“…The set of abiotic variables and vegetation allowed a good prediction of potential habitat, based on the selection/ use of the same habitat by studied birds, confirming the utility of the logit model recommended for studies with small size samples as those associated with predictions of habitat (Martin et al, 2014;Jalkanen and Mattila, 2000). The greatest biodiversity arose in sun exposure and partial-shade areas, mostly the latter, like other studies (Avendaño et al, 2015). Above 1,175 m altitude, the presence of the species studied considerably decreased, in direct relation with the presence of pure forests of A. araucana.…”

Fragmentation and degradation of forest habitats affects (the susceptibility of several species is high) highly sensitive species, provoking a serious decrease in biodiversity. To deal with this problem it is necessary to consider the conservation level of bioindicator species and the development of a sustainable forest management of the natural resources. Within this framework, the current study poses the statistical binomial logit modeling to identify the potential habitat of endemic birds (Rhinocryptids) in rain forests in the south of Chile, biodiversity “hostpot” worldwide. The research allowed to identify a potential area of habitat of 14619 hectares with high probability presence of the studied birds. This area presented certain habitat constraints both topographic and vegetation factors. The studied birds showed a high selection of habitats associated to mixed forests of Nothofagus species, sites with high stratification and understory presence. The low quantity of Rhinocryptidae family species was associated to exclusive forests of Araucaria araucana, which exist at higher altitudes. The model of potential habitat of bioindicator birdlife (avifauna) within a system of geographic information it is presented as an efficient tool of information among the degree of alteration of ecosystems and for decision-makings in native forest management.

“…Differentiating species is particularly challenging for taxa of birds in families that exhibit similar plumages and vocalizations, such is the case of the wrens (Troglodytidae) [1,2], tapaculos (Rhinocryptidae) [3][4][5], antbirds (Thamnophilidae) [6] and New World flycatchers (Tyrannidae) [7]. An interesting case is the Rough-legged Tyrannulet (Phyllomyias burmeisteri).…”

Vocalizations from birds are a fruitful source of information for the classification of species. However, currently used analyses are ineffective to determine the taxonomic status of some groups. To provide a clearer grouping of taxa for such bird species from the analysis of vocalizations, more sensitive techniques are required. In this study, we have evaluated the sensitivity of the Uniform Manifold Approximation and Projection (UMAP) technique for grouping the vocalizations of individuals of the Rough-legged Tyrannulet Phyllomyias burmeisteri complex. Although the existence of two taxonomic groups has been suggested by some studies, the species has presented taxonomic difficulties in classification in previous studies. UMAP exhibited a clearer separation of groups than previously used dimensionality-reduction techniques (i.e., principal component analysis), as it was able to effectively identify the two taxa groups. The results achieved with UMAP in this study suggest that the technique can be useful in the analysis of species with complex in taxonomy through vocalizations data as a complementary tool including behavioral traits such as acoustic communication.

“… Scytalopus griseicollis morenoi is distinguishable from Scytalopus perijanus from the Serranía de Perijá by its entirely brown nape and back (Fig. 1 ) and distinct vocalisations ( Avendaño et al 2015 ). It is diagnosable from Scytalopus griseicollis griseicollis of the Altiplano Cundiboyacense and Scytalopus griseicollis gilesi of the Serranía de los Yariguíes by its brown (not grey) mantle, tail, wing coverts and nape (Fig.…”

“…Recent studies have resulted in new taxon descriptions and reclassifications for at least 30 species (principally in Fjeldså and Krabbe 1990 , Krabbe and Schulenberg 2003 and in many other publications, see Remsen et al 2015 ). Six of these new Scytalopus taxa have been described with a distribution partially or exclusively in Colombia since the late 1990s ( Krabbe and Schulenberg 1997 , Cuervo et al 2005 , Krabbe et al 2005 , Donegan and Avendaño 2008 , Donegan et al 2013 , Avendaño et al 2015 ) and some diagnosable populations in the Colombian Andes remain undescribed (e.g. Donegan and Avendaño 2008 , López-O et al 2013 , McMullan and Donegan 2014 ).…”

A distinctive new subspecies of Scytalopus griseicollis (Aves, Passeriformes, Rhinocryptidae) from the northern Eastern Cordillera of Colombia and Venezuela

We describe a new subspecies of Pale-bellied Tapaculo Scytalopus griseicollis from the northern Eastern Cordillera of Colombia and Venezuela. This form differs diagnosably in plumage from described subspecies Scytalopus griseicollis griseicollis and Scytalopus griseicollis gilesi and from the latter in tail length. It is also differentiated non-diagnosably in voice from both these populations. Ecological niche modelling analysis suggests that the new subspecies is restricted to the Andean montane forest and páramo north of both the arid Chicamocha valley and the Sierra Nevada del Cocuy.
