CD-ROM: Birds of Venezuela
Errata list, by Peter Boesman
(last update 30 December 1999)
On the CD-ROM a number of recordings were designated with a less than 100% certainty figure. It can be expected that some of these were not correctly identified. Even among those marked with 100% there can be some errors. We have tried our best to prevent any of those errors, but well, here we go:
Grey-bellied Hawk Accipiter poliogaster Example 1 and 2 (certainty 80%): This vocalisation sounds quite like Bicoloured Hawk A. bicolor. Although the bird did not seem to have any rufous thighs, the rarity of A. poliogaster in Venezuela (and elsewhere) suggests caution with these recordings.
Black-banded Woodcreeper Dendrocolaptes picumnus. Example 2 (certainty 90%): this could also be a call of Buff-throated (Cocoa) Woodcreeper Xiphorhynchus (guttatus) susurrans.
Black-throated Spinetail Synallaxis castanea. Example 1: This species and Caracas Tapaculo Scytalopus caracae have confused me for quite some time: they occur in exactly the same habitat and one seems to come to play-back of the other species. I now am quite sure example 1 is the song of S. caracae .
Rufous-backed Spinetail Cranioleuca vulpina. Example 1 belongs to the recently split Cranioleuca vulpecula of river islands in the Amazon and its tributaries.
Lineated Foliage-gleaner Syndactila subalaris. The rather strange vocalisation of example 1 and 2 (certainty 90%) was from a bird which looked like an immature S. subalaris. Streak-capped Treehunter Thripadectes virgaticeps looks rather similar though, and vocalisation is indeed rather Treehunter-like. After comparing with some recordings from the Ecuadorian Andes I now believe these recordings are from T. virgaticeps (which is equally rare in Yacambu NP: none of both species is on the NP checklist of Goodwin and Lentino) .
Ash-winged Antwren Terenura spodioptila. Example 1 (certainty 80%): this is White-lored Tyrannulet Ornithion inerme (this is an editing error rather then an identification error, sorry for that)
Scale-backed Antbird Hylophylax poecilonota. Example 1 (certainty 80%): this is most probably Grey Antwren Myrmotherula menetriesii. Example 2 (certainty 90%): this is most probably Wing-banded Antbird Myrmornis torquata.
Northern White-crowned Tapaculo Scytalopus atratus. All examples (certainty 80%) most probably are from Unicoloured Tapaculo Scytalopus (unicolor) latrans
.Venezuelan Tyrannulet Zimmerius improbus. I am checking on these vocalisations. On hold.
Yellow-olive Flycatcher Tolmomyias sulphurescens. Example 1 (certainty 80%) and example 2 (certainty 90%). These vocalisations are most probably of Painted Tody-Flycatcher Todirostrum pictum.
Tropical Peewee Contopus cinereus. Example 1 (certainty 70%) may be Eastern Wood-Peewee C. virens.
Willow Flycatcher Empidonax traillii. Vocalisation could be of Acadian Flycatcher Empidonax virescens. Any comments are welcome.
Black-eared Hemispingus Hemispingus melanotis. Song (certainty 90%). Probably not this species.
Merida Flowerpiercer Diglossa gloriosa. When checking the original tape, the recording was actually identified as Glossy Flowerpiercer D. lafresnayii. There seems to have been a transcription error (I was able to track it down to a wrong cross-reference I made, when updating the database for the taxonomic changes in this genus). Sorry for that.
We are grateful to Paul Coopmans and Niels Krabbe for pointing out most of the above errors. If you think you found an error on the Cd-Rom, not listed above, send e-mail to Peter Boesman
