Eye Balloons

Balloons with strange, large eyes painted on them are tied to tree branches or fences to keep the birds away. These look strange and look like the eye of a predator to the birds. This method is similar in effect to using a scarecrow.
Fruit Cages

Fruit cages are a more permanent solution. However, it is particularly vulnerable to crops like raspberries, blueberries, and cherries in fruit cages. They are very effective but can be expensive and high maintenance.
Bird Netting

You can use a bird net to cover the entire fruit tree to keep the birds out. Be sure to use fine bird netting, preventing birds from getting inside the net and becoming stuck inside. Cover the tree with a frame and wrap the net over the frame, making sure there are no gaps for birds to get in.
Predator Decoy

Predator decoy is one of the best ways to protect your fruit trees from birds. It is very effective against birds scared of predatory owls or hawks, while it is a little bit more expensive than other options.
Final Words
Although some birds can be pests, they are also hardworking garden allies, eating away from disturbing pests like snails and harmful insects. Unfortunately, no matter where you garden, a local pest bird is eyeing up your homegrown fruits. So, use the above methods to keep them off your trees, so they don’t eat up your fruits before they are ripe.
