Male Fighting Behavior
In nature , fighting among males is rare , with males
instead preferring to display to one another . Why?
Some birds display infidelity (EPC) what benefits do each of the sexes
derive from EPC?
Evolution has developed a means to select the best males for reproduction
using display and non-contact behaviors for selection to prevent mortality
in populations that may need to have a specific number of individuals to
survive. The species survival may depend upon the survival of the male
population or the may need to insure a numeric strength. Of course my
answer is too simple for you need to have a great understanding of how
speciation works and the detail understanding of ecological concepts to be
able to fully understand the implication of your question. The second part
of your question needs elaboration for I am not sure of what you are asking.
Display is a way of resolving disputes, usually over territory, without
resorting to the stress and potential injury of fighting. However, fighting
is not uncommon, usually, but not always, when between males of the same
species ending before serious injury to either.
