Pharaoh Eagle-Owl
Bubo ascalaphus
Smaller and paler than Eurasian Eagle-Owl but with a more accentuated facial pattern and paler yellow eyes. Also note more limited streaking on the underparts than Eurasian Eagle-Owl. Favors arid habitats. Song and call is higher-pitched than Eurasian Eagle-Owl.
识别特征
The Pharaoh eagle-owl has a mottled plumage and large orange-yellow eyes. The head and upperparts are tawny and densely marked with black and creamy-white streaks and blotches, while the underparts are pale creamy-white, with black streaks on the upper breast and fine reddish-brown vermiculations on the lower breast and belly. The face has the disc-like form typical of most owls, defined by a dark rim, the robust bill is black and hooked, and the head is crowned with small ear tufts. With a body length of 46–50 cm (18–20 in), it is one of the smaller eagle-owl species. There are two recognised subspecies of the Pharaoh eagle-owl, the Pharaoh eagle-owl (B. a. ascalaphus) and the desert eagle-owl (B. a. desertorum), the latter being smaller and paler with sandier colouration.

分布与栖息地
The Pharaoh eagle-owl is native to much of arid Northern Africa, including some of the most desolate parts of the central Saharan Desert, where it may be found in Algeria, Chad, Egypt, Eritrea, Libya, Mali, Mauritania, Morocco, Niger, Senegal (vagrant owls), Sudan, Tunisia and Western Sahara. Its range extends eastward into the Arabian Peninsula and the Middle East, where it is found in Iran, Iraq, Israel, Jordan, Kuwait, Oman, Palestine, Qatar, Saudi Arabia, Syria and the United Arab Emirates. Its preferred habitat is mostly open, barren plains or desert with scattered palms or other endemic plants, where it nests in rocky outcrops, wadis and cliffs.

行为
The Pharaoh eagle-owl is nocturnal and emerges at dusk to hunt over an area of about 5 km2 (1.9 sq mi). It will feed on any small creatures it can find including mammals, birds, snakes, lizards, beetles and scorpions. It perches on an eminence and watches and listens so as to detect moving prey before swooping down on its victim.<p>This owl is monogamous and forms a lifelong relationship. Breeding takes place in late winter and the nest is a scrape in a crevice or among rocks. Two eggs are laid and incubated by the female for about 31 days. The chicks are fed by both parents and leave the nest at about 20 to 35 days old, but remain reliant on their parents for several more months.
保护状况
The Pharaoh eagle-owl has a very large range and is reported as being abundant in at least part of the range. It faces no particular threats, and is therefore listed as Least Concern on the IUCN Red List.

Yungas Guan
Penelope bridgesi
Large guan with a long tail and red throat wattle. Dark brown overall with extensive white markings on wings. Unlike most other members of its genus, Yungas has dull grayish legs. Found in montane forests and edges. Listen for loud, harsh calls often given in a series. Restricted range in northwestern Argentina and southern Bolivia. Usually in pairs or small groups; often seen feeding at fruiting trees, but can be seen walking on the ground.
Wahlberg's Eagle
Hieraaetus wahlbergi
A small brown eagle with a slighter head and weaker beak than in larger brown eagles. A short crest gives the head a distinct squared-off look. In flight its crucifix-ilke shape is distinctive: straight-edged wings and a long straight-edged tail are most often held closed. Also occurs in pale and intermediate morphs, but dark, chocolate-brown coloration is the most common. Movements are complex, but it is mostly an intra-African migrant, breeding in the south (August to March) and occurring year-round farther north. Inhabits woodland, savanna, and farmland, hunting a broad range of vertebrate and insect prey both from perches and on the wing.
Glossy Black-Cockatoo
Calyptorhynchus lathami
Smaller brownish-black cockatoo of eastern Australia. Male fairly plain except for bright red tail panels. Female has blotchy yellow patches on neck and face and orange-red tail panels. Large bill used to feed on Allocasuarina and Casuarina seeds. The species is entirely dependent on these trees, and recently chewed seed-cones are good indicators of their presence. Usually observed in small groups rather than large flocks. Calls include drawn-out notes with a rougher, croakier tone than Red-tailed and Yellow-tailed Black-Cockatoos.
