Are birds the only species that is susceptible to West Nile Virus infection?
West Nile Virus (WNV) has been detected in at least 48 species of mosquitoes, over 320 species of birds, at least 2 species of reptiles, and more than 25 mammalian species, including horses and humans.
Birds are the natural host and reservoir of WNV. Although other animals are susceptible to WNV infection, only birds develop a high enough virus load to transmit the infection to an uninfected mosquito.

Curlews are very attentive parents and fly close to intruders and alarm call to distract them from their young broods. USGS scientists take advantage of this behavior by using a mist net to sweep birds out of the air when they approach. In June 2007, USGS scientists used this approach to tag 13 curlews with satellite transmitters at their southern breeding area in Alaska....
