@Dhole dude
before you pay to get in, there is a series of bird enclosures, I believe these guys were in the enclosure before the Red-Tailed Black Cockatoo
@King of Komodo Dragons I believe the normal rufous has an entirely red bill. @StellarChaser Likely from a private breeder - they’re around in the US, DWA is not the only zoo with them
@jayjds2@King of Komodo Dragons Yep - it's the bill colour - the sharp colour demarcation where the 'white' starts marks out mindanensis, while hydrocorax is all red - Colchester's 'pair' are one of each and this photo has a nice comparison: Rufous hornbill - ZooChat
