I suspect the birds are knitting a nest in the rain spout above my window at work. I see them flying in there with long pieces of straw and grass. They must be rebuilding as we had torrential downpours over the weekend and a pile of nest making materials was on the ground below the rain spout when I came in yesterday morning.
YOu can see in teh above picture that it’s raining here again today. I wonder if their work will be washed away again.
A couple of weeks ago I scattered small bits of yarn (less than an inch long) in the wooded area behind our house for the birds to use in their nests. I noticed most of it was gone when I walked around our yard last evening.
