Migration Advancement: Storks move to their winter dwellings sooner this season - Migratory pattern shift: Storks increasingly spending winter in the specified location
The Stork Centre in Bornheim has reported an early migration of storks in Rhineland-Palatinate, a phenomenon linked to climate change effects in the region. Director Jessica Lehmann attributes the early migration to the persistent drought, which has caused food scarcity.
This year, young storks started their journey at the end of July, while some adult storks departed up to two weeks earlier than usual. The autumn migration has begun earlier than in previous years, with many adult storks moving to irrigated agricultural land or landfills in search of food.
The breeding season in 2022 was somewhat more successful than in 2021, with many nests having several young. However, the survival rate of young storks remains low, with about 70% dying in the first year. This year, fungal infections in wet nests led to numerous deaths of young storks.
Storks are being regularly sighted in the Palatinate Forest, especially when foraging. However, a geographical shift is of particular interest, with declines in established colony areas like the Palatinate and populations increasing in the Eifel, HunsrΓΌck, and West Palatinate.
Storks are known to react flexibly to environmental conditions. When food is scarce, they often choose to leave early rather than wait for better conditions. The drought in Rhineland-Palatinate has made food scarce, forcing many adult storks to move.
The identified cause for the earlier migration of storks in Rhineland-Palatinate in 2022 is linked to climate change effects observed in that region. However, the specific detailed cause or region within Rhineland-Palatinate directly associated with this phenomenon is not explicitly stated in the available search results.
More cases of storks dying from plastic have been registered in care stations due to the shift of adult storks to irrigated agricultural land or landfills. This underscores the need for continued efforts to reduce plastic waste, not just for the sake of storks but for all wildlife.
Despite the challenges, the survival of the stork population in Rhineland-Palatinate remains resilient. Around 85% of the storks have already set off for their winter quarters. The food situation at the beginning of the season was good, with many nests having several young.
However, only around 7 to 9% of young storks reach an age where they can breed themselves. This means that the population relies heavily on successful breeding seasons and the survival of young birds. The Stork Centre continues to monitor the situation closely and works towards ensuring the survival and well-being of these majestic birds.
