O presente trabalho foi realizado na ESEC- Serid?, localizado no sert?o do Rio Grande do Norte. As coletas foram realizadas em duas esta??es clim?ticas, seca e chuvosa durante os anos de 2013 e 2014. Foram utilizadas redes de neblina para captura das aves e coleta de sangue e posteriormente t?cnicas de laborat?rio para extra??o e amplifica??o de DNA e diagn?stico de presen?a de hemospor?deos. Foram amostradas 779 aves, compreendendo 9 fam?lias e 20 esp?cies. A preval?ncia total obtida nos dois anos de amostragem foi de 54%, n?o apresentando diferen?a entre as esta??es seca e chuvosa. As condi??es ambientais da ESEC-Serid? nos anos da coleta estiveram favor?veis para o desenvolvimento de alguns dos vetores de hemosporidioses. O habitat das aves influencia muito em sua hist?ria de vida. Por isso tanto a guilda tr?fica quando o ambiente que as aves frequentam apresentaram rela??o com a infec??o por hemospor?deos. Desta forma, o presente trabalho tem por objetivo principal avaliar a preval?ncia de hemospor?deos em aves da Caatinga presente na Esta??o Ecol?gica do Serid?. / Infection with hemosporids has been studied in several parts of the world, as this is considered an important factor in the decline of populations of several species of birds. The present work was carried out at ESEC-Serid?, located in the hinterland of Rio Grande do Norte. Fieldwork was carried out in two seasons, dry and rainy during the years of 2013 and 2014. Mist nets were used to capture birds and blood collection and later laboratory techniques for extraction and amplification of DNA and diagnosis of presence of hemosporids. A total of 779 birds were sampled, comprising nine families and 20 species. A total prevalence of 54% was obtained for the two sampled, with no difference between dry and rainy seasons. Environmental conditions of ESEC-Serid? in the sampled years were favorable for the development of some of the vectors of hemosporidioses. Therefore, both the trophic guild and the environment that the birds frequented had a relation with the infection by hemosporids. In this way, the main objective of this study was to evaluate the prevalence of hemosporids in Caatinga birds present in the Esta??o Ecol?gica do Serid?.
