In my back yard:  Rose Breasted Grosbeak, and that includes it's gorgeous "stop me dead in my tracks" spring song.

In England:  Fulmars, soaring stiff-winged around the cliffs of Cornwall.  (Still hoping to see a Chough in the wild.) And I am very partial to Mute Swans for elegance of line & motion.
