Hummingbird’s Forked Tongue

Some video clips showing Ruby-throated Hummingbirds eating sugar water from a hummingbird feeder that has a clear tube. The tongue is forked or split - the hummingbird extends it into the tube, opens the split tongue to capture sugar water -closes the tongue - then the tongue filled with sugar water returns into the hummingbird’s bill where the food is released to be swallowed.
