A quick video of a tame robin feeding from a guy’s hand. We have a robin like this in our garden – these little birds have balls of steel and will site quite happily on your hand until they have finished eating.
We find that suet is their favorite food, preferring it even to meal worms. They get as much as they con in their beak and take it back to feed the chicks in the nest. Once the chicks can fly the adults show then where to find the food.
