| Resumo: |
This study investigated the species of hummingbird occurring in an area of caatinga vegetation, examining their seasonal activities, the assemblages of plants that they used, as well as the floral characteristics and flowering phenology of that vegetation. These surveys were performed in an area of arboreal caatinga in Chapada Diamantina, municipality of Mucugê, state of Bahia, Brazil, during 12 expeditions undertaken on a bi-monthly basis between October, 2005 and August, 2007. Field activities included observations made of the visiting hummingbird species, their behavior, and the frequency of their visits; as well as the plant species visited, their floral attributes, size, and the flowering phenophase evident on the occasion of each expedition. Seven species of hummingbirds were registered, including five residents. Phaethornis pretrei (Lesson & Delattre, 1839) acted as the organizer of this pollination guild. This species and Chlorostilbon lucidus (Shaw, 1812), these two species were considered the principal pollinators within the community. The hummingbirds visited a total of 29 plant species, of which only 12 are considered ornitophilous. The plant community presented a continuous flowering, with 19 species flowering in both the dry and the rainy season, permitting the year-round permanence of resident hummingbird species.
