Spontaneous vocalizations from what are initially unseen crows. The birds eventually come into view when they take flight and subsequently land in trees across the valley. At this point (the third segment), the recording improves over the initial segments and a greater variety of vocalizations follows as well. There are 4-5 birds vocalizing. This recording occurred from about 0930-1006 hrs. ML: 250 Hz AUHipass filter applied in soundBlade HD to the first two segments. 75 Hz AUHipass filter applied in soundBlade HD to all other segments. Other Behaviors: Perch. Habitat: Montane, Evergreen Forest.
