Habitat fragmentation is considered one of the major threats to biodiversity today. Cities have contributed to fragmentation through forest suppression and conversion of green areas in urban environment. Sometimes, small green areas are kept in the cities and serve as refuge and shelter for several bird species. In the city of Mauá-SP, the Parque Ecológico do Guapituba, with 536,760m², will be studied to evaluate the ecological resilience of bird communities and identify which species are more resilient. It will be used two forest patches in the park, with different size and shape. Several point counts will be established in the patches for bird survey. Bird species will be classified in feeding guilds in order to assess ecological resilience. Species composition and abundance in each guild will be compared between the two areas to determine the variation in species resilience according to the difference in size and shape of the areas, as well as the distancing in relation to the bigger patch of better conditions. It is expected that species that remain present and do not suffer abundance reduction between the two habitat conditions can be considered as resilient, contributing to the conservation planning of urban forest fragments.
