Saker Falcon (Falco cherrug) lives in open grasslands across Eurasia Africa. It feeds on small mammals birds. Its conservation status is Endangered.
Fascinating facts about the Saker Falcon
- Saker falcons can slice through the sky at 150 km/h (93 mph) in level flight, making them the second-fastest bird on the wing, and they can dive at nearly 300 km/h (190 mph) when stooping on prey. Those speeds let them chase swift rodents across open steppes and outpace many other raptors, giving them a hunting edge that has kept them prized in falconry for millennia. Their velocity also illustrates why they need vast, open habitats to unleash their full aerial prowess.
- A mature female saker weighs between 970 and 1,300 g and spans 120-130 cm, while a male is lighter at 730-990 g with a 100-110 cm wingspan. This size gap, females up to 40 % heavier, means hunters often target females, skewing wild sex ratios. The imbalance threatens breeding success because fewer females are left to lay the 3-6 eggs each pair can produce, underscoring how cultural preferences can ripple into population decline.
- Sakers lay 2 to 6 eggs per clutch, usually 3-5, and incubation lasts about 32-36 days. After hatching, chicks stay in the nest for 45-50 days before their first flight, then depend on parents for another 30-45 days. Heavy losses, such as the estimated 1,000 birds taken annually in Kazakhstan, have been reported.
- Sakers are highly vulnerable to avian influenza; infections with H5N1 in Saudi Arabia and H7N7 in Italy have been recorded. In a vaccine trial, five vaccinated birds survived a lethal H5N1 challenge while five unvaccinated birds died, showing that targeted vaccination can protect captive birds.
- The global saker population was estimated at just 7,200-8,800 mature individuals in 2004, and numbers keep falling because illegal trapping removes up to 1,000 birds each year in Kazakhstan alone.
