White-throated Crake
Laterallus albigularis
Small marsh bird, very difficult to see as it creeps through dense grass. Far more easily heard: listen for a loud descending chatter that lasts several seconds. If you are lucky enough to spot one, look for the combination of rich rufous neck and sides of breast, whitish throat, and barred black-and-white flanks. Favors damp pastures and marshes, where it usually stays hidden but occasionally runs through open areas.
识别特征
The white-throated crake is 14 to 16 cm (5.5 to 6.3 in) long. Males weigh about 50 g (1.8 oz) and females 45 g (1.6 oz). The sexes are alike. Adults of the nominate subspecies have a white throat and upper breast and a rufous face, sides of the neck, and lower breast. Their crown, nape, and upperparts are olive brown. Their belly, vent, and undertail coverts are barred black and white. Subspecies L. a. cinereiceps has a gray face and L. a. cerdaleus has an entirely rufous head and throat.
分类信息
The white-throated crake was for a time treated as a subspecies of the rufous-sided crake (L. melanophaius). As a species in its own right, it has three subspecies, the nominate L. a. albigularis, L. a. cinereiceps, and L. a. cerdaleus.

分布与栖息地
The nominate subspecies of white-throated crake is found along the Pacific side of southwestern Costa Rica and Panama and through northern and western Colombia into western Ecuador as far south as El Oro Province. L. a. cerdaleus is found in northern Colombia and extreme northwestern Venezuela. L. a. cinereiceps is found from southeastern Honduras along the Caribbean slope of Nicaragua and Costa Rica and into Panama as far as Veraguas Province. The nominate subspecies has also occurred in Peru as a vagrant.<p>The white-throated crake inhabits a variety of both wet and dry landscapes including marshes, wet grassy fields and pastures, thickets, forest clearings, and the edges of watercourses and ponds. In elevation it ranges from sea level to 1,600 m (5,200 ft).

行为
The white-throated crake is generally sedentary but may relocate locally to higher ground during the rainy season.<p>The white-throated crake usually forages in cover but will move into the open at dawn and dusk and during rainy weather. Its diet includes insects, spiders, grass and sedge seeds, algae, and some small fruits.<p>The white-throated crake's breeding season varies geographically. It makes a sperical nest of woven grass stems and leaves with a side entrance, placed in a bush or grass tussock over water or ground. The typical clutch size is two to five eggs.<p>The white-throated crake makes an "[a]brupt, explosive descending trill or churr"; its alarm call is "a sharp 'chip'" note.

Swift Parrot
Lathamus discolor
Colorful migratory parrot with long red pointed tail. Breeds in Tasmania and migrates to southeastern Australia in autumn and winter. Found in a wide variety of forests, where its presence is largely dictated by flowering eucalypts on which it feeds. Adult bright green with red and yellow on face and a subtle blue-purple crown patch. In flight, shows bright red underwings and long red tail. Compare Scaly-breasted Lorikeet, which has shorter green-yellow tail. Calls include a sharp rattling as well as short, piercing squeaks.
Lemon-breasted Seedeater
Crithagra citrinipectus
A small gray-brown seedeater with a lemon-yellow rump, white tail tips, and a boldly marked face with pale patches (white to lemon-yellow) above and below the eye. The throat and upper breast are lemon-yellow in the male and buff in the female. Pairs and small flocks occupy savanna, grassland, and palm savanna, where the species is partial to Ilala Palm. It forages on the ground and in small shrubs and grass. The similar Yellow-fronted Canary is yellower, has a broader eyebrow, and lacks wingbars and the vertical dark stripe below the eye.
Hadada Ibis
Bostrychia hagedash
A large, bulky, gray-brown ibis with an iridescent green-purple gloss on the wings. It has a bicolored black-and-red bill and a white streak across the cheek under the eye. Pairs and small flocks occur in a variety of habitats including open country, wetland margins, and forest edge; they forages on the ground, digging, probing soft soil, and picking up invertebrates with their long bills. The frequently-heard call is one of the most characteristic sounds of Africa: a loud, raucous, trumpeting “ha-da-da” which gives the bird its name.
