“…Habitat-related dialects extend at least into northern Patagonia, with distinctive songs in the Patagonian shrub-steppe and Andean woodlands, but we must acknowledge that vocal behaviour is poorly understood south of ≈40°S in the range occupied by highly migratory populations. Similarly, though we know that there is geographical variation in song in Brazil [81], it is too poorly known for generalizations to be made.…”

BackgroundThe Neotropics are exceptionally diverse, containing roughly one third of all extant bird species on Earth. This remarkable species richness is thought to be a consequence of processes associated with both Andean orogenesis throughout the Tertiary, and climatic fluctuations during the Quaternary. Phylogeographic studies allow insights into how such events might have influenced evolutionary trajectories of species and ultimately contribute to a better understanding of speciation. Studies on continentally distributed species are of particular interest because different populations of such taxa may show genetic signatures of events that impacted the continent-wide biota. Here we evaluate the genealogical history of one of the world’s most broadly-distributed and polytypic passerines, the rufous-collared sparrow (Zonotrichia capensis).ResultsWe obtained control region DNA sequences from 92 Zonotrichia capensis individuals sampled across the species’ range (Central and South America). Six additional molecular markers, both nuclear and mitochondrial, were sequenced for a subset of individuals with divergent control region haplotypes. Median-joining network analysis, and Bayesian and maximum parsimony phylogenetic analyses all recovered three lineages: one spanning Middle America, the Dominican Republic, and north-western South America; one encompassing the Dominican Republic, Roraima (Venezuela) and La Paz (Bolivia) south to Tierra del Fuego, Argentina; and a third, including eastern Argentina and Brazil. Phylogenetic analyses suggest that the Middle American/north-western South American clade is sister to the remaining two. Bayesian and maximum likelihood coalescent simulations used to study lineage demographic history, diversification times, migration rates and population expansion together suggested that diversification of the three lineages occurred rapidly during the Pleistocene, with negligible gene flow, leaving genetic signatures of population expansions.ConclusionsThe Pleistocene history of the rufous-collared sparrow involved extensive range expansion from a probable Central American origin. Its remarkable morphological and behavioral diversity probably represents recent responses to local conditions overlying deeper patterns of lineage diversity, which are themselves produced by isolation and the history of colonization of South America.

“…Originalmente estudado por Marler & Tamura (1964), nessa espécie os cantos são os mesmos em uma determinada região e permanecem iguais até o limite do território, quando mudam abruptamente para outra variação (Catchpole & Slater, 1995). Uma espécie brasileira do mesmo gênero, o tico--tico (Z. capensis), também apresenta dialetos regionais (Avelino & Vielliard, 2004). Nessas espécies os jovens parecem aprender com os vizinhos da área para onde migram após atingirem a maturidade sexual e não tanto com os pais, ao menos no que diz respeito a essas variações (Bell, Trail, & Baptista, 1998).…”

E um agradecimento especial à Camila G. Coelho, que me acompanhou na minha jornada de ida ao Piauí, no início da pesquisa, e me ajudou na instalação inicial em São Raimundo Nonato. Aos meus amigos Marisa, Melissa, Ana Maria e José, que apesar da distância sempre estão em contato. Aos companheiros de pousada da FUMDHAM, da UNIVASF e de São Raimundo Nonato, pelo companheirismo e amizade: Rosa, Carol e Marcos. E sem esquecer a Reiza, que sempre cuidou de tudo na pousada. À Flavya Mendes de Almeida e ao Centro de Primatas Brasileiros, pelo apoio e auxílio quando os macacos estiveram doentes. Às agências de fomento -Fapesp (Processos 2006/07187--5 e 2006/07190--6), CNPq e Capes -pelo suporte financeiro.Ao IBAMA/Instituto Chico Mendes, pela autorização para a realização da pesquisa dentro do Parque Nacional Serra da Capivara.Ao Francisco "Chico" Reinaldo, meu assistente de campo (ou como ele prefere, mateiro), pela ajuda e apoio durante quase todo o período da coleta de dados e também antes e depois dela, sempre mandando notícias sobre os macacos e o parque. E também o George Reinaldo, que substituiu o pai como mateiro durante um breve período.Um agradecimento especial ao Mássimo Mannu (in memoriam), que me apresentou o Parque Nacional Serra da Capivara e os macacos--prego da área. Ele abriu caminho aos futuros primatólogos do nosso laboratório, mas infelizmente nos deixou antes de completar o seu trabalho.Por fim, agradeço aos macacos--prego, especialmente aqueles com os quais trabalhei no PET e do PNSC, que me pemitiram observá--los e aprender um pouco mais sobre suas vidas e comportamentos. Não há diferença fundamental entre o Homem e os animais nas suas faculdades mentais(...) Os animais, como o Homem, demonstram sentir prazer, dor, felicidade e sofrimento. ABSTRACT Falótico, T. (2011). Tool use by capuchin monkeys (Sapajus libidinosus) of Serra da Capivara National Park. Doctoral Thesis, Institute of Psychology, University of São Paulo, São Paulo.Tool use by capuchin monkeys (Sapajus sp) is currently known in many wild populations in Caatinga and Cerrado biomes. Previous studies in Serra da Capivara National Park -Piauí State (SCNP), showed that the "tool kit" of S. libidinosus in that area was much more diverse than in other populations. One possible explanation for these differences is the occurrence of traditional variations between these populations. The aim of this study was (1) to describe the tools used by two groups of capuchin monkeys in SCNP, their physical characteristics, frequencies of use and demographics within the groups, and to find correlations with physical factors of the environment, (2) search for evidence of socially mediated learning in these behaviors, and (3) determine the possible behavioral traditions of these groups. The tools used by groups Pedra Furada (PF) and Bocão (BC) were made from two materials, stones and sticks. The stones were used as "hammer" to break encapsulated fruits and seeds, "hammer" to loosen soil and dig, "hoe" to dig, "hammer" to pulverize pebbles and stone throwin...

Studies of macrogeographic variation in birdsong involve populations incapable of interbreeding because of physical barriers or separation by large distances. Different patterns have emerged from these studies such as (i) little or no variation exists among individuals or populations from the breeding range, (ii) individual variation is greater than among population variation resulting in no geographic structure, (iii) clinal variation, and (iv) macrogeographic variation where all individuals from several populations on the breeding range share a common song type forming a regional dialect or regiolect. I studied macrogeographic variation in song of the Mourning Warbler ( Oporornis philadelphia (A. Wilson, 1810)). The observed pattern was similar to the fourth category of geographic variation with regiolects. A Western regiolect extended from northern Alberta to western Ontario. An Eastern regiolect stretched eastward from western Ontario and Wisconsin to the Gaspé Peninsula and New England, then southward through the Appalachians to West Virginia. Nova Scotia and Newfoundland each had unique regiolects. Finally, I compared these results to other species with regiolects and assessed the ability of some deterministic hypotheses to explain song divergence (e.g., role of morphology, physical barriers, island isolation).
