Audouin's Gull

Ichthyaetus audouinii

Elegant slim gull with long legs, and narrow wings. Adults have a light grey body with a paler white head. The wings are light gray with black tips, lacking conspicuous white spots. Legs are dark gray and the bill is dark red. Eyes are dark. Juveniles are similar to Lesser Black-backed Gull, with strongly barred underwings and a U-shaped white rump patch and dark tail. In their 1st winter they develop a gray-brown mantle and in their second winter the head is already white; the tail and secondaries have a black band.

Puna Ground-Tyrant

Puna Ground-Tyrant

Muscisaxicola juninensis

Fairly common, rather drab, small terrestrial flycatcher of puna habitats in the high Andes, especially bogs and lakeshores with rocky surroundings and bunchgrasses. Virtual absence of field marks is a field mark: plumage lacks strong contrast or color, but hindcrown has dull rusty blush, visible with good views, and face has very weak paler eyebrow. Much smaller than White-fronted Ground-Tyrant, which is often found in same areas.

African Spoonbill

African Spoonbill

Platalea alba

A distinctive pale waterbird with long pink-red legs, a bare bright pink-red face, and an odd and distinctive spoon-shaped bill that is obvious even in flight. The juvenile lacks the bright pink-red skin and has black tipped wings in flight. It breeds colonially in heronries. The African Spoonbill prefers large, quiet, shallow waterbodies where it forages by swinging its head from side-to-side, slicing its bill through the water, searching for small fish and aquatic invertebrates. It is mostly nomadic, wandering in response to local rainfall.

Mouse-colored Penduline-Tit

Mouse-colored Penduline-Tit

Anthoscopus musculus

A tiny drab bird with a sharp bill. Note gray back, whitish underparts, and faintly black-speckled forehead. Generally uncommon in dry savanna and thornscrub, usually found in pairs or small flocks. Similar to Sennar and African Penduline-Tits, but grayer on the back and paler below. Can also be mistaken for Yellow-bellied or Yellow-vented Eremomelas, but has a shorter and thinner bill and no yellow on the underparts. Vocalizations include high-pitched “sit” notes and long trills.
