Robin Feeding Frenzy The End! Click for large photo. Sure, he might have been hungry and swallowed the worm for his own lunch, but he could have done it for the kids! Baby robins don't have mouths big enough to eat a whole worm. So parents eat foods themselves and then regurgitate (throw up) small pieces for the babies. Baby robins love earthworms and larvae, but adults also like fruits and other tiny animals like beetles and spiders. Next time a robin is poking around your lawn, look carefully at what it picks up in its beak! More Robins for Kids
