Abstract The species-group in the genus Percnostola that is sometimes placed in the genus “Schistocichla” is shown to consist of seven, mostly allopatric, species. All seven are distinct morphologically; when their vocalizations were compared, 19 of 21 pairwise comparisons resulted in differences as great as or greater than those of syntopic species-pairs in this family. Differences in the two remaining comparisons were limited to two vocal characters, but one involved a pair whose ranges… 
Species Limits in Antbirds (Thamnophilidae): The Scale-Backed Antbird (Willisornis poecilinotus) Complex
TLDR
Within the widespread Willisornis poecilinotus, Common Scale-backed Antbird, the remaining instances of parapatry without extensive intergradation provide a focus for future fieldwork to define interrelationships in contact zones and mechanisms of species recognition that may be sustaining them on independent evolutionary paths.
Phylogeny and phylogenetic classification of the antbirds, ovenbirds, woodcreepers, and allies (Aves: Passeriformes: infraorder Furnariides)
TLDR
A phylogenetic analysis of the Furnariides sampling 124 genera supports the Melanopareidae and Grallariidae as distinct from the Rhinocryptidae and Formicariidae, respectively and erects new family‐group names for clades having high branch support across methods.
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.
Taxonomic revision of Myrmeciza (Aves: Passeriformes: Thamnophilidae) into 12 genera based on phylogenetic, morphological, behavioral, and ecological data.
A comprehensive molecular phylogeny of the family Thamnophilidae indicated that the genus Myrmeciza (Gray) is not monophyletic. Species currently assigned to the genus are found in three of the five
Species limits in the Rusty-breasted Antpitta (Grallaricula ferrugineipectus) complex
TLDR
Northern and southern groups of Rusty-breasted Antpittas are divergent in genetics, vocalizations, and morphology, demonstrating that these taxa are best classified as 2 monophyletic, biological species with allopatric distributions.
A new subspecies of mountain tanager in the Anisognathus lacrymosus complex from the Yariguíes Mountains of Colombia
TLDR
The darker plumage of the new subspecies of Anisognathus lacrymosus resembles that of A.l. intensus of the West Andes, presenting a ‘leap-frog’ pattern of geographic variation.
Vocal variation and species limits in the genus Sirystes (Tyrannidae) Variación en vocalizaciones y límites de especies en el género Sirystes (Tyrannidae)
TLDR
Considerable variation in the kind of primary and secondary vocalizations are evident between these four proposed species, with primary vocalizations of particular taxa appearing as rare orsecondary vocalizations or not being given at all by others.
Variación del canto de Hylophilus flavipes (Aves: Vireonidae) en tres regiones del valle del río Magdalena, Colombia Variation in Hylophilus flavipes (Aves: Vireonidae) song in three regions of the Magdalena River Valley, Colombia
TLDR
This study compared the vocalizations of H. flavipes from different populations present in in three regions of the Magdalena valley of Co- lombia, using 22 recordings divided into three populations.
Postzygotic isolation drives genomic speciation between highly cryptic Hypocnemis antbirds from Amazonia
TLDR
The results support intrinsic postzygotic isolation as a driver of speciation in a moderately young cryptic species pair from the Amazon and suggest that species richness of the Amazon may be grossly underestimated.
Sexually Selected Traits Predict Patterns of Species Richness in a Diverse Clade of Suboscine Birds
TLDR
This is the first study to reveal correlations between song structure and species diversity, emphasizing the importance of acoustic signals, and within‐family analyses, in comparative studies of sexual selection.

SPECIES LIMITS IN ANTBIRDS (THAMNOPHILIDAE): THE WARBLING ANTBIRD (HYPOCNEMIS CANTATOR) COMPLEX
TLDR
The finding that common calls were as diversified as Songs in this species-group suggests that calls may be as important as songs in reproductive isolation and future field studies should focus on clarifying the function of different types of thamnophilid vocalizations and elucidating their role in speciation.
A NEW SPECIES OF PERCNOSTOLA ANTBIRD (PASSERIFORMES: THAMNOPHILIDAE) FROM AMAZONIAN PERU, AND AN ANALYSIS OF SPECIES LIMITS WITHIN PERCNOSTOLA RUFIFRONS
TLDR
A description of the new species of Percnostola antbird, an analysis of how it differs from the four previously described subspecies, and a reconsideration of species limits within P. rufifrons are presented.
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),
CLINAL VARIATION IN VOCALIZATIONS OF AN ANTBIRD (THAMNOPHILIDAE) AND IMPLICATIONS FOR DEFINING SPECIES LIMITS
TLDR
The first quantitative study of a species in a suboscine family to test for clinal vocal variation, this vocal study found clinal variation in the pace of male loudsongs, and revealed that the geographic pattern of the clines was consistent with genetic variation found in the companion molecular study.
Use of vocalizations to establish species limits in antbirds (Passeriformes: Thamnophilidae)
TLDR
It is recommended that multiple diagnosable vocal characters be present when vocalizations are a major factor in determining species limits in thamnophilid antbirds, and that three vocal characters, the minimum number distinguishing the syntopic pairs, be used as a point of reference.
AVIAN SPECIATION IN THE PANTEPUI: THE CASE OF THE RORAIMAN ANTBIRD (PERCNOSTOLA [SCHISTOCICHLA] “LEUCOSTIGMA” SATURATA)
TLDR
The first records for Guyana of Roraiman Antbird (Percnostola “leucostigma” saturata), an endemic of the tepui highlands of southeastern Venezuela, northern Brazil and western Guyana, are recorded.
On heterogynism in formicarian Birds
TLDR
During the past few years the wonderful Amazonian material accumulated in the collection of the Carnegie Musemn at Pittsburgh, Pa., threw much new light on the subject and served as principal basis for the following notes.
Behavior and vocalizations of the caura and the yapacana antbirds
TLDR
Based on newly described vocal characters, the closest relatives of P. caurensis appear to be P. leucostigma and P. schistacea, whereas M. disjuncta has no apparent close relatives and probably merits placement in a monotypic genus.
Guidelines for assigning species rank
Developments in several fields of study (including bio-acoustics and the analysis of DNA) together with reappraisals of the nature of species have impacted significantly on avian taxonomy. The BOU’
