The last Friday of the official count season for HBMO has been
completed. As the primary coordinator/counter for Fridays this year, I
would like to thank all those who have visited the Tower on Fridays this
season to view hawks or assist in the daily count of raptors.
How does this seasons numbers compared to other seasons? As is usual
we all view the past season differently. Some raptor aficionados feel that
a particular species was not represented by the typical numbers they
recall from previous times. They voice the opinion that species A must
be declining in numbers or that species B is too high and someone must
be double counting them. These individual viewing scenarios play out
year after year with many variations and by a different cast of
characters. But when the curtain comes down on the entire season and the
local site numbers are tallied and averages are compared, the ups and
downs of species numbers is usually modest to slightly significant. The
explanation for the cause for any difference noted in species data is
usually expressed in the hawkwatchers version of Ockham's Razor*; If the
wind had been from another direction the numbers would have been
different.
Well I havent yet calculated the seasons numbers and compared them
with the seasonal averages. I will let the raptor aficionados have a
little more time on their bar stools formulating their hypothesis for
migration numbers. As usual I have had fun meeting old raptors and raptor
friends and making new friendships. The raptor counting/observing world is
get nearer to the six degrees for freedom. Support your local hawkwatch
site and support HMANA. Keep looking up!
