What Birdseed Do Finches Eat? The Complete Guide

Finches thrive on a diet primarily of small seeds, especially Nyjer seeds and white proso millet, supplemented with occasional greens and insects, making a specialized finch seed mix ideal. Understanding what birdseed do finches eat is crucial for attracting and nourishing these delightful birds in your backyard.

Understanding the Finch Diet

Finches, with their small, conical beaks, are specialized seed eaters. Their diet in the wild consists primarily of small seeds, gleaned from grasses and other plants. Replicating this diet in a backyard setting is key to attracting and maintaining a healthy finch population. The success of your finch feeding station hinges on providing the right type of birdseed.

The Power of Small Seeds

The size of the seed is critical. Finches prefer seeds they can easily crack and consume. Large sunflower seeds, for example, are generally too big for their delicate beaks. This is what birdseed do finches eat comes down to—small is best.

The Finch Favorites: Nyjer and White Proso Millet

Two types of seeds are especially attractive to finches:

Nyjer (Thistle) Seed: Also known as thistle seed (though it’s not actually thistle), Nyjer seed is an oilseed that is rich in nutrients and highly palatable to finches. It has a high oil content that is particularly beneficial during colder months. Specialized finch feeders with small ports are needed to prevent this tiny seed from spilling.
White Proso Millet: This is another excellent choice and a major component in many finch-specific seed mixes. White proso millet is highly nutritious and readily accepted by a wide variety of finch species. It can be scattered on the ground, offered in platform feeders, or mixed with other seeds in a hopper feeder.

Finch Seed Mixes: A Convenient Option

Commercial finch seed mixes are readily available and typically contain a blend of Nyjer seed, white proso millet, and other small seeds such as canary seed and flax seed. These mixes provide a balanced diet and are a convenient way to ensure your finches get the nutrients they need. However, pay attention to the ingredients list. Some cheaper mixes may contain fillers that finches won’t eat.

Beyond Birdseed: Supplementing the Finch Diet

While seed forms the core of their diet, offering supplemental foods can further enhance their health and well-being.

Greens: Finches also enjoy fresh greens, such as chopped lettuce, spinach, or dandelion greens.
Insects: During the breeding season, finches will also consume small insects to provide protein for their young. You can offer mealworms or other small insects, especially during nesting season.
Grit: Small pebbles or grit help finches digest seeds more efficiently. Commercial grit is available, or you can offer finely crushed eggshells.

Choosing the Right Finch Feeder

Selecting the appropriate feeder is as important as selecting the right seed. Finch feeders typically have small ports designed to dispense Nyjer seed and other small seeds. These feeders help to prevent waste and keep the seed dry.

Common Mistakes When Feeding Finches

Using the wrong type of seed: Avoid offering large seeds or mixes that contain a lot of filler.
Not cleaning feeders regularly: Dirty feeders can harbor bacteria and mold, which can be harmful to birds.
Offering stale seed: Seeds that are old or moldy are not nutritious and can be harmful. Store seed in a cool, dry place to prevent spoilage.

FAQ Section: Understanding Finch Feeding

What kind of birdseed attracts the most finches?

Nyjer seed is almost universally appealing to finches and is the single most effective seed for attracting a variety of finch species. Pairing this with white proso millet in a mix will ensure a diverse diet and attract even more of these beautiful birds.

Can I feed finches sunflower seeds?

While some larger finches might occasionally crack open a sunflower seed, they are generally too large for most finches. Offer sunflower chips or hearts as an alternative, or stick to smaller seeds that are easier for them to manage.

How often should I refill my finch feeder?

Check your finch feeder regularly and refill it whenever it is low. The frequency of refilling depends on the number of finches visiting your feeder and the size of the feeder. A clean, consistently full feeder encourages regular visits.

Is it safe to feed finches bread?

Bread is not a nutritious food for finches and can even be harmful. It offers little nutritional value and can fill them up without providing the essential nutrients they need. Stick to seeds, greens, and insects for a healthy finch diet.

Do finches eat suet?

While finches primarily eat seeds, they may occasionally sample suet, especially during colder months when they need extra energy. Choose suet cakes that contain seeds and nuts to appeal to their preferences.

What is the best way to clean a finch feeder?

Clean your finch feeder regularly with hot, soapy water. Rinse it thoroughly and allow it to dry completely before refilling it. Regular cleaning helps prevent the spread of disease and keeps your finches healthy.

Can I attract finches to my yard without a feeder?

Yes, you can attract finches to your yard by planting native grasses and wildflowers that produce small seeds. Providing a source of fresh water is also important. A combination of natural food sources and a feeder is the most effective approach.

Are there any seeds that are toxic to finches?

Avoid feeding finches seeds that are treated with pesticides or herbicides. Also, avoid offering salty or seasoned seeds, as these can be harmful.

Do finches eat fruit?

While seeds are their primary food, finches may occasionally nibble on small pieces of fruit. Offer small pieces of berries or chopped apple as a treat, but don’t make it a staple of their diet.

How can I prevent squirrels from eating the finch seed?

Squirrels are notorious for raiding bird feeders. Use squirrel-resistant feeders or baffles to prevent them from accessing the seed. Placing the feeder in an open area away from trees and shrubs can also help.

What is the best time of year to feed finches?

Feeding finches year-round is beneficial, but it is especially important during the colder months when natural food sources are scarce. Consistent feeding throughout the year will help maintain a healthy finch population in your area.

Should I provide water for finches?

Yes, providing a source of fresh, clean water is essential for finches. A bird bath or shallow dish of water will be greatly appreciated, especially during hot weather. Ensure the water is clean and replenished regularly.
