Notas sobre o média
I was unclear about aging this bird with the remiges and upperwing coverts, so I reached out to Peter Pyle. This is his analysis: "SY on rects alone. In this case the molt limits are mostly within the lessers and between the lesser and median coverts (so a relatively restricted PF). The small buff tips to the medians (and to some extent some of the greaters) is a juvenile thing. The 3rd or so greater from the outside has been replaced accidentally. I call those 'wear clines' from the innermost greater outward, and among the tertials, as these are the exposed feathers when the bird is sitting."
Detalhes da observação
Estimated count. Widespread, but not a lot of song, perhaps because of the overcast. See analysis of a particular robin, below.
