    Comments: 犭里犭九 , 洪水证人 , Paul Hyde, and I were standing in Woodcock Forest, a very heavily wooded part of Century Park, watching Great Spotted Woodpecker (itself rare in urban Shanghai).

    We saw an Accipiter flying over the treetops. We jumped out of the forest into a grassy area and saw the Accipiter soaring 100 m above the park. 犭里犭九 got the photo shown here.

    The Accipiter seemed not to be passing through Century but to be using the park; the combination of low flight over the treetops and soaring flight over the park gave me an impression of a bird that knows the area.

    As it soared, the Accipiter flapped off and on. It was confident and strong up there, but it did need to flap from time to time.

    Why I assert that the Accipiter above is Crested Goshawk:

    1. Wings short and broad and "pinched" at base--to me, the narrow wing base is obvious in the photos. Crested Goshawk is well-known for its pinched wing base. Besra, by contrast, has less of a pinched wing base, as does Eurasian Sparrowhawk.

    2. When I saw the raptor close, soaring over the treetops, the impression I got was not of a large, buzzard-sized Accipiter (as could be the impression if the raptor were Northern Goshawk). Instead, I got the impression of a smaller raptor, closer in size to a falcon. An impression of a large, Buteo-sized raptor would weigh against a diagnosis of Crested Goshawk, but an impression of a smaller raptor weighs in favor of an Accipiter the size of Crested Goshawk.

    3. Besra is less likely to be seen soaring than is Crested Goshawk.

    4. Crested Goshawk is known to occur in urban Shanghai, including Century Park, as I noted in this recent post: http://www.shanghaibirding.com/2017/09/15/goshawk/ Knowledge that Crested Goshawk is in this city does not weigh against a diagnosis of Crested Goshawk at Century today, and indeed it lends support to the idea, especially if my impression of a more or less resident Accipiter is correct.
