Parrots, I'm a bird man too although not particularly a parrot person. I like to see all animals (although if I never see another meerkat I won't shed a tear) but my preference is birds. I'm therefore inclined to spend more time at Wingz. I also tend to linger at exhibits longer than most people, a bit like yourself I expect, so even small collections can take me longer than most.
PS Have you been to Birdworld as it "sounds" perfect for me.
I agree with you on Meerkats so maybe I should warn you that Wingz has them and you can buy (I presume you still can) Mealworms to feed them. Unfortunately I have managed only one visit to Birdworld and that was back in 1999 - I enjoyed it very much though. I had hoped to combine a trip to "Think Parrots" with another visit there in June but because I took on an abandoned Yellow-bellied Terrapin (via ZooChatter madgeandshane who initially took it after it had been left in a flat following a moonlight flit) in January I have decided not to take any holidays as, unlike my parrots, it is not practical to take it to a friend's house for the duration.
