Bird with obvious brown washed broad tail band, but otherwise very pale and showing snowy white outer primaries. It is hoped for that such white birds like this will be banded more often in future and of course it is very interesting to follow this individual over the years to see how the pigmentation in the outer primaries will develop and if there will be any correlation between this white plumage in 1st cycle and extent of grey in the primaries.
