Find the Right Birdfeeders For Your Backyard

Bird Feeders

The type of bird feeder you use will determine which birds come to your yard to eat. Do you want hummingbirds, woodpeckers, orioles, chickadees, cardinals, goldfinches or doves?

Some birds want to eat on the ground while others prefer eating while hanging upside down! Did you know that the size of the holes in a feeder and the length of the perches can keep away birds like Starlings while attracting smaller birds?

Maybe you would like to attract ALL the birds to your yard. In this case you will need a number of different feeder types!

Hummingbird Feeder Hummingbird feeders hold liquid and have very narrow openings. Make your own hummingbird nectar by mixing 4 parts water and 1 part sugar.
Thistle Feeder Thistle feeders hold Niger ("Thistle") seeds and have narrow openings for Goldfinches.
Squirrel-proof Feeders Squirrel-Proof Feeders are designed to keep squirrels away from the seed. Some work with batteries and involve a moving perch.
Seed/Tube Feeders Seed/Tube feeders are cylindrical tubes with openings up and down the tube -- perfect for Chickadees and Cardinals. Shorten the perches to keep larger birds away.
Suet Feeder Suet feeders are wire or mesh baskets that hold suet or pre-packaged suet cakes. Woodpeckers love these!
Dome Feeder Dome feeders are feeders that typically are covered by a large plastic dome to keep out the rain and snow. Seed spills out at the bottom. Also known as Bowl feeders

 

Window Feeder

 

Window feeders attach to the outside of your window. Clear plastic lets you see the birds as they eat a few inches from you.

 

Hopper Feeder

 

 

Hopper feeders are bins that hold seeds that spill out of the bottom as the birds eat. Many birds will come to these -- including larger birds like Blue Jays, Grackles and Starlings.

You can also sprinkle seeds directly on the ground -- but this attracts other critters as well. Specialized feeders include pine cones (great for lathering with peanut butter), and sharpened sticks to hold orange halves for Orioles.

Keep your feeders clean!
Look closely at the feeder. Would you eat or drink from it yourself? It is extremely important that you clean your feeders at least once every two weeks. Use a mixture of 2 gallons of water and 1/4 cup of bleach. Let the feeders air-dry before rehanging them. When you refill feeders, shake out damp seeds that may become moldy. Remove hulls from the feeder. Change the solution in hummingbird feeders at least every three days during warm weather.
