How Are the Barn Swallow Chicks Doing?
Artificial Light at Night (aka, light pollution) is a global issue that affects all wildlife. Research shows that artificial light impacts birds' ability to navigate, mate and reproduce, and sleep at the appropriate time.

In chicks, artificial light activates cortisol (fight or flight) and glucose (blood sugar), while suppressing melatonin (sleep hormone), which could lead to issues stemming from lack of sleep and altered nutrient allocation. These issues especially effect the metabolic system, which could lead to various metabolic diseases, such as avian diabetes.
