Podrobnosti k pozorování
I stopped on the path before getting to the first stone bench leading to the water pump and green cattle gate near the crest. I was just standing and listening as there was no movement or sounds. Facing south, I heard the flight rattle from the west going east in front of me i.e., the south side of the path. The rattles continued the entire flight. Rattles are reasonably, evenly spaced groups of about 6-7 descending series of mechanical calls in the 3.5 to 5.5 kHz range. Comparitive to the LALO that has less consistent spacing, often has 2-3 note segments, and lower high kHz. Location https://maps.app.goo.gl/kmQYEydawD66CqWM6
