Greater Prairie-Chicken
Tympanuchus cupido
Plump, chickenlike bird found in grasslands. Body and wings entirely barred brown with paler buffy throat. In spring, males gather at display site and dance to attract females: look for them hunched over with earlike feathers protruding from the head and yellowish-orange skin exposed on the neck. Inconspicuous and difficult to find away from display sites. Separate from Lesser Prairie-Chicken by range; averages slightly darker and larger than Lesser. Darker than Sharp-tailed Grouse with more heavily barred sides and belly; rounded tail.
识别特征
Adults of both sexes are medium to large chicken-like birds, stocky with round wings. They have short tails which are typically rounded. Adult males have orange comb-like feathers over their eyes and dark, elongated head feathers that can be raised or lain along neck. They also possess a circular, un-feathered neck patch which can be inflated while displaying; this, like their comb feathers, is also orange. As with many other bird species, the adult females have shorter head feathers and also lack the male's yellow comb and orange neck patch. Adults are about 43 cm (17 in) long, and weigh between 700–1,200 g (25–42 oz). The greater prairie-chicken has a wingspan range of 69.5–72.5 cm (27.4–28.5 in).

保护状况
The greater prairie-chicken was almost extinct in the 1930s due to hunting pressure and habitat loss. In Illinois alone, in the 1800s, the prairie-chicken numbered in the millions. It was a popular game bird, and like many prairie birds, which have also suffered massive habitat loss, it is now on the verge of extinction, with the wild bird population at around 200 in Illinois in 2019. It now only lives on small parcels of managed prairie land. Throughout North America, it is thought that their current population has declined severely, to approximately 500,000 individuals. In May 2000, the Canadian Species at Risk Act listed the greater prairie-chicken as extirpated in its Canadian range (Alberta, Saskatchewan, Manitoba, Ontario). It was again confirmed by the Committee on the Status of Endangered Wildlife in Canada in November 2009. Nonetheless, sightings and encounters continue to occur in the south-central regions of Alberta and Saskatchewan, along with southern Ontario, where sightings are extremely rare.<p>In states such as Iowa and Missouri that once had thriving prairie-chicken populations (estimated to be hundreds of thousands), total numbers have dropped to about 500. However, the Missouri Department of Conservation has started a program to import prairie-chickens from Kansas and Nebraska in the hopes that they will be able to repopulate the state and increase that number to 3,000.<p>Central Wisconsin is home to approximately 600 individuals, down from 55,000 when hunting was prohibited in 1954. Though this area was predominately spruce and tamarack marsh before European settlement, early pioneers drained the marshes and attempted to farm the poor soil. As the prairies to the south and west were lost to agriculture and development, and the southern half of Wisconsin was logged, the prairies spread northward into the abandoned farmland. Today, over 30,000 acres are managed by the Wisconsin Department of Natural Resources as greater prairie-chicken habitat. Birdwatchers travel from around the world to visit Wisconsin in April for the Central Wisconsin Prairie Chicken Festival, started in 2006 by Golden Sands Resource Conservation & Development Council, Inc.

Roadside Hawk
Rupornis magnirostris
Well-named, the common roadside hawk in tropical lowlands of East Mexico and Central and South America. Often seen on wires, phone poles, posts out in fields. Adult has staring pale eyes, streaked breast contrasting with barred belly. Immature streaked below, much like many other immature hawks, but its tail has broad and fairly even bands. Flies with rather quick, stiff wingbeats, recalling a Red-shouldered Hawk or an Accipiter; noisy flight display mainly in late winter-spring.
Southern Scrub-Robin
Drymodes brunneopygia
Long-legged songbird found in semi-arid parts of southern Australia. Grayish above, paler gray below, with faint wingbars and long tail, often flicked upward. Very subtle dark mark through the eye and cheek. Usually seen running around on the ground in open woodland, although male also sings from higher perches. Main call is a repeated three-note rising whistle, "chip-dee-deee," but also makes rough, buzzy alarm calls.
Velvet Scoter
Melanitta fusca
Large scoter, with distinctive white patch on wing. Dark chocolate-brown overall; males are darker than females and have small white mark under eye. Note bill pattern: mostly yellow with a dark knob on top and a subtle pinkish tip. Females have two rounded white patches on face. Breeds on ponds, lakes, or rivers in woodland or tundra across much of northern Europe. Winters mainly in coastal waters, sometimes in large flocks. Occasionally found on large inland lakes during migration. Dives frequently, feeding on mollusks and crustaceans.
