No special tricks here. Just careful use of filmic reconstruction and not using the highlight reconstruction module (or in mode “reconstruct in Lch”) to remove as little information as possible. No selective masking, just make sure the tone equaliser mask is about correct for the zones you want to change (here: not clipping in the blacks)
But for the top of the white band on the wing, there’s not much you can do: at the best of times it’s a low contrast area, and it has at least two hard clipped channels.
Also, you only have so many levels to play with, you can either go for general contrast in the midtones (compressing the highlight and shadow detail) or for more detail in shadows and highlights (lowering overall contrast). Adding local contrast only helps up to a point. Personally, I often prefer somewhat less global contrast and better detail, but that’s a matter of taste (and also depends on the subject).
