They can found in swamps and estuaries at sea level up to an elevation of around 1,700 m (5,600 ft).[1] Their favorite habitat is riverine forests with large trees, although large numbers are also found on islands with large, old trees within larger rivers, swamps or lakes, so long as the islands are not too far from the bank. The species is largely residential and has no seasonal movement, although young, non-breeding birds may wander somewhat before claiming their own territories. Pel's fishing owl may move outside of their own range in pursuit of prey.
