Tiny Nest made from hair

Made randomly with my own hair from brush....after getting rid of the damp washed hair tangles (its long).I found myself felting it with my fingertips and it turned into a little birds nest.
Here it is surrounded with soft feathers I found on the grass in a morning following shrill Owl and or Kestrel calls, and I wondered if there was a bit of a fight, as I can think of no other explanation of the loud calls and subsequent treasure.
