FIGURE 6. Geographic distribution of Sporophila maximiliani based on museum specimens, literature, and field records (see appendices), defining locations where the species is probably extirpated and sites with recent records (<10 years). Gray shading indicates the range of the species according to BirdLife International (2017). Colors represent terrestrial ecoregions according to Olson et al. (2001).
FIGURE 8 in Taxonomy, natural history, and conservation of the Great-billed Seed-Finch Sporophila maximiliani (Cabanis, 1851) (Thraupidae, Sporophilinae)
FIGURE 8. The typical habitat of Sporophila maximiliani. Upper left: Formoso river and its seasonally flooded fields (foreground) in ENP. Upper right: gallery forest of Formoso river in ENP. Middle: Flooded area in Itiquira, Mato Grosso, Brazil, where a breeding pair was found. In this area, a vereda with moriche palm forest was surrounded by marshes formed by the overflow of the veredas. Bottom: another flooded area in Itiquira, with concentrations of moriche palm and concentration of Cyperaceae. In all these areas, several species of Cyperaceae are abundant. Photographs taken by FKU.
