OK, who hasn’t seen the suggestion to put scraps of yarn, twine, string and even human hair out for the birds during nesting time? In principle, it sounds like a great recycling idea. Make use of the little bits and pieces that would normally be thrown out and help the birds make sturdy and comfy nests for their eggs and hatchlings. And, how fun is it to see bits of color in the nests?
Our neighborhood birds never seemed too interested in our offerings. Thank goodness they were so much smarter than us!
Unsafe Bird Nesting Materials
A Facebook posting from the folks at Carolina Waterfowl Rescue quickly educated me that this act of kindness is anything but kind to our feathered friends.
Our good intentions have led to some horrendous outcomes.
Every year, the rescue organization takes in baby songbirds that have terrible injuries from these good intentions. The fibers may tangle around the bird’s legs, neck or wings. They act like a tourniquet and cut off the blood flow and cause injuries that can lead to loss of limbs and even death.
Birds and other animals can choke and have internal obstructions from eating the string.
If that’s not enough reason to not offer string-like fibers as bird nesting material, I have seen several mentions of birds getting trapped in their nests. The fibers get wrapped around the birds and literally tie them into the nest.
Think those fuzzy bits of drying lint would make a great option? That too is a bad idea. When it gets wet, it loses its shape and can leave holes in the nest. Additionally, the lint dust is bad for birds. And, if that wasn’t enough to keep you from using dryer lint for bird nesting material, think about the bleaches, laundry softeners and other chemicals that we all use to keep our clothes clean. Doubtful any of that stuff is bird-friendly.
Safe, Natural Bird Nesting Materials
So, now we know; yarn, string, twine and human hair is not appropriate nesting material for birds.
What can we offer birds as nesting material?
Here’s a list of safe suggestions for bird nesting materials.
1. Plant things in your garden that produce fluffy seeds. Cattails are a good choice. Milkweed is an even better one. Make your own edible butterfly garden with milkweed. The butterflies love it and the birds can use the fluffy seed heads. Honeysuckle and clematis are other lovely flowers that produce fluff useful to birds building nests.

2. When you start filling this year’s hanging baskets, offer the birds the worn-out coco fiber linings as bird nesting material.
3. Natural fibrous materials like sphagnum and Spanish moss make bird great nesting material. The focus here is on natural fibers. Don’t dyed, chemically preserved or otherwise chemically treated materials. (female chaffinch gathering moss for its nest photo from Nick Goodrum.)
4. Doing any spring cleaning this year? Perhaps you have an old down jacket, pillow or quilt that has seen better days? Recycle the feathers by providing your backyard friends with some natural nesting materials. (While the folks at the rescue did not say so, I’m thinking those colorful dyed craft feathers would probably not be a good idea here. I also wonder if the item has been dry cleaned, if it would be better to not offer it to the birds as there are harsh chemicals used in the dry cleaning process.)
5. Natural fiber quilt batting makes good nesting material too. Scraps of
wool or cotton batting cut into 3″ – 6″ strips provide a safe and comfy nesting material. Several folks mentioned using strips of cloth. I wouldn’t. Too many threads that could unravel and become a threat.
UPDATE: Thanks to Sharon, I am removing the suggestion of offering wool scraps as nesting material. Apparently, it can felt in warmer temperatures.
6. Animal fur. Do you have a fur baby? When you brush them, save the loose fur for your bird friends. Just don’t share pet fur that has been treated with flea dips or other insect repellents.
7. Yard debris. Pine straw, wheat straw, small/tiny twigs (anything under 4 inches is particularly useful to most backyard birds) and even grass clippings (untreated with chemicals) make great natural bird nest material. (Kaarina Dillabough graciously shared this lovely robin photo)
