Light Pollution in Swiss Cities Impacts Bird Breeding Patterns

Research reveals urban great tits experience disrupted breeding patterns due to artificial lighting, raising concerns about biodiversity in Swiss cities.

Key Takeaways

Great tits in Swiss cities have fewer young in nesting boxes compared to those in forests
Urban great tits are more restless at night and warm their eggs less consistently
Light pollution affects birds' navigation abilities, especially during foggy conditions

By The Numbers

Higher

Hatching rate in forest nesting boxes compared to urban areas
