The calls of Sykes's and Booted Warblers
The calls of Sykes's Warbler and Booted Warbler, as described in the article of this title by Antero Lindholm and Tapio Aalto in Birding World 18 (9): 395-396, may be heard by clicking on the three links immediately below:

Sykes's Warbler 1 Call 1: the “zak” call of a Sykes’s Warbler, Karaoy, south of Lake Balkhas, Kazakhstan, 8th July 2005. A very short call lasting only one-hundreth of a second. Most of the energy is at about 4,000Hz.

Booted Warbler Call 2: the “dsrak” call of a Booted Warbler, Kurgaldzino, near Astana, Kazakhstan, 3rd July 2005. There is a weak pre-syllable, while the main syllable is longer than the “zak” of Sykes’s Warber. Most of the energy is concentrated below 4,000Hz.
