This is in the 'Desert' greenhouse. There is a big flock of Cutthroat Finches, probably 40/50- they make a nice display when seen in a single species flock like that. I've always liked this building- or the display that's in there at any rate.
Couldn't agree more, Pertinax; it's one of the best displays in any UK zoo. Probably the only potential breeding flock of Queleas [once a common import and still regarded as an agricultural pest] in the UK. Agreed the Cutthroats are great, but they are fairly well established in private aviculture.
