I am not a wildlife photographer at all, don't have the kit here for it so don't usually bother! We have a lot of Red Kites hanging around camp at the moment, feeding off the scraps and sometimes getting brave enough to swoop down and take the food straight from your plate! Having seen the post about the Red Tail Hawks I thought I'd have a go at getting a shot.
Anyway, I only have a crappy 28-135mm zoom here so excuse the quality, this is not cropped so that should give an idea how close they get! Like I said, not really something I would bother with normally but quite like the way it came out.
