Goshawk stirs the birds over Wytham

Dreadful pic shows 3 Jackdaws above as the only birds brave (or foolish) enough to mob this Goshawk. 4 Buzzards, 3 Ravens, Carrion Crows, Rooks and very sensible flocks of Wood Pigeons just got out of the way! Watched for about 8 minutes but fleeing flocks of Wood Pigeons plotted its presence for about the same time afterwards. Only after it had gone and things quietened down did a tiny Sproghawk and then Red Kite dare to appear over the ridge.
The pic was a lucky snap from a compact camera thrust quickly against the scope eyepiece. At least it shows the narrow parallel sided tail, wing shape and comparative wingspan (in part). Passing Raven and exiting Buzzards had the same wingspan.
When viewed lower against the trees, the plumage was brown adult female including the white undertail coverts. The clasic lack of 'body bounce' in flight whilst battling force 5-6 winds was enough to separate this bird from female Sparrowhawk, as soon as it broke the skyline.
A couple of Teal at Pinkhill, a Ruff on the Causeway, two Grey Wags by the pumping station and 2 Mipits by the sewage treatment bank were about it excepting a couple of chiffs in with a flock of, near 50, Long-tailed, Blue and Great Tits at the NE of F1.
