Can you post a photo of the leaves and plant so we can be sure that the tree actually is a birch rather than a seedling from another tree that just happened to grow in that area? There are some trees that have birch-like leaves.

I have not seen birch leaves turn other than yellow with perhaps some slight orange tints. I have paper birch/Betula papyrifera, black birch/B. lenta, yellow birch/B. alleghaniensis, and gray birch/B. populifolia, and regardless of age or location, I have not seen red tones to the leaves, either on my own property or as I am out and about. IME it isn't unusual for young, small trees to hang on to leaves a bit longer than more mature plants.

The tree now.

Callery pear.

Thanks for the photo. I don't know where you are but as hairmetal mentioned this plant is invasive in much of the eastern half of the US. Birds eat the fruit and deposit seeds where ever they fly, and the pears outcompete native vegetation. They are thorny and have stinky flowers and tend to self-destruct during snow or ice storms about the time they start getting reasonable size, so this is one I would advise removing to your trash.

Thanks guys. I do have a bradford pear tree growing right next to where the birch was because the birch was growing into it. I live in northern missouri and these trees are quite common here.

The Missouri Botanical Garden's page on Bradford pear has a bright red warning about this plant's invasiveness in MO. Just because it is common doesn't mean it is a wise choice.

Same as eating at McDonald's.
