I have not seen any activity as of yet. Will keep a look out. :) Hoping to see it used by any bird. Hopefully have it in a good spot.
Thanks for your review! Yes, it might take a week or two for the birds to find and start making use of it. You'll know even if you don't see the birds in the act, because the hair will be pulled through and hanging in long strands. I finally caught a tufted titmouse gathering some for its nest after several weeks of waiting. Near your feeders or bird bath and where there is easy escape to shelter in brush and trees is a good location for hanging nesting materials.
