“…Our results indicate a link between acoustic variation and geographic distance, which is not surprising given that geographic distance is considered a key component of acoustic variation in many animals, especially for animals that exhibit strong philopatry and limited dispersal (Isler et al ., ; Prohle et al ., ; Ortiz‐Ramírez et al ., ). Insectivorous understory birds, like wrens, are generally thought to have limited dispersal (Stouffer & Bierregaard, 1995; Sekercioğlu et al ., ; Moore et al ., ), and genetic patterns as well as banding data indicate that this is the case for Rufous‐and‐white Wrens (Graham et al ., ).…”

Given the important role that animal vocalizations play in mate attraction and resource defence, acoustic signals are expected to play a significant role in speciation. Most studies, however, have focused on the acoustic traits of male animals living in the temperate zone. In contrast to temperate environments, in the tropics, it is commonplace for both sexes to produce complex acoustic signals. Therefore, tropical birds offer the opportunity to compare the sexes and provide a more comprehensive understanding of the evolution of animal signals. In this study, we quantified patterns of acoustic variation in Rufous-and-white Wrens (Thryophilus rufalbus) from five populations in Central America. We quantified similarities and differences between male and female songs by comparing the role that acoustic adaptation, cultural isolation and neutral genetic divergence have played in shaping acoustic divergence. We found that males and females showed considerable acoustic variation across populations, although females exhibited greater population divergence than males. Redundancy analysis and partial-redundancy analysis revealed significant relationships between acoustic variation and ecological variables, genetic distance, and geographic distance. Both ambient background noise and geographic distance explained a high proportion of variance for both males and females, suggesting that both acoustic adaptation and cultural isolation influence song. Overall, our results indicate that parallel evolutionary forces act on male and female acoustic signals and highlight the important role that cultural drift and selection play in the evolution of both male and female songs.

“…Specifically, we found significant acoustic differences among three allopatric populations in the superciliosus group (Pacific, Chiapas, and Central America). Divergence in acoustic traits has been found to occur widely among allopatric populations (e.g., Toews and Irwin , Cadena and Cuervo , Chaves et al , Sosa‐López et al , Sosa‐López and Mennill , Ortiz‐Ramírez et al , Sandoval et al ). For example, geographic isolation of Wedge‐tailed Sabrewings ( Campylopterus curvipennis ) driven by paleoclimatic historical events might explain the vocal, genetic, and morphological differentiation exhibited by allopatric populations (González et al ).…”

Geographic variation and divergence of songs in the Olive Sparrow species complex

Phenotypic traits such as songs are important in species recognition. Variation in acoustic traits can form barriers to gene flow and promote speciation. Therefore, understanding song divergence is crucial in groups with controversial taxonomy such as Olive Sparrows (Arremonops rufivirgatus), a widespread Neotropical species of songbird with multiple allopatric populations. Taxonomic authorities disagree on the number of Olive Sparrow subspecies, placing them into either two or three main groups. These groups may represent separate species based on morphological traits, but trait divergence within the complex has not been examined. We studied geographic variation in the characteristics of the songs of Olive Sparrows at two geographical levels: among three proposed groups and among five allopatric populations. In a second analysis, we evaluated the strength of acoustic divergence within the complex by comparing acoustic distances among groups and allopatric populations of Olive Sparrows with the acoustic distance among three recognized species in the genus Arremonops. We analyzed 802 songs from 174 individuals across 81 locations and measured 12 variables to describe the fine structural characteristics of the songs of Olive Sparrows, Green‐backed Sparrows (A. chloronotus), Black‐striped Sparrows (A. conirostris), and Tocuyo Sparrows (A. tocuyensis). We found significant acoustic variation in the Olive Sparrow complex at both geographical levels. Our divergence analysis also revealed that vocal divergence within the complex is similar to or greater than that found between recognized species in the genus. Together, these results suggest that acoustic diversity within the Olive Sparrow complex probably originated by isolation in tandem with selective and/or non‐selective factors.

“…Like the songs of C. fuscescens, the sonograms of C. d. dryas resemble a caret grapheme (^), whereas songs from South America were structurally similar to the central phrases in songs of the Wood Thrush (see Stein 1956), consisting of 2-5 'whistled' notes in an ascending, descending or alternating frequency pattern. Ortiz-Ramírez et al (2015) recently showed a considerable degree of geographic variation in song structure among C. frantzii subspecies, coincident but not necessarily correlated with deep genetic divergences. That finding may, like our own, reflect the existence of cryptic species in the C. frantzii complex, a matter that deserves further study.…”

In the 1850s, two species of "Spotted" Nightingale-Thrush (Aves: Catharus) were independently described from montane rainforests of Guatemala, C. dryas (Gould, 1855) and Ecuador, C. maculatus (Sclater, 1858). However, due to similarities in plumage color, C. maculatus was reclassified as a subspecies of C. dryas in 1878, a decision that has been upheld for 137 years. We collected multiple lines of evidence including phylogenetic analysis of mitochondrial DNA sequences (ND2), discriminant and principal components analysis of morphometric and vocal data, and statistical modeling of ecological niches, that collectively indicate that C. d. dryas and C. d. maculatus are independent species. We recommend restoring species status to C. maculatus of South America and applying the common name Sclater's Nightingale-Thrush to this species.En los años 1850s, dos especies de "zorzalito" (Aves: Catharus) fueron descritas en las selvas montañosas de Guatemala, (C. dryas Gould, 1855) y Ecuador, C. maculatus (Sclater, 1858). Sin embargo, debido a la similitud en el color del plumaje, en 1878 se reclasificó a C. maculatus como una subespecie de C. dryas, una decisión que se ha mantenido por 137 años. A través de múltiples líneas de evidencia, incluyendo un análisis filogenético con secuencias de ADN mitocondrial (ND2), análisis discriminantes y componentes principales de los datos morfométricos y vocales, y modelos estadísticos de nichos ecológicos, encontramos que colectivamente estos resultados sugieren que C. d. dryas y C. d. maculatus son especies independientes. Recomendamos regresarle el nombre taxonómico de C. maculatus a la especie de América del Sur.
