Résumé :	In 2005, during a complete survey of the Magpie breeding population in the county of Dithmarschen, 321 territories (i.e. 0.23 territories/km(2) on 1,405 km(2)) were recorded. Magpies breed today in Dithmarschen in the vicinity of farms, detached houses and groups of houses as well as in villages and towns (Heide and Brunsbuttel, about 20,000 and 14,000 inhabitants). In the open countryside, the Magpie has all but disappeared as a breeding bird; it inhabits only about 6% of the total area of the county. The highest breeding densities are in the above mentioned towns (on average 3.5 territories/km(2)). Outside these towns, the breeding density is about 0.1-0.2 territories/km(2). This is the same for the open countryside and the small villages of the coastal lowlands and the sandy hill landscape. On an annual survey site of 60 km(2) in the coastal lowlands, the species declined significantly in the period 2000-2006. The total population of 321 territories in 2005 is only 48% of the size it was in 1990. The discussion on the cause of this decline is limited to one theme, human persecution: a) in the 1980s high numbers were shot, b) in the course of the hunting ban (1990s) Magpies were very probably caught in traps and killed or poisoned.
