Visual, Auditory, and Olfactory Sexual Selection Methods in Birds Inform Mate Choice by Serving as Indicators for Mate Quality

Visual cues give females information about the developmental success, nutrition, foraging ability, and genetic quality, while acoustic signals allow females to access the intelligence of males.
