I love visiting botanical gardens around the world probably just as much as I like to visit decent zoos. I've often found that many of these institutions house live displays of captive smaller animals such as inverts, reptiles, amphibians, fish and birds (sometimes free-ranging) within their glass houses / conservatories. Personally, I've always felt that seeing animals alongside botanical collections really makes a visit to one of these gardens extra special. Probably because it highlights both animal and plant life and gives a much more holistic view of life on earth. What botanical gardens you have visited keep live displays of animals and what species are kept ?
