I am currently working on a very interesting map that uses a "drought index", which is calculated using recent historic precipitation data. This index takes into account the frequency of the rain, and the quantity, which in turn relates to vegetation growth. This index has been shown to explain 90% of the variation in the quail populations for certain regions of Texas. Stay tuned :-)

Now I do agree that quail populations are heavily effected by precip, however I'm a little skeptical that you think this one variable can predict population density correctly 90% of the time. Can you post your data?
Thanks.
