In short: Put out suet mainly in late fall through early spring, when temperatures drop below about 40°F and natural food becomes scarce. Birds rely on the high-energy fat during cold weather; summer feeding is rarely needed and can spoil.
Part of our guide on feeders to keep pigeons out
Know exactly when to put out suet for birds to maximize feeding success through the seasons and avoid common mistakes.
| Ideal temp | below 40°F |
|---|---|
| Suet seasons | fall to spring |
| Summer use | generally not needed |
| Feeder types | cage or log |
| Bird energy | high from fat |
The short version
- Suet feeding works best below 40°F when food is scarce.
- Avoid suet in hot weather to prevent spoilage.
- Hang suet feeders securely to keep birds safe.
- Use suet mainly from late fall to early spring.
- Birds eat suet for energy and survival in cold weather.
When to put out suet for birds
Start putting out suet in late fall when daily highs drop below about 40°F. Birds need extra fat to survive colder temperatures and decreasing natural food.
Continue suet feeding through winter and into early spring while conditions remain cold or food is scarce. These months present the highest demand for calorie-dense supplements.
Stop offering suet once temperatures regularly rise above 50°F and natural foods like insects and berries return. Warm weather risks suet melting and spoiling quickly.
You can monitor local temperatures and bird activity to time feeding. If skies are gray and natural food is limited, adding suet helps birds maintain energy. If that sounds like your situation, read up on starting winter bird feeding next.
Local climate affects when to put out suet. In milder zones, start feeding later in fall and stop sooner in spring. In harsh northern areas, feeding may be necessary from October through April.
Watch bird behavior for signs to start feeding. If you see woodpeckers and chickadees frequently at your feeders but seem restless or thin, it’s time for suet. Their increased visits mean natural food is limited.
Check the suet regularly during thaws or warm spells. Softening or melting suet signals warm weather and the need to pause feeding to avoid spoilage and attracting pests. Returning cold snaps require putting suet back out quickly. We go through building a bird feeder that squirrels can't access step by step elsewhere on the site.

Why do birds eat suet
Birds consume suet because it provides a dense source of fat and calories. Fat offers much more energy per gram than seeds or insects.
In cold weather, birds burn calories rapidly to keep warm. Suet helps them meet this demand efficiently.
Some insect-eating birds rely on suet when insects become scarce in winter. It helps to understand how to fix birds not eating suet before going further.
High-energy fat also aids migration and molting when birds require extra nutrition.
Birds can gain up to 50% of their daily energy from suet during cold spells. This makes it crucial for species like woodpeckers and nuthatches that rely heavily on fat for survival.
Suet also provides essential nutrients like vitamins A and E, which help birds maintain strong feathers and immune systems. These nutrients are harder to get from seeds alone. There is more on bees attracted to bird seed in a separate guide.
During migration, birds increase fat stores to fuel long flights. Suet feeding nearby helps some species build these reserves faster, increasing their chances of successful travel.
How to put out suet for birds
Use specialized suet feeders made from metal cages or plastic containers that hold and protect the suet block while allowing birds to cling and peck.
Hang feeders in sheltered, visible spots 5 to 6 feet above ground to reduce predator risks and attract birds. It helps to understand feeding fledgling parrots before going further.
Replace suet blocks every 4 to 7 days, or sooner if they melt or get dirty, to keep the food fresh and safe.
Clean feeders regularly with hot water to prevent disease spread among visiting birds.
Place suet feeders away from feeders for seeds to reduce crowding and fighting. Some birds prefer suet feeders and avoid seed feeders, so spacing helps all species feed comfortably.
In hot weather, use suet feeders with built-in cooling features or place them in shaded spots to slow melting. This can extend the feeding season slightly.
Observe which birds visit your feeders and adjust suet types accordingly. Some birds prefer plain suet, while others like suet mixed with peanuts or dried insects.
- Choose a suet feeder suitable for your backyard bird species.
- Hang the feeder on a sturdy branch or hook in a well-visible place.
- Check the suet daily for melting or spoilage, especially during warm spells.
- Replace suet blocks promptly and clean feeders monthly.
Do birds need suet in summer
Birds usually do not need suet in summer. High temperatures cause suet to melt and spoil rapidly, which deters birds and attracts unwanted pests.
Natural foods like insects and fruits become abundant in warm months, reducing the need for supplemental fat.
Some bird owners avoid suet during hot months to prevent health risks and mess.
If you want to feed birds in summer, offer seeds, nectar, or fresh fruits instead.
Feeding suet to birds in winter
Winter is the prime time to feed suet because birds expend more energy staying warm and food is scarce.
Suet blocks remain solid longer in cold weather, allowing birds to feed easily without waste.
Providing suet boosts survival chances for insectivorous birds that can't find enough food under frozen conditions.
Keep suet feeders stocked regularly through winter to maintain a reliable energy source.
How to hang suet for birds
Hang suet feeders 5 to 6 feet above ground to keep birds safe from cats and other predators.
Choose spots near trees or shrubs to provide perches and cover but avoid placing feeders too close to windows to prevent collisions.
Use sturdy hooks or branches to support the feeder's weight and resist wind.
Rotate feeder locations occasionally to minimize buildup of bird droppings and disease risk.
- Height: 5-6 feet from ground for safety
- Location: near cover but away from windows
- Support: strong hook or branch
- Rotation: move feeder every few weeks
Questions people still ask
Can I put out suet all year round?
Suet is best from late fall through early spring when temperatures are below 40°F. Year-round feeding risks spoilage and pests in warm weather.
What types of birds eat suet?
Woodpeckers, nuthatches, chickadees, wrens, and some sparrows commonly eat suet, especially in cold months.
How often should I replace suet?
Replace suet every 4 to 7 days or sooner if it melts or gets dirty. Frequent replacement keeps birds healthy.
Is homemade suet safe for birds?
Homemade suet can be safe if made with bird-friendly ingredients. Avoid salt, seasonings, or rancid fats.
Why do some birds avoid suet feeders?
Birds may avoid suet if it’s too warm and soft, feeder placement is poor, or if local species don’t typically eat fat.
