Just saw this post on the HK Wildlife forum about a bird at MP. I believe this bird is a juvenile Northern Goshawk and this may be relevant for the RC given that Northern Goshawk was just recently added to HK list.
This bird has been around MP for a while I think, but difficult to pin down. I saw it a few weeks ago, but was unable to get a view of much, apart from noting the straps attached to the legs. It is fairly large - larger than most accipiters.
I have seen one photo previously, similar to the photo posted here, and I also thought it looked like a Northern Goshawk. Author: lkatherine Time: 17/12/2012 16:37
A couple more photos of the same bird (taken on 7-Dec-12):
