A primary source of nutrition for many birds is nuts.This high-calorie food provides them with dietary fat, which can be especially welcome during the colder months. As nuts ripen, you can see the birds flying by, carrying acorns and beechnuts, as well as seeds of various kinds. Some birds are especially suited to eating nuts with their thicker, cone-shaped bills, which are shaped to help them crack open pods and seed cases. Northern cardinals (Cardinalis cardinalis), sparrows, grosbeaks, finches and woodpeckers are seed and nut lovers.
I had been lax in providing my yard birds with these culinary treats except for sunflower seeds and the seed pods in my yard trees. So one day early last year, I purchased a nut and seed holder and proceeded to give them peanuts, which are not actually nuts but the seed of a legume (Arachis hypogaea). This makes no difference to the birds like the Carolina wren (Thryothorus ludovicianus) of course.
I first tried peanuts in the shell and an occasional blue jay and tufted titmouse would stop by. However, they didn’t seem to want to put much time into removing the nuts from the shells and I didn’t really want the shells littering the ground either.
Then in the spring I put out some shelled peanuts from a container I’d bought for my own consumption and the avian visitors were delighted. Reading about peanut feeding informed me that I should avoid giving salted peanuts. I couldn’t readily find unsalted ones at the grocery store, so I began removing the salt, either by shaking the nuts in a paper bag or by washing off the salt.

Before they left for the summer, the yellow-rumped warbler (Setophaga coronata) and ruby-crowned kinglet (Regulus calendula) tried the peanuts, too. Sometimes I wondered if the kinglet was also not looking for insects around the peanut feeder.
My choice to provide nuts was a big hit; I was rewarded with a procession of individuals of varied species who came by to quickly gulp or carry off a tasty nut. Some are pictured below – they came at different times of the day.

The common grackles (Quiscalus quiscula) will sometimes break down the nuts (and are quite messy about it, compared to the chickadees and titmice), but they will also swallow the treats whole.
Others are intent on breaking the peanuts into smaller pieces that are easier to get down; this seems especially true for the smaller birds like the Carolina chickadee (Poecile carolinensis) below. Here we also see Riley, my banded Carolina wren, enjoying a treat.
The blue jays (Cyanocitta cristata) often gulp down some nuts quickly and then try to carry off several nuts at a time.
One good thing about the peanuts is that thankfully the starlings (Sturnus vulgaris) and brown-headed cowbirds (Molothrus ater) don’t appear fond of them (they gulp down the dried mealworms, however, as if that food is going out of style). One will occasionally sample a nut, but they never seem to want a second.
As time passed, I realized that the peanut feeding strategy was rewarding me with frequent avian visitors, but was also rather costly. In the autumn, I began putting out a less expensive fruit and nut mix. This has also proved very popular and various species of birds are willing to share space at the feeders. The chickadees especially will feed alongside others, like the house finches and Northern cardinal below.
Species that usually forage on the ground, like the white-throated sparrows (Zonotrichia albicollis), also make occasional forays to the nut feeder.
When the nut feeders are empty, it’s not uncommon to see birds sitting atop them; when they see me, some will call out, as if saying, “Hey, fill up that feeder, please!” And I usually accommodate them, especially when it is very cold, as has been the case the first days of 2018 – we have had a record-breaking stretch of days in which the temperature did not rise above freezing, an unusual occurrence for our southern state of North Carolina.

The nut feeders have also been very attractive to the resident Eastern gray squirrels (Sciurus carolinensis), one of whom has been VERY persistent in devising ways to get onto the feeders. Each time s/he succeeds, I change the position of the feeders or stumps and branches nearby. Currently, that clever rodent hasn’t been able to get up there. In compensation, I occasionally throw a handful of nuts on the ground.
So, not all the birds are “nuts” for nuts, but plenty of species think they’re mighty fine! They are definitely a worthwhile addition to the birders’ array of feeder offerings.
