Animated Flying Twitter Bird Widget not working correctly on wordpress?

[RajkumarLA]

Added animated twitter bird widget code on site.. the bird appears on the site.. but when the bird moves the animation seems out of sink, not smooth..
Have a look at the site. you'll notice the problem when the bird moving...
