In the fall and winter months the robins will gather in large flocks to roost in trees; also to find and eat berries. If the robins eat lots of honeysuckle berries, they can become intoxicated.
In the mornings the robins will hunt for earthworms. They find earthworms by sight; they will run or hop along and stop on lawns, looking for the worms. The robins can get poison if pesticides are used on lawns. They also like insects and some snails. Later in the day they will look for more fruit and berries to eat.
