A very interesting thread.
Whilst not wishing to compete with any other subscriber's Garden List, I offer the following sightings from my "plot"out of interest: Wryneck, Black WP, Black Kite, Pallas's Wblr, Crested Tit, GGS, Gt White Egret, Hobby, Honey Buzzard, Goshawk and Osprey. RBS missed by only 50 mtrs (view obscured by trees), and twice yearly overhead passage of up to 10,000 Common Cranes on migration.
Regular nesting birds on my plot include Whitethroat, Gdn Wblr, Blackcap, Willow Wblr, Chiff-Chaff, Alba Wag, MSWP, Black Redstart and ST Treecreeper.
Having relocated here only a few short years ago, and accutely aware of the extent to which the area is "underwatched", I am still wondering what will turn up next - a great buzz with each new season. Good luck to all garden listers.
