Baird's Sparrow
Centronyx bairdii
One of North America's most sought-after sparrows due to its small breeding range and secretive habits. Breeds in extensive tall grasslands; winters in similar grassy habitats. Pale tan overall with crisp black streaking on breast. Warm buffy face is brightest to the rear of the eyebrow and broken up by thin black markings. Easy to see when perched, singing its high-pitched tinkling trill; otherwise shy and difficult to locate. Population is declining due to development of prime grassland breeding habitat.
Identification
The Baird's sparrow can be identified as a small brown streaked sparrow. Their faces are a yellow-brown color featuring subtle black markings. These birds have a narrow band of brown streaks on their chests. This species can be distinguished from others by its unique broad ochre central crown stripe. Juveniles exhibit similar coloration but often have more streaking. Adult size is comparable for both males and females, no sexual dimorphism is exhibited. Adults are generally about 12 cm (5") and weigh 17-21 g (½ to ¾ oz); their wingspan is usually around 23 cm (9").<p>They are larger than LeConte's sparrow and do not exhibit orange coloration on their faces. They exhibit very similar coloration and patterning to Henslow's sparrow but do not have green coloration on their faces. The Savannah sparrow is more heavily streaked and has an extra white marking on its head.
Taxonomy
The Baird's sparrow was first described in North Dakota in 1843 by John James Audubon, and another record of this species was not made for 29 years following its discovery. It was named after the American naturalist Spencer Fullerton Baird.

Range and habitat
The Baird's sparrow migrates from its summer breeding habitat, the tall grass prairies of north central United States and South Central Canada, to spend winters in northern Mexico and the southern tip of the United States near Texas. Due to this migratory behavior, they may be spotted all across the Midwest portion of the United States during migratory seasons, but most frequently can be found in North Dakota, South Dakota, Minnesota, Montana, and Canada during the summer.<p>This species of sparrow resides in grassland habitats. These birds rely on the (now diminishing) tallgrass prairies, mixed grass prairies, and moister fescue prairies of northern United States and southern Canada. The dwindling status of this habitat puts many animals whose lifestyles rely on these ecosystems in peril. Land featuring woody vegetation and cultivated land is generally not a suitable environment for Baird's sparrows to thrive in.

Other Birds
Stripe-headed Sparrow
Peucaea ruficauda
Fairly common and conspicuous sparrow of dry, scrubby woodlands and brushy fields in tropical lowlands and foothills. Usually in small groups, which keep in touch with squeaky chattering calls. Often seen perched on fences. Bold head pattern is distinctive, with big black mask, bold white eyebrow, and blackish crown. Southern populations have variable dusky mottling on the breast.
Bat Hawk
Macheiramphus alcinus
An acrobatic, swift-like raptor with angular wings and a massive gape; capable of snatching prey from the air and devouring it in a flash while still on the wing. Dark with varying amounts of white on the underside; African birds have patchy white throughout the underparts, while white is restricted to the throat and lower belly on New Guinean birds and solely to the throat in Southeast Asian birds. Inactive during the day; hunts at dawn and dusk, and occasionally into the night if light is sufficient. Generally uncommon and localized, most reliably encountered near large bat roosts in forested areas, but can also be seen over open forest, fields, and fringes of habitation.
Green-fronted Hanging-Parrot
Loriculus tener
A very small, thick-set, stub-tailed parrot. Entirely green with a small red throat patch. Female has a light blue facial crescent. In flight, bright blue underwing is diagnostic. Resident in lowland forest, most often seen in flight. Similar to Finsch’s Pygmy Parrot but much brighter, with vibrant green coloration and, in flight, a stronger blue underwing. Commonly gives a very high-pitched repeated “tse-tse-tse” on the wing.
