Vocal Yellow-browed Warbler...

While walking past the Lifeboat slipway, I heard a Yellow-browed Warbler calling. In fact it continued to call for about 30 minutes, enabling me to sound-record it. Oddly, there was sometimes an additional note included with the typical 'tseeooeet' call (see sonogram below and listen to call via player).
