Male Eurasian sparrowhawks regularly kill birds weighing up to 40 g (1.4 oz) and sometimes up to 120 g (4.2 oz) or more; females can tackle prey up to 500 g (18 oz) or more. A recent study found that on average, female sparrowhawk prey were two and a half times heavier than that of the male. [43]
Accipiter (/ æ k ˈ s ɪ p ə d ə r /) is a genus of birds of prey in the family Accipitridae. Most species are called sparrowhawks, but there are many sparrowhawks in other genera too, such as Tachyspiza. These birds are slender with short, broad, rounded wings and a long tail which helps them maneuver in flight.
Sparrowhawks rely on stealth and surprise to catch their prey, hunting in flight or bursting from a concealed perch among foliage. [10] Most prey weighs less than 100 g and sometimes over 200 g. It forages by short-stay perch hunting from a concealed position in foliage, punctuated by short tree-to-tree, often undulating flights. [ 10 ]
Black sparrowhawks prey primarily on mid-sized birds. [12] Most prey is spotted from a foliage-concealed perch, which is then killed in flight during a short flying dash. Less often, they stoop or chase prey seen during low or high flight over open country or near the canopy of trees and, in some cases, may even pursue prey on foot. [ 12 ]
The Goliath birdeater (Theraphosa blondi) is reputed to be an avivore (hence the name), but it rarely preys on birds. [5] [6] However, other species of spider have been observed to consume birds that they capture; large orb-weaving spiders, such as the golden orbweavers, have been observed to consume small birds such as mannikin and other finches.
Adult male Japanese sparrowhawks measure between 23–30 centimetres (9.1–11.8 in) in length with a wingspan measuring 46–58 centimetres (18–23 in), and weigh 92–142 grams (3.2–5.0 oz). [2] They have a small, curved bill, long pointed wingtips, a relatively short-tail and long, slim legs and toes. [2]
The viral picture of a man holding two geese on an Ohio street being used to fuel claims that migrants have been gobbling up pets was nothing more than a wild goose chase, according to a report.
The birds in this subfamily are primarily woodland birds that hunt by sudden dashes from a concealed perch, with long tails, broad wings and high visual acuity facilitating this lifestyle.
