Gidday all,
Thanks for info on viewfinder refresh strobing.
On Black Falcons.
1: In August 2003, blue-sky day at Lake Belmore, Croydon's sparkling new water
supply lake, a stiff nor'easter sweeping many insects across the surface and
hitting a small bluff created a vertical 'restaurant' for raptors. First level
fed a pair of Nankeen Kestrels and a pair of Australian Hobby. Above and
dipping down into the tier were many Whistling Kites and Black Kites. Higher in
the column were Brown Falcons being jostled and outmuscled by Grey Falcons
(yes, two, also seen day previous). Above them, riding the column, almost
effortlessly stationary and occasionally taking short stoops straight down, was
a 'hovering' Black Falcon. Bigger, much darker, 'stoopier'. A dark morph Brown
might look a bit like a Black, no Black I've seen looked like a Brown. (Also in
the sky that morning, a distant Peregrine and a towering-height Wedgetail. Nine
raptors aloft, and a pair of resident White-bellied Sea-eagles turned up later!)
2: July 2003, later afternoon camped below Cumberland Dam spillway, 20km west
of Georgetown, Black Falcon skimmed overhead (loud whooshing of wings), circled
back low across water into Chinee apples on dam's earth walls and flashed out
again straight over the top of me (faster, but less whoosh). Also had sightings
of distant bird(s) stooping above low ridges in the area over 6-7 days. Sure,
the eye sees black and dark grey under colours, but the mind remembers a big
black speeding killer unlike any Brown Falcon.
Is that too subjective?
Cheers, Tony Ashton
