  Figure 1. Map of Brazil showing the study region (circle; ES = Espírito Santo and RJ = Rio de Janeiro), located in the southeast of the country (A). Maps of the locations where fecal samples were obtained from birds analyzed in this study: (B) map of the state of Rio de Janeiro showing the cities of São José do Vale do Rio Preto in the East Region, and Bom Jardim in Bom Jardim in the Center Region of the state; (C) map of the state of Espírito Santo showing the city of Marechal Floriano in the Southwest Region of the state.

  Figure 2. Dendrograms constructed from complete or partial sequences of the VP1, VP2, VP4, VP6, VP7, NSP1, NSP2, NSP4, and NSP5-encoding genome segments of RVF strains. Distances were corrected using the Kimura 2-parameter model. The dendrogram was constructed using the maximum likelihood method. Statistical support was provided by bootstrapping 1000 pseudoreplicates. Bootstrap values above 70% are given as branch nodes. GenBank reference strain accession numbers are shown next to the strain identification. RVF strains detected in this study are indicated by black triangles.
