Just returned from a week near Minsmere, got my first sightings of Cetti's Warbler, Dartford Warbler, Black Tern, Woodlark, Garden Warbler, Marsh Tit, Turtle Dove and, although not a wild bird, the Greater Flamingo.
Also got to see Hummingbird Hawk-moth, Green Hairstreak, Slow Worm, Stoat, Muntjac and Red Deer in the wild for the first time too... although those are somewhat outside the topic of this thread! :-O
