BTO-led research highlights that Afro-Palearctic migratory bird species lack consistent protection during their time in Europe.

BTO research uses tracking data to demonstrate that Nightingales breeding in the UK have an unusual degree of migratory connectivity to their non-breeding range in West Africa, with wider implications for both the UK conservation of this fast-declining species and for the conservation of migratory species in general.

Changes to the timing of spring events are some of the most obvious and highly documented responses to climate change. Differences in the response of timing between interacting groups, such as predators and prey, have the potential to leave some ‘mismatched’, meaning predators lack access to resources on which they rely.

The Curlew is Britain’s largest wader; it is also one of its most threatened. Previous BTO research has shown that this is largely due to the number of chicks fledged that are able to survive to reach breeding age. In this case, if we are to help improve the situation for the Curlew, then we need to understand the factors that influence their breeding success.

Good quality information on species’ population trends is essential for successful conservation action. In this paper, the dataset of the BTO/JNCC/RSPB Breeding Bird Survey (BBS) is made publicly available, along with details of how the data can be used to calculate bird population trends. This will help to further inform bird conservation in the UK and beyond. BBS data have been widely used in research over the past three decades, and they have always been available upon request. However, with this publication, over seven million records are made freely and openly available. In this, the BBS becomes one of few structured national recording schemes for birds anywhere in the world which makes the information collected by its volunteers wholly available to anyone who wishes to access it.
