Rhinoceros Hornbill, Jurong BirdPark

Taken with a mobile phone cam, hence the small size and poor quality.

It's Beautiful. It's a female, but what subspecies?

I'm not sure Jon, Jurong keeps breeding pairs for 3 subspecies (B.r.borneoensis, silvestris, rhinoceros).

It's bornean subspecie (Buceros rhinoceros borneoensis)
