An example of a strong and powerful male michahellis. The head is nearly all-white and the tip of the bill turns white. The tail and all the tertials are completely juvenile. Moult in the wing-coverts and in the scapulars is in progress: the recently moulted rear lower scapulars show very neat and fresh broad white fringes and buffish centres. The upper scapulars were moulted some time ago and some those feathers have the buff- based centres bleached now. Furthermore, the white fringes are worn away in these feathers. In the rear lower scapulars two feathers are still missing and will be replaced for second generation scapulars. 
Several wing-coverts were moulted as well: the inner four greater coverts have been replaced for second generation feathers, while the fourth greater covert is still growing. In the median coverts #1-3 and #6-7 have been replaced. Lower lesser coverts #1-2 and #4-5 were moulted and as can be seen in the picture #1 has a clearly grey base-colour and was moulted very recently.  Four lesser coverts are replaced as well. There is no active moult going on in the wing-coverts.
