Backyard Tip: Crushed Eggshells Are for the Birds

Many species, including tree swallows, eat crushed eggshells both for calcium and for use as grit.

When you make your breakfast eggs, save the eggshells! We can hear you asking: "What? Why?" The answer is they are a great addition to your bird-feeding program. Many different species eat crushed eggshells both for the calcium they provide to nesting females and for use as grit in the food-digesting process in the gizzards of seed- and insect-eating birds. Rinse out your eggshells, place them in a metal tray in an oven set at 325 degrees. Bake the shells for 20 to 30 minutes to kill off any bacteria from the domestic chickens that laid them, then crush the shells and spread them on a flat, open surface such as a sidewalk, driveway, deck railing, low roof, or patch of bare soil. Swallows, martins, sparrows, finches, bluebirds, and other backyard birds will visit this new offering.

  • I’ve been enjoying goldfinches eating coneflower/ echinacea seeds in my new pollinator garden! I will leave the plants out all winter for them if the seeds keep that long? Or should I deadhead and put them in a dry area? Im in CT and thought they migrated, but didn’t know they put in winter coats! What do they eat in winter without bird feeders?

  • Hi Gary, I will pass your question along to Birdsquatch next time I see him. He knows infinitely more about nocturnal wildlife than I do. Where do you live? That's pretty important in figuring out the answer. But the thief could be raccoons, deer, or flying squirrels. Do you live in the woods? Are there trees near your feeder, or must the culprit climb a shepherd's hook or pole? Dawn Hewitt, Watching Backyard Birds

  • Thank you, Dawn. I'm close enough to Ohio (Ann Arbor, Michigan) that I went ahead and took my tubes down and scoured clean all my bird baths. I won't put up my tubes this winter, just my trays and safflower only just to keep the bullies away for a while.
