Estudio preliminar de las plantas que usan las aves nectarívoras para su alimentación en tres áreas verdes de Bogotá

Abstract

To figure out the interactions among plants coverings of urban green areas of the city and the fauna that inhabits there, such as nectarivorous birds, is a strategy to improve the learning around plants that create nectar resource for these birds and the functions they fulfill for the conservation of biodiversity and ecological connectivity. This assumption becomes the aim of this work, which took place in three green areas of the Main Ecological Structure (EEP, acronym in Spanish) of Bogotá: El Chicó Sector, Quinta de Bolívar and El Delirio Reserve, which surrounds the Cerros Orientales, or that they are part of they in the case of the Reserve. The interactions established among the nectarivorous birds in each area were determined by counting points between July and October 2017. A total of 15 species of nectarivorous birds were recorded by using the floral resources of 42 plant species, with predominance of the families Onagraceae, Ericaceae, Myrtaceae and Solanaceae. The plants with the highest frequency of visits were those whose flowers had characteristics associated with the syndrome of ornithophilia, such as tubular and flared corollas, red, orange and yellow colors; the visits were mostly legitimate, enhancing the pollination function of birds. In this way, it contributes to a better understanding of the role of urban and periurban plant coverage in the maintenance of ecological interactions, and to the importance of certain plant species that can be taken into account or prioritized in the processes of urban revegetation.
