Greenish Warbler (s)

Probably did both birds but hard to tell as they were swapping places -- really dull most of the time so a bit noisy image wise -- and just in case these make it look easy it wasn't -- I was there 8 hours and most of the time they were invisible! Believe both birds are here but its late and no time for full analysis but bill pattern seems to be different at least -- the 2nd bird is only in a few pics deep in the willow late on --
