Bird A, a scruffy young blackback, has obtained a tasty piece of sashimi.
Birds B and C, a pair of big, mean, adult blackbacks, see no good reason for him to keep it.

Why the tech specs? I was a bit disappointed with the shots I got at Karori on Friday with my zoom - Canon EF 75-300 kit lens. They were not as sharp as I would have liked them to be, and I was trying to work out whether it was a case of operator error, or whether I was justified in blaming the gear. So I went to Oriental Bay to shoot feathers.
Looks like operator error to me. These are fine.
More specifically, the autofocus on this zoom is slow and doesn't work so well in low contrast conditions, like, for example, under a forest canopy. Having the aperture wide open exacerbates any problems with focussing, and when one's subject is a critter that just won't sit still, increasing the exposure time is not a good option. Also, using a flash just seems rude. Solution 1 seems to be: Get the focus approximately right, push the button lots, and hope the critter is at the right distance in at least some of the frames (Digital rocks!). Solution 2 is: Find well-lit wildlife.
