Sunflower bird seed is by far the most popular bird seed that attracts a large variety of wild birds. There are quite a few types and styles of
Bird Feeders for sunflower seeds and most do a good job.
The
Sunflower Seed Bird Feeder shown here is a wire mesh style that Cardianls will come to and which allows many more birds being able to feed at the same time. It has a small tray to accommodate the perching birds like Cardinals. Clinging birds like the Chickadee, Titmouse, Nuthatch and Woodpeckers like to cling to the wire mesh to feed. It can also discourage larger undesirable birds like Grackles and Mourning Doves.
Goldfinch Thistle seed bird feeders
are the second most popular type of bird feeder. Thistle seed is tiny seeds that Goldfinches and others love. A good example of a thistle feeder is the yellow accented wire mesh feeder designed just for the thistle. This Finch Tube Bird Feeder has internal dividers to maintain seed in upper levels for longer use by many birds. Its tray catches fallen seed so the birds can still find and use it.
Peanut bird feeders can be added as an extra type of feeder to attract more unusual types of birds. The
Woodpecker Peanut Bird Feeder holds the peanuts in wire openings that are just right to allow birds to peck their treat out. This gives the opportunity to see these birds for a longer time. Red Belly Woodpeckers, Downy Woodpeckers, Hairy Woodpeckers, Nuthatches, etc. all frequent this type of feeder. The spiral arm gives them an extra perch that they like to go around on to find their choice peanut.
These are just a few examples of all the different styles available, more
Bird Feeders can be seen here.
Squirrel Baffles can be added to these bird feeders to have
Squirrel Proof Bird Feeders.
