NOTES: Adult (probably female) at and near nest. Two distince kacking calls were not recorded. Vocalizations on tape are shorter, mild alarm calls in response to my approaching her nest or position. She would only vocalize when I moved to there is mechanical noise from my feet and hands. Poor recording conditions with temp 100 degrees, wind rising to 20+ kt, and many crows.; The values for latitude/longitude were gotten from www.topozone.com 12Dec2001-LAS.
