On average, they (urban birds) began their daily activities around 30 minutes before dawn, while forest birds began their day as the sun rose.

I find this difficult to believe. The dawn chorus (which is actually pre-dawn & tends to stop as soon as the sun comes up) is famous both in the wild & in towns, and I have heard it in both situations. When the sun rises, it's already very light.

Maybe German birds are different! :twisted:
