      Sunflower Seeds FAQs

      What is the difference between sunflower seeds and sunflower hearts? 

      Sunflower hearts are sunflower seeds that have the husk and outer shell mechanically removed, which means sunflower hearts cause less mess in your garden when birds come to feed. 

      Can you put sunflower seeds in a bird feeder? 

      Sunflower seeds attract a wide variety of birds, which makes them a great choice for most outdoor bird feeders. If you’re using sunflower hearts for birds, know that the chips quickly spoil and can harbour bacteria, so fill your bird feeder with no more than can be eaten in a day or two.

      Is too much sunflower seed bad for birds? 

      Sunflower seeds are an excellent food source, but eating too much can be bad for birds. The high-fat content in sunflower seeds can cause obesity in birds, so it’s best to feed in moderation with a healthy mixture of other seeds like flaked maize and peanut granules.
