Oct 23 2010, Kiev/Ukraine -- About 1,500 birds have been found dead on an Ukraine island, authorities said Saturday.

Most of the birds were cormorants, but a large number of herring gulls were also found on Ukraine's Bolshoi Dzendzik Island, the emergencies ministry said.

Specialists from the local veterinary office have taken samples for laboratory testing to establish the cause of the birds' death.
