Lansing's Potter Park Zoo is taking extra precautions with its animals after two snowy owls recently died, possibly as a result of the West Nile virus.
Zoo officials say they've sprayed the duck pond and other stagnant pools of water to prevent mosquitoes from breeding.
They've also inoculated several equine animals including horses, donkeys and the rhinoceros. Experts say the equine family is especially susceptible to the West Nile virus.
Although research is not complete, experts say a West Nile virus horse vaccine - developed about one year ago - appears to be helping in the prevention of the West Nile disease in horses.
Zoo officials say they're testing the horse vaccine on its exotic birds - including the black vulture and the bald eagle. Veterinary experts say the vaccine should not have any adverse effects on the birds.
The zoo is still waiting for test results to confirm whether or not the West Nile virus killed its two snowy owls.

- 1 in 100-150 who get sick become seriously ill.
- 3 to 15 percent of those seriously ill die.
