Landscaping for Bluebirds and other Birds

Bluebirds rarely eat birdseed (although they will occasionally take shelled sunflower chips). 68% of their diet is made up of insects such as grasshoppers, crickets, beetles, spiders, and caterpillars. They enjoy mealworms. They may eat suet, especially during winter months. They also like the fruit of plants such as flowering      dogwood, eastern red cedar, holly, elderberry, Virginia creeper and pokeweed. Staghorn sumac, although not a preferred food, is an essential winter survival food 

along with winterberry. 

I plan on listing the various plants which not only bluebirds but all birds rely on for either summer food for their young or for winter survival.
