Yes I sometimes find old birds' nests -long abandoned and fallen out of a shrub or tree. I take them home and have a look at the building materials. This is what I found so far:
Horse hair
Sheep's wool
Badger hair
Grasses
Baling twine (usually well-worn looking twine)
Soft fur (which could either be moulted dog or cat fur)
Moss
Human hair (or something that looks like it.)
I always comb out my hair outside on the lawn in Spring and early summer, and any loose hairs get balled up in my hands and put on the grass, so some of those human hairs could have been mine!
On dog walks in the past I noticed many people had combed out their shedding long-haired dogs on walks, presumably so as not to get their furniture and carpets too furred-up at home! Birds love this.
