Description
Please fill in a detailed description of the bird(s). Original field description preferred (i.e. without help of literature). Include features such as size, structure, posture, colours, patterns, behaviour, call and song. Describe characters such as head, bare parts, upperparts, underparts, wing and tail (attach extra page if needed).
DESCRIPTION
A Hemitriccus tody-tyrant with oval nostrils (suggesting a member of the ‘Snethlagea’ group, comprised of H. minor, H. spodiops, and H. cohnhafti). Drab olive overall with weak ‘flammulations’ below on a yellower belly, weak wingbars and secondary edges yellowish. Iris pale gray. Present in Guadua bamboo (some of which was flowering, dying, and collapsing). Voice was primarily a short, slightly rising-falling “breeu”, not like voices of any Hemitriccus known already in Peru, nor like H. spodiops, but somewhat similar to some vocalizations of H. minor. See attached photos of two individuals (one just collected, one a video capture of a bird that was subsequently collected).
Note oval nostril shape, indicative of a ‘Snethlagea’.

Did you have previous experience with the species? XNo
Do you have experience with similar species? XYes
If you answered yes please elaborate
I have encountered Hemitriccus spodiops both in Peru and Bolivia, which differs in voice, elevation, and preferred habitat. I do not know H. minor in life, but H. cohnhafti differs from that species in voice and preferred habitat as well. The only other known locality (the type locality) for H. cohnhafti is just over the border in Acre, Brazil. Two of the authors who described H. cohnhafti (A. Aleixo, K. Zimmer) listened to my recordings of the Madre de Dios birds and confirmed the identification.
Are confusing species excluded? XYes
If you answered yes please explain how confusing or similar species were excluded
