Amazonian Black-Tyrant
Knipolegus poecilocercus
A rarely-encountered medium-sized dark flycatcher, most often found in flooded forests along rivers. Both males and females similar to the related Riverside Tyrant, but that species prefers more open habitat. Male Amazonian Black-Tyrant is shiny-black, smaller and glossier than male Riverside. Female Amazonian are warm brown with streaked underparts, considerably warmer in coloration than female Riverside. Notably quiet for a flycatcher.
识别特征
The Amazonian black-tyrant is a medium-sized, dark flycatcher. It is usually located in flooded forests along rivers. The species encounters sexual dimorphism. Males are darker, smaller, and glossier than male riverside tyrants. Females are brown with a streaked abdomen. Amazonian black-tyrants are known for being quieter than other flycatchers. The riverside tyrant and Amazonian black-tyrant look similar; however, the riverside tyrant is generally noticed more in open riverine settings.
分类信息
The scientific name for the Amazonian black-tyrant is Knipolegus poecilocercus. It was first scientifically described by August von Pelzeln in 1868 in Zur Ornithologie Brasiliens: Resultate von Johann Natterer Reisen in den Jahren 1817 bis 1835. The Amazonian black-tyrant is a part of a monotypic bird family. These birds can also be referred to as Viudita amazonica; in Brazilian Portuguese, they are referred to as the pretinho-do-igapó.

保护状况
Despite a decreasing population trend, the Amazonian black-tyrant is currently classified as "Least Concern" on the IUCN Red List of Threatened Species. This species occupies a range considered to be large, meaning how it does not meet the criteria for being classified as "Vulnerable" by the Red List; the population size of the species is also not believed to meet the criteria for a listing of "Vulnerable," although the number of Amazonian black-tyrants is unknown. This species' breeding range covers an area of 4,960,000 square kilometers. Amazonian black-tyrants are distributed across multiple countries.

Streaked Rosefinch
Carpodacus rubicilloides
Large, bulky rosefinch. Male is pinkish-red below with a streaked brown back. Female is streaky dust-brown all over. Both sexes are very similar to Great Rosefinch; look out for dark streaking on the back in both, as well as smaller white, more solid-looking white spots on the underparts of the male. Breeds in dry open expanses with sparse scrubby vegetation at around 3700-5200 meters. Winters in similar habitat, sometimes descending to lower elevations. Song consists of somewhat hoarse whistled notes. Gives a sparrow-like “chweep” and a shorter “chep.”
Predicted Antwren
Herpsilochmus praedictus
Recently described Amazonian antwren. Males are gray with a bold white eyebrow and a black crown, wings, and tail. Females have white spots on a black crown and a rusty forehead. Found in humid forest, including seasonally flooded forest along big rivers and white sand forest, foraging from the middle levels to the canopy. Usually accompanies mixed-species flocks in the canopy. The song is a soft rolling trill. The rather similar male of the Aripuana Antwren has less black on the upperparts, and females have a paler forehead; Aripuana’s song is similar, but with fewer notes.
House Crow
Corvus splendens
A slender, blackish medium-sized crow with a long bill. The grayish nape and sides form a paler collar that contrasts with the glossy black body. Primarily a scavenger, feeding on leftover rubbish from humans. Found in a wide range of habitats mostly around human habitation. Their call is a loud and harsh “kaa kaa kaa.”
