The beautiful Black-throated Sparrow (Amphispiza bilineata) calls are very quiet and very high-pitched (7500+Hz), making them difficult for some observers to hear. They have two songs: one is a delightful twinkling ramble, also sung very quietly. Both the calls and the song are on this sample, recorded 1/17/99 north of Phoenix, with the Telinga mic from only 20 feet.

The second song is the spring breeding song. This one was recorded near Sedona, Arizona, 5/22/99
