Just 7 days of flying and looking quite confident. Juvies are identified by reddish coloring on the chest, head and by a stubby tail.
For those not familiar with this species, it is highly unusual to get this close to a nesting pair of STKs, so images of fledglings are not very abundant.
Nikon D3, 500mm lens, 1.4X TC 1/4000@f8, ISO 2000. Manual meter +2/3 off of the sky.
Looks as if I forgot to dial back the ISO after the sun came up!
Sharpness looks good, maybe he was a bit nervous considering the cramped claws. :) I would tone down the overexposed highlights and wish the angle were less steep.
