“…We sampled 107 individuals of A. taciturnus from 67 localities (GenBank accession numbers –; Fig. and Table S1) comprising both subspecies, and excluded A. t. axillaris , which we consider a separate species following Buainain et al (). We were not able to sample A. franciscanus , the closest extant relative of the A. taciturnus complex (Klicka et al ).…”

“…A. taciturnus was considered to be polytypic, with three currently recognized subspecies: A. t. axillaris , occurring along the base of the Andes in Colombia and Venezuela; A. t. nigrirostris , recorded in Peru and Bolivia along the eastern slope of the Andes; and A. t. taciturnus , extending from southeastern Colombia, east to southern Venezuela and the Guianas, south through Amazonia to central Brazil and northeastern Bolivia, and along the Atlantic coast of Brazil south to Espírito Santo (Jaramillo & de Juana ). However, Buainain et al () have shown that A. t. axillaris can be phenotypically diagnosed from the remaining subspecies and argued that it should be recognized as a distinct species. In contrast, A. t. taciturnus and A. t. nigrirostris are polymorphic, with both taxa sharing character states varying from having a complete pectoral band to its absence.…”

We focus on reconstructing a spatiotemporal scenario of diversification of a widespread South American species, the Pectoral Sparrow Arremon taciturnus (Aves: Passerellidae). This species is widely distributed in both the humid and the dry forests of South America and therefore provides an interesting model for understanding the connection between different biomes of South America. We examined nucleotide sequences of the mitochondrial genes Cytochrome b (cyt‐b) and NADH subunit 2 (ND2) from 107 specimens, and one nuclear marker (intron 7 of the β‐fibrinogen gene) from a subset of samples collected across the distribution ranges of A. t. taciturnus and A. t. nigrirostris. Six major lineages were recovered in the phylogenies that displayed high levels of variance of allele frequencies and corresponded to distinct geographical locations. The estimation of divergence times provided evidence that diversification of the six lineages of the Pectoral Sparrow occurred throughout the Late Pleistocene across major cis‐Andean biomes and Amazonian interfluves. Our dataset for A. taciturnus provides further evidence that rivers in Amazonia constitute barriers promoting allopatric speciation, with occasional sharing of alleles among lineages, particularly those with adjacent distributions.

“…A presença e ausência de notas curtas introdutórias e variações no número de notas em populações de A. taciturnus também foram observadas em outro estudo (Buainain, 2017). No entanto, o mesmo autor não considerou como uma variação geográfica consistente.…”

“…O tico-tico-de-bico-preto, A. taciturnus (Hermann, 1783), possui três subespécies atualmente reconhecidas: A. taciturnus taciturnus, A. taciturnus nigrirostris e A. taciturnus axillaris (Buainain, 2017). A subespécie A. taciturnus taciturnus é uma ave que vive nas porções mais próximas ao solo de florestas húmidas e bosques, ocorrendo do leste da Colômbia até o sul da Venezuela, nas Guianas e no Brasil, podendo ser encontrado na região central da Amazônia brasileira, nos estados de Tocantins, Goiás e no nordeste, atingindo até os estados de Minas Gerais e Espírito Santo.…”

ResumoEstudos recentes apontam que as florestas estacionais do nordeste brasileiro são formadas por duas unidades biogeográficas distintas, uma relacionada a Floresta Atlântica costeira e outra com os domínios da caatinga. Esta pesquisa pretendeu verificar se existe algum grau de diferenciação morfométrica e acústica entre as populações de Arremon taciturnus (Tico-tico-de-bicopreto) em florestas de altitude no Nordeste do Brasil, localizadas a leste e a oeste do planalto da Borborema. Com esta finalidade foram realizados testes paramétrico (teste t) e não paramétrico (teste U), de acordo com a normalidade dos dados acústicos, analisando se existe diferença significativa entre os parâmetros vocais das populações. Para verificar se existem diferenças biométricas entre as áreas estudadas foi realizada uma análise discriminante e de correspondência. Estas, por sua vez, não apresentaram diferença. Entretanto, as análises bioacústicas apontaram diferenças em parâmetros do canto como número de notas e em parâmetros como duração da 1ª, 2ª, e 3ª nota da segunda parte do canto. A. taciturnus é uma espécie que possui capacidade para aprendizado do canto. Desta forma, as diferenças encontradas em alguns parâmetros vocais pode ser indício de uma variação interespecífica nas populações, chamadas de dialetos vocais.

Song and morphometric comparison among Arremon taciturnus populations in Northeastern BrazilAbstract Recent studies indicate that the seasonal forests of the Brazilian Northeast are formed by two distinct biogeographic units, one related to the Atlantic Coastal Forest and another to the caatinga domains. This aim intended to verify if there is any degree of morphometric and acoustic differentiation between the populations of Arremon taciturnus (Tico-tico-de-bico-preto) in high altitude forests in the Northeast of Brazil, located to the east and west of the Borborema plateau. For this purpose, parametric (t-test) and non-parametric (U-test) tests were performed according to the normality of the acoustic data, analyzing whether there is a significant difference between the vocal parameters of the populations. To verify if there are biometric differences between the studied areas a discriminant and correspondence analysis was performed. These, in turn, showed no difference. However, bioacoustic analysis pointed to differences in singing parameters such as number of notes and parameters such as duration of 1ª 2ª and 3ª notes of the second part of the song. A. taciturnus is a species that has the ability to learn the song. In this way, the differences found in some vocal parameters may be indicative of an interspecific variation in the populations, called vocal dialects.
