I posted the other day about the scaly thrush hunting for worms, and today I was amazed at how quickly they swallow the worms. The camera I use takes about 10 frames per second. And it took 15 frames from the time the bird bites the worm to the time it finishes swallowing, so in about 1.5 seconds. The worm was a large, fat worm by any standard. What kind of mechanism does this bird use? I imagine that it uses its tongue to push the worm into the mouth, but I am not sure. It is a mystery.
