Catbird on a perch at my feeder.
My two birdwatchers,Betty and Madelaine.
Predators should also be considered. You wouldn't want to serve up your new feathered friends within easy reach of your neighbors cat or out in the open where they might fall prey to a hawk.It is a good idea to place your feeder near some greenery,such as bushes or a low hanging tree. This will give your birds a place of refuge and not leave them too open and approachable by predators.
Another possible predator.
Predators are out there and will occasionally visit your backyard. Over the years I've had a bluebird and a woodpecker taken right in front of me and my son by a red-tailed hawk. The bluebird was taken from behind while perched on her nesting box and the woodpecker was on my kitchen window screen.You can't stop the circle of life from happening,but you can control it some with proper placement.
Good luck with your bird feeder and keep these things in mind when you first put one up. You'll be enjoying beautiful new scenery and songs provided by nature, right in your own backyard.
