Chemicals used for signaling between different species. Compare pheromones
In this type of mimicry a harmless signaler imitates a dangerous one. Compare
with Mullerian mimicry.
Reception that requires the receiver to be in contact with the signal chemical.
Compare with olfactory reception.
Exocrine glands have ducts to release substances outside of the body rather than
Chemicals produced by endocrine glands for release into the body which function
in feedback and control of behavior.
Incomplete behavior patterns that provide information about the activity a
particular animal is about to perform and act as a signal to others.
In this type of mimicry two dangerous species evolve the same signaling trait to
the mutual benefit of both. Compare with Batesian mimicry.
Reception of odors (smell). Waterborne or airborne chemicals can be detected at
a distance from the source by olfactory reception. Compare with Contact
Chemicals used for signaling between members of the same species. Compare
An intermediate stage of birdsong in which there are components of adult song
patterns but the overall song is still highly variable.
Information about the environment external to the signaler.
A behavior that once served its own purpose but has come to act as a signal
about that purpose is said to have become ritualized.
Frequent repetition of a signal behavior.
An early stage of birdsong in which the song has little or no structure.
Zahavi's handicap principle
This principle states that in order to be honest, a signal must be costly to the
