How do you keep blackbirds off your bird feeder?
Considering this, how do you keep big birds out of your bird feeder?
Try enclosing the feeders with large-mesh hardware cloth or chicken wire with openings big enough to allow smaller birds to pass through (a 2-inch opening should do). This will exclude the large bully birds. You can also purchase caged-in tube or tray feeders at your local bird, hardware or garden store.
Additionally, how do you keep Magpies away from bird feeders?
Netting comes in many different sizes and can be cut to fit your plants and cages. Cover vegetables and fruit plants with it. Magpies will be able to see the fruit, but won't be able to pick at it very much. This will help to keep them away as they will eventually have to find another source of food.
The blackbirds regularly move in large flocks when the weather gets colder in the late fall, sometimes taking flight in groups as large as 5,000 birds. With their seasonal precision, the birds almost serve as a natural calendar for observers as they have come to expect massive movement when the temperatures drop.
