Hi Faz,
There has been a single Waxwing in Alphington for several days (at least until yesterday), in the Steeple Drive/Chantry Meadow area. Otherwise, a few in the Torbay area (including five today) but these don't seem to be hanging around.
I'll try and let you know if any more reach Devon, some sightings (and other birds) will be posted on this free to access county bird news site though:
