The Smithsonian Zoo has a great list:

We get Birds and Beans coffee (which is good) and Songbird decaf from 
Thanksgiving Coffee (which is delicious).
The challenge is to get stores to carry some of these wonderful brews. 
When I asked at one health food store, I was told that "all our coffees 
are bird-friendly; they come from South American, and South American has 
tons of birds!" I finally met with the person in charge of ordering, but 
she said they couldn't stock one of the bird-friendly coffees because 
they had to buy through their regular distributor.
