Another bit of info about Black Vultures: they are also expanding in
Arizona. When I first started coming here in 1997, you had to go
Lukeville on the Mexican border to see them. I first saw 2 outside of
Phoenix the first year they were reported in the Upper Valley. Now
they occur as far north as Wickenburg, about 200 miles from the border
(and no interstate between here and there).
