You cant go from FC to PC with some Elephants because it's not fair on them they get a lot from keeper contact you get things like this happening all the time anyway you just don't hear about it. I have worked with Elephants FC and sometimes when there wasnt enough keepers in that day you would have to work PC which just comfused them. Having worked with Elephants for a number of years FC I think that it should be up to the Elephant Keepers themselves if they want to work FC or PC not someone sitting in a office having never worked with Elepants FC before. It's mainly bunny huggers that like PC!
Having worked in zoos and aquariums for some years and also had some hands on experience during this time covering elephant sections I have to disagree.
Indeed, just moving from one style of handling to another is exactly what you do not want to be doing and if you move from Free Contact (FC) to Protected Contact (PC) it has to be undertaken slowly and in stages as you would in training any behaviours and there has to be planned consent from the keepers taking part. It also requires prober staffing levels. If, as you say, management where not supplying suitable staffing levels for PC to operate effectively which meant staff had to resort to FC that is basically down to bad management and clearly animals would become confused.
One thing, of course, you have overlooked is that many collection may well have to move from FC as insurance companies may soon not cover zoo staff handling animals in what is considered a risky manner when safer methods i.e. PC are considered available.
I have to say in all honestly that I have never been impressed with the treatment I have seen by *some* elephant handlers where corporal punishment seems to be normal in getting animals under control. It doesn't surprise me in the least that when you establish such dangerous dominant hierarchies that keepers are attacked and/or killed at some point
BTW: Protected Contact is not being used just for elephants and been successfully used on primates and big cats and also Stella sea lions which can be too dangerous to train in a Free Contact environment.
