Didn't they stop keeping hornbills briefly this year? I thought one had left to be paired with a lone bird at Dublin zoo and new, younger hornbills of the same species were arriving from another zoo. I had assumed this meant one of the old breeding pair had died and that there must have been a recommendation for Cotswold to take on a new young pair as they are one of the few collections with experience of successfully breeding this species, as well as having a new flight aviary built recently for them.
Correct on all counts. Last summer their Aviary contained Blue Touracos, with a notice explaining Giant Hornbills would be returning- they may have done so by now but it has broken their continuum with this species.
They also claim to be the first in the UK( & elsewhere?) to have bred them.
