The Merlin is a falcon that relies on speed and agility to hunt for prey, which is mainly small birds and large insects. Merlins often hunt by flying fast and low, typically less than four feet above the ground, trying to take prey by surprise. Merlins can be aggresive and have been known to attack other birds of prey they may encounter, including eagles.
