Research published in British Wildlife by a team led by the BTO provides new possibilities for sound identification to be used as a non-invasive survey method.
Strengthening the evidence base for temperature-mediated phenological asynchrony and its impacts
The earlier arrival of spring, measured by plants flowering, insects emerging, and the timing of egg laying and migrants arriving in birds, is one of the most obvious impacts of climate change on t

Phenological mismatch between breeding birds and their surveyors and implications for estimating population trends
Several studies in recent decades, including those led by BTO, have demonstrated that many birds are migrating or breeding earlier as the climate changes.
