[Nightjar] Grey Nightjar over HKU

Grey Nightjar over HKU

Tonight, 3 Aug 2010, 7:45 pm, I had a Nightjar flying over a well lit part of Pokfulam Road near HKU. It was flying strait Southwest and I assume it must be a migrant. I identified it as a Grey Nightjar due to the lack of white wing bars and lack of white outer tail feathers.  I have not found many pictures of Grey Nightjars in flight but I would say the overall appearance was very to this bird photographed near Po Toi ... &extra=page%3D9

Every picture of Savannah Nightjar I can find have very a prominent white wing bars.
