4 Common Materials That Could Be Harming Your Backyard Birds – And What to Provide Instead
From dryer lint to loose yarn, these damaging materials could be hiding in plain sight
Whether you're a keen birdwatcher or you just love welcoming wildlife to your backyard, you're likely doing plenty to make the space as bird-friendly as possible. What you might not have considered, however, is the harmful nesting materials that could be hiding in plain sight.
From string and yarn to pet hair and even dryer lint, a wide variety of materials can end up in your yard and become detrimental to wildlife. Many are toxic to birds (like plastic fibers), while others can pose a choking hazard.
Below, we ask experts to delve into the harmful nesting materials which you're most likely to find in your backyard – and how you can tackle these to help garden birds in the summer.

Any pet owner will know that it's practically impossible to prevent dogs and cats from shedding – but it's crucial to ensure that minimal pet hair ends up outside.
Loose pet hair might seem like a harmless material when it comes to wildlife, and some birds will use it to line their nests. However, it can be dangerous for a number of reasons.
'Soft dog hair can be used to line nests; however, if the hair is long or has a high tensile strength, it can become entangled around birds and cause injuries,' explains Dr. Pilar Fish, Senior Director of Zoological Advancement and Avian Medicine at the National Aviary in Pennsylvania.
'Plus, if dogs are treated with topical flea and tick products, their hair can pose a potential problem if ingested by fragile birds and chicks.'
Dr. Pilar Fish serves as the Senior Director of Zoological Advancement and Avian Medicine at the National Aviary. She has 21 years of experience leading the National Aviary’s veterinary department and advancing avian medicine on a global level. Dr. Fish has taught hundreds of interns over the years and collaborated with zoos and rehabilitation centers around the world, sharing her expertise and cutting-edge advancements in avian medicine.
2. Dryer Lint
It's not uncommon to find dryer lint in your yard, but it can become a particularly harmful nesting material: since it easily absorbs water, it can cause bird nests to collapse in wet weather. It can also contain harmful chemicals from laundry detergent and fabric softener.
'Dryer lint may have leftover residue from chemicals found in laundry detergent,' says Holly Latteman, Director of Science & Research for The Dawes Arboretum in Newark, Ohio.
'These chemicals might be common for humans, but they are uncommon for birds – and they can cause problems if used in nests.'
Holly Latteman received her Bachelor of Arts in Zoology, Sociology/Anthropology, and Environmental Studies from Ohio Wesleyan University in 2017, going on to earn her Master of Science in Environmental Studies from Ohio University in 2019, where her research focused on black vulture range expansion and human-wildlife conflict. Holly currently serves as the Director of Science and Research at The Dawes Arboretum, where she leads the living collections, plant records, herbarium, and nursery.
3. String and Twine
Gardening twine might be a staple in most backyards, but birds can find themselves tangled up in long strands or loose ends.
'String or plastic can become entwined around birds’ bodies or legs,' explains Dr Fish. 'Chicks are also at risk of getting entangled in fibers or eating fibers.'
To help prevent injury, experts recommend conducting a quick yard check to identify hazards like these.
'It's best to clean up any fibers from your yard that birds might see as possible nesting material and allow them to collect natural items such as sticks, moss, or grasses,' advises Lisa Kelly, Animal Care Supervisor at Teatown Lake Reservation.
Lisa Kelly is the Animal Care Supervisor at Teatown Lake Preservation, a 1,000-acre non-profit nature preserve dedicated to inspiring lifelong environmental stewardship. Lisa has been at Teatown for nearly two decades and is experienced in handling and caring for wild animals of all kinds, including turtles, birds of prey, squirrels and more. She is especially passionate about educating people on how to coexist with wildlife and discouraging the practice of keeping wild animals as pets.
4. Plastic
No matter how often you tend to your yard, you might find that trash and plastic waste still appears – and it could be causing serious issues for wildlife.
'Any kind of plastic item can be harmful,' says Steven Corcoran, CEO of Lawn Love. 'One of the biggest concerns is that it poses a major choking hazard.
'When used as a nesting material, however, it can cause a lot more heat to be retained which can overheat eggs and harm baby birds.'

The Best Natural Nesting Materials to Provide Instead
Once you've done your best to remove hazards from your yard, you might want to provide some alternatives – and this includes plants.
'The biggest thing I’d recommend is to see what’s native to your area,' says Holly. 'Native plants will provide birds with what they need to thrive in their natural environment, and you can always grow them around your bird feeder.'
You can also make use of twigs, moss and grass clippings.
'Birds consistently use grass clippings to nest,' Holly adds. 'Consider leaving the clippings after you cut your lawn rather than picking them up. You can also gather some small twigs, bark or milkweed fluff and put them near your bird feeder.'
