What's in the issue

One of the best conservation stories of recent times in Britain concerns the chough, that delightful cliff-haunting corvid. This week we trace its resurgence that’s been enabled by expert birdkeepers breeding and releasing choughs. And they’ve happily recolonised old haunts where they hadn’t been seen for decades, even centuries. We also have advice and updates on canaries, parrots and waterbirds (and DEFRA!). More unusually we consult an 18th-century book on the subject of bird diet (fascinating!) and get some very 21st-century advice on how birdkeepers can use AI software. Plus all the expected regulars.
