 By adding all 6 GIS data layers (e.g., vectors, birds, water, vegetation) to the previous human population GIS layer, we derive a model that predicts potential WNV infections to people.  High risk areas are identified as SE and SW Pheonix, the Yuma,  N Tucson and Verde Valley regions. 
We next examine if any specific groups of birds are more likely to be infected with WNV.  To accomplish this, we recorded 'vertical' foraging height of birds along the Lower Colorado River, in S Arizona.  Each bird species is identified by their 4-letter AOU code. 
 We next looked at the vertical height distribution of Culex in the vegetation.  This mosquito will probably be the major vector of WNV in Arizona.
By combining bird foraging height with the vector distribution pattern, we predict that species such as the Warbling Veiro (WAVI)  would have higher prevalences, while birds like the White-crowned Sparrow (WCSP) would have lower infection rates.
