Solutions to the mysteries on "Birds of Bolivia 2.0"
by Sjoerd Mayer
Sounds: Unidentified Hummingbird
- 1 - This is song of Golden-tailed Sapphire Chrysuronia oenone.
Solved by Daniel Lane in February 2005.
Sound: Unidentified Hemitriccus Tody-Tyrant Hemitriccus sp.
- This is Sulphur-bellied Tyrant-Manakin Neopelma sulphureiventer.
Solved by Daniel Lane in November 2004.
Sound: Unidentified Tyrant Flycatcher
- 2 - these are calls of Russet-crowned Warbler
Basileuterus coronatus. Solved by Sebastian Herzog, who also made the recording.
Sounds: Unidentified bird species (at the end of
the families list, before the Monkeys).
- 2 - this is of course the song of Black-winged
Ground-Dove Metriopelia melanoptera!
Solved by Niels Krabbe.
- 3 - almost certainly calls of Peruvian
Treehunter Thripadectes scrutator.
Obviously, something went wrong in the communication
between Juan Mazar Barnett (who made the recording) and
me, because it now turns out that Juan saw that the bird
was a Thripadectes Treehunter,
and later from his field notes concluded that it must
have been Peruvian T. T. scrutator ("the
bird was uniformly rufous-chestnut and more importantly
had an unstreaked back"). The altitude (3200 m) is another
indication that it
was this species.
- 5 - probably a Conebill Conirostrum
species (Niels Krabbe). Blue-backed Conebill Conirostrum sitticolor maybe? (Sjoerd)
- 6 - maybe the final trill of song of Common Bush-Tanager Chlorospingus ophthalmicus?
July 2004.
- 7 - probably song of Rusty Flowerpiercer Diglossa sittoides.
Solved by Sjoerd in April 2006.
- 8 - calls of Smoke-colored Pewee Contopus fumigatus. Solved by
Daniel Lane in May 2005.
- 9 - probably the frog Telmatobius yuracare.
- 10 - calls of Masked Trogon Trogon personatus. Solved by
Daniel Lane in November 2004.
- 11 - almost certainly Tufted Tit-Tyrant
Anairetes parulus. Solved by Niels Krabbe.
- 12 - probably Gray-breasted Wood-Wren
Henicorhina leucophrys. Solved by Bennett Hennessey.
- 13 - almost certainly Bar-bellied Woodpecker
Veniliornis nigriceps. Solved by Sebastian Herzog, who noted the similarity to
his own certain recording of that species, and then saw in his field notes that he
saw a male of the species in top of a tree right after the mystery recording.
- 15 - song of Ochre-breasted Antpitta Grallaricula flavirostris.
Solved by Daniel Lane in May 2005.
- 16 - calls of White-throated
Antpitta Grallaria albigula of course (compare
to the last recording under that species). Solved by
Niels Krabbe.
- 17 - probably calls of Azara's
Spinetail Synallaxis azarae. Solved by
Niels Krabbe.
- 18 - probably call of Pale-edged Flycatcher Myiarchus cephalotes.
Solved by Daniel Lane in May 2005.

Solved by Sebastian Herzog (who also made the recording).
- 20 - vocalizations of Gray-breasted Wood-Wren Henicorhina leucophrys.
Solved by Daniel Lane in May 2005.

Solved by Bret Whitney.
- 25 - sounds to me suspiciously like song of Sooty Antbird Myrmeciza
fortis from Ecuador!
- 26 - almost certainly a Tolmomyias flycatcher, and probably a
Yellow-olive Flycatcher T. sulphurescens
(Jonas Nilsson (andeanbirding@yahoo.com)).
- 28 - melody and "sound quality" are very much like
Cinereous Mourner Laniocera hypopyrrha.
Maybe a young bird? Solved by A. Bennett Hennessey.
- 29 - maybe calls of White-shouldered Antshrike Thamnophilus aethiops?
- 30 - probably calls of Pale-legged Hornero Furnarius leucopus.
Solved by Daniel Lane in May 2005.
- 31 - song of Spotted Puffbird Bucco tamatia.
- 33 - calls of Common Tody-Flycatcher Todirostrum cinereum. Solved by
Joe Tobias (joetobias22@hotmail.com) in July 2004.
- 35 - the song of the newly described Cryptic Forest-Falcon Micrastus
mintoni! (see: Whittaker, Andrew: "A new species of Forest-Falcon (Falconidae:
Micrastur) from southeastern Amazonia and the Atlantic rainforest of Brazil", Wilson Bulletin 114(4): 421-445,

Photos: Unidentified Black-Tyrant Knipolegus sp.
- Mark Pearman (mpearman@infovia.com.ar) assured me that this is a female
White-winged Black-Tyrant Knipolegus aterrimus ("The mystery Knipolegus looks fine for a
female aterrimus, and I think it is too large to be anything else").
