In Order of Appearance:

Dan here with a mid-season list of which summer migrants we've recorded in the parish so far. In order of appearance:

March
11th  Chiffchaff
19th  Little Ringed Plover
25th  Blackcap
27th  Osprey
29th  Willow Warbler
30th  Wheatear
31st  Sand Martin
April
3rd    Lesser Whitethroat
4th    Ring Ouzel
15th  Swallow
15th  White Wagtail
15th  Tree Pipit
15th  Yellow Wagtail
16th  Whitethroat
16th  Common Sandpiper
17th  Sedge Warbler
17th  House Martin
22nd Whimbrel
24th  Whinchat
24th  Redstart
25th  Cuckoo
May  
5th    Swift
5th    Arctic Tern
8th    Woodchat Shrike
8th    Garden Warbler

For the sake of simplicity, purity and argument I've only included classic summer migrants and not proto-, partial-, hemi- and demi-migrants such as Stonechat and Greenshank...

Ring Ouzel, Cuckoo and even Yellow Wagtail are not always annual at Aldcliffe so we've been lucky with those, but we've usually recorded Grasshopper Warbler & Garden Warbler by now--particularly in a spring with plentiful observer coverage like this one.

Hopefully there are plenty more spring additions to come and perhaps I'll complete the round-up towards the end of June.
