White-eared Conebill
Conirostrum leucogenys
This unmistakable warblerlike bird is fairly common in forests and edges from Panama to Colombia and Venezuela. Males are pale pearly-gray below and richer blue-gray above with a dark cap, a white cheek, and chestnut undertail coverts. Females are grayish above and pale grayish-buff below. Note the sharply pointed bill. Almost always found in pairs, usually in the canopy of forests and edges in lowlands, up to around 800 m. Sometimes joins mixed-species flocks.
识别特征
The White-eared conebill is small (7g) bird. Subspecies are similar in appearance across their range. Adult males have a blue back, wings, and tail, and a light blue sometimes greyish underpart with a rufous undertail covert. They have a black crown, face, and lores, and a white cheek. Immature males are similar but have a less bold black colouring on the face and crown. Females are more subtly coloured, with a lighter blue back, crown, nape, and tail, with the primaries being olive coloured and the breast, belly, flanks and face being yellow. Both sexes have greyish-black legs, silver bills, and brown eyes.
分类信息
The White-eared conebill was described by French ornithologist Frédéric de Lafresnaye in 1852. It was originally described by de Lafresnaye as a dacnis, and placed in the genus Dacnis, before later being moved into the defunct genus Ateleodacnis, and then later into its current genus Conirostrum with the rest of the conebill species'. There are currently three recognized subspecies:

行为
Like other conebills, the White-eared conebill mainly eats insects, foraging usually in the canopies of trees. It has also been known to join mixed species flocks but not to the same frequency as other relatives like the Blue-backed conebill and the white-browed conebill.

Ochre-rumped Bunting
Emberiza yessoensis
Secretive bunting of reedbeds and grassy fields. Not as social as Reed and Pallas's Buntings and doesn't expose itself as often; usually solitary, sticking to dense clusters of fallen vegetation near the ground. Breeding male is unique in the region for his entirely black head. Adult female and nonbreeding male have a ghost of the coal-black head; head patterning can be evocative of Meadow Buntings, which are much larger. Ochre rump is visible in all plumages and is diagnostic, but it can be difficult to see.
Diademed Tanager
Stephanophorus diadematus
Large blue tanager with a short strong bill. Unmistakable; mostly blue with a black mask, a red crest, and a white crown. Found at the edge of montane forests including Araucaria forests, woodlands, parks, and gardens. The song is melodious and rich.
Black-and-white-casqued Hornbill
Bycanistes subcylindricus
Big, spectacular, black-and-white hornbill. The males have a large black-and-white bill, and females a much smaller all-dark one. In flight, shows a broad white patch at the back of the wing and a black tail with white sides. Found in thick forest and adjacent areas of lush woodland and cultivation. Usually in pairs or small groups. The loud calls are honking and yapping notes that are often given in a quick series. Similar to White-thighed and Brown-cheeked Hornbills, but has a black center to the tail, and the wingtips are black. Also has a darker bill and casque than those species.
