Abstract

Hummingbirds (Aves, Trochilidae) and their flowers in an urban area of southern Brazil.

Abstract

The main purpose of this study was to identify the assemblage of flowers used by hummingbirds in an urban area of southern Brazil, as well as to describe the patterns of resource partitioning among the hummingbird species. Twenty two plant species were recorded (10 trees, 9 shrubs, 1 herbaceous and 2 lianas), which flowers are visited by ten hummingbird species. Most of these plants are exotics and regarded as non-ornithophilous. The hummingbirds displayed different combinations of morphological features (mass, bill length, wing length and relation bill/wing), which were reflected in the sets of flowers visited and the community role played by each species. In general, hummingbirds with largest niche breadths were also the most frequent ones, indicating that urban areas could be more suitable for generalist species.
