I have no idea who she is. She appears in yet another stock photo. This demonstrates quite clearly that when the people who designed this template were designing this template, they had access to more than just pictures of birds.
If you're from the UK, you might think this is also a picture of a "bird", but that's because "bird" is sometimes used as a slang term in the UK for a woman.
I hope it was actually winter when the person who took this photo took this photo, because if they just made it look like winter and it was actually summer, she probably got quite warm in that jacket.
