Bird Feeders

Hi! I am planning to install a bird feeder in my garden space because I would love to hear the sound of chirping and twittering birds early in the morning. Bird feeder should be such, that it should add beauty to my garden space as well as serve to the birds also. I'm looking for some suggestions regarding the material of the bird feeders, designs available and it's placement in my garden space which is of prime importance. Also tell me the pros and cons of the bird feeder installled in a garden space. Please suggest me whether I should go for a hanging bird feeder or one with a stand. Please reply on this soon. Thanks!
