Cinnamon Teal
Spatula cyanoptera
Small duck with chalky-blue patches on the upperwing (visible in flight). Breeding males unmistakable with rich reddish-brown color overall. Females are buffy-brownish overall and intricately patterned. Look for rather plain face and longer, more spatulate-shaped bill than Blue-winged Teal. Widespread and fairly common throughout western North America and South America, as far south as Tierra del Fuego. Usually found in shallow wetlands or marshes, where it can occur in pairs or flocks, sometimes mixed with other species of ducks.
识别特征
The adult male has a cinnamon-red head and body with a brown back, a red eye and a dark bill. The adult female has a mottled brown body, a pale brown head, brown eyes and a grey bill and is very similar in appearance to a female blue-winged teal; however, its overall color is richer, the lores, eye line, and eye ring are less distinct. Its bill is longer and more spatulate. Male juvenile resembles a female cinnamon or blue-winged teal but their eyes are red. They are 16 in (41 cm) long, have a 22-inch (560 mm) wingspan, and weigh 14 oz (400 g). They have 2 adult molts per year and a third molt in their first year.

分布与栖息地
Their breeding habitat is marshes and ponds in western United States and extreme southwestern Canada, and are rare visitors to the east coast of the United States. Cinnamon teal generally select new mates each year. They are migratory and most winter in northern South America and the Caribbean, generally not migrating as far as the blue-winged teal. Some winter in California and southwestern Arizona. Two subspecies of cinnamon teal reside within the Andes of South America. The smaller sized S. c. cyanoptera is widespread within low elevations (<1000m) such as the coast of Peru and southern Argentina, whereas the larger size subspecies S. c. orinomus occupies elevations of 3500–4600 meters in the central Andes.

Marabou Stork
Leptoptilos crumenifer
This huge, macabre-looking stork has a massive dagger-like bill and naked pink head and neck that appear severely sunburned. A white ruff and loose inflatable skin on the neck add to its odd appearance. It soars effortlessly at great heights searching for food; note its white belly in flight. Marabous are equally content in wetlands or in dry bush; they are most frequently encountered lurking near carrion, as they attend kills of major predators and will opportunistically snatch scraps. They also readily scavenge around humans and waste dumps.
Cape Canary
Serinus canicollis
Rather plain seedeater with a gray nape, yellow underparts, and olive-green back. Found in fynbos, woodland, grassland, and gardens. Usually in small flocks. Distinctive call is a short, high-pitched trill, often given in flight. Song is a frantic, warbled jumble of notes. Separated from similarly sized seedeaters by gray nape and lack of facial markings.
Pacific Robin
Petroica pusilla
A small, attractive robin with a bright crimson chest and belly. Varies across range, but male is mostly dark above and on head except for bright white forehead and pale wingbar. Base of undertail white. Female mostly brown above but red below. Generally unique and unmistakable within range. Inhabits forested areas at a range of elevations. Voice varies across range but is generally a mix of high-pitched tinkling, sweet high-pitched tweeting, and whistling.
