Etymology
Preen is probably a variant of Middle English proinen, used for trimming feathers or carefully grooming oneself. The self-satisfaction sense turns attention to one's appearance into an outward display of pride.
In context
before I could preen she was up and across in two strides, snatching the pheasant and three doves from me
