I've just visited Twycross and this is definately White-naped Crane found near the Cassowary and Ground Hornbill. The Sarus Crane is supposedly to be found with the Purple Heron and Black Stork in the Bornean Longhouse, however I searched with no luck!?!
I went Twycross on the 28th April and these were not there, but were the week before. The Welsch mountain zoo crow is in there now. Any ideas where these have gone?
