HKBWS does have expertise in European birds
My friend from BirdLife International gave me advice as follows:
Pictures, number 3 is Red Kite Milvus milvus, 4 is sparrowhawk Accipiter nisus, 5 & 6 is Common Buzzard Buteo buteo, 7 is European Honey Buzzard Pernis apivorus, 8 is Common Buzzard, a pale morph, 9 & 10 are Marsh Harrier Circus aeurginosus, juveniles, 11 is Common Buzzard Buteo buteo.
By comparing advice with those from our birders friends in HKG, I am happy to say that we do have expertise in European birds. Yea yea..............
