Introduction:

The Osprey (Pandion haliaetus) is a migratory bird of prey commonly found along the East Coast of Banda Aceh and Aceh Besar. This study aims to document the behavior and foraging patterns of Ospreys in two specific locations: Alue Naga, Aceh Besar, and Kampung Pande, Banda Aceh. Despite being solitary birds, Ospreys exhibit unique foraging behaviors, particularly in response to tidal changes and the presence of fish. This study provides insights into the ecological dynamics of Ospreys and their interactions with other avian predators such as the Brahmini Kite and White-bellied Sea Eagle in the region.

Behavioral Observations:

Ospreys in the study area demonstrate distinct foraging behaviors, primarily observed during tidal changes. When the tide is high or low, Ospreys are frequently observed perching in trees or soaring overhead, scanning the water surface for potential prey. Once a suitable fish is spotted, the Osprey executes a graceful glide towards its target, using its sharp talons to catch the prey. Interestingly, Ospreys often carry their catch to a nearby branch to consume, showcasing a unique feeding behavior not commonly observed in other raptors.

Foraging Habitat:

The study sites of Alue Naga and Kampung Pande offer ideal foraging habitats for Ospreys due to their open spaces in mangrove areas, which were previously used as shrimp ponds. These areas boast a rich biodiversity of fish, providing ample prey for the Ospreys. The proximity of these sites, merely 10 kilometers apart, suggests a significant overlap in foraging ranges for Ospreys in the region.

Interactions with Competitors:

Despite potential competition from other avian predators such as the Brahmini Kite and White-bellied Sea Eagle, Ospreys in the study area seem to coexist peacefully. Occasionally, Ospreys can be observed soaring alongside White-bellied Sea Eagles, particularly when both species are hunting for fish in the sea. This suggests a level of ecological niche differentiation among these predators, allowing them to exploit different prey resources without significant conflict.

Conclusion:

The observations presented in this study shed light on the behavior and foraging patterns of Ospreys in the East Coast of Banda Aceh and Aceh Besar. The unique feeding behaviors and habitat preferences of Ospreys highlight the importance of preserving mangrove ecosystems and maintaining healthy fish populations in the region. Further research is warranted to explore the long-term implications of anthropogenic activities on Osprey populations and their ecological interactions with other avian predators.
