Thanks to Keith for this great shot of a male Sparrowhawk, taken in his garden which backs on to Hilly Fields. Keith has feeders in the garden which attract many small birds, so one can see why the Sparrowhawk was lurking. The birds made themselves scarce, however, on this occasion. The reddish/orange colouring at the front and around the neck are the features that identify it as a male. The female has brown chest bars at the front and a large white stripe over the eye. The female is larger than the male as is often the case with birds of prey (eg. Kestrel and Peregrine) and has a fiercer expression!
According to the RSPB, the Sparrowhawk "is adapted to hunting birds in confined spaces like dense woodland, so gardens are ideal hunting grounds for them." And despite their name, Sparrowhawks do not just go for sparrows. Mark Cocker in Birds Britannica says: "birds form almost the entire diet of the sparrowhawk" and "more than 120 species have been recorded [as prey] from the smaller members of the tit family to the black grouse." A magnificent bird but one that can bring 'nature red in tooth and claw' right into your garden.
