Another message to Marcus Kohler (originally about the possible Firecrests)…
“…but I ran out of time as I spent over an hour grilling a mixed-singing Willow Warbler I stumbled upon. I’d always thought the mixed singers were Chiffchaffs, but this was definitely WW. It responded to CC playback by giving a CC song before transposing to WW, and responded to WW with an almost pure WW. It also went crazy when I played Iberian CC!
I also saw the Cetti’s at last and had the first Swifts (two.)”
Cetti’s Warbler (somewhere!)
