inventory development

Hear-constant in Central Europe around 1950 still approx. 430 breeding's pairs, then it came into the 1950er and 1960er years to a dramatic population break-down and an acute inventory endangerment. Due to the substantial load by Pestizide, in addition, by catch and illegal firing by pigeon breeders as well as by egg theft was the moving falcon of becoming extinct threatens. Only by the prohibition of Pestiziden such as DDT and by comprehensive protection and Auswilderungsprogramme the existence of the moving falcon could recover again gradually. In the year 1989 the breeding occurrence became estimated 430 pairs in Central Europe -Turn of the century already proceeded one from 700 breeding's pairs.

appearance

the moving falcon is nearly as large as bus pool of broadcasting corporations and at its long to recognize pointed wings as well as its relatively short tail in the flight quite well. Its fast, strong wing impacts are salient.

habitat

the moving falcon hunts predominantly in the free air space and is therefore in nearly all landscape forms to observe - preferably however over open area and at waters with bird wealth. It became meanwhile in some cities the culture follower. It breeds then in high buildingslike Kirchengiebeln, old factories, o. A. and hunts on the innumerable city pigeons of the respective cities (z. B. in Goettingen). Otherwise the moving falcon prefers steep rock slopes as breeding place, more rarely also abandoned refuges of other grab birds or crow nests.

hunt way

the hunt way of the moving falcon is extremely spectacularly: He hunts excluding flying birds in the free air space - either from a Ansitzwarte from or from high circle flight. The booty spectrum hands laughter sea gull from numerous kinds of small bird to medium sized kinds as ring-airworthiness directive-practices and and is different depending upon local offer. To its preferentialBooty counts however the house pigeon. The partners of a pair hunt in the winter occasionally together in so-called. Company hunt.

Is often assumed that the moving falcon can achieve competitionless top speed of 340 km/h or more with its dives, reliable radar measurements have so far however only top speedfrom 140 km/h result in [1]. These measurements do not exclude however under any circumstances the mentioned, substantially higher speeds in the dive.

reproduction

the partners of a pair of moving falcons usually a life remains long together. The breeding duration amounts to 33 days with a clutch of eggs size of three to fourEggs. The moving falcon reaches a maximum age of 17 years in free nature and of 21 years in shank.

The moving falcon was bird of the yearly 1971.
