BTO relies heavily on the efforts of thousands of committed and skilled volunteers, who take part in our long-term monitoring schemes. The data they collect generate robust and long-term evidence describing changes in the populations of birds and other wildlife, which in turn prompts further research and conservation action. BTO continually innovates to improve survey design and ease of participation, while broadening our supporter base is a key aim for the future.

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 the...

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. These so-called phenological shifts could...
Survey determines drivers of House Martin breeding success
Latest research based on the House Martin Survey shows that one of the simplest ways to help House Martins is to provide artificial nesting cups.
