'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 the afternoon at The Chase, still very wet underfoot in most areas, but at least it didn't rain. Added four species to my Essex year list; Greenshank and at last some migrants Little Ringed Plover (2), Sand Martin (6) and Willow Warbler (2). Also good numbers of Chiffchaff around today.
