Differences In Temporal And Territorial Feeding Patterns Of Various Tropical Trochilidae Species As Observed At Two Different Ecosystems In Soberanía National Park, Delaney Vorwick
Independent Study Project (ISP) Collection
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 …
Andean Condor Nesting And Behavior: A Study Of A Free-Living Pair And Chick As Well As Population Behavior Near Antisana Ecological Reserve, Ecuador, Ian Handler
Independent Study Project (ISP) Collection
The behavior of the Andean condor (Vultur gryphus), especially nest behavior, is little known outside of captivity. More information on chick-parent interactions and parenting dynamics of successful condor pairs is needed in order to help create an effective conservation plan for a species in peril of extinction. Study of nest home used by a free-living pair of condors and home to a five-month old juvenile began on November 11, 2018 and continued through November 29, 2018. The nest is located in Antisanilla Biological Reserve and nearby Antisana Ecological Reserve. The chick was also tagged with numbers and a tracking device …
Harpy Eagle (Harpia Harpyja) Conservation: Juvenile Behavior And Diet At A Nest Near Pijibasal, Darien, Hannah Rodgers
Harpy Eagle (Harpia Harpyja) Conservation: Juvenile Behavior And Diet At A Nest Near Pijibasal, Darien, Hannah Rodgers
Independent Study Project (ISP) Collection
The Harpy Eagle (Harpia harpyja), the largest and most powerful bird of prey in the Americas, is declining throughout its range in Neotropical forests. Hunting and deforestation threaten populations in the most important remaining eagle habitat in Central America, the Darien province of Panama. These eagles may have the longest postfledging juvenile dependency of any raptor, though juvenile behavior during this period is poorly studied. This study monitored an 11-month-old juvenile for 7 days at a nest near the indigenous community of Pijibasal in order to study behavior and diet. Researchers recorded the juvenile’s location and behavior, studied prey remains …
