'Bumbarrel' is an old name for the Long-tailed Tit, everyone's favourite garden bird. And the reason they're called that is for the shape of their nest. It's almost spherical, with a little hole at the front, and made from a special weave of moss, lichen, spiders' webs and feathers.
Spent a few hours on the reserve today. And the main difference to yesterday was the afternoon Short-Eared Owl show, after counting five yesterday today I only saw one! The weather was very similar with a sunny end to the day, although the wind was a little stronger and colder. So, I took a few common bird pics.
