NOTES: (single song phrase and swee-you call notes) -SBA 08 Oct. 2002 Location of recording unknown. There are three possible locations; Yuba Pass, Bear Valley, or Jones Valley, all CA locations, US. Yuba Pass info: USA, CA, 3km W of Sattley, Latitude: 39 38'N, Longitude: 120 30'W, Altitude: 2010m Jones Valley Info: USA, CA, 16 km SE of Loyalton, Latitude: 39 35'N, Longitude: 120 07'W, Altitude: 2100m Bear Valley Info: USA, CA, Sierra County BNA: Both the male song and a call is heard. The call is described above as the swee-you call but I don't know what the equivalent of that would be in the BNA. CZ 30/07/2004. [I believe that these calls are examples of the "too-ee-oo" call described in BNA. There are also two songs, but I cannot determine if there are mimetic elements due to the low quality of the recording. Quality changed from 2 to 3-2 - 4 February 2005].
