The Corvid family are known for their smarts and often for a bit of attitude. The Yellow-billed Magpie, Pica nuttalli, certainly have these features. They are one of two species endemic to the State of California, the other being the Island Scrub Jay, Aphelocoma insularis.
I have previously posted on the birds susceptibility to the West Nile virus and, in some areas, populations seem to be down by up to 80%. In others where mosquitoes are better controlled, they seem to be doing well.
