Blue-eyed Ground Dove
Columbina cyanopis
Stunningly beautiful dove that has only recently been rediscovered. Cinnamon-colored overall but paler below. Note the conspicuous dreamy blue eyes and blue wing spots. Now only known from one location in Minas Gerais, Brazil, where it occurs in open savanna and grasslands on white sands and forages in pairs on the ground. Song is a repetition of soft notes: “wah-wha-wha…”

分类信息
The blue-eyed ground dove was for a time placed in the monotypic genus Oxypelia. That genus was merged into Columbina by the 1960s. Some plumage features set it apart from other Columbina species and more closely resemble those of the blue ground dove (Claravis pretiosa). The blue-eyed ground dove is monotypic.

There are historical records of specimens from Mato Grosso in the early 1800s, São Paulo in 1904, and Goiás in the early 1940s.<p>The species was rediscovered in 2015, and about 27 individuals among the only known population were left in 2017.

Wedge-tailed Eagle
Aquila audax
A very large, dark eagle with massive beak; often conspicuous due to large size. In flight, identified by very long diamond-shaped tail. Soars high, occasionally in groups, often over mountainous terrain. Frequently feeds on roadkill. Perches on telephone poles and dead trees. Young birds are more golden, and get progressively darker with age.
Pink-headed Warbler
Cardellina versicolor
Unmistakable small warbler of highlands in Guatemala and Chiapas. Favors humid conifer forest, pine-oak forest, and adjacent brushy areas; locally fairly common to scarce. Usually in pairs, foraging at all levels, often moving with mixed-species feeding flocks. Red overall with silvery-pink head and breast and dark wings and tail. No similar species.
Kori Bustard
Ardeotis kori
A massive, long-legged, terrestrial bustard with a black-and-white checkered pattern on the wing bend. It is conspicuous and encountered regularly in semi-arid shrubland, grassland, and savanna. Singles and pairs march slowly and purposefully, feeding on plant matter, large insects, and small vertebrates. Flies low, flapping with slow shallow wing beats. The males display in loose leks by puffing out their throat plumes and cocking their tails. Similar Arabian Bustard is smaller than Kori Bustard and has white and black checkered pattern at wing bend.
