Communication and Perception
The males sing from exposed perches in their respective territories. Males sing 1 to 3 song types, and their song is not directed solely at females; the males also use song to communicate with each other across territories.
The extent of black "bib" coloration on the throat and breast of male Harris's sparrows communicates rank. Males with larger bibs, regardless of age, are often perceived as higher ranked than males with smaller bibs.
Harris's sparrows perceive their habitat through visual, tactile, auditory and chemical stimuli.
Communication Channels: visual ; acoustic
