Cretzschmar's Bunting Emberiza caesia
Napi Valley, Lesvos, Greece 39° 16' 33.0" N 26° 17' 07.9" E 20 May 2017 Territorial song from dry, rocky hillside. Song composed of short 1.1 to 1.3 sec strophes, alternating between higher and lower frequency series repeated at a rate of 22 per minute. Each strophe differing in type, composed of around 5 to 13 upslurred or downslurred elements, mainly on a level frequency, ending with a longer (or 'stretched') terminal element, which is occasionaly higher or lower in frequency. Double elements sounding like a single element to the human ear probably originate from both bronchi in the syrinx. Reminiscent of Yellowhammer. (Crested Lark in blackground, later in recording).
