Siberian Chiffchaff

The last net round of the day at the sewerage works produced three 'Chiffchaffs' . These were the second, third and fourth of the afternoon and although the first two were typical olive/yellow and dull nominate collybita, the third was so pale and silvery it looked like a totally different species. A bit like the last few holes at The Open when the light is failing and the commentators say 'you can't tell from the TV but it's almost dark'; well, by the time I came to the pale Chiff it was, so forgive this underwhelming image taken without flash, to avoid false bleaching, but it doesn't capture just how dark it had got.
