; while birds from the northern parts of the range migrate south for winter, their southern counterparts remain resident or make dispersive movements. Eurasian sparrowhawks breed in suitable woodland of any type, with the nest, measuring up to across, built using twigs in a tree. Four or five pale blue, brown-spotted eggs are laid; the success of the breeding attempt is dependent on the female maintaining a high weight while the male brings her food. The chicks hatch after 33 days and fledge after 24 to 28 days. The probability of a juvenile surviving its first year is 34%, with 69% of adults surviving from one year to the next. Mortality in young males is greater than that of young females and the typical lifespan is four years. This species is now one of the most common birds of prey in Europe, although the population crashed after the Second World War.

The juvenile is warm brown above, with rusty fringes to the upperparts; and coarsely barred or spotted brown below, with pale yellow eyes; its throat has dark streaks and lacks a mesial (midline) stripe. The Eurasian sparrowhawk's pale underparts and darker upperparts are an example of

) helps the cuckoo to access the nests of potential hosts. The Eurasian sparrowhawk's small bill is used for plucking feathers and pulling prey apart, rather than killing or cutting. Its long legs and toes are an adaptation for catching and eating birds. The outer toe is "fairly long and slender"; the inner toe and back toe are relatively short and thick. The middle toe is very long and can be used to grasp objects, while a protuberance on the underside of the toe means that the digit can be closed without leaving a gap, which helps with gripping. The flight is a characteristic "flap-flap-glide", with the glide creating an undulating pattern. This species is similar in size to the

Lifespan and demography

The oldest known wild Eurasian sparrowhawk lived more than two decades; it was found dead in Denmark 20 years and 3 months after having been ringed. The typical lifespan is four years. Data analysis by the
British Trust for Ornithology The British Trust for Ornithology (BTO) is an organisation founded in 1932 for the study of birds in the British Isles. The Prince of Wales has been patron since October 2020. History Beginnings In 1931 Max Nicholson wrote: In the United Stat ...
shows that the proportion of juveniles surviving their first year of life is 34%; adult survival from one year to the next is 69%. Birds in their first year of life weigh less than adults, and are especially light in the first two months after reaching independence. There is probably high mortality, especially for young males, during this time. A study in southern Scotland suggested that the greater mortality in young male birds may be due to their smaller size and the smaller size of their prey, which means that they can "last less long between meals". Their size also means that their range of prey is restricted. It has been estimated that a female Eurasian sparrowhawk of average weight could survive for seven days without feeding – three days longer than a male of average weight. A study of female Eurasian sparrowhawks found "strong evidence" that their rate of survival increased for the first three years of life, and declined for the last five to six years.

It waits, hidden, for birds to come near, then breaks cover and flies out fast and low. A chase may follow, with the hawk even flipping upside-down to grab the victim from below or following it on foot through vegetation. It can "stoop" onto prey from a great height.

s, are sometimes caught but insects are eaten only very rarely. Small birds are killed on impact or when squeezed by the Eurasian sparrowhawk's foot, especially the two long claws. Victims which struggle are "kneaded" by the hawk, using its talons to squeeze and stab. When dealing with large prey species which peck and flap, the hawk's long legs help in restraining the prey. It stands on top of its prey to pluck and pull it apart. The feathers are plucked and usually the breast muscles are eaten first. The bones are left, but can be broken using the notch in the bill. Like other birds of prey, Eurasian sparrowhawks produce pellets containing indigestible parts of their prey. These range from long and wide and are round at one end and more narrow and pointed at the other. They are usually composed of small feathers, as the larger ones are plucked and not consumed. During hunting, this species can fly per day. It rises above tree level mostly to display, soar above territory and to make longer journeys. A study in a forested area of Norway found that the mean size of the home ranges was for males, and for females, which was larger than studies in Great Britain had found, "probably due to lower land productivity and associated lower densities of prey species in the orwegian study area.

The size of the breeding population was not changed, but there were fewer non-breeding blue tits in the population. In woodland, Eurasian sparrowhawks account for the deaths of a third of all young great tits; the two alarm calls given by great tits when mobbing a predator, and when fleeing from a nearby hawk, are within the optimum hearing range of both prey and predator; however, the high-pitched alarm call given when a distant flying Eurasian sparrowhawk is seen "can only be heard well by the tit".

Breeding

The Eurasian sparrowhawk breeds in well-grown, extensive areas of woodland, often coniferous or mixed, preferring forest with a structure neither too dense nor too open, to allow a choice of flight paths. The

are laid, a lining of fine twigs or bark chippings is added. During the breeding season, the adult male Eurasian sparrowhawk loses a small amount of weight while feeding his mate before she lays eggs, and also when the young are large and require more food. The weight of the adult female is highest in May, when laying eggs, and lowest in August after the breeding cycle is complete. A study suggested that the number of eggs and subsequent breeding success are dependent on the female maintaining a high weight while the male is feeding her.

is reached at between 1–3 years. Most Eurasian sparrowhawks stay on the same territory for one breeding season, though others keep the same one for up to eight years. A change of mate usually triggers the change in territory. Older birds tend to stay in the same territory; failed breeding attempts make a move more likely. The birds which kept the same territories had higher nest success, though it did not increase between years; females which moved experienced more success the year after changing territory.


Eggs

The eggs are pale blue with brown spots and each measure x , and weigh about of which 8% is shell in a healthy egg. Usually a clutch of four or five eggs is laid. The eggs are generally laid in the morning with an interval of 2–3 days between each egg. If a clutch is lost, up to two further eggs may be laid that are smaller than the earlier eggs.

, downy chicks hatch after 33 days of incubation. After hatching, the female cares for and feeds the chicks for the first 8–14 days of life, and also during bad weather after that. The male provides food, up to six kills per day in the first week increasing to eight per day in the third and 10 per day in the last week in the nest, by which time the female is also hunting. By 24–28 days after hatching, the young birds start to perch on branches near the nest and take their first flight. They are fed by their parents for a further 28–30 days, staying close to the nest while growing and practicing flying. At this stage they are extremely vocal, and their cries to their parents can often be heard a considerable distance away. The young hawks disperse after their parents stop provisioning them. Though they receive the same amount of food, male chicks (roughly half the size of females) mature more quickly and seem to be ready to leave the nest sooner. In a study in the

, south-west Scotland, it was found that 21% of nestlings over two days old died, with the causes of death being starvation, wet weather, predation and desertion by the parents. The parasite ''Leucocytozoon toddi'' can be passed from parent to nestling at the nest, possibly because of the number of birds sharing a small space, thus allowing transmission.

Conflict with humans

The Eurasian sparrowhawk's adaptation for feeding on birds has brought it into conflict with humans; in the 19th century it was described as "the great enemy of small quadrupeds and birds, and often very destructive to young chicks in poultry-yards in the breeding season" and "very destructive to partridges". Writing for gamekeepers in 1851, T. B. Johnson recommended that: "The nest of this bird should be diligently sought ... and destroyed, shooting the parent birds first, if possible." It was written in 1870 that "The sparrowhawk is perhaps only the true enemy of the game-preserver; though at the same time it is probable that if the good and evil it does were justly weighed, the balance would be in favour of the hawk, its favourite quarry being the wood pigeon, which is now increasing to an extent injurious to agriculture."

Many studies, mostly short-term, failed to find an effect on songbird populations caused by predatory birds such as Eurasian sparrowhawks. But analysis of long-term, large-scale national data from the UK's Common Bird Census demonstrated that the declines in farmland songbird populations since the 1960s are unlikely to have been caused by increased predation by Eurasian sparrowhawks and magpies.

The findings, released in January 2010, showed that only seven Eurasian sparrowhawks had been removed from the area from five pigeon lofts. One hawk returned twice to the area of the loft, while new birds began to visit two other lofts. The report found that "The quantity and quality of the observational data collected meant that it was impossible to draw any firm conclusions" and the government stated that "no further research involving the trapping or translocation of raptors" would take place, while the SHU maintained that it was "very optimistic that licensed trapping and translocation could at last provide some protection." Eurasian sparrowhawks are an effective urban adapter species in the UK and are thus non-threatened, however, recent search has suggested that they are prone to colliding with man-made structures when hunting such as buildings.
