Blackish-blue Seedeater
Amaurospiza moesta

分类信息
The blackish-blue seedeater is monotypic.<p>It and the other members of genus Amaurospiza were traditionally placed in family Emberizidae. (At that time, the family included the New World sparrows, which are now in their own family Passerellidae.) Since approximately 2008 they have been placed in their current family.

分布与栖息地
The blackish-blue seedeater is primarily found in southeastern Brazil and adjoining eastern Paraguay and northeastern Argentina. However, there are also scattered records further north in Brazil. It inhabits the undergrowth and edges of woodland and is especially partial to Chusquea and Guadua bamboo. In elevation it ranges from sea level to 1,600 m (5,200 ft).

行为
The blackish-blue seedeater's diet is primarily bamboo seeds, and it probably eats other seeds and insects as well. It forages singly or in pairs from the ground up to about 3 m (9.8 ft) above it.<p>Blackish-blue seedeaters in breeding condition or adults feeding young have been observed in April, August, September, November, and December. This suggests that breeding may not be seasonal but relies on the availability of bamboo seed.<p>The blackish-blue seedeater's song is "a pleasant warble" [1] and its calls sound like "psit" or "pix".

Common Newtonia
Newtonia brunneicauda
Energetic and pugnacious little plain-brown vanga. The eye is white, and the center of the chest usually orange. Madagascar endemic that is found in all types of forest. Constantly on the move through the mid-story, usually in pairs. Often joins flocks with vangas and other mid-sized birds. Song is an explosive, rollicking series of two-parted notes: “chi-pu, chi-pu, chi-pu….” Pale eye and paler overall coloration separate it from Dark Newtonia. Pale eye also separates Common Newtonia from the rare Red-tailed Newtonia. Similar to Archbold’s Newtonia, but without rufous around the eye.
Middle American Screech-Owl
Megascops guatemalae
Small, cryptically patterned, yellow-eyed owl of tropical lowland forest from Mexico to Panama. Tends to stay well hidden in the understory. Cannot be identified readily by sight, but it is the only screech-owl throughout most of its range and within its habitat. Song is a purring trill that can easily be mistaken for the purring of a toad or insect. Plumage varies from grayish brown overall to reddish.
Ecuadorian Cacique
Cacicus sclateri
Rare all-black bird found in rainforest east of the Andes, especially near forest-fringed lakes and rivers. Pale blue eye helps separate it from Solitary Black Cacique, which has a dark eye. Might also be confused with Red-rumped Cacique, which often conceals its rump with its wings. It has an amazing vocal repertoire, giving siren-like whistles, metallic squeaks, and catlike squeals, among other calls.
