It is a hybrid, the best way to tell is it looks like a queen with a small or missing crown. A full queen has a well developed crown with lots of small blue spots and a drk black center. If you look at the photo, the crown isn't well developed and small add to the fact that it is queen colored on the rest of the body but has streight white stripes, and it points to a townsend.
It is probably not a 50-50 hybrid, there is a fact that many don't consider when talking about townsends and that is that the townsends breed with both blue and queens, making the resulting offspring more like on parent then the other. This only adds to the confusion of identity.
