Rediscovery of the Dusky Starfrontlet Coeligena orina, with a description of the adult plumages and a resassessment of its taxonomic status( )

in English and held by 1 WorldCat member library worldwide

After being known only from the type specimen, an immature male, for over 50 years, the Dusky Starfrontlet Coeligena orina was rediscovered en 2004 at the type locality and another site 70 km to the south in the Western Andes of Colombia. Four specimens were collected, permitting the first descriptions of the adult male and female plumages. From these specimens we conclude that C. orina is a distinct species, probably most closely related to C. bonapartei and C. lutetiae, rather than a subspecies of the former (as it has been considered in much recent literature). It differs more in plumage colors and measurements from C. bonapartei, than do the races of the latter among themselves; the differences are comparable in magnitude to those between bonapartei and the sympatric C. helianthea. C. orina appears to be restricted to elfin forest and the páramo-forest ecotone between ca. 3100 and 3500 m in the northern part of the Western Andes. The type locality of Páramo Frontino is currently threatened, and effective protection measures are urgently needed. We recommend that based upon estimates of its current population size and limited available habitat, C. orina be classified as Critically Endangered

Ending fifty years of confusion : the anomalous record of the Pale-legged Warbler (Basileuterus signatus) in Colombia by F. Gary Stiles( )

in English and held by 1 WorldCat member library worldwide

I present evidence that the supposed Colombian record of the Pale-legged Warbler (Basileuterus signatus) is based upon a specimen of the Citrine Warbler (B. l. luteoviridis) that was incorrectly sexed and aged by the collector or preparator and identified in the absence of adequate comparative material. Examination and measurements of museum specimens of both species permitted definitive identification of the problematical specimen. I conclude that B. signatus should be removed from the list of the Colombian avifauna
Notas taxonómicas sobre aves colombianas I : el rango taxonómico de Hylocharis hunboldtii (Trochilidae) by F. Gary Stiles( )

in Spanish and held by 1 WorldCat member library worldwide

En la vertiente del Pacífico de Colombia, existen dos colibríes 'zafiros' del género Hylocharis: grayi, descrito por Delattre y Bourcier en 1846 y humboldtii, descrito por Bourcier y Mulsant en 1852. El primero habita los valles y laderas secos de la cordillera desde Valle del Cauca, Colombia hasta Pichincha, Ecuador. En cambio, humboldtii ocurre solamente en manglares y zonas adyacentes a lo largo de la costa pacífica desde el este de Darién, Panamá hasta el norte de Esmeraldas, Ecuador. Ambas formas son casi endémicas (en el sentido de Stiles 1998) a Colombia

A review of the genus Momotus (Coraciformes: Momotidae) in Northern South America and adjacent areas by F. Gary Stiles( )

in English and held by 1 WorldCat member library worldwide

Over the last sixty years, most of the more than 20 named taxa of the genus Momotus have been included in a single widespread, variable species, Momotus momota. In recent decades, several authors have questioned this broad species concept and suggested splitting this " Momotus momota complex" into two or more species. However, for want of a detailed analysis no consensus has been reached regarding which and how many species should be recognized. The present study therefore seeks to provide criteria for redefining species limits in this complex through analyses of external measurements, plumage patterns and the 'hooting' primary songs among ten focal taxa occurring in the area between Nicaragua, northern Peru, Trinidad-Tobago and Guyana. Five external measurements of bills, wings and tails were made on 512 specimens of the focal taxa and an additional 30 specimens of taxa occurring in adjacent regions; data on body masses permitted use of relative mean measurements of external dimensions to examine differences in form as well as in absolute size. A subsample of 183 specimens was scored for 14 characters of plumage pattern of the underparts, crown, pectoral "stickpin", borders of the mask and tail racquets. The focal taxa break into two groups with respect to the primary song: those in which the song consists of a single long note vs. two shorter notes. Five parameters of duration and frequency were measured on sonograms of taxa in the one-note group; these and an additional six parameters were measured on sonagrams of those of the two-note group, and two-note "duet" songs of one taxon of the one-note group. Data were analyzed with t-tests, ANOVA, discriminant analysis and principal components analysis. I defined species limits in this complex on the basis of two general criteria: diagnosability and the probability that the differences observed would assure maintenance of reproductive isolation should currently allopatric groups enter into contact. My results support recognition of five species-level taxa in this complex: lessonii Lesson 1842 (including 2-3 additional subspecies in Mexico beyond the scope of this study), momota Linnaeus 1766 (including the nominate, microstephanus Sclater 1855 and several other subspecies of eastern and southern South America beyond the scope of this study); M. aequatorialis Gould 1857 (including the subspecies chlorolaemus Berlepsch and Stolzmann 1902); bahamensis Swainson 1837 and subrufescens Sclater 1853. In the latter species I recognize as subspecies osgoodi Cory 1913, argenticinctus Sharpe 1892 and spatha Wetmore 1946, but find the following taxa not adequately diagnosable and recommend lumping them into nominate subrufescens : conexus Thayer & Bangs 1906, reconditus Nelson 1912 and olivaresi Hernandez & Romero 1978
