Ask the Conservation Officer (CO)

by Gary Hompland, Regional Conservation Officer Question: "I'm hearing about lots of birds dying from West Nile Virus. How is this going to impact the bird hunting?" Answer: The West Nile Virus is definitely beginning to affect some wildlife populations. To date, the Department's surveillance program has detected West Nile Virus in mosquitoes (the carriers) and many non-game bird species in most of the counties across southern Idaho. We are aware of one sage grouse that succumbed to West Nile Virus in Nevada. It is reasonable to expect more upland birds will be affected. Due to the secretive nature of upland birds, few sportsmen in the field during the summer and brushy habitats, the full effect of the West Nile Virus on upland birds will be difficult to accurately assess. Biologists and wildlife veterinarians are also testing for West Nile Virus in fox squirrels, the ones commonly seen in city parks. Across southern Idaho, many fox squirrels are showing weakness, lethargy, and paralysis and the West Nile Virus is suspected. The Department would like the public's help in monitoring any aberrant behavior or disease in upland game birds as well as birds of prey. Suspected victims should be quickly collected and transported to Department regional offices as soon as possible for testing. Although it has not been shown that humans can contract West Nile Virus by handling infected birds or animals, biologists want to remind the public to treat anything they suspect is infected cautiously and wear gloves when handling. Department biologists also want the public to be aware they have been monitoring wildlife management areas for West Nile Virus for the last three years. Stagnant water areas have been treated with biological insecticides or have been drained. The natural wetlands and marshes contain natural predators for mosquitoes. Dailey searches are also conducted to identify infected birds. The Department wants to remind the public to avoid areas heavily populated by mosquitoes if possible or conduct activities at times to minimize contact. Mosquitoes tend to be most active in the evenings. Wear protective clothing and use insect repellant containing DEET. Around your home, be aware of mosquito breeding areas and reduce stagnant, standing water as much as possible. The impact of West Nile Virus on game populations may never be fully understood. Populations of game birds observed by sportsmen in the field this fall may shed some light on its impact.
