I have a yellow birch tree in my front yard and I find that it attracts a wide variety of birds -- they seem to feed off it....everyone from the downies/ hairys and yellow bellies...wrens...chickadees, juncos...warblers and flycatchers....I've had indigo buntings and scarlet tanagers feeding from it...ruffed grouse...I've had coopers / sharp shinned hawks using it for hunting grounds....
It's the greatest tree ever invented...just wished they lived longer.
another good one is the crab apple tree....
Nice thread ! I'm interested in following this one.
