Gr 10: What is the Effect of Light Pollution on the Migration of North American Birds?
Intro and Abstract
Birds migrate biannually which makes it very important for their living patterns
light pollution is a real problem that affects bird's migration patterns
Study focuses on the effects of light pollution based on temporal and spatial data
Birds face challenges due to light pollution
Artificial light at night (ALAN) disrupts birds and their ecosystem health, increasing harm to their wellbeing.
Light pollution and its negative impacts can increase disorientation and risk of collisions in birds
Discussion
ALAN poses a threat to not just birds but entire ecosystems
The ecosystems that birds rest on could be very damaging if birds were to suffer
urban environments heighten the risks for birds
Urban environments also have less places for food and less resources
Urban environments have more ALAN
Conclusion
ALAN disrupts natural migration; very bad for birds
mitigation strategies involve:
lights out campaigns
reducing unnecessary lighting during migrating periods
focus on ALAN is critical to bird conservation
Methods and Results
Used Jupyter Notebook to generate graphs
Data from Globe at Night Sky brightness using SQM-LE Unihedron meter
Tribute of Light installation in New York captured data from ALAN.
weekly bird abundance from eBird data
ALAN trends from species abundance
Migration behavior change was observed in rural and urban areas
