I think this is your best shot pic. i vote for this.Distracting background is pretty much blur. kind of images i like. Some of your pics are pretty high quality.while others need either flash exposure bracketing just to fill a touch of a light as if u didn't use flash. Also, u might wanna try to take from different angle to catch its magic moment to get the best pic although not easy to take birds picture. But patience pays off. check this www.birdsasart.com of arthur morris for bird photography if u r not aware of it.
overall, very nice pics.
