Answer:
Falcons, herons, and parrots are similar in that they are all types of birds. They are also all known for their hunting and fishing abilities, although they use different techniques. Falcons are known for their swift flight and ability to catch prey in mid-air, while herons are known for their long legs and sharp beaks which they use to hunt for fish and other small aquatic animals in shallow water. Parrots, on the other hand, are known for their intelligence and ability to mimic sounds and speech. Additionally, all three types of birds have strong, curved beaks and sharp talons or claws, which they use for catching and holding their prey.
