Visitors:
The last Friday of the official count season for HBMO has been
completed. As the primary coordinator/counter for Friday’s this year, I
would like to thank all those who have visited the Tower on Friday’s this
season to view hawks or assist in the daily count of raptors.

 How does this season’s 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 hawkwatcher’s version of Ockham's Razor*; “If the
wind had been from another direction the numbers would have been
different.”

 Well I haven’t yet calculated the season’s 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!

  • Ockham's Razor is the principle proposed by William of Ockham in the
    fourteenth century: Pluralitas non est ponenda sine neccesitate'', which translates as entities should not be multiplied unnecessarily''.

Weather:
100% clouds mostly altocumulus, wind South 4-8 mph, temp. 3.4C, 29.99 in
Hg,, 70 % Rel Hum., visibility 17 Km.

Observations:
3 Adult Bald Eagles and 1 or 2 juv BE - All resident individuals or
non-migrants.

Migrants: one each harrier and red-tailed.

One each of Kingfisher, Chickadee, Downey woodpecker, Carolina Wren,
Flicker, Cardinal.

Many approx. 94 Goldfinch, 5 Bluebird, 4 Swamp Sparrow, 2 Song Sparrow, 10
Tree Sparrow.

Predictions:
Overcast.  High:  42° F  /  6° C  Wind  WSW  22 mph  /  36 km/h
