Colombian birds (1 Viewer)

Rejecting the name 'Tetrasyllabic' on the grounds that it "would not help in the museum" seems mildly hilarious, and perhaps opens the door to the corollary that any common names that don't help in the field should be expunged.
 
This map shows a continuous distribution of S. verapacis from Central America to Ecuador, including most of Panama (only excluding the Tacarcuna range in extreme eastern Panama); however, it is acropholites (and not panamensis) the form found in the Tacarcuna region (specimens collected at Cerro Mali and Cerro Tacarcuna). Panamensis is found in the lowlands of central Panama (around the canal, and where it is partially sympatric with dumicola-like birds living in the adjacent foothills -Cerro Azul/Jefe-) and both lowlands and foothills in eastern Panama, including the Alturas de Nique range (where Cana and "Cerro Pirre" are); thus, bisecting the known range of what we are now calling S. verapacis.
 
Jan, I am curious about one location in Panama, a site called San Francisco that was a couple of hours east of the airport along the main highway, and not far from the highway. I have assumed it is panamensis that would be found in that location, does that fit with your impression?

thanks
Niels

Completely! I still need to watch (or hear) this bird there, but it is panamensis the expected one.

This is a summary of known records of this species in Panama. However, if you look at the comments which accompany the map, criticisms are a bit overstated. Both of these occur in eastern Panama - a major omission in Nyari (2007) despite Ridgely & Gwynne noting this as long ago as 1989 in their field guide. Studies in better known regions (canal zone of Panama) show these two taxa to be sympatric, with unpublished field data from present researchers suggesting that they may be elevational replacements. The Darien region has only stenorhyncha group (inc. panamensis) records and recordings to date, but is relatively poorly sampled compared to the canal zone. Maybe the mountainous region there acts as a complete barrier between separated veraepacis group [includes dumicola] populations with only stenorhyncha there; or maybe further work will show both to occur, as would be consistent with what happens in ecologically similar habitats further west.

Donegan, Quevedo, Verhelst, Cortés, Pacheco & Salaman 2014. Revision of the status of bird species occurring or reported in Colombia 2014. Conservación Colombiana 21: 3–11. [pdf]
Abstract
The following species are added to Colombia's bird checklist: Pacific Parrotlet Forpus coelestis (sight record, Nariño), Couch's Kingbird (Tyrannus couchii) (lost specimen, Providencia), Foothill Elaenia (Myiopagis olallai) (recently described subspecies, Antioquia) and Painted Bunting (Passerina ciris) (photograph, San Andrés). Proposed splits are accepted of Sclerurus Leaftossers (with three species in Colombia: andina, obscurior and peruviana), Bicolored Antbirds Gymnopithys leucaspis / bicolor and Three-striped Warblers Basileuterus tristriatus / tacarcunae. Photographs and sonograms are presented of some of these split taxa. Colombian subspecies occidentalis of Great-billed Seed-Finch Oryzoborus maximiliani is lumped into Large-billed Seed-Finch O. crassirostris. Several amendments to genus and species names, English names and linear order are made, following recent publications. As a result of these changes, the Colombian checklist again increases again, to 1,911 species (excluding escapes), of which 1,835 are documented by 'confirmed' records on the mainland.

From Guy Kirwan:

"Remarks from the Recordist
Have included this population within meridanus, for now, given postulated relationship in Hilty (2003) and Salaman et al. (2007), and bearing in mind the discussion in Donegan & Avendaño-C. (2008), but it is to be described as a new taxon, presumably at species level, shortly."

Birds of Colombia 2015

Lynx-BirdLife Taxonomic Checklist
Maybe with criticisms on both the splitters' and lumpers' sides of different committees, this means a semblance of balance has been achieved? We are going through all the splits relevant to Colombia right now and noted a number of good novel insights. Also some stuff (e.g. in toucans especially) that makes little sense. But overall a lot of useful proposals that helps takes things forwards. Watch this space for a discussion based on analysis of actual taxonomic proposals rather than all this rhetoric...

Abstract
Subtropical Pygmy-Owl Glaucidium parkeri, Fiery-tailed Awlbill Avocettula recurvirostris and Pale-rumped Swift Chaetura egregia are added to Colombia's bird checklist based on photographic records. Band-rumped Storm-Petrel Oceanodroma castro, Golden-spangled Piculet Picumnus exilis, Yellow-bellied Flycatcher Empidonax flaviventris and Yellow-throated Tanager Iridisornis analis are all elevated to the status of confirmed species occurring on the mainland, also following photographic records. We considered taxonomic proposals by del Hoyo & Collar (2014) using Tobias et al. (2010)'s "species scoring system". We studied possible changes relevant to Colombia in detail, based on new studies of vocalisations, our own fieldwork data and published molecular studies. We conclude that the following proposed Trochilidae (hummingbird) splits are supported by differentiation in voice: White-throated Wedgebill Schistes albogularis from Geoffroy's Wedgebill S. geoffroyi (Wedge-billed Hummingbird); Longuemare's Sunangel Heliangelus clarisse and Merida Sunangel H. spencei from Amethystine Sunangel Heliangelus amethysticollis; White-tailed Hillstar Urochroa leucura from Rufous-gaped Hillstar U. bougeri; and Humboldt's Sapphire Amazilia humboldtii from Gray's Sapphire A. grayi. In light of these positive assessments, we accepted proposed splits of morphologically distinctive hummingbirds in a little-vocalising genus: Perija Starfrontlet Coeligena consita and Golden Starfrontlet C. eos from Golden-bellied Starfrontlet C. bonapartei and Green Inca C. conradii from Collared Inca C. torquata. We adopt the proposed split of Double-banded Puffbird Hypnelus bicinctus from Rufous-throated Puffbird H. ruficollis, highlighting vocal differences. We suggest transfer of subspecies striaticollis to the bicinctus group. We split Splendid Woodpecker Campephilus splendens from C. haematogaster based on differences in voice, plumage, distribution and drumming behaviour. Carribean Coot Fulica caribaea is lumped with American Coot F. americana on account of widely reported intergradation. After studying vocal differentiation in three genera, we reject 10 proposed splits in Ramphastidae (toucans) of forms which either intergrade with one another or which are not as vocally distinct as sympatric toucans. Our vocal analyses instead suggest that the Groove-billed Toucanet subspecies Aulacorhynchus sulcatus erythrognatus of Venezuela may merit species rank. The widely adopted split of Andean Duck Oxyura ferruginea from Ruddy Duck O. jamaicensis is again rejected, due to well-documented intergradation in Colombia. We conclude that del Hoyo & Collar (2014)'s taxonomy has been useful and worthwhile in drawing attention to novel taxonomic situations, especially in Trochilidae. However, we suggest using the Tobias et al. (2010) system as a point of reference and not a sole criterion to determine taxonomic rank. After analysis of sound recordings of putative related species, we conclude that Providencia Vireo V. approximans merits species rank. We split the Blossomcrowns Anthocephala. Several amendments to genus and species names, English names and linear order are made, following recent publications. The Colombian checklist increases again to 1,922 species (excluding escapes), of which 1,847 are documented by 'confirmed' records on the mainland.
