The goshawk's proportions are the opposite of a falcon's. Where a peregrine has long, tapered wings for high-speed open-air pursuit, a goshawk has broad wings of lower aspect ratio and a long tail that works as a rudder and air brake. Both give rapid acceleration and tight turns in cluttered space at the cost of sustained speed.
Hunting follows the anatomy. Goshawks typically wait concealed, then attack in a short low dash, often less than a hundred metres, and pursue prey through branches and even along the ground. Failure rates are high; the payoff is that prey has almost no warning.
Taxonomy has moved recently. The North American population is now generally treated as a separate species, the American goshawk, and the genus Accipiter has been split, so Eurasian birds appear in some current sources as Astur gentilis. Names in older references are not wrong so much as superseded.
