My favorite food exchange photo almost full frame. Alot of light, but I managed to get the mouse in on the action! Amazing to watch. It happens within 2 seconds, as soon as you hear them screeching, find the parent, and soon she will hand it off to one of the babies. I was lucky enough here to be fairly close. It all depends on how fast the babies catch up to her, which their skills get faster every day, so slowly it becomes impossible within 7 days to be in the right place for a photo.
