NOTES: BNA: Call types: "II", "III", "IV", "V (alarm)" LNS Note: Unbroken cut with internal recordist announcement gain change (MJA, 7Feb2005). Breeding status: TERRITORIAL PAIRED; Frequency of sound: NORMAL; General climate: ARID; Cover density: THICK; [This recording has five parts and four different vocalizations. The first part (0:07-0:32) begins with two of the "Zhee-Zhee-Zhee" calls of BNA (or the Type II calls of Atwood [1988. Ornithological Monograph 42]), followed by sets combining the "Ti-Ti-Ti-Ti" (Type IV) Calls with Scolds (Type I). The second part contains "Zhee-Zhee-Zhee" calls (0:32, 0:59, 1:04, 1:08), "Ti-Ti-Ti-Ti" Calls (series at 0:33, 0:35, 0:39, 0:41, 0:45, 0:47, 0:49, 0:51, 0:56), "Jit-Jit-Jit" (Type III) Calls (series at 0:37, 0:43, 0:52), and Scolds (0:35, 0:37, 0:40, 0:42, 0:45, 0:46, 0:48, 0:50, 0:52). The region between 0:56 and 1:07 appears to represent transitions between "Zhee-Zhee-Zhee" calls and Scolds. The third part contains primarily "Zhee-Zhee-Zhee" calls, but with four sets of "Ti-Ti-Ti-Ti" Calls and two Scolds between 1:35 and 1:44. The fourth part (separated by a stop-start at 1:53) has a single series of "Ti-Ti-Ti-Ti" Calls followed by a Scold. The fifth and final part (2:07-2:49) alternates between Scolds and "Jit-Jit-Jit-Jit" Calls. Quality changed from 2-1 to 2-1, 1-2 (but overloaded in a few places) - CAM - 21 December 2004]. Other Behaviors: Advertise. Habitat: Desert, Scrub.
