What are some strategies animals use to attract and select a mate?

Sounds, movement, behavior, colors

Most animals are selective about who they choose as a mate.

They want to pass certain traits on to their offspring.

There are many strategies of how organisms find mates.

I see a bird spreading its wings and dancing, a frog making calls, a bird giving an insect to another bird, a bird building a structure out of grass, and small creatures glowing.

A behavior is the way an organism reacts to other organisms or to its environment.

Animals attract mates by communicating in a variety of ways, including the use of sound, light, chemicals, and body language.

Often times animals compete with others of the same species for a mate.

Sometimes animals even bring gifts to each other in hopes of getting the attention of one another.

Most animals have specialized behaviors that help them find and attract mates.

Male mule deer, become very aggressive towards each other when competing for a mate.

Peacocks compete by showing off their feathers.

Male frigate birds inflate their throat sacks when competing for mates
