So I assume your following comments regarding frequency were for
broad-wings, and not red-shoulders. It got me interested enough to dig up
my records from the GGRO (San Francisco hawk watch); I only have 84-90 data
on hand, but it shows RSHA as regular there, as one would expect. Low count
of 104 in '85, high of 194 in '87. BWHA has a low count of 9, in '84, but a
high in '90 of 153, a year in which the RSHA count was 155.

Some of the difference would be attributable, I think, to better i.d.
skills of the watchers, and to better coverage (more watchers); '84 was the
first year of the official GGRO count, I believe. But that wouldn't explain
all of the difference. Interesting as it is, but it will be even more
interesting to follow these numbers for another twenty or thirty years, to
see where they go.
