Black redstarts in East London.......

Black redstart is a rare breeding bird in this country but there are a few pairs surprisingly in East London. I heard a male singing from a derelict site near the Three Mills studio in Bromley-by-Bow. They like industrial sites and thrive on the midges hat emerge from pools of stagnant water. They first colonised old bomb sites after WW2 and have kept a toehold in London ever since. I filmed this bird singing on migration a few years ago...not recently - we haven't seen blue sky like that in years!!!!!!!!
