Visitors seldom see tigers due to the dense, tall grass. The rhinoceros is the real star of the park. Kaziranga also has one of the very last populations of truly wild Asian water buffalo, but even here there are many feral descendants of domesticated water buffalo, and hybridization occurs. The park is also the last haven for greater adjutant storks, with fewer than one hundred nesting pairs.
