White-mantled Barbet
Capito hypoleucus
Endemic to northern Colombia. Glossy black above and off-white below with a vague brown breast band. Look for the stout bill and patch of red on the forehead. Sexes similar. The namesake white mantle can be difficult to see, as these birds tend to stay high in the canopy of tall forest. Usually in pairs, which follow mixed-species flocks.
识别特征
With the division of toucan barbet, the white-mantled barbet is perhaps the largest of the New World barbets, rivaled only by the scarlet-banded barbet. with an average length of 19 cm (7.5 in), males and females respectively weigh an average of 74.6 g (2.63 oz) and 67.4 g (2.38 oz). The bird has black upperparts with narrow pale lines on the nape and scapulars. These lines are not easy to see because the bird is mostly observed higher up in the canopy of tall trees. The forehead and crown are red. The bird's underparts are white with a slight yellowish wash and a flush of cinnamon on the breast. They eyes are red, the large, chunky bill is yellowish, and the legs and feet are greenish-grey. Females have a black spot at the base of the lower mandible.
分类信息
This species was first formally described in 1897 by English ornithologist Osbert Salvin, based on a sample collected by Antwerp Edgar Pratt in Antioquia Department. The species name is derived from the Latin capito - big-headed, and the Ancient Greek hupo - beneath, and leukos - white.<p>Three subspecies are recognized:

分布与栖息地
The white-mantled barbet is found in the Middle Magdalena Valley of Colombia at altitudes between 200 and 1,800 m (660 and 5,910 ft).<p>It is a bird of the tropical zone, inhabiting humid forests on montane slopes, forest patches with a mosaic of pastures, secondary forest, and plantations mixed with fruiting trees.

行为
These barbets typically forage in pairs or family groups, and may follow mixed-species feeding flocks. They mostly stay in the forest canopy, but come down and into the open at fruiting trees such as mango and Cecropia.<p>The white-mantled barbet population is declining, primarily due to habitat loss. The IUCN Red List classifies the species as vulnerable. The Red Book of the Birds of Colombia, noting that the species has lost 60% of its historic habitat and that that habitat continues to decrease, lists the bird as endangered. The primary causes of this habitat loss are illicit cultivation, overuse of insecticides, and small-scale gold mining.

Red-faced Barbet
Lybius rubrifacies
Chunky, medium-sized black barbet. There is red on the face, and the bottom part of the wing has white edging. Found locally in woodland, cultivated areas, and gallery forest. Usually in pairs or small groups. The call is an unmusical duet of low, rasping calls. Similar to Black-billed Barbet, but not known to overlap in range, and easily separated by lack of red on the throat or white edges to the top part of the wing.
White-winged Tapaculo
Scytalopus krabbei
Described to science in 2020, this tapaculo was long overlooked due to its similarity with other species. It ranges in high elevation cloud forest along the east slope of the Andes in northern and central Peru. Plumage is mainly gray with brownish rear parts that are faintly barred. It has a few white feathers on the shoulder, which distinguishes it from all other tapaculos in Peru, but this feature is very hard to see in the field. Female is browner than male. Currently it is known from only a few sites, but will likely be found more widely now that its vocalizations are known. Song is a steady series of buzzy calls; the first few notes may be slower paced and higher pitched. Also gives a quick burst of sharp notes, repeated every few seconds. Stays low and is usually hard to see.
Summer Tanager
Piranga rubra
Large tanager with a hefty bill. Adult males are completely red; immature males are dull yellow-olive with blotchy patches of red. Females are variable in color, ranging from pale dull yellow to brighter orange. Can be confused with female Scarlet Tanager; Summer has a longer, paler bill and less contrast between wing and body color. Also compare with dustier-looking, stouter-billed Hepatic Tanager. Breeds in mature forests, favoring mixed deciduous and pine in the southeastern U.S. and riparian corridors in the western U.S. and northern Mexico. Extensive winter range from Mexico to Bolivia, where it can be found in any wooded area. Often gives a short, descending rattle “pit-a-tuck.”
