Zoo officials examine what's in a name for their animals http://www.pittsburghlive.com/x/tribune-review/pmupdate/s_180539.html
I think it is a good idea to name the animals that have at least some intelligence , or at least name recognition . If there is a large number of primates ( as there is at Wellington zoo ) it makes sense to give them names . It will be easier to say " Bobby doesnt appear well today " to the vet , rather than" Male chimpanzee M4041 doesnt appear well " The elephants at Auckland zoo respond to keepers calling them by name . I am sure that most animals have some sort of bonding with their keepers and knowing individual animals by name will help that bonding . ( I know it wont work for fish , tarantulas etc ) Sim , you discovered first hand that calling that psychotic camel at Wellington zoo by his name ( Cairo ) managed to noticably calm him down . He does recognise " Cairo " as being himself that you are referring to . I doubt if he will recognise " Male Dromedery camel M0023 "
Last night I went to the Pittsburgh zoo website and read it more thoroughly than what appears on the newsclipping . It appears that the animals have names , but these are known by zoo staff so that members of the public cannot give directions/orders to the animals .
