Back to this week's update.

Big Gulp
This robin has just picked a mulberry with his beak, but his tongue will help him finish the job. Look closely: The robin's tongue is pointed at the tip and wide at the back, like an arrow. Gravity will help him toss the berry to the back of his tongue. Then the wide part of the tongue helps push the berry down the robin's throat as he swallows. See both photos on this page for the whole big gulp!
