Differences in temporal and territorial feeding patterns of various tropical Trochilidae species as observed at two different ecosystems in Soberanía National Park

This study aims to illustrate differences in feeding patterns and displays of territorialism at two artificial feeding sites, located in two ecosystems; one site in a secondary forest of Soberanía National Park, the other in a residential area in the nearby town of Gamboa. Four 1-hour observation periods were recorded each day for four days at both sites. During each period of observation, the allocation of time to the three activities of perching, flying, and feeding was recorded, along with the number of visits the feeders. Notes were taken on patterns of territoriality as connected to species and sex. Significance was found in the different allocations of time at both locations. Significantly more time was spent perching at the Park Feeders, and significantly more time was spent flying at the Lodge Feeders. Additionally, while there was no correlation found between the period of observation and the number of visits to the feeders and the Lodge, there was correlation found at the Park feeders, as the earlier the observation period, the more visits were recorded to the feeders. Overall, F. mellivora was the clear dominant species and males exhibited the majority of territorial displays at both sites, however observationally, individuals were more aggressive for longer periods of time at the Lodge Feeders.
