A vacant plot in Eastcliff must have something going for it, at least as far as the world of Spotted Thick-Knees is concerned. This morning, whilst out walking, I spotted no less than 12 of these birds sunning themselves in an area no bigger than 40m x 40m. There may have been more – I only saw the ones that were standing and I did not get too close for fear of disturbing them. I read that out of breeding season they form roosts of up to 70 birds, but this my first experience of this habit. R Hazell.
