Watch say a kookaburra pick up an item of food, raise its head and point its beak upwards to juggle the item into the best orientation, then swallow. Watch an Ibis foraging - like the Straw-necked ones in our local park, when the lady who feeds galahs on her lawn adjoining the park, chases the Ibises away from there. I assume an Ibis is not stabbing the turf just to strengthen its' neck muscles. Presumably it sometimes finds an item of food. But it doesn't lift its head. Just keeps looking down - beak pointing down - as it locates the next target. So how does it get that item of food up that long beak to swallow it, while the beak is pointing downwards? Any anatomist out there with the answer?
