'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.
While going through my camera's memory card, I found this image which I took on Monday of the male Black Redstart which is still present on the foreshore off Ferry Lane, Rainham
Can you see the bird?......you can certainly see the debris!, a cropped image is below, which shows this cracking male a little better. For much better images have a look at Hawkys blog here.
The black redstart was first
reported to have bred in London at the Wembley Exhibition Centre in 1926 and
since then its population has fluctuated primarily as a consequence of man’s
activities within the urban fabric.
During and after the Second World
War the population boomed as a consequence of the Blitz. The bombsites of the
City provided ideal habitat. Large areas of sparsely vegetated land between the
shells of buildings reflected the black redstarts optimum habitat on the scree
slopes of the Alps. In 1964 the population around Cheapside was in the region
of 16 pairs. However, with the regeneration of the Barbican, the population
crashed and although there is still the odd pair recorded in the City, the
black redstart’s distribution has gradually moved eastwards along the Thames.
In the ‘70s and early ‘80s there were still a few pairs breeding in the docks
and along the South Bank but as these areas were regenerated so the black
redstart’s numbers diminished.
There is a definite correlation
between the black redstart’s population in London and the likely loss of its
breeding habitat through regeneration. The primary aim of the London
Biodiversity Partnership’s BLACK REDSTART Action Plan is to reduce the adverse
impact of regeneration on black redstarts and ensure that its present
population is not only adversely effected by such schemes but, where possible,
