Which plant is known to provide berries that are a food source for birds during winter?

Holly is well-known for its bright red berries, which serve as an important food source for many bird species during winter months. The berries provide essential nutrients and energy when other food sources may be scarce. Birds such as thrushes and blackbirds are particularly fond of holly berries, and their presence can help support local bird populations through harsh winters.

In contrast, while brambles produce berries that are favored by birds in other seasons, their primary fruiting occurs in summer and early autumn. Thornbushes may provide shelter but are not particularly known for their berries. Pine trees, on the other hand, produce cones and do offer seeds that some birds eat, but they do not provide the accessible, fleshy berries that holly does, making holly the standout choice for winter bird food.
