What Do Blue Jays Eat and How to Feed Them?

Blue Jays (Cyanocitta cristata) are one of the most striking and intelligent birds you can attract to your backyard. With their vivid blue plumage, black necklace-like markings, and sharp crests, these birds stand out in any setting. But what really sets them apart is their complex behavior, intelligence, and broad diet. Understanding what Blue Jays eat and how to feed them effectively is key to attracting these beautiful creatures to your yard.

Understanding the Blue Jay’s Diet

Blue Jays are omnivores, meaning they eat both plant-based and animal-based foods. Their diet is highly adaptable, allowing them to thrive in diverse environments, from forests to urban backyards. Blue Jays are opportunistic eaters, meaning they’ll eat whatever is available, but they do have preferences.

Natural Diet

In the wild, Blue Jays feed on a wide variety of food sources. Their diet changes with the seasons and availability of food.

• Nuts and Seeds — Blue Jays are particularly fond of acorns, beech nuts, and other tree nuts. They are well-known for caching (storing) acorns, which helps regenerate forests. They have strong beaks capable of cracking open hard shells.
• Fruits and Berries — Blue Jays love eating fruits like cherries, elderberries, blackberries, and grapes, as well as fleshy fruits like apples and pears.
• Insects and Invertebrates — During the spring and summer months, Blue Jays rely heavily on protein-rich insects, including beetles, grasshoppers, caterpillars, and spiders.
• Small Vertebrates — Blue Jays occasionally eat small mammals, frogs, and birds’ eggs, making them controversial figures in some birdwatching circles.
• Grains and Cereals — They also consume grains, corn, and other cereal crops when available.
• Suet — Blue Jays enjoy suet during colder months for its high-fat content, which provides energy in winter.

How to Feed Blue Jays in Your Backyard

If you’re looking to attract Blue Jays to your backyard, providing a diverse range of foods is key. Blue Jays are bold birds and will not hesitate to visit feeders if they feel safe and see food they like.

1. Nuts and Seeds

• Acorns — Acorns are a favorite among Blue Jays, and offering them can mimic their natural diet. You can scatter acorns around your yard or in platform feeders.
• Peanuts (Shelled or In-Shell) — Blue Jays love peanuts, particularly when still in their shells. Offering unsalted peanuts on a platform feeder or in a peanut feeder can attract these birds quickly.
• Sunflower Seeds — Black oil sunflower seeds are another staple in a Blue Jay’s diet. These seeds are small but packed with energy, making them a great choice.
• Cracked Corn — Blue Jays are attracted to cracked corn, which is an inexpensive option for feeding them.

2. Fruits and Berries

• Fresh or Dried Berries — Offer fresh or dried berries such as blueberries, strawberries, or elderberries. Dried fruits work well in winter when fresh berries are not in season.
• Apple and Pear Slices — Blue Jays enjoy fresh slices of apples or pears, especially in fall.
• Grapes — Place small bunches of grapes in platform feeders or scatter them around your yard.

3. Suet

Suet is an excellent high-fat food for Blue Jays, particularly in winter when they need more energy to stay warm. You can purchase pre-made suet cakes or make your own using animal fat mixed with seeds, nuts, and fruit.

4. Mealworms

Live or dried mealworms are protein-packed treats that Blue Jays will eagerly devour. These are especially helpful to offer during the breeding season when Blue Jays need extra protein.

5. Grains and Cereals

Blue Jays will also consume grains like oats, cracked corn, and even stale bread. However, make sure not to overfeed grains as they are not the most nutritious option.

Best Types of Feeders for Blue Jays

When feeding Blue Jays, choosing the right type of feeder is essential to attracting and accommodating them. Blue Jays are medium-sized birds, so they prefer larger, sturdier feeders that can hold their weight.

1. Platform Feeders

Platform feeders are the best option for Blue Jays. These feeders have a flat, open design that allows Blue Jays to perch comfortably and access a variety of foods. You can spread seeds, nuts, and fruits on platform feeders, making them a versatile choice.

2. Tray Feeders

Tray feeders function similarly to platform feeders but are often mounted on poles or hung from trees. They are easy to clean and refill and allow Blue Jays to access a wide range of food.

3. Peanut Feeders

Peanut feeders are specifically designed to hold whole peanuts in shells. They have openings that allow Blue Jays to pull out the peanuts, providing both food and entertainment for the birds.

4. Suet Feeders

Wire or cage-style suet feeders are great for offering suet cakes to Blue Jays. Hang these feeders in areas where Blue Jays can easily access them, but ensure they are sturdy enough to support their weight.

Creating a Blue Jay-Friendly Backyard

Feeding Blue Jays is just one part of attracting them to your yard. Creating a Blue Jay-friendly habitat will encourage these birds to visit more frequently and stay longer.

1. Provide Water Sources

Blue Jays need water for both drinking and bathing. A birdbath or shallow water dish will attract Blue Jays to your yard. Ensure the water is clean and refreshed regularly.

2. Plant Native Trees and Shrubs

Blue Jays rely on trees and shrubs for food, shelter, and nesting sites. Planting native species like oaks, pines, and maples will provide natural food sources, such as acorns and insects. Berry-producing shrubs like elderberry and serviceberry are also great for attracting Blue Jays.

3. Offer Nesting Materials

During breeding season, Blue Jays look for materials to build their nests. You can help by leaving out twigs, grasses, and pine needles. Some people also offer nesting boxes, though Blue Jays typically prefer natural tree cavities.

4. Create a Safe Environment

Blue Jays are bold birds, but they still need a safe environment free from predators like cats and large birds of prey. Place feeders and birdbaths in areas where they can easily spot threats and escape if needed.

Seasonal Feeding Tips

As the seasons change, so do the feeding needs of Blue Jays. Here are some tips for feeding Blue Jays throughout the year.

Spring

In spring, Blue Jays are busy preparing for the breeding season and will appreciate high-protein foods like insects and mealworms. You can also offer sunflower seeds, suet, and fruits to support their nutritional needs during this time.

Summer

During the summer months, Blue Jays continue to need protein to raise their young. In addition to insects and mealworms, offering nuts, berries, and fruits will keep them well-fed.

Fall

Fall is a crucial time for Blue Jays as they prepare for winter. They begin to store food, particularly acorns and nuts, for the colder months. Offering peanuts, acorns, and sunflower seeds can help them stock up.

Winter

In winter, Blue Jays need high-energy foods to stay warm. Suet, peanuts, sunflower seeds, and cracked corn are excellent options. Make sure feeders are kept clean and filled, as natural food sources may be scarce.

Interesting Blue Jay Behavior Related to Feeding

• Food Caching — One of the most fascinating behaviors of Blue Jays is their food caching habit. They will store food, such as acorns, by burying it in the ground or hiding it in tree crevices. This not only ensures they have food during lean times but also plays a vital role in forest regeneration, as many of the seeds they bury end up sprouting into trees.
• Mimicry — Blue Jays are excellent mimics and are known to imitate the calls of hawks. They may do this to scare other birds away from food sources or to warn fellow Blue Jays of nearby predators.
• Social Behavior — Blue Jays are social birds and are often seen in small family groups. They communicate with each other through a wide range of vocalizations and body language, often working together to fend off predators or gather food.

Conclusion

Blue Jays are not only beautiful but also intelligent and resourceful birds. By understanding what they eat and how to feed them, you can attract these vibrant birds to your backyard, creating a lively and dynamic bird-watching experience. From offering a variety of nuts, seeds, fruits, and insects to providing the right type of feeders and creating a Blue Jay-friendly habitat, there are many ways to make your yard a haven for these fascinating birds.
