It's one of the most stressful things zoo administrators across the country deal with - the quadrennial inspection by the Association of Zoos and Aquariums, or AZA.

Jay Pratte is the first-year Executive Director of the Miller Park Zoo in Bloomington and indicates today and tomorrow, inspectors from the AZA will be at his zoo to give a fine-toothed comb examination.

Pratte indicates these representatives from the AZA will leave no stone unturned - both literally and figuratively.

Pratte calls the process very intimidating because it is an evaluation of your practices and policies. He says they want to make sure the missions of zoos are being carried out in their facility.

Upon the departure of the AZA inspectors, the Miller Park Zoo then makes changes to its plans and begins to modify facility improvements marked out. Later this summer in Columbus, Ohio.
