Keep birds out of your garden with the use of scarecrows. From a distance, birds will not come anywhere near a scarecrow. They will think that a scarecrow is an actual person who is willing to attack them. As you may already know, animals get scared easily by humans. At night, place lights around this hay-filled doll for a spookier effect.
Some farmers like to use fake owls, hawks or other stuffed representations of predators that stalk birds. The birds will not dare get close to a garden that is being watched by a bigger, more intimidating animal. However, some animals are clever enough to figure out that the predator is fake. To make the setting more realistic, move the stuffed animals around as if they have moved positions.
Also, covering the garden is another way to keep the birds out. Use a net or sheet to cover the plants that are attracting winged creatures. It is only a temporary solution, though, because the net comes off eventually.
Plants need sunlight to survive at least, so you want to use the net occasionally. If you do not have time to build a scarecrow, throw on a net. It is not pretty to look at, but it keeps the animals out for the time being.
