This large flock of Starlings has been gathering together in small parties to make one huge group to roost together in central Brighouse for at least a few weeks.
Thank you to Annie Honjo for posting her video on You-tube.
We were there this evening 4.15 to 5.00pm, along with eleven other people amazed by the spectacle.
A Sparrowhawk appeared twice but didn't seem to catch a Starling, though it was definitely trying!
A spontaneous round of applause went up when the birds finally settled into the trees.
The finale is when the trees appear to suck the flock out of the sky.
If you want to see it, go to the car parks at the bottom of town near the double-towered old flour mill.
