LBBG 1cy E169EAugust 06 2004 Nachtegalenkeet - Maasvlakte, the Netherlands.

A bird ringed left red E169, right yellow E. An individual illustrative for 1cy LBBG with second generation feathers. Note the location of these feather, unlike what one would expect when an ordinary sequence was followed: lower scapulars and third greater covert replaced in the left wing.
