Sunflower Seeds vs Safflower Seeds
Feeding wild birds is a rewarding hobby that brings color and song to your backyard. One of the most common questions among bird enthusiasts is: what type of seed should you offer to attract the widest variety of feathered friends? Two of the most popular options are sunflower seeds and safflower seeds. In this post, we’ll compare these two seeds, discuss their benefits and drawbacks, and help you decide which is best for your bird feeder.

What Are Sunflower Seeds?
Sunflower seeds are perhaps the most popular birdseed, loved by a wide range of birds. They come in two main types: black oil sunflower seeds and striped sunflower seeds. Black oil sunflower seeds have thin shells and a high fat content, making them easy for birds to eat and a great source of energy, especially in winter. Striped sunflower seeds have thicker shells and are a bit harder for small birds to crack.
Birds That Love Sunflower Seeds
- Cardinals
- Chickadees
- Finches
- Nuthatches
- Titmice
- Woodpeckers
Sunflower seeds are also enjoyed by less-welcome visitors like squirrels, grackles, and starlings.
What Are Safflower Seeds?
Safflower seeds are white, oval seeds with a hard shell. They are less well-known than sunflower seeds but are gaining popularity among backyard birders. Safflower seeds are slightly lower in fat than sunflower seeds but are still nutritious and provide protein and fiber.
Birds That Love Safflower Seeds
- Cardinals
- Grosbeaks
- House Finches
- Mourning Doves
- Chickadees
One of the main benefits of safflower seeds is that they are less attractive to squirrels, grackles, and blackbirds, which can help keep your feeder focused on songbirds.

Nutritional Comparison
Seed Type | Fat Content | Protein | Fiber | Birds Attracted |
---|---|---|---|---|
Sunflower Seeds | High | Good | Good | Wide variety, including pests |
Safflower Seeds | Moderate | Good | Good | Selective, mainly songbirds |
Sunflower seeds provide more energy due to their higher fat content, making them especially valuable during cold months. Safflower seeds offer similar protein and fiber but are a little less calorie-dense.
Pros and Cons
Sunflower Seeds
Pros:
- Attract the widest variety of birds
- High in fat and energy
- Easy for most birds to eat (especially black oil type)
Cons:
- Attract squirrels, grackles, and starlings
- Can be messy due to shells
Safflower Seeds
Pros:
- Attract cardinals and other songbirds
- Less attractive to squirrels and nuisance birds
- Less mess at feeders
Cons:
- Harder shell may deter some small birds
- Slightly less energy content
Which Should You Choose?
If your goal is to attract as many bird species as possible, sunflower seeds are the best choice. They are versatile, nutritious, and loved by most backyard birds. However, if you want to discourage squirrels and larger, aggressive birds, safflower seeds are an excellent alternative. They are especially good for attracting cardinals and doves while keeping your feeder quieter and more selective.
For the best of both worlds, consider offering both types in separate feeders. This way, you can observe which birds visit each feeder and adjust your offerings based on your preferences.
Tips for Feeding Birds
- Place feeders in a safe, quiet area away from predators.
- Clean feeders regularly to prevent disease.
- Provide fresh water for drinking and bathing.
- Offer a variety of seeds to attract different species.
Conclusion
Both sunflower seeds and safflower seeds are excellent choices for backyard bird feeding. Sunflower seeds will bring the widest variety of birds, but safflower seeds can help you focus on cardinals and deter unwanted guests. Try both and see which works best for your backyard!
