Kestrel vs Sparrowhawk: How to Tell Them Apart

The quickest clue is behaviour: a Kestrel hovers in place over open ground while hunting, whereas a Sparrowhawk dashes low and fast on broad, rounded wings. Compare their size, plumage, habitat and calls side by side below, or open each species for the full profile.
