Onion-like umbrel of purple flowers at end of bare stalk.
Fire up the zoom and look at the small bird on the stick below and leftish of the osprey nest. A new one to me.
Bird in nest. Suggestion of scaling on body and wing feathers, maybe even a hint of pale yellow / buff near neck, and the confused but defiant look in the eye suggest juvenile osprey. Dark something on breast a mystery to me.
