I really don't like birds. They make a mess in the garden, but they especially like to steal newly planted seeds and new seedlings as they are coming out of the ground. There are several products that you can buy to keep birds out, but this is the least expensive one and it works perfectly.
PIN-WHEELS!!!
The aluminum ones work the best because they reflect more, but the birds just don't bother the garden when I have these place in various locations in the garden.
