Podrobnosti k pozorování
This bird has been confirmed as Bornean Swiftlet by James Eaton. James has recently published a new paper on Bornean Swiftlet identification, which can be read here… https://www.researchgate.net/publication/377077594_Citizen_science_and_dodgei_records_revisiting_the_identification_and_distribution_of_Bornean_Swiftlet According to this paper, the key feature that separates Bornean Swiftlet from Plume-toed Swiftlet is the dull brown cap that is scarcely discernible from the mantle and face, creating an appearance that is overall mostly uniform. In contrast, Plume-toed has a distinct, dark glossy-blue cap that contrasts with the browner, less glossy rest of the face. These photos are screenshots from a video taken by Richard Aracil as pat of the University of Montana avian life history study.
