Description
However, since dead bird surveillance was initiated in Alberta, a great deal has been learned on WNv activity. We now know that suitable conditions for WNv are limited largely to the Grassland Natural Region of southeastern Alberta where conditions are most favourable for development of Culex tarsalis. In addition, the number of dead corvids each summer has declined significantly since WNv first appeared, although the populations of crows and magpies did not decline. It is likely that crows and magpies, as well as all the other birds species exposed to WNv, adapted to the presence of WNv in the ecosystem and developed protective immunity. The monitoring of dead birds was discontinued in 2007 because it no longer provided new information about WNv; however testing is conducted on suspect cases as a response to public concern.
