In April 2015 on the German island Heligoland I was trying (not very successfully) to snap pictures of Chiffchaffs catching low flying insects over a pond. Reviewing the photos I recognized that many of them (at least 5 of the ca. 30 Ind.) had strangely light-coloured feather-parts. Does anyone have an idea where this comes from?
