Yep, this is a great way to help. I love providing nesting material. I put out a 'feeder' with various materials; brushings from my cats (loved by the chickadees), raw (unprocessed) cotton, feathers and loose coir (if I can find it...It's hard to find loose around here...but if I DON'T offer it the Crows have learned to pull up my coir plant pots, unwrap it from the plants rootball and take those! Erk! Boy was I confused what was happening to my plantings until I caught one in the act!) Each bird species seems to have a specific preference so a nice variate of options is nice.
