For example, great tits and house sparrows are vulnerable to attack. The chemicals accumulated in the bodies of grain-eating birds and had two effects on top predators like the Eurasian sparrowhawk and peregrine falcon: the shells of eggs they laid were too thin, causing them to break during incubation;[37] and birds were poisoned by lethal concentrations of the insecticides. "[97], In Slavic mythology, the sparrowhawk, known as krahui or krahug, is a sacred bird in Old Bohemian songs and lives in a grove of the gods. An evening in the garden with a glass of wine wouldn't be complete without the smell of freshly cut grass and bird song all around us. 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. The Hawk replied: 'I will not lose my diet, To let a thousand such enjoy their quiet. [77] When the Eurasian sparrowhawk population declined because of organochlorine use, there was no great increase in the populations of songbirds. All rights reserved. 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. [88], The Eurasian sparrowhawk has been used in falconry for centuries and was favoured by Emperor Akbar the Great (15421605) of the Mughal Empire. If a winter sparrowhawk prove good, she will kill the pye, the chough, the jay, woodcock, thrush, black-bird, fieldfare, and divers[e] other birds of the like nature. [86], The findings, released in January 2010,[87] showed that only seven Eurasian sparrowhawks had been removed from the area from five pigeon lofts. There are fewer birds in the winter, so they do sometimes go for small rodents like mice and voles, but this is quite rare. [36] Unlike its larger relative the northern goshawk, it can be seen in gardens and in urban areas[37] and will even breed in city parks if they have a certain density of tall trees. Ah, when we hear bird songs in the summer, it is a wonderful noise. [19] The Norwegian and Albanian populations are declining and, in many parts of Europe, Eurasian sparrowhawks are still shot. Older birds tend to stay in the same territory; failed breeding attempts make a move more likely. So, below, we're looking at what sparrowhawks have for breakfast, lunch, and dinner, and it might surprise you. [99] The name Spearhafoc (later Sparhawk, Sparrowhawk) was in use as a personal name in England before the Norman conquest in 1066. [44], Male Eurasian sparrowhawks regularly kill birds weighing up to 40g (1.4oz) and sometimes up to 120g (4.2oz) or more; females can tackle prey up to 500g (18oz) or more. If a clutch is lost, up to two further eggs may be laid that are smaller than the earlier eggs. Like other birds of prey, Eurasian sparrowhawks produce pellets containing indigestible parts of their prey. They aren't their main diet, but a sparrowhawk has no problem hunting on their feet and will happily have a mouse for dinner. Though it is a predator which specialises in catching woodland birds, the Eurasian sparrowhawk can be found in any habitat and often hunts garden birds in towns and cities. Adult male Eurasian sparrowhawks have bluish grey upperparts and orange-barred underparts; females and juveniles are brown above with brown barring below. The Old Norse name for the Eurasian sparrowhawk, sparrhaukr, was thought to have been coined by Vikings who encountered falconry in England. As females are larger than males, they can actually take quite large birds too. [17], It waits, hidden, for birds to come near, then breaks cover and flies out fast and low. The horizontal barring seen on adult Eurasian sparrowhawks is typical of woodland-dwelling predatory birds, while the adult male's bluish colour is also seen in other bird-eating raptors, including the peregrine falcon, the merlin and other Accipiters. [5] English folk names for the Eurasian sparrowhawk include blue hawk, referring to the adult male's colouration, as well as hedge hawk,[6] spar hawk, spur hawk and stone falcon. It can "stoop" onto prey from a great height. The structure, made of loose twigs up to 60cm (2.0ft) long, has an average diameter of 60cm (24in). They may take it to a safer location if absolutely necessary. [17], 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 habitat conserved with gamebirds in mind also suited this species and its prey; gamekeepers' more successful efforts to wipe out the northern goshawk and pine marten predators of the Eurasian sparrowhawk may have benefited it. A sparrowhawk in the nest with their chicks. Sparrowhawks have about 120 species of birds that they call prey, and magpies are on that list.

So, most of the birds they eat are either injured, old or sick. [62], The Eurasian sparrowhawk population in Europe crashed in the second half of the 20th century. [89] At Cap Bon in Tunisia, and in Turkey, thousands are captured each year by falconers and used for hunting migrant common quails. It was criticised by the government's own ecological adviser, Dr Ian Bainbridge, the government body Scottish Natural Heritage[84] and organisations including the Royal Society for the Protection of Birds[85] and the Scottish Society for Prevention of Cruelty to Animals. Although global population trends have not been analysed, numbers seem to be stable, so it has been classified as being of least concern by IUCN. Eurasian reed warblers were found to be more aggressive to cuckoos which looked less hawk-like, meaning that the resemblance to the hawk (mimicry) helps the cuckoo to access the nests of potential hosts.

Sparrowhawks will often leave a fresh kill halfway through and return to it later. Holy sparrowhawks perch on the branches of an oak tree that grows from the grave of a murdered man, and "publish the foul deed. One hawk returned twice to the area of the loft, while new birds began to visit two other lofts. Seen a bird and not sure what it was? [70], Body tissue samples from Eurasian sparrowhawks are still analysed as part of the Predatory Bird Monitoring Scheme conducted by the UK government's Joint Nature Conservation Committee. The young hawks disperse after their parents stop provisioning them. A female Eurasian sparrowhawk is considered a bad choice for a novice and the male is very difficult and demanding, even for an experienced handler. [32] It is one of the most common birds of prey in Europe, along with the common kestrel and common buzzard. However, a few clever wildlife photographers have figured out that you can use the carcass of a fresh kill. [59] 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. Baby sparrowhawks are just as fussy eaters as their parents, but it is their parent's behaviour that is responsible for this in the first place. [65], In the United Kingdom, for example, the species almost became extinct in East Anglia, where the chemicals were most widely used; in western and northern parts of the country, where the pesticides were not used, there were no declines. [17] A study in a forested area of Norway found that the mean size of the home ranges was 9.2km2 (3.6sqmi) for males, and 12.3km2 (4.7sqmi) 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 [Norwegian study area]". The results of the study indicated that patterns of year-to-year songbird population change were the same at different sites, whether the predators were present or not. However, these will scare the other birds in your garden too. They are many rumours about sparrowhawks and what they eat, and it is time for these rumours to be answered. So, they eat birds too, only a bird that's already been inside of another bird! While about 98% of a sparrowhawks diet is birds, they will hunt mammals too, and the occasional rabbit is taken. [92] The falconer's name for a male Eurasian sparrowhawk is a "musket"; this is derived from the Latin word musca, meaning 'a fly', via the Old French word moschet. Anywhere that sparrowhawk feels safe is where lunch will take place. Although the average liver concentrations of polychlorinated biphenyls (PCBs) in Eurasian sparrowhawks were lower in birds that died in 2005 compared to those that died in 2004, there was not a significant or consistent decline in residues between 20002005. Their young, though, is taken by pine martens and goshawks. No, sparrowhawks are meat-eaters, and they get their nutrients from the seeds, nuts and berries that their prey eats. [10] After hatching, the female cares for and feeds the chicks for the first 814days of life, and also during bad weather after that. It is birds, birds and more birds, with the occasional bat thrown in to keep things interesting. "[75] Parish records of the 18th century for Aldworth, Berkshire, in southern England, show that payments were made for 106 Eurasian sparrowhawks' heads, at the same time as efforts were being made to control the numbers of sparrows. [61] 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. [12] Geographic variation is clinal, with birds becoming larger and paler in the eastern part of the range compared to the western part. "[98] In some areas of England, it was believed that the common cuckoo turned into a Eurasian sparrowhawk in winter. It also makes use of gardens in built-up areas, taking advantage of the prey found there. [9] The current scientific name is derived from the Latin accipiter, meaning 'hawk' and nisus, the sparrowhawk. Falconers have utilised the Eurasian sparrowhawk since at least the 16th century; although the species has a reputation for being difficult to train, it is also praised for its courage. T'was considered very ominous, and so it proved. [67], In the UK, the failure rate at the egg stage had decreased from 17% to 6% by the year 2000, and the population had stabilised after reaching a peak in the 1990s. The increase in population of the Eurasian sparrowhawk coincides with the decline in house sparrows in Britain. Most of the Old World members of the genus are called sparrowhawks or goshawks. [14] She has dark brown or greyish-brown upperparts, and brown-barred underparts, and bright yellow to orange irides. [20], The adult male is 2934cm (1113in) long, with a wingspan of 5964cm (2325in)[10] and a mass of 110196g (3.96.9oz). Eurasian sparrowhawks breed in suitable woodland of any type, with the nest, measuring up to 60cm (2.0ft) across, built using twigs in a tree. [60] In a study in the Forest of Ae, 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. Yes, sparrowhawks do eat blackbirds, and they make up a good percentage of their diet. But sparrowhawks are not going to willingly pick a fight with another predator. This could be a tree stump, high up in a tree, or even in tall grass. [19] The increased proportion of medium-aged stands of trees created by modern forestry techniques have benefited Accipiter nisus, according to a Norwegian study. They are best suited for small quarry such as common starlings and common blackbirds but are also capable of taking common teal, Eurasian magpies, pheasants and partridges. Sparrowhawks, (Accipiter nisus), are one of the most beautiful birds in the UK. [23], The Eurasian sparrowhawk's small bill is used for plucking feathers and pulling prey apart, rather than killing or cutting. However, this low-level persecution has not affected the populations badly. Juveniles begin their migration earlier than adults and juvenile females move before juvenile males. They are extremely good at spotting movement. The trial, which cost 25,000, was supported by the Scottish Homing Union, representing the country's 3,500 pigeon fanciers. And in my song I'll praise no bird but thee.' And as they don't sweat, they don't waste too much water. When the eggs are laid, a lining of fine twigs or bark chippings is added. View identification guides for birds that can be found around the world. [14] He has slate-grey upperparts (sometimes tending to bluish), with finely red-barred underparts, which can look plain orange from a distance; his irides are orange-yellow or orange-red. In a 19491979 study of 13 passerine species breeding in a 40-acre (16-hectare) oakwood at Bookham Commons, Surrey, England, none was present in significantly greater numbers when Eurasian sparrowhawks were absent from the wood. [93], "An austringer [falconer] undertaking to train a sparrowhawk should be in no doubt that he is taking on one of the most difficult hawks available." Its long legs and toes are an adaptation for catching and eating birds. A change of mate usually triggers the change in territory. ", "Pigeon lovers pin hopes on sequins to repel predators", "Report shows birds of prey take few pigeons", "Bid to save pigeons from sparrowhawks provokes legal warning", "About SNH: What is Scottish Natural Heritage? Organochlorine insecticides used to treat seeds before sowing built up in the bird population, and the concentrations in Eurasian sparrowhawks were enough to kill some outright and incapacitate others; affected birds laid eggs with fragile shells which broke during incubation. [11], The Eurasian sparrowhawk forms a superspecies with the rufous-chested sparrowhawk of eastern and southern Africa, and possibly the Madagascar sparrowhawk.
