There are a few things to keep in mind when hanging a bird feeder from a tree: First, make sure the feeder is positioned well below the canopy of the tree; this will help to prevent birds from becoming tangled in the feeder. Second, make sure the feeder is situated so that it doesn't block too much of the natural light that reaches the trees' branches. Finally, be sure to install proper hardware (e.g. hooks and suction cups) to ensure that your bird feeder stays firmly in place.
