A series of 'm-ter-chick' calls and some purring from a bird in burrow G11, a chamber inside a stone wall. Calling induced by playing a short burst of purr calls from another bird. The purring from this individual indicates it is male. First of four recordings of this individual. One modification made to the recording: the removal of noisy portions at the start and end, so the remaining calls are not the full sequence. Length of gaps between calls not altered. Original WAV files available on request.
