Providing high calorie and high fat foods can be important to the birds.
The birds visiting winter feeders may be arriving in flocks or may come to the feeders as individuals, so you will need to provide different options for the birds.

Position of feeders

Feeders should be located out of the wind. The east or southeast side of a house or near a row of trees is ideal. It is best to have a perching spot such as a bush or tree for the birds to use to survey the feeding area and provide sufficient cover for safe refuge from predators and shelter from the wind and weather. The feeders should be positioned near cover but in the open to allow birds to watch for danger.
For ground feeding, an area near cover with a clear view of the surroundings is desirable.

 

Ground feeders

Placing seed in a ground feeder entices birds such as sparrows, juncos, Mourning Doves, quail, pheasants, towhees and Brown Thrashers.
Even the Red-bellied Woodpecker, which is thought of as a tree dweller, does some foraging on the ground.

 

 

 

High feeders

Platform and  hopper feeders are especially good for attracting cardinals, wrens, chickadees, titmice, jays, and grosbeaks.

 

 

 

 

 

 

 

 

 

 

 

 

Hanging feeders, because they blow in the wind, are generally used by those species that are able to hang on while feeding such as chickadees, titmice, nuthatches and finches.
