SCOTTSBLUFF, Neb. (AP) — A zoo in Scottsbluff is facing staff turnover troubles as two members have resigned and another has been terminated.

The Riverside Discovery Center board recently decided to let go of zoo director Peter Halliday.

Board president Martin Mickey says former executive director Anne James unexpectedly resigned shortly after Halliday was terminated. The board is currently searching for a new executive director.

And Education Curator Amber Schiltz left in July to take a position with the Bird Conservancy of the Rockies. A new curator has been hired to replace her.

After the three departures, the board asked the Association of Zoos and Aquariums for assistance. Association spokesman Rob Vernon says inspectors visited the zoo to confirm there were no deficiencies that would warrant a change in accreditation status.
