'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.
Over the bank holiday weekend I twice visited Rainham Marsh west, spending a couple of hours each time looking for the Wryneck without success. There were lots of Sedge Warblers 20+ along the footpath that cuts through the middle of the area.
A Cuckoo was singing on the adjacent silt lagoons, Swifts flashed by overhead and a Hobby was my first of the year.
At home in my garden I rescued an Angle Shades moth from my garden shed, while an Old Lady caterpillar was climbing a dandelion stem and a Carnation Tortrix was resting on foliage.
