Photo 9: LBBG 3cy, June 16 2001, Missouriweg, Maasvlakte, the Netherlands. 

A pretty straightforward second summer (3cy) LBBG, although the upper-part moult is quite advanced (yet still not resembling a 4cy as in some (intermedius?) LBBGs. Second summer LBBGs normally show a grey saddle formed by mantle and scapulars. Here many of the lesser coverts are already moulted to adult-like feathers, so the extreme division between 2^nd generation coverts and grey saddle is lost. Active moult is continuing in the coverts: some inner and central median, some central greater and some inner and central lesser coverts are plain adult-like grey. One tertial has been replaced recently by a new adult-like feather which is grey centred with a large white tip. The bare part coloration is typical for 3cy LBBG.

The outer primaries are 2^nd generation, without tips and no mirror on p10, but there is a very small spot visible at the tip of p5 (but this is not uncommon on the innermost primaries). In the field the inner primaries and secondaries appeared to be 2^nd generation.
Note that the lower tertials, though grey, are already abraded.
