アリプアナマユアリサザイ Herpsilochmus stotzi

Recently described Amazonian antwren. Males are gray with a bold white eyebrow and a black crown, wings, and tail. Females have a pale rusty forehead patch. Occurs primarily in white sand forest, but also in humid forest, where it forages in the canopy, often with mixed-species flocks. The song is a rolling trill. The similar Predicted Antwren has a longer song; males have more black on the back and females have a more rusty forehead.
