Cry of the curlew has given way to silence | Brief letters

It's not just Wales that is depleted of curlews (New initiative aims to save curlew from extinction in Wales, 22 November). Forty years ago, I regularly walked stretches of Hadrian's Wall in the Northumberland national park to the constant warbling of curlews, which was almost deafening. This year, I did some of the same walks in total silence. I was deeply saddened by the absence of the beautiful, haunting song of the curlew, which is, ironically, the symbol of the Northumberland national park.

Alice Renton makes a good point about solar panels in new-build homes (Letters, 23 November). But I recently saw an electric van with solar panels taped and tied to the roof and bonnet - the driver claimed it extended his range by five or six miles, even though it was just a rough-and-ready job. When will electric vehicle manufacturers start building solar panels into the bodywork?
