which hawk ?

Greetings, all.

Here are measurements for an Accipiter found dead yesterday on the back landing here, beneath a hard-sheltered water bowl frequented by local passerines. These measurements I’ve compared with the following refs (& their diagrams), reaching an uncertain conclusion—
Menkhorst et al, 2017
Simpson & Day, 2004
Debus, 1998
Morcombe, 2000

The bird’s neck is broken. In the hand it feels broad-shouldered & “heavy”. Puzzlingly the beak & cere are all-black, with just the slightest whitish thread separating them.

Ventrally, chest-down the bird is finely barred rufous/white. There is a chestnut breast-band > slight dorsal half-collar. Dorsally the bird is brownish grey, & the head slate-grey. Brow-ridges are distinct. Tail is barred with a ventral bluish cast.

Measures are in CENTIMETRES, taken with a retracting metal household tape:

LENGTH bill>tail-tip 37
WEIGHT 257g

WINGspan 56 ventrally (incl. chest)
Single wingspread 30 dorsally (longest flight-feather > shoulder joint)

TAIL appears notched —
17.5 dorsally (from feather-base), 17 ventrally (from below cloaca)

BILL 1.5 (+cere=2)
Middle TOE 4.4 (incl. claw): appears longer by one-third than the neighbouring two. (Cannot be well-measured due to rigor, & damage.)

Two choices… What do you think?
