Behavioral ecology of the lacemaker (Manacus manacus): a small dancing bird from the restinga forests of the Juréia-Itatins Ecological Station Cesar Cestari

Abstract

Detailed information about the natural history and ecological functions of species helps decisions to protect them. In this sense, the biodiversity of species and the intense tourist activity present in the region of the Juréia-Itatins Ecological Station (EEJI) provide the appropriate tools for the dissemination of ecological knowledge and conservation. In this manuscript, I describe the behavioral curiosities and ecological interactions of the lacemaker (Manacus manacus), a dancing and frugivorous bird very common in the restingas of the EEJI region, and which can be easily visualized in its “display arenas” on the forest floor. or looking for fruits of different plant species. The information provided on (1) area and display maneuvers, (2) hierarchy and aggressiveness and (3) frugivory and seed dispersal by the lacemaker was collected in six years of studies (2009-2015) in the region and was discussed based on historical studies on the biology of the genus Manacus. Despite being common, the lacemaker is little known to most people who attend EEJI. The fascinating reproductive display behavior associated with the interactions and ecological functions of this species (e.g. fruit consumption and seed dispersal) is highly important for the maintenance of the restinga ecosystem and can be used to awaken and intensify the environmental education of visitors .
