Why do birds love sunflower hearts?

Sunflower hearts are a bird’s equivalent of a high-energy snack with the packaging already removed. Here’s why they are so nutritious for our feathered friends. . .

They’re energy-rich

Sunflower hearts contain plenty of health fats, which are extremely valuable, especially in colder weather when birds need more calories to maintain their bodyweight and temperature.

They’re full of protein

Protein is an essential part of the avian diet, as it is used for muscle maintenance, feather growth and during the breeding season to produce and raise strong, healthy chicks.

They’re easy to eat

While sunflower seeds are a bit more complicated to eat, with their tough outer husk, sunflower seeds already have this removed. Your birds can simply pick up a heart and swallow it, without wasting any additional energy.

They’re small and versatile

They are the perfect size for many garden birds to handle with ease, particularly tits, finches, sparrows, robins and dunnocks.

They’re highly digestible

The edible kernel has little indigestible material, so birds get a high nutritional return for each mouthful.

They’re free from waste

Sunflower hearts are brilliant for gardeners, as there’s no mess, with discarded husks left beneath the feeder.

They’re an efficient food package

They are perfect for grabbing and flying quickly away, which reduces the time birds remain exposed to predators around a feeder.
