Animal species have complex forms of communication. Ants send chemical signals secreted from gland to share information about food and enemies with other members of the colony. When honeybees discover a source of nectar, they return to the hive and communicate its location to the other worker bees through an intricate dance that signals both direction and distance. Male songbirds of various species sing in the spring to attract a female male and also to warn other males to stay away from their territory to avoid a fight. Dolphins talk to each other at great depths of the ocean by making a combination of clicking, whistling, and barking sounds.
