The kestrel has also been reported to have killed scorpions, snakes, [40] bats, [41] and squirrels. [42] The kestrel is able to maintain high population densities, at least in part because of the broad scope of its diet. The American kestrel's primary mode of hunting is by perching and waiting for prey to come near.
The common kestrel (Falco tinnunculus), also known as the European kestrel, Eurasian kestrel or Old World kestrel, is a species of predatory bird belonging to the kestrel group of the falcon family Falconidae. In the United Kingdom, where no other kestrel species commonly occurs, it is generally just called "kestrel". [2]

Greater kestrels use the old nest of another bird for breeding, such as that of a Cape crow or pied crow. A typical site is between 2 and 20 metres above the ground in a tree or sometimes on a telegraph pole or pylon. Two to seven eggs are laid with three or four being most common. They are incubated for 22 to 23 days, mainly by the female.
The origin of today's major Falco groups—the "typical" hobbies and kestrels, for example, or the peregrine-hierofalcon complex, or the aplomado falcon lineage—can be quite confidently placed from the Miocene-Pliocene boundary through the Zanclean and Piacenzian and just into the Gelasian, that is from 2.4 to 5.3 Mya, when the malar-striped ...
Dead periodical cicadas and nymphal shells pile up at the base of a tree on May 18, 2024, in Charleston, Ill. Trillions of once-hidden baby bugs emerged in huge numbers after years underground.
Rock kestrels have been observed following baboons through grasslands and catching the insect species flushed out. [6] There are also reports of rock kestrels robbing nests for young birds and eating termites on the floor. [7] Their call is a harsh chay-chay-chay, especially when scaring off intruders, unlike the common kestrel's kee-kee-kee.
