One of the highlights of Spring is the return of the dawn chorus. It's something I miss most about living in the country, having taken the sound for granted when I was younger. But it isn't as singular a time of year to hear birdlife as might be thought.
In 2013, I finally had the means to attend the course run by Chris Watson and Jez Riley French as part of the Wildeye school in Norfolk. There, I recorded a morning chorus as rich as any I have heard before, but this was in early December. I've had it sitting on my hard drive, with the intention of doing something with it, but think it best now to make it available for listening.
