Answer: That's a great idea -- fruiting and flowering trees are a real boon to our flying friends (oh, that's a lot of alliteration!). If you can't find black cherry (Prunus serotina) at area nurseries, here are some mail-order sources:

Something to keep in mind -- mature black cherry trees can reach 75-80 feet in height, so make sure they'll fit into your landscape plans for the long run. If not, there are plenty of other native cherries that are smaller, even shrub-sized, such as Purnus besseyi (Western Sand Cherry) and P. pumila (Sand Cherry).
Are you aware that there's a program sponsored by the National Wildlife Federation that supports gardeners and landscapers who garden for wildlife? You can find out more about their program and materials via their Web site:
