Species: Peregrine Falcon vs Juvenile White-bellied Sea-Eagle
Location: Limestone hills, Tambun Interior, Perak, Malaysia
Date: 14th August 2010
Equipment: Nikon D90 SLR with Tamron AF Zoom 200-500mm, handheld
A few White-bellied Sea-Eagles (Haliaeetus leucogaster) are present
around the fringe of the city, nesting around large ex-mining lakes near limestone hills. I have previously posted an aerial battle between a Juvenile White-bellied Sea-Eagle and a crow in the city.
We also have a few resident Peregrine Falcons (Falco peregrinus ernesti), as opposed to the migratory one. I know of a pair that uses the limestone hills to breed. I have previously posted an aerial battle between 2 different pairs of Peregrine Falcons at the Tambun location.
I had arrived early (7.50 am) on the 14th August at the Tambun interior limestone site of the nesting Peregrine Falcons and saw another aerial battle between one of them and a Juvenile White-bellied Sea-Eagle. They were some distance away but managed to document the activity. I witnessed 3 rounds of conflict before the Juvenile White-bellied Sea-Eagle was chased away. The White-bellied Sea-Eagle has this habit of aerial summersaults, seen it occasionally.
This is unlikely to be a territorial dispute as much as possible “kleptoparasitic attacks on other raptors” (see Wells 1999) as no large bodies of water nearby.
