BTO work on climate change can be divided into three main areas:
- Documenting the impacts of climate change on biodiversity
- Developing and using approaches for predicting future impacts of climate change to identify the most vulnerable species and habitats
- Improving the evidence base to inform how conservation needs to adapt to climate change
Although much of our work has a UK bird focus, we also work internationally and on other taxa.

Measuring the success of climate change adaptation and mitigation in terrestrial ecosystems
Population responses of bird populations to climate change on two continents vary with species' ecological traits but not with direction of change in climate suitability
Population growth rates affected by climatic variables
Research by BTO and Natural England, suggests that climate change has had a detectable impact on a sizeable proportion of England’s avifauna over the last 50 years.
Assessing BTO impact
BTO has a strong reputation for delivering quality science, but does it have an impact? An independent expert panel decides.

Declining population trends of European mountain birds
Mountain areas often hold special species communities, and they are high on the list of conservation concern. Global warming and changes in human land use, such as grazing pressure and afforestation,...
Caterpillars and caterpillar-eating birds: out of synch in space and time?
The increasing temperatures associated with a changing climate may disrupt ecological systems, including by affecting the timing of key events. If events within different trophic levels are...
What's Under Your Feet?
A new study, supported by EDF Energy and BTO, has looked into soil invertebrate communities in the UK using large-scale citizen science data from schools.
Does climate change bring us invasive species?
Non-native species are becoming a more common sight, but is this linked to the changing climate? A new BTO study investigates whether it's possible to predict which non-native species are likely...
Dodging the blades: gulls and wind farms
Initial findings suggest that Lesser Black-backed Gulls in north-west England fly within wind farms, but may avoid wind turbines once there.
Take part in BBS - counting for conservation
The Breeding Bird Survey is the main scheme for monitoring the population changes of the UK’s common and widespread breeding birds.
Does the early bird catch the caterpillar?
Recently published research led by the British Trust for Ornithology (BTO) sheds new light on the impact that climate change has had on common and widespread songbirds across the UK.
Climate change will change bird communities
With climate change a continuing pressure on birds, this new study discovered the effects it may have on existing and future populations.
Protected sites are assigned based on population statistics for vulnerable and endangered species. This new study using WeBS data shows that changes in population size can affect local abundance, and...
A New Approach to Modelling the Relationship Between Annual Population Abundance Indices and Weather Data
Weather has often been associated with fluctuations in population sizes of species; however, it can be difficult to estimate the effects satisfactorily because population size is naturally measured...
