Summer SC* sp
Winter wp wp?
Young sp: The post-juv moult (conducted at two months old) includes the entire head and body, all RR (sometimes R1 is retained) as well as all LC, MC, and ranging from one-third to all GC. One-half to all TT are also included as well as occasional AL.
Young wp: It is unknown whether a winter partial moult is conducted. If so, it is likely to be limited to parts of the head and/or body.
Adult SC: The post-br moult (from Jul to Oct) includes the whole plumage. Some individuals arrest the moult of SS and/or underwing GC, thus showing two generations of feathers.
Adult wp: The pre-br moult (from Feb to May) includes some body and head feathers and occasionally RR.
No plumage differences.
