Do birds eat snowberry berries?

Answered by James Kissner

Birds do eat snowberry berries. Snowberry (Symphoricarpos spp.) is a shrub that produces small white fruits in the fall, typically in September or October. These berries are quite distinctive, with their bright white coloration standing out against the green foliage. The berries are relatively small, typically around 0.5 to 0.8 centimeters in diameter.

While snowberry berries are toxic to some animals, including fish, they are enjoyed by many species of birds. Birds play a crucial role in the dispersal of snowberry seeds, as they eat the berries and then spread the seeds through their droppings. This helps to ensure the continued growth and spread of snowberry shrubs.

Various bird species have been observed feeding on snowberry berries. Grouse, including ruffed grouse and sharp-tailed grouse, are known to consume these fruits. The berries also attract certain species of thrushes, such as the hermit thrush and Swainson’s thrush. Additionally, grosbeaks, including the evening grosbeak and the pine grosbeak, have been observed feeding on snowberry berries.

Birds are attracted to snowberry berries for their nutritional value and energy content. The berries provide a good source of carbohydrates and fats, which are essential for birds, especially during the colder months when food sources may be scarce. Snowberry shrubs, with their persistent fruits that last through the winter, can serve as an important food source for birds during this time.

It is important to note that while birds can safely consume snowberry berries, some other animals may experience adverse effects from ingesting them. The berries contain compounds called saponins, which can be toxic to certain species. Fish, in particular, are highly sensitive to these compounds and can be affected if they consume snowberry berries or if the saponins leach into water bodies where the shrubs are located.

Snowberry berries are indeed consumed by birds. Despite their toxicity to some animals, birds are attracted to the nutritious berries and play a vital role in dispersing the shrub’s seeds. The persistent white fruits of snowberry shrubs provide a valuable food source for birds during the winter months when other food may be scarce.
