They're conning joe public into believing that lack of habitat is the reason for the decline in the small bird population. I can remember as a little boy seeing hundreds of house sparrows around the town. Nowadays lucky if you see a dozen. If I'm not mistaken house sparrows nest in roof spaces and out buildings. Not much demolition work going on here in fact the town is expanding. I.e. More houses. Watching spring watch this year they had a camera on a sparrow hawks nest and that preek packman was actually studying what Mrs sparrow hawk had been eating. Robin, dunnock, great tit, etc then he said oh look at this one it's a blue tit and you can tell with the feathering that it's a fledgling maybe one from the blue tits nest box that we have a camera on. Fckn unreal. Nothing to do with lack of habitat it's what's in the habitat that's the problem.
