Dawn singing in the Swiss National Park
As a nice Christmas present, Julia’s first PhD paper was published. She investigated the effects of different environmental variables on the start of dawn singing in six common songbird species in the Swiss National Park. Moon phase, aspect, temperature and road noise had the most consistent effects across species: dawn singing started earlier after brighter and warmer nights, on more east-exposed slopes, and in areas with more road noise.
