NOTES: Other General Habitat: Brush hedgerow VISUAL DISPLAY: (notes from RRN 90-17-3) This cut includes long-eared owl wing clapping. Behavior seems to be most prevelent 1/2 hour after sunset. This behavior said to be part of courtship display. Birds flying overhead seem to flutter or give "moth-like" flight pattern. Slapping appears to occur on both up beat and down beat. BREEDING STATUS: Territorial.

ML Notes: The call also heard is the Advertising song ("hoo" notes), based on the BNA. CZ 12/01/2004.
