Mexican agricultural officials say they have euthanized 114 peacocks, ostriches and other birds at a zoo due to an avian virus.
The Agriculture Department's chief of animal health in Guerrero state says zoo officials reported the sudden, unexplained death of more than a dozen peacocks.
Wilfrido Najera Lomeli said Thursday that department officials detected the presence of Newcastle Disease and destroyed the birds.
They also included ducks, guinea fowl, pheasants, piegons, parrots and parakeets. Some were threatened species.
The zoo in the Guerrero state capital of Chilpancingo was temporarily closed while officials continue their investigation.
The virus can infect people, but it is not lethal to humans.
