Swallows in Thuringia: Early breeding season battles weather problems!
Find out why Thuringia's swallow population will decline in 2025 and how NABU is promoting local protective measures.

Swallows in Thuringia: Early breeding season battles weather problems!
Spring in Thuringia - a time that stands for walks in nature and the reawakening of the animal world. But this year, the return of barn swallows and house martins, those iconic birds, is facing unexpected difficulties. Loud Thuringia24 The swallows returned significantly later than usual this year. Aspect of the breeding season, which normally begins around May 1st, was heavily influenced by extreme weather on the way back to Thuringia.
Nature, always helpful, donated a lot of snow and rain to the Alpine region this year, which made the journey of these birds more difficult. Tino Sauer, the swallow representative at NABU Thuringia, notes that the first broods have an average delay of two weeks. Enthusiastic nature lovers can find the Schmidt family in Eichelborn, where new artificial nests are provided for house martins. There the family was presented with the first plaque for a swallow-friendly house in 2025, part of a nationwide campaign that recognizes the commitment to swallow protection.
Campaign for swallow protection – a success story
In total, over the last 15 years, over 2,000 households in Thuringia have been honored with an award for their commitment to swallow protection. A typical site with around 100 buildings could house up to 30 breeding pairs, showing how valuable these birds are to ecological balance. This information comes from the report by the German Nature Conservation Association (NABU), which provides information about the current status of swallow populations.
Another interesting aspect is the decline in swallow populations in Erfurt, Weimar and other parts of Thuringia - a worrying development that is linked to the extreme weather conditions. The return of the swallows from their winter quarters was made more difficult by both the late winter and rainy days, which ultimately led to a dramatic decline in the number of breeding pairs, as NABU also stated in its last communication.
Climate change and its consequences
The changes in bird populations in Germany are not only due to local weather conditions. A comprehensive study of the Federal Agency for Nature Conservation underlines the far-reaching effects of climate change on biological diversity in Germany. Drawing on over 1,000 literature sources, the report analyzes how climate change is affecting the habitats and reproductive patterns of many species.
Climate change poses a serious threat, not just to swallows, but to many native species. It is all the more important that we as a society raise our awareness of nature conservation and become active. Measures to support swallows, such as providing nesting sites and maintaining swallow nests on houses, are simple but significant steps in the right direction.
Anyone interested is invited to take an active part in protecting swallows. Especially in this challenging time for nature, it is more important than ever to make a change - for the swallows and our environment.
