No. Do not place dryer lint out for the birds. I know that several publications a few years ago put this out as a way to help birds and Ornithologist have been trying to undo this damage ever since. The fear is that the small dust that is present in lint will be dangerous for the hatchling’s lungs. We have many good alternatives here at the store. Nesting material wreaths, bells and cages can be filled over and over again with various refill packs that contain a mixture of strings, feathers, cotton, etc.
