I've just been going through my bird records and was reminded of the huge starling roost at Gretna I saw about this time last yr. It was quite possibly the highlight of an exceptional birding weekend (on the Hebs) yet I haven't been able to even guess at the number of birds involved.
Is anyone aware of any attempts to estimate the flock size? (perhaps a local bird report might help). It's by far the largest flock I've seen of anything but I couldn't begin to guess at the flock size. On a quick Google search I came upon a figure of 100,000 or so by late October 2007 but it acknowledges numbers were building and there is clearly many more later in the season. Grateful for any help.
