What is Suet and Why Do Birds Love It?

Definition of suet

Suet is a type of animal fat that is commonly used as a food source for birds. It is typically obtained from the fat found in beef or sheep, although other animal fats can also be used. Suet is solid at room temperature and has a high melting point, which makes it ideal for use in bird feeders.

High-fat energy source

Birds love suet because it is a high-fat energy source that provides them with the calories they need to fuel their activities. The fat content in suet helps birds maintain their body temperature, especially during colder months.

It is also a great source of energy for birds during migration or breeding seasons when their energy requirements are higher.

Suet is particularly beneficial for birds that have high metabolic rates, such as woodpeckers, nuthatches, and chickadees. These birds have a higher need for energy and will readily consume suet to meet their dietary needs.

Not only does suet provide birds with the energy they need, but it also contains essential nutrients such as protein and vitamins. This makes it a nutritious food source for birds, helping them stay healthy and thrive in their natural habitats.

Additionally, suet is an easily accessible food source for birds. It can be conveniently offered in bird feeders or hung in mesh bags from trees. Birds are attracted to the scent and taste of suet, making it a popular choice among birdwatchers and backyard bird enthusiasts.

However, it is important to note that while suet can be beneficial for birds, it should be offered in moderation. Excessive consumption of suet can lead to health issues in birds, such as obesity or nutritional imbalances.

It is best to provide suet as part of a varied and balanced diet that includes other bird-friendly foods like seeds, fruits, and insects.

Nutritional Value of Suet for Birds

High in calories

Suet is a highly nutritious food source for birds, especially during the winter months when their energy requirements are higher. It is known for its high calorie content, which helps birds maintain their energy levels and stay warm in cold weather.

A single serving of suet can provide a substantial amount of calories, giving birds the fuel they need to survive and thrive.

Provides some vitamins

While suet is primarily a source of energy for birds, it also contains some essential vitamins that contribute to their overall health. Vitamins such as vitamin A, vitamin E, and vitamin D can be found in suet, providing birds with important nutrients that support their immune system, feather health, and overall well-being.

These vitamins play a crucial role in maintaining the health and vitality of birds.

It’s important to note that while suet does offer some nutritional benefits, it should not be the sole source of food for birds. A varied diet is crucial for their overall health and well-being. In addition to suet, birds should have access to a diverse range of foods such as seeds, nuts, fruits, and insects to ensure they receive a balanced and nutritious diet.

For more information on bird nutrition and feeding habits, you can visit the Audubon Society website. They provide valuable insights and resources on how to attract and feed birds in a way that promotes their health and happiness.

Potential Downsides of Suet for Bird Health

High cholesterol

While suet can be a valuable source of energy for birds, it is important to consider the potential downsides. One concern is the high cholesterol content of suet. Just like in humans, high cholesterol levels can lead to health issues in birds.

It is important to remember that birds have different nutritional needs than humans, and an excessive intake of cholesterol may not be beneficial for their overall health.

According to a study conducted by the Audubon Society, a high cholesterol diet can lead to atherosclerosis in birds, which is the build-up of fatty deposits in their arteries. This can eventually lead to heart problems and reduce their lifespan.

Therefore, it is recommended to offer suet as an occasional treat rather than a daily staple.

Risk of spoiled suet

Another potential downside of suet is the risk of spoilage. Suet is a fatty substance that can go rancid if not stored properly. When suet becomes spoiled, it may contain harmful bacteria or fungi that can cause digestive issues or even illness in birds.

To prevent this, it is essential to follow proper storage guidelines. Store suet in a cool and dry place, preferably in an airtight container. Check the suet regularly for any signs of spoilage, such as a foul odor or mold growth.

If you notice any of these signs, it is best to discard the suet and replace it with fresh, uncontaminated suet.

Choking hazard

Suet, especially if offered in large chunks or without any modifications, can pose a choking hazard to birds. Birds may try to swallow large pieces of suet, which can get lodged in their throat or digestive tract, leading to choking or blockage.

To mitigate this risk, it is recommended to offer suet in smaller, easily consumable portions. Suet cages or feeders with small openings can help prevent birds from taking large chunks at once. Alternatively, you can consider mixing suet with other bird-friendly ingredients, such as seeds or dried fruits, to create a more manageable texture.

Alternatives to Suet for Backyard Birds

Seed cakes

Seed cakes are an excellent alternative to suet for feeding backyard birds. These cakes are made from a mixture of bird seeds, nuts, and other ingredients that birds love. They are typically shaped into blocks or cakes and can be easily hung from a tree or placed in a feeding tray.

Seed cakes provide birds with a high-energy food source and are a great option for attracting a variety of bird species to your backyard.

Peanut butter mixes

Peanut butter mixes are another popular alternative to suet for backyard birds. These mixes usually consist of peanut butter, cornmeal, and bird seeds. Birds are attracted to the high protein content in peanut butter, making it a nutritious and tasty treat for them.

To offer peanut butter mixes to birds, you can spread them on pinecones, tree bark, or use specially designed feeders. It’s important to use unsalted and natural peanut butter without any added sugars or artificial sweeteners.

Lard bird feeders

Lard bird feeders are a traditional option that has been used for many years to attract birds to the backyard. Lard, or rendered animal fat, is mixed with various bird seeds and grains to create a high-fat food source for birds.

You can easily make lard bird feeders by mixing melted lard with a seed mixture and pouring it into molds or containers. Once the mixture solidifies, you can hang the feeders outside for birds to enjoy.

It’s important to note that lard bird feeders may melt in warm weather, so they are best suited for cooler climates.

When considering alternatives to suet for birds, it’s essential to choose options that are safe and nutritious for them. Always use high-quality ingredients and avoid additives like salt or sugar. By providing a variety of food sources, you can attract a diverse range of bird species to your backyard and create a welcoming environment for these beautiful creatures.

Tips for Safely Offering Suet to Birds

Pick quality suet

When offering suet to birds, it is important to choose high-quality suet. Look for suet that is specifically made for birds and does not contain any harmful additives or preservatives. Opt for suet that is made from natural ingredients and does not contain any artificial colors or flavors.

This will ensure that the birds are getting a healthy and nutritious meal.

According to experts at the Audubon Society, suet cakes with a higher fat content are preferable, as they provide more energy for the birds. Additionally, suet that contains a mix of seeds, nuts, and fruits can attract a wider variety of bird species to your backyard.

Avoid warm weather

Suet has a tendency to melt in warm temperatures, which can become messy and unappetizing for birds. It is best to offer suet during cooler months when the weather is below 70°F (21°C). If you live in a region with consistently warm weather, consider offering suet in the early morning or late evening when temperatures are cooler.

According to the Cornell Lab of Ornithology, it is crucial to monitor suet feeders closely during hot weather to prevent the suet from spoiling. If you notice the suet melting or becoming rancid, it is advisable to remove it and replace it with fresh suet.

Clean feeders regularly

Regular cleaning of suet feeders is essential for the health of the birds. Dirty feeders can harbor bacteria and mold, which can be harmful to the birds. Clean the suet feeder at least once a week with warm soapy water and rinse it thoroughly to remove any residue.

This will help prevent the spread of diseases and ensure that the birds have a safe feeding environment.

Experts at the National Wildlife Federation recommend wearing gloves while cleaning feeders and avoiding the use of harsh chemicals or bleach. It is also important to dry the feeder completely before refilling it with fresh suet.

Use cages or meshes

Using cages or meshes to offer suet can prevent larger birds or squirrels from monopolizing the feeder. These cages or meshes allow smaller birds to access the suet while deterring larger, more aggressive birds.

They also provide a safe feeding space for birds, reducing the risk of injury or predation.

According to the Royal Society for the Protection of Birds, suet cages or feeders should have small enough openings to prevent larger birds from entering. Consider placing the suet feeder in a location that is easily accessible for smaller birds but more challenging for larger ones.

By following these tips, you can offer suet to birds safely and provide them with a nutritious food source. Remember to observe the birds’ behavior and adjust your feeding methods accordingly to ensure their well-being.


Suet can provide an appealing high-energy food source for backyard birds during winter, but it may pose some health risks if fed in large quantities year-round. Using alternative fats like seed cakes or lard, following proper suet feeding tips, and moderating intake can allow birds to safely enjoy suet’s benefits during cold weather.

By understanding suet’s pros and cons for birds, we can make informed decisions about including it as part of a varied bird-feeding diet that supports avian health.
