'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.
Walked the seawall from RSPB's visitor Centre to the landfill site and back. At least three Willow Warblers singing, four Sedge Warblers and seven Cetti's Warblers. Added to this Chiffchaff, Wren, Dunnock and the sounds of Lapwing and Redshank made for a pleasant walk. In the field in front of the serin mound were four Wheatears two males and two females, while a fifth male showed well on the landfill trail. Skylark and Meadow Pipits were in fall song as I stopped to take in the views from the top of the landfill. Out on the river there were 18 noisy Common Terns feeding just off Aveley Bay.
