Thanks Lennart , this is the sixt year I'am following this pair of white storks. Problem is that the female every year is much earlier back than the male and mate with a strange male . So for the fourth year in a row it will be given problems if her regular male with metal ring 9396 returns on the nest .But every year male 9396 wins the battle .This male with plastic ring DEW 7X400 is born on 12 km distance from Angeren in Germany (Kranenburg) ,and is a strange male again. I guess it will become again on a fight when 9396 is returning back from Africa . (See other galerys from white storks PADDENPOEL ANGEREN) grt. Jos.
