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.

Speckle-breasted Wren
Pheugopedius sclateri
A distinctive medium-sized wren found from central Colombia to northwestern Peru. Occurs from sea level to around 1,600 m, locally higher. Warm brown above with a white eyebrow, streaked black-and-white face, and black spotting on breast. Tail and undertail coverts have strong barring. Pairs are found in the dense understory of scrubby woodland and edges. Listen for the loud sweet song phrases and the distinctive call, like running your finger up a comb.
Western Barn Owl
Tyto alba
Medium-sized owl with a heart-shaped facial disc and deep dark eyes; in parts of its range the only Tyto owl present, but compare with larger and darker-winged African Grass-Owl where overlap occurs. Varies across a wide range, but always note white-and-black speckling on the upperparts, beautiful gray-and-tawny wings, and large round head. Color of the facial disc and underparts varies from pure white to rusty orange. Hunts in open areas by night, foraging with a slow and buoyant flight. Roosts in old buildings, tree hollows, caves, and nest boxes by day. Gives a bone-chilling, rising shriek, as well as shorter rasping calls.
Moorland Francolin
Scleroptila psilolaema
A pretty, intricately marked medium-sized francolin. The white throat is spotted with black, and the wings show large rufous patches in flight. Found at high elevations in alpine grassland and heath, often in small groups. Similar to Orange River Francolin, but found in different habitat at higher elevations, and separated by the black-spotted throat. The vocalizations include a series of “cheedle-chee” notes, and a squealing call often given in flight.
