Long-legged buzzard, Buteo rufinus. Older birds tend to stay in the same territory; failed breeding attempts make a move more likely.

In Europe, the species suffered heavy persecution by 19th Century landowners and gamekeepers, but withstood attempts to eradicate it in the United Kingdom and Ireland, for example. Eurasian buzzard, Buteo buteo. Juveniles begin their migration earlier than adults and juvenile females move before juvenile males.Analysis of Heligoland, Germany, ringing data found that males move further and more often than females; of birds ringed at Kaliningrad, Russia, the average distance moved before recovery (when a bird is caught again by another ringer, or the ring read) was 1,328 km for males and 927 km for females. Birds from colder regions of north Europe and Asia migrate south for the winter, some to north Africa (some as far as equatorial east Africa) and India; members of the southern populations are resident or disperse. A male sparrowhawk can survive for two or three days without food, but the larger female can last for up to six days. All have long, yellow legs with black claws.The flight is a characteristic "flap-flap-glide", with the glide creating an undulating pattern. Although the average liver concentrations of polychlorinated biphenyls (PCBs) in 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 2000-2005.The Eurasian Sparrowhawk's adaptation for feeding on birds has brought it into conflict with humans. The underparts are finely barred reddish, looking plain orange from a distance; his irides are orange-yellow or orange-red.
After the post-fledging period, female birds dispersed greater distances than did males.The Eurasian Sparrowhawk has an estimated global Extent of Occurrence of between 100,000-1,000,000 square km and an estimated world population of 1 million to 10 million birds; it is one of the most common birds of prey in Europe, along with the This species is common in most woodland types in its range and also in more open country with scattered trees. The population has largely recovered to pre-decline levels, with an increase seen in many areas, for example northern Europe. The Eurasian Sparrowhawk Background Sparrowhawks (Accipiter nisus) are small birds of prey belonging to the hawk family, with about six sub-species, the nominate occurring across UK, Iberia, and Fennoscandia and east to Siberia. The musket, or musquet, originally a kind of crossbow bolt, and later a small cannon, was named after the bird because of its size.Please note: Any content published on this site is commentary or opinion, and is protected under Free Speech.

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. The typical lifespan is three years.
At between 24-28 days after hatching, the young birds start to perch on branches near the nest, though they remain dependent on their parents for 28-30 days after fledging.Most Eurasian Sparrowhawks stay on the same territory for one breeding season, though others keep the same one for up to eight years.
