Feeling 4 o'clockish!

Is there a collective noun for long-tails?

It was about 4 o'clock and the light was fading when I got into the garden today. But I was there in time to see a group of about 12 Long-tailed tits chattering around the feeders in the apple tree. It's not a great blip technically, I know, but lovely to see and hear all these little birds so I thought I would share it with you.
