Abstract
The urban environment has become an object of study by ornithologists, who seek to understand the relationships between this new habitat and the birds that survive within it. Aiming to investigate the composition and richness of the avifauna present at the State University of Maringá and identify temporal changes in species composition, the obtained results were compared to the study accomplished by Krügel (1998) in this same location. Thus, we performed field samplings from August 2007 to July 2008, using transects, with visual and auditive identification. We recorded 74 species belonging to 27 families from 12 orders, during 72 hours of observation. Most species were constant in the study area. The predominant trophic categories were insectivores (46%) and omnivores (20%). Comparing the analyzed periods, we verified a reduction in the number of species, besides the record of new species for the studied location.
Highlights
The colonization process in Paraná State led to strong environmental degradation and a loss of extensive forest areas
The city of Maringá is located in this region, and currently, its forest coverage is better represented in the urban area, with small forest reserves and many trees in the streets, avenues and public squares (GARCIA, 2006)
The urban environment offers opportunities to investigate the interactions between the bird community and the changes in the original environment
Summary
The colonization process in Paraná State led to strong environmental degradation and a loss of extensive forest areas. The urban environment offers opportunities to investigate the interactions between the bird community and the changes in the original environment. In Maringá, studies on the ornithofauna of green areas (woods and parks) were accomplished by Krügel and Anjos (2000) and by Galina and Gimenes (2006) and at the campus of State University of Maringá (UEM) by Krügel (1998). In this context, this study investigated species composition and richness, seasonal and temporal changes of avifauna in the campus of the State University of Maringá (UEM), through comparisons with the results obtained by Krügel (1998)
