Birds of the Parque Ecológico Lagoa da Fazenda, Sobral, Ceará state, northeastern Brazil

Natural areas within cities are important as they contribute to maintain biodiversity and the functioning of ecosystems. In Ceara state, inventories of birds in human-impacted areas are still scarce. Here, we inventory bird species and estimate the species richness at Parque Ecologico Lagoa da Fazenda, an urban park in the municipality of Sobral, in northeastern Brazil. We found 82 bird species, of which 16 breed in the area, three are endemics, and three others are introduced. Despite the moderate species richness detected, richness estimators revealed that sampling was sufficient to detect most species. To maintain or even increase local species richness, we suggest the cessation of urban expansion within the park, sewage dumping, and filling of the wetland, as well as further planting of native vegetation.
