Guianan Warbling-Antbird
Hypocnemis cantator
Small antbird; most easily identified by conspicuously striped head, contrasting tawny flanks, and sluggish behavior. Most common in disturbed and secondary forests, at forest edges, and near treefall gaps. Almost always found in pairs and within a few meters of the ground; sometimes follows army ants and understory mixed-species flocks. Very vocal and not shy but can be hard to see well; often scolds observers while darting from perch to perch.
Identification
The Guianan warbling antbird, or Guianan antwarbler, (Hypocnemis cantator) is an insectivorous bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, French Guiana, Guyana, Suriname, and Venezuela.
Taxonomy
The French polymath Georges-Louis Leclerc, Comte de Buffon described the Guianan warbling antbird in his Histoire Naturelle des Oiseaux in 1779. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Buffon did not include a scientific name with his description but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Formicarius cantatar in his catalogue of the Planches Enluminées. The specific name is from the Latin cantator "a singer". The present genus Hypocnemis was introduced by the German ornithologist Jean Cabanis in 1847.<p>The Imeri, Peruvian, yellow-breasted, Rondonia and Spix's warbling antbird were all formerly treated as subspecies of the Guianan warbling antbird. A study published in 2007 found that there were significant vocal differences as well a small plumage differences between the taxa and they are now all treated as separate species. As presently defined, the Guianan warbling antbird is monotypic, although the subspecies notaea sometimes has been recognized.<p>Its conservation status has been assessed as near threatened.

Other Birds
Fulvous-faced Scrub-Tyrant
Euscarthmus fulviceps
Very small grayish-brown flycatcher, with brighter orangey color on the face and forehead. Occurs in dry areas and pastures with scattered trees and bushes where it mostly forages near the ground and is typically difficult to spot. It is very noisy, emitting squeaky “plee-plit-irick” calls, sometimes in a duet. Occurs in western Ecuador and northwestern Peru.
Fischer's Sparrow-Lark
Eremopterix leucopareia
A small, compact, finch-like sociable lark that can be both resident and nomadic, although movements are poorly understood. The sexes differ in plumage: the distinctive male has a tawny crown and nape, bold pale ear-patches, and otherwise dark face and throat that stretch as a line down the belly to the vent; the dull streaky female has a buffy eyebrow and a dark breast and belly patch. Immature is similar to the female. Small-to-medium-size flocks prefer semi-arid grassland and bare fields. Compare to Chestnut-backed Sparrow-Lark, in which both sexes are darker and more contrasting than Fischer’s Sparrow-Lark.
Black-faced Monarch
Monarcha melanopsis
A slim songbird with rather long tail and substantial bill. Gray above, rufous below, with gray head, black forehead and throat. Juvenile lacks black in face. In all plumages, small white crescent in front of eye. Often perches horizontally, slightly raising tail. Inhabits wetter forested areas along eastern coast of Australia, where it forages slowly for insects in foliage.
