[MARMAM] Raptors and dolphins

Dears, I have made multiple observations of Brahminy Kites fishing with Irrawaddy dolphins. I can find however, no evidence of other Acciptirids/raptors engaging in any such behaviour in the literature. If ladies or gents have ever made similar observations, I'd be interested to hear about it (gryan@wwf.panda.org). Best, gerry ryan
