3cy+ May (male). Birds showing an arrested pre-breeding moult, where the retained feathers are of adult type, are possible to age as 3cy+. Note here that the AL contain two generations of feathers where the outermost is fresh with a dark brownish-black ground colour and a dark grey tip. The inner two (more than one year old) are pale medium-brown and show rather frayed tips. They are however similar in pattern and texture to the outermost feather and, more important, lack pale buff fringes. Note also one retained GC being much bleach and worn with rather similar pattern as the adjacent GC. [4611689]
