观察细节

Three birds all confirmed by vocalizations - first bird giving "breer" calls on north side of first pond, seen and photographed. An additional two birds located together about 600 meters away, one on one side of the trail singing "free beer" repeatedly and another one in shrubs behind us giving "pip" and "pweew" calls. Both heard and visually located at the same time, but could only photograph the one singing. Photos and audio attached.
