Grassland Sparrow
Ammodramus humeralis
Small sparrow with a short tail found in grasslands including agricultural areas with grassy edges. Brownish gray above with heavy dark streaks and brownish wings, and plain gray-buff below. Note the short yellow eyebrow that does not reach beyond the eye. Usually sings a series of soft buzzy whistles from fence posts or shrubs.
识别特征
The grassland sparrow is a robust species with a large head and a short tail, with a total length of about 13 cm (5 in). The wings are short and the legs fairly long. The upper parts are brownish-grey streaked with black. The breast and flanks are greyish-buff or pinkish-buff and the underparts are dull white. There is a narrow white eye-ring, and a spot of yellow on the lores and another on the bend of the wing. The song is a high-pitched but thin series of plaintive phrases, "eee, telee, teeeee". This bird is similar in appearance to the yellow-browed sparrow, but that has more yellow on the face and the voice is quite distinct.

行为
A "secretive" bird, this species feeds on the ground and flits away into the vegetation if disturbed. It can be observed when singing from an elevated perch, and feeds out in the open in the early morning and late evening. The diet consists of grass and other seeds, and small insects are also eaten, particularly during the breeding season. The nest is cup-shaped and built on the ground, with a runway through the foliage leading to it.

Abyssinian Ground-Hornbill
Bucorvus abyssinicus
A huge ground-dwelling hornbill. Males have a mix of blue and red bare facial skin, while females have entirely blue facial skin. In flight, a large white patch is revealed in the wings. Found in savanna, grassland, and agricultural habitats, usually in pairs or small groups, walking on the ground. Breeds and roosts in trees. Similar to Southern Ground-Hornbill, but there is little overlap in range, and Abyssinian is easily separated by the blue facial skin. The call is a series of deep “boop” notes.

Crested Eagle
Morphnus guianensis
A huge, rare eagle, found in large swaths of mature lowland and foothill forests through much of Central and South America. Always rare and infrequently seen; any day with a Crested Eagle deserves a gold star. Light morph adults are dark gray above and whitish below with a gray head and breast and barred belly. Dark morph is very rare and is dark gray overall with white barring on belly. The similar Harpy Eagle (which does not have a dark morph) has a more contrasting black chest and lacks barring on the belly. Juvenile Crested Eagle is mostly white with darker wings; separated from Harpy Eagle by slightly smaller size and slimmer shape. Most often seen perched in the canopy of mature lowland forest, but occasionally soars.

Sabah Partridge
Tropicoperdix graydoni
Intricately-patterned partridge of tropical lowland rainforest. Uncommon and declining throughout its range. Brown with buff scaling, rusty bib, stippled black-and-white head pattern, and a pale throat. Forages in small flocks on the forest floor. Found at lower altitudes than other partridges in range and distinguished by pale ear patch and lack of rufous on the head. Song, often given as a duet, consists of loud, tremulous whistles followed by a series of up and down notes “weep! churrrrr…!”.
