Bird pattern maroon button up dress shirt

all the tags are cut off of this shirt. I've tried to reverse look it up but I've found nothing except that Adam Levine sold shirts with a very similar pattern some years ago. the shirt is very well made and the stitch work is good. it has one missing button but the extra is still attached. if I can find matching tread I'll reattach it myself. I believe it's 100% cotton or maybe a Rayon blend.
