Reproduction
Puberty in males and females is the very next year after birth, although the reproduction of birds tend to begin only at the age of two or three years. Sapsan monogamous, pair of saves during the many years. For this species, regardless of lifestyle, are also characterized by attachment to a particular cluster area, which is a few generations of the birds for a long time - for example, on a small island off the coast of Wales, the researchers observed a rocky ledge, where the birds nest regularly at least to 1243. The beginning of breeding season is in April-June, the northern populations, as a rule, begin to reproduce at a later date. Usually, the first place to the next slot arrives male; podzyvaya female, he performs various air pirouette. Prisevshaya a short distance of the female refers to the fact that the couple finally established; ryadyshkom sitting birds can carefully scan each other to clean the feathers of their partner or nibble fingernails. In addition to Togo, in the male courtship feeding often female, fly it caught them passing prey. Taking food from being the top male, female overturns in the air upside down. In the breeding period peregrine very territorial and aggressive towards newcomers. The distance between neighboring nests, usually more than 1 km, even in areas with high population density and is typically 2-6 km. This area includes space and water, birds need to ensure the smooth availability of food in period of reproduction. Within a cluster of a couple can have up to seven seats, suitable for laying eggs, which are used alternately for several seasons.
Sapsan to protect its territory and with the invasion of its ability to attack the offender, even on a larger predator birds, such as an eagle or a crow. When approaching human birds start to show concern at a distance of 200-300 meters from the nest giving alarming voice signals. Closer to first male and then female with a loud shout kruzhat on a person, sometimes for a short time prisazhivayas nearby.
Location of the nest depends on the surrounding landscape, but in any case requires an open space for podleta and the nearby reservoir. In rocky terrain, it is usually arranged in a rocky crevice in the ledge at the top of the slope at an altitude of 20-80 meters from the ground. In tundra preferred the steep banks of ponds or okolovodnym stony outcrops. At the bog moss nest can be located on the tussock on a small hill. In some regions, such as in Australia or in the north-west coast of North America, nests are often located in the hollows of large trees.
