Media notes
Earnest vocalization of two males (and others) while courting a female. Song? Calls? Both??
Observation details
Conservative estimate (yes, really). Most concentrated along the west and north sides, with numerous nests under sides of the buildings across Washington and Davis Sts. and in many light fixtures as well (!). The full range of behaviors: pairs foraging together, two males courting a female (audio recorded), carrying food and feeding recent fledglings.
