-headed Gulls. Frequently found with flocks of other medium-sized gulls outside of the breeding season.
Identification
The Mediterranean gull is slightly larger and bulkier than the black-headed gull with a heavier bill and longer, darker legs. The breeding plumage adult is a distinctive white gull, with a very pale grey mantle and wings with white primary feathers without black tips. The black hood extends down the nape and shows distinct white eye crescents. The sharp-tipped, parallel sided, dark red bill has a black subterminal band. The non breeding adult is similar but the hood is reduced to an extensive dusky "bandit" mask through the eye. This bird takes two years to reach maturity. First year birds have a black terminal tail band and more black areas in the upperwings, but have pale underwings.

Behavior
This gull breeds in colonies in large reed beds or marshes, or on islands in lakes; where its population is small, it nests in black-headed gull colonies. Like most gulls, it is highly gregarious in winter, both when feeding or in evening roosts. It is not a pelagic species, and is rarely seen at sea far from coasts.<p>The Mediterranean gull's feeding habits are much an opportunistic omnivore, eating fish, worms, insects, eggs, young birds, offal and carrion.<p>This is a noisy species, especially at colonies, with a nasal "yeah" call.
Conservation
The Mediterranean gull is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

Coscoroba Swan
Coscoroba coscoroba
A distinctive white swan with a bright, rather ducklike bill. The black wingtips are usually concealed when swimming. Most likely to be confused with white domestic waterfowl. Fairly common but sometimes local on lakes, slow-moving rivers, wetlands with open water, estuaries, and inshore coastal waters. Often in groups and associates readily with Black-necked Swan. Cygnets are dirty brownish with a black face mask, but young look much like adults within a month or two after hatching. Name comes from slightly gruff, honking “kós-ko roa” call.

Yellow-eyed Penguin
Megadyptes antipodes
A tall, stocky penguin endemic to New Zealand. Note the conspicuous soft, yellow uncrested band that stretches across the back of the head to circle each distinctly yellow eye. Juveniles have paler eyes, lack the yellow band, and are paler at the back of the head. Breeds on the southeast coastline of the South Island and on Stewart, Codfish, Campbell, and Auckland Islands. Feeds alone at sea, but can form small groups in the non-breeding season. Adults sedentary at colony sites. Juveniles sometimes encountered as stragglers, dispersing as far north as the Bay of Plenty.

Peg-billed Finch
Acanthidops bairdi
Dull medium-gray finch with oddly long pointed bill, usually with pinkish or yellowish lower mandible. Female browner than male, with brown wingbars, but bill shape still very distinctive. Found at high elevations, usually above 1500m, in brushy areas or scrubby forest. Almost always found around seeding bamboo.
