Redstarts and lots more

LFGP produced another Black Necked Grebe, a winter adult individual, so two records in one year after 12 years without one. A distant Wheatear on the vents to almost furthest vent to East, plus a mystery chat like bird to the far SE vent. Later a Redstart appeared in the car park field and may have been said mystery bird. Raptors overhead included Hobby, 5 Buzzard and Sparrowhawk. After I left a juvenile Cuckoo dropped in and perched for a while. We await a confirmed Whinchat and twitchable Spotted Flycatcher.
