EnglishThe biodiversity of Chilean avifauna has been shaped by geological events, geographical factors and extreme climatic regimens. Molecular genetic studies developed to date have begun to provide valuable information to elucidate the effect of these factors on the evolutionary history of Chilean birds. We conducted a search in two bibliographic databases (PubMed and Scopus) over the period between 1998 and 2018 to identify the number and class of articles published in this research field. The quantification of specific research categories was also performed to assess progress in different molecular genetic issues of Chilean birds. Representative studies of the more active research areas: population structure, phylogeography, systematics and taxonomy and genetic diversity, were briefly commented on. Studies on genetic divergence analysis of cryptic species and the underlying genetics at molecular level of adaptive phenotypes in populations, were very scarce. Several types of mitochondrial and nuclear markers have been used, with COI plus D-loop and microsatellite loci, respectively, being the most widely-used markers. However, high-throughput analyses based on complete mitochondrial genomes have also been published. More than one hundred species have been analyzed; the most studied groups being penguins, followed by New World swallows. Although, to date, molecular genetic studies of Chilean birds still require further analysis, the studies available on some species or groups have provided important data to improve our understanding of the origin and evolution of this avifauna. portuguesA biodiversidade da avifauna Chilena foi moldada por eventos geologicos, fatores geograficos e regimes climaticos extremos. Estudos geneticos moleculares desenvolvidos ate o momento comecaram a fornecer informacoes valiosas para elucidar o efeito desses fatores sobre a historia evolutiva das aves chilenas. Foi realizada uma busca em duas bases de dados bibliograficas (PubMed e Scopus) ao longo do periodo entre 1998 e 2018 para identificar o numero e a classe de artigos publicados neste campo de pesquisa. A quantificacao de categorias especificas de pesquisa tambem foi realizada para avaliar o progresso em diferentes problemas geneticos moleculares. Estudos representativos das areas de pesquisa mais ativas: estrutura populacional, filogeografia, sistematica e taxonomia e diversidade genetica, foram brevemente comentados. Estudos sobre divergencia genetica de especies cripticas e genetica de populacoes em nivel molecular de fenotipos adaptativos, foram muito escassos. Diversos tipos de marcadores mitocondriais e nucleares tem sido utilizados, sendo a COI mais D-loop e microssatelites, respectivamente, os mais utilizados. Nao obstante, analises de alto rendimento baseadas em genomas mitocondriais completos tambem foram publicadas. Mais de cem especies foram analisadas; os grupos mais estudados sao os pinguins, seguidos pelas andorinhas do Novo Mundo. Embora, ate o momento, estudos geneticos moleculares de aves chilenas ainda exijam mais analises, os trabalhos disponiveis sobre algumas especies ou grupos forneceram dados importantes para melhorar nossa compreensao da origem e evolucao desta avifauna.
