Is a Bradford pear tree evergreen or deciduous?

Deciduous is the classification for the Bradford pear tree (Pyrus calleryana).

Specifically, deciduous trees grow and lose their leaves in less than a year. Evergreens also grow and lose their foliage, but generally over the course of a couple of years. The Bradford pear always grows and drops its foliage in less than a year. Therefore, it is deciduous, not evergreen.
