The footage revealed by wildlife rangers shows the juvenile eagle scooping up the video recorder, and taking to the sky.
Wildlife rangers had set up the motion-sensor camera at a gorge on Margaret River in Western Australia's remote Kimberley in May, to capture images of fresh-water crocodiles.
A few weeks ago, they got a phone call to inform that a team of rangers had found the camera at the Mary River, about 110 kilometres away, 'ABC News' reported.
They have been able to extract three 30-second clips that reveal the culprit to be a thieving sea eagle.
Later, the eagle dropped the camera on ground and pecked at the device, the report said.
