BUFFALO, N.Y. — Three polar bears have died at the Buffalo Zoo since August 2006, leading authorities to question the care given to the animals and the condition of their enclosures.
One bear died after apparently falling into an empty pool; the others swallowed pieces of stone and plastic.
A recent U.S. Department of Agriculture inspection report raises concerns about the deaths and other incidents, including the death of a hyena found pinned under a boulder.
The USDA is working with the zoo on the issues raised in the August report, officials said.
