What caused this ice formation in my mother's birdbath?

A few years ago, my mother sent me pictures of this odd ice formation that she found in her birdbath, wondering if I had any idea how it formed. I asked around on Facebook and none of my friends could identify it, but no such luck. I just occurred to me today to ask Ask. Here are the pictures: birdbath and close-up. Any thoughts on how that shape was created? This was winter 2010, in Connecticut.
