Tweeters/Inlanders: the following is a copy of my response on the
subject.
I hope it is relevant and makes sense.
November 25, 1999
Chief, Office of Migratory Bird Management,
U.S. Fish and Wildlife Service,

(fax: 703/358-2272).
I do not think that falconers should be allowed to take Peregrine falcons
for their sport until there is a thorough analysis of the raptor
migration data available from Hawk Watch International and other
organizations. These data show trends in raptor numbers over a long
period of time (17 to 22 years in the case of HWI).
I have the current year to date for the Goshutes site as of October 28,
1999. The count ended in early November. Current and long-term data can
be obtained by contacting HWI director Howard Gross at
hgross at hawkwatch.org for all the observation sites for which they are
responsible.
The current year data that I have shows a total raptor count of 19,833
passing through the Goshutes site. Of this amount 12 were Peregrine
Falcons a fraction of a percent (.0000029%).
Sharp-shinned hawks were 36% (7,074); Cooper's hawks were 19% (3,844);
Red-tailed hawks were 23% of the total (4,498) and American Kestrels were
12% (2,467).
The Veracruz site, largest in the Northern Hemisphere also has long-term
data on raptor populations. The 1999 final corrected total shows
Peregrine falcons (957) to be another miniscule fraction of one percent
(.000235%) of the total raptor migration (4,077,152). Broad-winged hawks
made up 43% of the total; Swainson's 14% (581,419); turkey vultures 36%
(1,474,797).
If TV's are removed from the data the percentage of peregrines becomes
..0003677% still a low percentage.
I do not know that much about the migratory habits of Peregrine Falcons
and whether or not these data are relevant or not. I am only suggesting
that the raptor counts are one way to scientifically determine the
numbers and relative health of a species before making a decision that
will impact on them.
