Re: "Look Up!"
Just a point here, Grinnell was a genius but in this case his speculation
is a little shaky. Snowy Owls and Northern Goshawks do not share the same
home, at all. The owl breeds on tundra, the hawk in various forested
habitats. If there was a situation where the two erupted together, it was
likely a coincidence, or a massive rodent population crash over wide areas
and different habitats. If the latter was the case, all sorts of other
raptors should have moved south. The hawk that would likely move in tandem
with Snowy Owl would be Rough-leg.
