Large owl of some sort spotted in South Lantau Road

A rather large owl of some sort decided to take flight from the trees at the side of the road as I came down from Nam Shan to Mui Wo on my motorbike last night.   It was brown, big and just seemed to cruise in front of me for a couple of seconds before disappearing into the trees on the other side of the road.    Great to see it but just too dark and quick to be able to get any detail.   Its back and tail feathers seemed quite light brown but that may have been the effects of the street lighting.  I guess t was either a fish owl, a brown wood owl or possible an eagle owl.
