Gentoo Penguin
Pygoscelis papua
Attractive, medium-sized penguin that is rarely seen away from well-known colony sites. Appearance is distinctive with white “headphones” and a lipstick-orange bill unlike any other penguin. Striking head and bill pattern also make it one of the easiest penguins to identify when seen swimming at sea. Nests in small colonies and occurs around King and Magellanic Penguins in northern areas of its range, as on the Falklands.
Identification
The gentoo penguin is easily recognised by the wide, white stripe extending like a bonnet across the top of its head and its bright orange-red bill. It has pale whitish-pink, webbed feet and a fairly long tail – the most prominent tail of all penguin species. Chicks have grey backs with white fronts. As the gentoo penguin waddles along on land, its tail sticks out behind, sweeping from side to side, hence the scientific name Pygoscelis, which means "rump-tailed".<p>Gentoo penguins can reach a length of 70 to 90 cm (28 to 35 in), making them the third-largest species of penguin after the emperor penguin and the king penguin. Males have a maximum weight around 8.5 kg (19 lb) just before moulting and a minimum weight of about 4.9 kg (11 lb) just before mating. For females, the maximum weight is 8.2 kg (18 lb) just before moulting, but their weight drops to as little as 4.5 kg (9.9 lb) when guarding the chicks in the nest. Birds from the north are on average 700 g (1.5 lb) heavier and 10 cm (3.9 in) longer than the southern birds. Southern gentoo penguins reach 75–80 cm (30–31 in) in length. They are the fastest underwater swimmers of all penguins, reaching speeds up to 36 km/h (22 mph). Gentoos are well adapted to extremely cold and harsh climates.
Taxonomy
The gentoo penguin is one of three species in the genus Pygoscelis. Mitochondrial and nuclear DNA evidence suggests the genus split from other penguins around 38 million years ago (Mya), about 2 million years after the ancestors of the genus Aptenodytes. In turn, the Adélie penguins split off from the other members of the genus around 19 Mya and the chinstrap and gentoo finally diverged around 14 Mya.<p>There are 4 subspecies recognized by the International Ornithological Congress:<p>Although the population on the Kerguelen Islands is tentatively included in taeniata, it may also be a distinct subspecies.<p>Before 2021, only two subspecies of the gentoo penguin have been recognised: P. p. papua (subantarctic gentoo) and the smaller P. p. ellsworthi (Antarctic gentoo). However, a 2020 study suggested that the gentoo penguin be split into a species complex of four morphologically similar but separate species: the northern gentoo penguin (P. papua sensu stricto), the southern gentoo penguin (P. ellsworthi), the eastern gentoo penguin (P. taeniata) and the newly described South Georgia gentoo penguin (P. poncetii). The International Ornithological Congress incorporated the results of this study in 2021, but relegated the newly recognized or newly described species to being subspecies of P. papua.

Conservation
The population of Pygoscelis papua in the maritime Antarctic is rapidly increasing. Due to regional climate changes, they colonise previously inaccessible territories southwards.As of 2019[update], the IUCN Red List lists the gentoo as least concerned with a stable population trend, although rapid declines in some key areas are believed to be driving a moderate overall decline in the species population. Examples include Bird Island, South Georgia, where the population has fallen by two-thirds over 25 years.[1] Many threats to this species, including pollution, hunting, fishing and human recreational activities continue to affect them.[30][31]

African Thrush
Turdus pelios
This widespread thrush shows a large amount of geographical variation. The upperparts are generally gray-brown, while the underparts can be buff, gray, or rufous. All across the range, shows a yellow bill. Found in a range of habitats, including forest edge, woodland, gardens, and cultivation. In areas without Abyssinian Thrush, also occurs in montane forest. The song is a pretty, variable series of chatty whistles and trills which can continue for a long time without a pause. Similar to Abyssinian Thrush, but found at lower elevations in areas of overlap, and is generally paler, with a paler yellow bill.
Barred Cuckoo-Dove
Macropygia unchall
Shy brown dove of forests with dense understory. Wings and tail are dark brown, and the rest of the body is closer to tan. Males are boldly barred on the chest, and both sexes have a bronzy-green tinge to the nape. Seldom seen out in the open, this species is quick to flee when approached, flying strongly and quickly through dense vegetation. Appears longer-tailed than Spotted Dove and Turtle Dove, both when in flight and on the ground.
Barratt's Warbler
Bradypterus barratti
A skulky, dull brown warbler with a long and graduated tail, a pale grayish eyebrow, and a throat that is lightly streaked. It creeps around mouse-like in thick undergrowth and tangles in forest and forest edge. It is also found in isolated pockets of scrub, often adjacent to streams, and is frequently detected and identified by its song, mostly delivered between September and December: 2-3 sweet “tsiit” notes followed by a loud trill of 15-20 harsh “tchui” notes. It also has a strident chipping alarm call “tddd-ddr-ddr-ddr-ddr-tt.” The similar Knysna Warbler differs from Barratt’s Warbler by its shorter tail, darker underparts, less pronounced throat streaking, and different song.
