CZ 17/06/2004.[Two song-types are included here, typical examples of the "downslurred" trill of BNA (0:17, 0:31, 0:50, 1:21, 2:26, 2:46, 3:19, 3:59, 4:49) and a somewhat different trill that is probably the Arizona variant of the "upslurred" trill of BNA (1:07, 1:33, 1:45, 2:00, 2:13, 2:33 (decapitated), 3:00, 4:12, 4:33). The BEST part of this cut is probably that between 2:45 and 3:23. This represents S. a. evura based on range, which may explain why the "upslurred" songs differ from those pictured in BNA (based on California birds). Quality added (2-3, 1-2) - CAM - 6 January 2005].
