Abstract
Statement of the Problem: The Pantanal biome one of the most diverse for avifauna when compared to wetlands such as the Everglades (Florida), Okavango Delta (Africa), Llanos (Venezuela) and Esteros de Ibera (Argentina), where 650, 365, 450, 258 and 343 species are found, respectively. The aim was to survey the avifauna of two routes in the Pantanal wetland (BR419 and MS170), Aquidauna (MS), to determine the avifauna of the region and their distribution throughout the Americas.
Methodology & Theoretical Orientation: BR419 (Taboco road) between the coordinates 20°26'49''S 55°47'01''W and 19°52'50''S 55°29'41''W. The other transect was on MS170, Retirinho road, between 20°26'23''S 55°48'10''W and 19°53'13''S 56°01'29''W. The observation times alternated between both routes avoid biasing sampling by time of day, i.e. when MS170 was sampled in the morning, the same or next afternoon the BR419 transect was sampled, the next time the transects were reversed by time of day. Both transects were sampled for a total of 14 sampling events, obtaining a total of 103 hours and 06 minutes of observations.
Findings: Were observant 125 species, thus, 58 live just in South America (SA); 17 live in SA and Central America; 19 live the SA at México; 27 live at Mexico plus USA; two arrive Canadian [Falco sparverius and Tyrannus tyrannus]; and two cosmopolites [Pandionhaliaetus and Passer domesticus]. Using the classification of the IUCN (2017) one endangered species were observed [Buteogallus coronatus]; two near threatened [Pyrrhura devillei; Rhea Americana], and a two vulnerable [Sporophila maximiliani; Anodorhynchus hyacinthinus].
Conclusion & Significance: Many species in the Aquidauana region live only in SA, but others inhabit the of the Americas. It is important to have a comprehensive understanding of migration of these birds that have large ranges. This information is of paramount importance considering the possibility of dispersal of seeds, eggs, and even diseases. The study area should variety of species classified as endangered, vulnerable and near threatened.
