Abstract We document the first records for Guyana of Roraiman Antbird (Percnostola [Schistocichla] “leucostigma” saturata), an endemic of the tepui highlands of southeastern Venezuela, northern Brazil and western Guyana. This form is well differentiated from nominate leucostigma (Spot-winged Antbird) of the Guianan lowlands in morphology, vocalizations, and genetics, and replaces it both altitudinally and ecologically. The two taxa are distributed parapatrically on the continuously forested… 
Phylogeny and biogeography of a subclade of mangoes (Aves, Trochilidae)
TLDR
It is found that several phenomena such as the uplift of the Andes, the marine transgressions of the Plio–Pleistocene, the final closure of the Isthmus of Panama and the climatic oscillations of the Pleistocene might be at least, in part, responsible for the diversification of this group in both the lowlands and the highlands of this region of South America.
Systematic Revision of the Spotted Antpitta (Grallariidae: Hylopezus macularius), with Description of a Cryptic New Species from Brazilian Amazonia
TLDR
A systematic revision of the polytypic Spotted Antpitta based on morphometric, plumage, vocal, and molecular characters revealed the existence of an undescribed taxon endemic to the Madeira—Xingu interfluvium, similar in morphology to paraensis, but vocally and genetically readily distinguished from the latter.
Avifauna of the Easternmost Tepui, Tafelberg in Central Suriname
ABSTRACT We conducted ornithological surveys of Tafelberg mountain, Suriname, in November–December 2005 and August–September 2008 and also surveyed the adjacent lowlands in both forest and savanna
SPECIES LIMITS IN THE “SCHISTOCICHLA”COMPLEX OF PERCNOSTOLA ANTBIRDS (PASSERIFORMES: THAMNOPHILIDAE)
TLDR
Insights into speciation in the complex are relevant to conservation efforts and ultimately will be related to an ongoing genetic study to suggest a phylogeny and contribute to an understanding of avian evolution in Amazonia.
Revising Species Limits in a Group of Myrmeciza Antbirds Reveals a Cryptic Species Within M. Laemosticta (Thamnophilidae)
TLDR
Evidence is presented that only two diagnosable vocal characters may be sufficient for two populations to be considered distinct species in this group of trans-Andean Myrmeciza antbirds, and proposed elevating the Magdalena Antbird to species rank and thus that four species be recognized in the M. laemosticta complex.
Avian Diversification in the Andes: Understanding Endemism Patterns and Historical Biogeography
  • M. Rivero
  • Environmental Science, Geography
  • 2011
TLDR
A significant part of the temporal patterns of origins and diversification of the three groups of birds included in this study can be linked to Earth history, both in terms of the tectonic history of the Andes and of the climatic events of the Pleistocene.
Phylogeny of Thripophagini ovenbirds (Aves: Synallaxinae: Furnariidae)
TLDR
The phylogeny and estimate the time of divergence of this group, the Thripophagini, is reconstructed, using sequences from two complete mitochondrial genes from a total of 115 fresh tissue samples to provide a better understanding of the phylogenetic relationships of the taxa within this group.
EVOLUTION INTO AND OUT OF THE ANDES: A BAYESIAN ANALYSIS OF HISTORICAL DIVERSIFICATION IN THAMNOPHILUS ANTSHRIKES
TLDR
A molecular phylogeny of Thamnophlius antshrikes, a clade of 30 species whose collective distribution spans nearly the entirety of lowland habitats in tropical South America, the eastern slope foothills of the Andes, and the tepuis, finds the highest transition rates were between highland-restricted and lowland-to-highland distributions, with extremely low rates into and out of low land-restricted distributions.
Phylogeny, biogeography, and recurrent evolution of divergent bill types in the nectar‐stealing flowerpiercers (Thraupini: Diglossa and Diglossopis)
TLDR
Differences in hook size among sympatric species, together with habitat partitioning and behavioural differences, can explain the coexistence of multiple species of flowerpiercers at the same locality.
A new Andean element in the lepidopterous fauna of the Guiana Shield: the day-flying genus Erateina DoubleDay, with the description of two new species from Roraima, Tramen and Auyán Tepui (Geometridae: Larentiinae)
Two new species of diurnal moths of the genus Erateina (Geometridae, Larentiinae) are described from the table mountains of the Guiana Shield in the SE Venezuela. The genus is species rich, with 85

CRYPTIC BIODIVERSITY: AN OVERLOOKED SPECIES AND NEW SUBSPECIES OF ANTBIRD (AVES: FORMICARIIDAE) WITH A REVISION OF CERCOMACRA TYRANNINA IN NORTHEASTERN
TLDR
A valid species and subspecies from two areas whose avifaunas are among the best known in tropical South America are recognized, demonstrating that the accurate cataloging of the planet's biodiversity will rely not only on expeditions to remote mountain valleys but also on careful analysis of specimens and information already at the authors' disposal.
New records of birds from the summit of Cerro Guaiquinima, Estado Bolívar, Venezuela
Cerro Guaiquinima, located in the Paragua river basin in the Estado Bolivar, is one of the largest isolated sandstone mesas of the Pantepui region, with an estimated summit area of 1,096 km (Mayr &
Species limits in antbirds (Passeriformes : Thamnophilidae) : The Myrmotherula surinamensis complex
Current species-level taxonomy of Neotropical birds is in need of reassessment but lacks objective methodology and criteria for the ranking of allopatric populations. Previously (Isler et al. 1998),
Andean tapaculos of the genus Scytalopus (Aves, Rhinocryptidae): a study of speciation using DNA sequence data.
TLDR
DNA sequence data is used to test hypotheses about past speciation events and suggests that the commonly observed biogeographic pattern, where related species have long linear distributions along the Andes in different altitudinal zones, arose by divergence in disjunct isolates rather than by parapatric divergence.
EVOLUTIONARY IMPLICATIONS OF DIVERGENT CLINES IN AN AVIAN (MANACUS: AVES) HYBRID ZONE
TLDR
Sexual selection remains a plausible explanation for the observed introgression of vitellinus color traits in these highly dimorphic, polygynous, lek-mating birds.
A New Species of Pygmy-Owl (Strigidae: Glaucidium) from the Pacific Slope of the Northern Andes
TLDR
Genetic, vocal, ecological, and morphological data indicate that G. costaricanum should be elevated to species level, and it along with the new species are considered allospe- cies within the Northern Pygmy-Owl superspecies complex.
