With a strong passage of Balearic Shearwaters in the channel today, it wasn't a surprise I saw a handful late afternoon. All birds appeared very dark in cloudy conditions, and going east they were motoring shearing with the wind. Very little else moving.
16.30-17.30 Wind SW 6-7
Balearic Shearwater - 4E (3@ 4.42 & 1@ 4.45)
Earlier in Thessaloniki over the terminal were several Pallid Swifts and Yellow-legged Gulls.
