Spring is when most birds build nests and lay eggs. If given a choice, birds choose to build nests with naturally found materials from native plants. They especially love the remains of tall, native grasses (unglamorously called "debris"). Some good ones for here are Bluestem, Indiangrass, Muhly, Sea Oats and Gramma (we have several native grasses in our landscape, the majority being Inland Sea Oats – birds love it!)
Pieces of yarn or thread are popular with birds. Just make sure that no piece is longer than 3-inches. Any longer and there's a risk they can get it tangled in their legs or around their bodies.
The materials that birds use for nest-building can
be almost anything that’s somewhat small, stringy and lightweight. Also, many
nests are cemented together with mud, so it’s good to have water and/or mud
nearby. (It doesn’t have to be very conspicuous, or even in your own yard –
birds will find it!) A bird might
make over a thousand trips with beaks-full of mud, twigs, grasses, leaves or
whatever, at the start of nesting season.
Two of the most used natural materials are cotton and feathers.
Often these are used to fill, blankets, pillows, jackets etc. If you have an old, worn-out one of these taking up space, rip it a little and leave it outside. Birds will find this "gold mine".
Another natural material birds love is fur. When we
comb our dogs we’ll save the fur. Then we put it in something like an old wire
suet basket, hanging it from a branch. We’ll see all kinds of birds pull out
strands of fur to take to their nearby nests. Later, if we’re lucky enough to spot
a nest, we’ll carefully inspect it and may find several tiny bird eggs nestled in our
pets’ fur. Nice!
At first glance, used drier lint or drier sheets look fine as nest material. Avoid them however. Many laundry detergents contain stuff that's harmful to baby birds, so dispose of them some other way.
There are, clearly, lots of materials that can become nest ingredients. The key is to let them find it - just place it where they might be.
