Starlings are unlikely to feature in these pages often and I wouldn't normally bring them to your attention. A regular roost seems to becoming established at Venus Pool however and I for one, always find this evening activity one of natures spectacles.
Are they just doing it for fun? I think so and other species seem to be drawn into the proceedings although the Jackdaws didn't seem to be able to keep up with the manouvres. Capturing the spectacle is not easy due to the low light and obvious movement of the birds.
Here's an attempt - how many do you reckon? I would have estimated at least 5,000 birds - quite a sight!
