Can Birds Eat Grapes? (Which Species + How To Feed)

But are grapes safe for birds to eat? Keep reading as we investigate which bird species are particularly partial to grapes, and if any special preparation is needed before grapes can be fed to birds.

Many bird species eat grapes, both in the wild and in captivity. Grapes offer a source of hydration and nutrition, as well as a supply of vitamins and antioxidants vital for good health. Grapes do not need to be peeled or chopped, and for some birds, even ripeness – or lack of it – is not an issue.

While vines can attract certain bird species in summer when grapes begin to ripen, other birds prefer to forage for fruit once it has become over-ripe and fallen to the ground.

Birds will also take grapes left in feeders and at backyard bird tables. Supermarket-bought grapes are also fine for birds to feast on, but it’s recommended to give them a thorough wash to ensure there is no contamination from pesticides.

Read on to find out which birds are especially fond of grapes, and what nutritional benefits grapes bring to a bird’s diet.

How to feed grapes to birds

For wild birds, grapes can be left on bird tables, feeding stations, in bird feeders and even on the ground. There’s no single, correct way to feed grapes to a bird. If grapes are chopped or halved, then they are likely to rot quicker, so need to be checked and discarded if any signs of decay are spotted to avoid the risk of bacterial infections.

Parrots, lovebirds, and other birds kept in captivity can be offered uncut grapes, and may especially enjoy the challenge of tackling the whole fruit as a wild bird might.

Chopped grapes, mixed in with grain, seed or other specialist bird food as an occasional treat, will prevent pet birds from becoming overly addicted to the exceptionally sweet taste of grapes.
