Besra 松雀鷹 (male)

Shing Mun Reservoir
14 Feb, 2012

Too sad, I could not capture its tail, due to too long of my lens.

Digiscopic shots, 30X eyepiece, Lumix G1+ 45mm lens.
(original uncropped image, 45mm x 2 (crop factor in G1) X 30 (30X eyepiece of the scope)=2700mm (in 35mm full format))

It is too long for digiscoping, it loses the clarity, portability and control that a normal DC gives.  As always, whatever which model of DC, lenses of NOT longer than 30mm is better.

I'm interested to know why you say this is a Crested Goshawk. I thought that it was an adult Besra, based on the small bill and the underpart patterning.

Nice pictures, by the way - I wish I could get a view like that!

Crested Goshawk's cere show more yellow, Besra’s cere show some green inside green.
And the underpart patterning of male Besra is more orange and vague than Crested Goshawk.

I think it is likely a Besra based on the shape. Possibly even this bird photographed there before.
