Now where I was caught out is that I now know that it would have been useful to take more measurements than I actually did and especially of the tail. A bit of a cock-up with hindsight but then there is so much overlap between the subspecies they may not have helped anyway. The wing length of 64mm means it wasn't particularly small but it could still be OK for straminea, just. At the time I was more concerned about confirming that it was actually a Grasshopper Warbler as it looked so different. However, I did take a good series of photographs as I thought it may be identifiable as to the subspecies on its appearance alone.
Further enquiries are currently being made to see if it can be attributed to one of the eastern subspecies although we may only be able to say that it showed some characters of an 'Eastern type' Grasshopper Warbler. Unfortunately it didn't drop a feather so taking the DNA route isn't an option. A remarkable bird whichever way you look at it and one that seems likely to spark quite a bit of debate over its appearance and origin although it may well remain a mystery bird. I will keep you posted when I get some feedback from my enquiries.
