Feeding Bluebirds

A Complete Guide to Using Dried Mealworms for a Thriving Backyard Bluebird Population

Bluebirds are among the most beloved backyard birds, known for their vivid plumage and gentle presence. Attracting these iconic songbirds takes the right combination of habitat, nesting options, and most importantly—food. One of the best ways to support bluebirds year-round is by offering dried mealworms, a protein-rich treat that meets their nutritional needs and encourages nesting behavior.

Why Bluebirds Love Mealworms

Mealworms are a natural part of the bluebird’s diet in the wild. These insectivores rely on soft-bodied insects to feed themselves and their young—especially during breeding season. Dried mealworms are the perfect substitute, delivering essential protein, fat, and energy in a form that’s easy to store and serve. When natural food sources are scarce, such as during cold spells or rainy days, mealworms can be a literal lifesaver for nesting pairs and fledglings.

A Better Alternative to Live Mealworms

While live mealworms are commonly used, they can be hard to find locally and even harder to ship safely—especially during the heat of summer. Dried mealworms solve these problems: they’re shelf-stable, require no care, ship easily, and are significantly more affordable—nearly half the cost of live ones. Best of all, bluebirds accept them readily when introduced correctly.

How to Attract Bluebirds to Your Feeder

If bluebirds are already nearby, feeding dried mealworms is an excellent way to encourage them to stay and even nest on your property. Start by offering a small amount in a shallow dish or saucer placed in a visible location. Once bluebirds discover this reliable food source, you can transition to a bluebird-specific feeder with small entry holes that exclude larger, more aggressive birds.

A flat saucer placed on top of the feeder during the first few days can help draw the birds’ attention. After they associate the feeder with food, place the worms inside the protected compartment to give them a safe, consistent feeding spot. Over time, you can move the feeder closer to your viewing area, making birdwatching more enjoyable.

Benefits of Feeding Bluebirds Mealworms

Mealworms can:

• Encourage bluebirds to nest in your yard by providing a reliable food source

• Help incubating females minimize time away from their eggs

• Support nestlings with vital protein and calories when natural insects are scarce

• Offer energy during winter months, increasing bluebird survival rates

Watching adult bluebirds feed their fledglings at your feeder is a highlight of backyard birding. With consistent feeding, your yard could become a regular stop—or even a permanent home—for generations of bluebirds.

What If You Don't See Bluebirds Yet?

Keep in mind: if bluebirds aren’t already in your area, dried mealworms likely won’t attract them on their own. However, other insectivorous birds such as chickadees, titmice, nuthatches, and wrens will quickly find and enjoy them. If your goal is to host bluebirds specifically, pair your feeding efforts with the installation of nesting boxes, clean water sources, and native plants that provide natural cover.

How Much to Feed—and When

Mealworms should be used as a supplement, not a sole food source. Offer around 100 worms per feeding, once or twice daily—morning and early evening are ideal. This is enough to support a nesting pair and their chicks without overwhelming their natural diet or attracting too many competitors.

The Best Feeder Types for Bluebirds

The most effective feeder for bluebirds is a hopper-style feeder with 1½-inch entry holes. This design keeps the mealworms safe from larger, aggressive birds while still allowing curious bluebirds to enter and explore. Once a male bluebird claims a feeder, he will often defend it for his mate and offspring. Watching this natural behavior unfold in your yard is one of the great joys of birdwatching.

A Rewarding Routine for You and Your Birds

Feeding bluebirds dried mealworms isn’t just about bird care—it’s about creating a thriving backyard habitat. When you support bluebirds with the right food, shelter, and safety, you contribute to their population success while enjoying close-up views of their daily routines.
