I saw this female today (together with the clearly smaller male). I wonder what can be said about her age. Is a 2nd/3rd plumage? It is a subadult? I'm struggling with the moult. What I see is moulted P1 to P3 ¿P4?, and I'm not really sure about the moult state of secondaries (8,9 ¿5?) and tail (any?)

subadult, new inner primaries are adult type so already third or fourth generation or later, in northern birds sometimes 5th generation or later
