The ferruginous hawk is a well-regarded falconry bird, though not recommended for beginners due to its large size, power, and aggressive personality. [45] For the experienced falconer it offers an opportunity to experience the nearest equivalent to hunting with the golden eagle with much lower risk of injury to the falconer by the hawk.
The Northrop Grumman RQ-4 Global Hawk is a high-altitude, ... Size comparison for the RQ-4A and RQ-4B models. Data from Northrop Grumman [173] USAF [11]
Although often described as long-winged, [3] [5] the proportional size of the wings is quite small and red-tails have high wing loading for a buteonine hawk. For comparison, two other widespread Buteo hawks in North America were found to weigh: 30 g (1.1 oz) for every square centimeter of wing area in the rough-legged buzzard (B. lagopus) and ...
Comparison of a male Cooper's hawk (left) with prey and a female sharp-shinned hawk (right) with prey. Both prey items are about one third the weight of the respective hawks. As for the northern goshawk, the smallest male is still usually "clearly" larger than most large female Cooper's hawks. [2]
(Two supernormal clutches of eight eggs and one of nine have been documented. One egg in one of the eight-egg clutches hatched as did one egg in the nine-egg clutch.) [54] The average egg size is 32 mm × 29 mm (1.3 in × 1.1 in), 10% larger than average for birds of its body size. The eggs are white to cream in color with brown or grey splotching.
In direct comparison, it is typically larger and longer proportioned than the broad-wing, though is slightly smaller and more slender than most other common North American Buteo species. This bird is sometimes also confused with the widespread red-tailed hawk. That species is larger and bulkier, with more even-sized, broad wings, and is paler ...
The distinctive plumage and tail feathers clearly confirm that this is a Harris's hawk. This medium-large hawk is roughly intermediate in size between a peregrine falcon (Falco peregrinus) and a red-tailed hawk (Buteo jamaicensis). Harris's hawks range in length from 46 to 59 cm (18 to 23 in) and generally have a wingspan of about 103 to 120 cm ...
At 34–45 centimetres (13–18 in) in length and 200–450 grams (7.1–15.9 oz) in weight, it is significantly smaller than the northern goshawk of Eurasia and North America, and somewhat smaller than the Cooper's hawk of North America, but it is among the largest hawks in Central and South America (only the rare grey-bellied hawk is larger).
