A common female preference in birds related to sexual selection is what?

• A. Elaborate displays or strong territory defense as indicators of fitness.
• B. Preference for dull plumage.
• C. Preference for silent behavior.
• D. Preference for weak territory defense.

Answer: (A)

In birds, female choices often favor signals that reveal a male’s fitness or resource-holding ability. Elaborate displays or strong territory defense are classic examples because they show the male has the energy, health, and skills to perform costly courtship or defend a valuable area. These traits can indicate good genes or the capacity to provide for offspring, making them attractive to females who are selecting mates. By contrast, dull plumage, quiet behavior, or weak territory defense don’t convey much about a male’s quality or ability to invest in offspring, so they’re not as advantageous as mate indicators.
