Black-capped Tinamou (Crypturellus atrocapillus)

Full Issue

“…We identified the species by voice (ML 502296431) at a locality in northwest Pando, near Extrema, but never saw any individual there, so are unable to determine the subspecies based on morphology. Although subspecies atrocapillus may differ vocally ISSN-2513-9894 (Online) from garleppi (Cabot et al 2020), we are unable to detect any consistent differences between available recordings of both subspecies, and thus tentatively assign our observations to garleppi, which occurs in nearby Acre, Brazil. Black-capped Tinamou is known to occur <5 km away from our locality in Peru, making occurrence in Pando unsurprising.…”

Noteworthy records of birds from Pando including two new species for Bolivia

“…We identified the species by voice (ML 502296431) at a locality in northwest Pando, near Extrema, but never saw any individual there, so are unable to determine the subspecies based on morphology. Although subspecies atrocapillus may differ vocally from garleppi (Cabot et al . 2020), we are unable to detect any consistent differences between available recordings of both subspecies, and thus tentatively assign our observations to garleppi , which occurs in nearby Acre, Brazil.…”

Automated audio recording as a means of surveying tinamous (Tinamidae) in the Peruvian Amazon

“…Both species are uncommon at Los Amigos (eBird, 2017; personal obs. ), are known to have affinities for brushy edge habitats that were located away from most of the recorders (Anjos, 2006;Cabot et al, 2020), and were entirely absent from the camera trap dataset. Therefore, we suspect that their lack of detection indicates true absence from the dataset rather than poor class performance.…”
