 For example, incidences of pairs preying on species such as the mongoose ("Galarella sanguinea"), monitor lizard ("Varanus" spp), tree squirrel ("Paraxerus cepapi") and scrub hare ("Lepus saxatilis") have been recorded.In three of these four events, cooperative behaviour between the birds was apparent, thereby suggesting that this behaviour is not uncommon.There was also no observable agonistic behaviour between birds while feeding, and the birds appeared practiced and unaffected by the presence of an observer.
