Photo 18: fuscus-type LBBG 2cy, May 29 2000, Naaktstrand Maasvlakte, the  Netherlands. 

2cy LBBG with some features tending to fuscus: all feather tracts (including remiges) are completely second generation. Bill and legs containing much and bright yellow.
This combination is strange for a third type. During spring 2000 we only saw two birds showing complete second generation remiges, demonstrating the oddity of the depicted bird.
