100 square kilometers. Populations worldwide are now viewed as stable and Eurasian sparrowhawks currently face no major threats. There are six recognized subspecies of A. nisus. They are A. nisus nisus, A. nisus nisomilis, A. nisus melaschistos, A. nisus wolterstorff, A. nisus granti, and A. nisus punicus

Accipiter minullus African little sparrowhawk; little sparrowhawk

the very closely related Eurasian Sparrowhawk (Accipiter nisus) live for about four years in the wild. The oldest individual of A. nisus lived to twenty years in captivity (Robinson 2005). Accipiter minullus are primarily a solitary species (The Kruger National Park 2014). If they are seen together it is usually a mated pair sharing the same territory. Little Sparrowhawks do not migrate and remain in their territory year-round (Kemp and Marks 2020). Accipiter minullus is regarded as quiet birds. Male and

Accipiter gentilis northern goshawk

and small open areas within the forest for foraging. During the cold winter months they migrate to warmer areas, usually at lower elevations. Northern goshawks are the largest species of the genus Accipiter. Males generally weigh between 630 and 1100 grams, average 55 cm in length, and have a wingspan ranging from 98 to 104 centimeters. Females are slightly larger, weighing, on average, between 860 and 1360 grams, and having a wingspan of 105 to 115 centimeters and an average length of 61 cm. All accipiters

Accipitridae eagles, hawks, and kites; hawks, eagles, and relatives

one to two eggs, where as smaller accipiters and harriers normally lay clutches of five to six eggs. Birds that nest farther from the equator generally lay larger clutches than equatorial individuals of the same species. In many species, especially rodent specialists, clutch size also tends to track prey abundance. One egg is laid every two to five days, and incubation begins with the first or second egg. Length of the incubation period differs considerably between species, and lasts from 28 to 60 days

Falco tinnunculus common kestrel

falcons (Falco peregrinus), sparrowhawks (Accipiter nisus), eagle owls (Bubo bubo) and tawny owls (Strix aluco). In some areas, common kestrels are key predators of small, herbivorous mammals, including voles and mice, and help control rodent and small mammal populations. Although they fall prey to goshawks and other raptors, they are not a primary food source for raptors. Common kestrels are important in controlling agricultural pests, especially mice and voles. They are also used in falconry. There are no

Regulus regulus goldcrest

while foragaing, they are rarely subject to predation. Goldcrests use cryptic coloration to blend into their environment. The most common predators of the goldcrest are owls, such as the pygmy owl Glaucidium passerinum, and sparrow hawks Accipiter nisus. Regulus regulus plays a role in seed dispersal by caching seeds. The trematode Collyriclum faba is a common parasite in wild birds including Regulus regulus. This parasite can cause one to twenty-one cysts in the body and can be fatal to the bird. In

Bombycilla garrulus Bohemian waxwing

preferred food sources are less abundant, they feed on flowers and sap from trees. Bohemian waxwings are preyed on mainly by birds of prey, including merlins (Falco columbarius), which prey extensively on winter flocks, prairie falcons (Falco mexicanus), rough-legged hawks (Buteo lagopus), and Eurasian sparrowhawks (Accipiter nisus). When approached, Bohemian waxwings adopt a cryptic posture with neck and bill extended skyward while they remain very still. If the cryptic posture fails to be effective, they

Cuculus canorus common cuckoo; Eurasian cuckoo

Common cuckoos eat different types of insects, including hairy caterpillars which are not eaten by many other birds for despite their bitter taste. Their diet also includes crickets, beetles, larva, and dragonflies. Female cuckoos also eat the eggs and the nestlings of the host species. Adult cuckoos do not have any known predators, but chicks are attacked by crows and cats some time. Adults resemble dangerous prey birds such as sparrow hawk (Accipiter nisus) and other raptor species, depending on the

Calidris maritima purple sandpiper

breeding season. Top predators during this time are arctic foxes (Alopex lagopus) and jaegers (Stercorarius parasiticus). During the winter, large birds of prey such as Eurasian sparrowhawks (Accipiter nisus), northern goshawks (Accipiter gentilis), and gyrfalcons (Falco rusticolus) attack adults. When approached by a predator at the nest, the incubating bird will lower its head and try to stay on the nest as long as possible. If the predator continues to get closer, the purple sandpiper will first give an

Perdix perdix grey partridge

include the northern goshawk (Accipiter gentilis), sparrowhawk (Accipiter nisus), Eurasian eagle-owl (Bubo bubo), common buzzard (Buteo buteo), marsh harrier (Circus aeruginosus), northern harrier (Circus cyaneus), Montagu's harrier (Circus pygargus), peregrine falcon (Falco peregrinus), red kite (Milvus milvus), and tawny owl (Strix aluco).Nesting females, eggs, and hatchlings are susceptible to predation and nest destruction during breeding season from terrestrial mammals and birds, including domestic dog

Ficedula hypoleuca European pied flycatcher; pied flycatcher

learn the mobbing call and respond to it, coming to attack the nests of birds while they are busy attacking the original intruder. Stoats (Mustela erminea), least weasels (Mustela nivalis), and martens (Martes) raid nests. Goshawks (Accipiter gentilis), Eurasian sparrowhawks (Accipiter nisus), and tawny owls (Strix aluco) prey on fledgling and adult pied flycatchers. Mobbing is reciprocal. When a bird hears the mobbing call, it may choose to assist or not. Assisting in mobbing behavior is dangerous, so some

Apus apus common swift

sparrowhawks (Accipiter nisus), and buzzards (Buteo buteo), by taking to the air. In addition, the choice of nesting sites on vertical surfaces such as rock walls and chimneys makes it difficult for common swifts to be preyed upon because of the level of difficulty associated with accessing the nest area. The plain coloration of Apus apus also is advantageous for predator evasion as it makes them difficult to see when they are not in the air. As a predator, A. apus contributes to the control of the insect

Turdus merula common blackbird; Eurasian blackbird

sparrowhawks (Accipiter nisus) because the European blackbird commonly searches for food located on the ground in open and unprotected areas. In the breeding season, female blackbirds tend to spend more time in search of food compared to males, which lends to the increasing amount of female deaths from predation. Other known predators include domestic cats (Felis catus), weasels and foxes. Nest predators of the blackbird include the Eurasian magpie (Pica pica), Eurasian jay (Garrulus glandarius), and the

Arenaria interpres ruddy turnstone

predators of adults are Eurasian sparrow-hawks (Accipiter nisus), peregrine falcons (Falco peregrinus), merlins (Falco columbarius), and owls (Strigiformes). Ruddy turnstones are important predators of insects and other invertebrates in their tundra breeding habitats and crustaceans and mollusks in coastal habitats at other times of the year. There are few parasites recorded in ruddy turnstones, only some records of nematode infections. Ruddy turnstones are interesting and charismatic members of coastal
