The maintenance of a costly flowering strategy is probably necessary to guarantee the presence of hummingbirds in the area, the main pollinators. It has apical inflorescences, exposed in natural forest corridors, thereby facilitating discovery by the territorial and non-territorial hummingbirds that use the corridors as foraging paths. Each month, we estimated the species richness of the hummingbird community based on the censuses, observations at flowering bromeliads, and opportunistic records. Coadapted competitors: the flowering seasons of hummingbird-pollinated plants in a tropical forest. Around 10-12 foraging bouts h-1 were performed, lasting approximately 90-120 s, during which hummingbirds visited 14.6 + 8.3 flowers from 4.67 + 1.95 plants. Lower fruit production by flowers that were experimentally rendered rigid may be due to fewer and shorter visits by short-billed hummingbirds. Both sing (the hummingbird adds a courtship dance), defend territories and mates, raise young, and migrate seasonally for long distances. We performed two censuses per monthly field trip to estimate hummingbird abundance. There is a morphological correspondence between the length of hummingbird bills and the length of the corollas in ornithophilous flowers. However, we observed that hummingbirds with much shorter bills were also able to extract nectar and pollinate the flowers. The same procedure was used to calculate the similarity of the hummingbird species according to the bromeliads used by each species. However, the most common motif by far on the picks-and the only motif to appear on provenienced picks-is avian, and most frequently a hummingbird. In addition, hummingbirds were associated with love and lovemaking. Around this time of the year, hummingbirds were rarely seen, while flowers continued to be visited by insects.
