Resumo: | Over 70% of threatened birds in the state of Rio Grande do Sul, south Brazil, inhabit forest environments. The creation and maintenance of protected areas is one of the most important measures aiming to mitigate these problems. However, the knowledge of the local biodiversity is essential so that these areas can effectively preserve the natural resources. Between 2004 and 2009 we sampled the avifauna in two conservation units in Rio Grande do Sul: Floresta Nacional de Canela (FNC) and Parque Natural Municipal da Ronda (PMR), both representative of the Mixed Humid Forest (Araucaria Forest). A total of 224 species was recorded, 116 at FNC and 201 at PMR, ten of which threatened regionally: Pseudastur polionotus, Odontophorus capueira, Patagioenas cayennensis, Amazona pretrei, A. vinacea, Triclaria malachitacea, Campephilus robustus, Grallaria varia, Procnias nudicollis and Sporophila melanogaster. Richness and species composition seem to be related to different stages of forest conservation, to size and connectivity, as well as to the diversity of environments. The better conservation of PMR compared to FNC, allied to its geographic position, results in a richer avifauna, with a larger amount of rare and endangered species, as well as species sensitive to disturbance and endemic to the Atlantic Rainforest. We suggest management actions aiming the conservation and the long-term recovery of natural environments at these sites.
