White amiamoko hungry
1991/11/01 Elhuyar Zientzia Iturria: Elhuyar aldizkaria
German asbestos targets in Schleswig-Holstein are hungry. The long-term cold and drought have considerably reduced the number of insects and worms. On the other hand, there are very few amphibians and frogs in the pools of water, which are dry and full of manure. In addition, although the rat is abundant for two years, in the third there is a shortage.
Most of the amiamokos returned from Africa late because the northern winds hindered the migration of these birds. At the end of May, 15% of the 220 asbestos couples were missing.
In 1989 in the village region of Bergenhus, 20 young people were starved in their nests. Along with the lack of rain, drainage in many commercial use fields was the most negative factor.
Similar factors are occurring this year and researchers consider that the negative effects of droughts are only a consequence of land tenure without water. Bergenhusen birds begin to receive a complementary fish diet.
But this help cannot be maintained in the long run. Kai-Michael Thomsen of the German Federation for Nature Protection says we need more wet fields.
