I regularly sweep up clumps of moss, which grows on our roof, from the paved area outside our back door. The photograph below was taken about an hour after I had finished sweeping up the last lot. Through the patio doors from our sitting room there could be seen a regular drop, drop of moss from the roof above. The culprit is a jay, sometimes a pair of jays. I doubt they are collecting nest material at this time of year. Perhaps they are looking for insects. Or maybe its just for fun.
