What I think I have learned this year counting at Ashton Ridge about Broad Winged
Hawks as it pertains to this area:
Overall they are influenced with the need to go southwest. The winds influence their direction
southwest from day to day. The thermals influence their route and elevation hour-by-hour and minute-by-minute.
I believe Lynchburg or all large cities generate hefty thermals and that is a magnate to Broad Wings.
Ashton Ridge is located about 12 miles southwest from the center of Lynchburg and about 5 miles southwest from the edge of
Lynchburg. If the thermals are not as strong between Lynchburg and Ashton Ridge, the opportunity exists to see
large numbers as in 2008. The winds were also favorable in 2008, not so much in 2009 as they had been from the east
all month and that influenced larger numbers against the ridges. The elevation is 900 feet at AR and it is easy for
the large numbers to be high out of sight. This was observed this year many times, BWs disappearing into higher elevations
working thermals.
Close coordination was carried out between Ashton Ridge and Candler's Mountain. Interesting data was
collected. Perhaps Gene Satler will make some observations of that data in the future.
It was interesting to see the number of Eagles and Ospreys; that was not expected.
