Storm petrels in PortugalYouTube video by A ROCHA Portugalwww.youtube.com

Two likely explanations for these results are: 1) A decline in the Atlantic breeding population of Storm-petrels 2) Changes in their migratory behaviour Understanding whether one - or both – of these explanations is correct is essential to inform conservation efforts for this tiny seabird.

Over this 27-year study in Portugal 6,786 Storm-petrels were captured and released during their migration north, providing valuable insights into these seabirds. This research revealed that the number of Storm-petrels being caught by researchers each hour has fallen by 69% over the study period

Swifts are one of the UK’s most threatened species, declining by 70% over the last 30 years, so this research reinforces why protecting their nesting sites and providing suitable new ones is a vital part of helping the species’ recovery.

Scientists studied 190 different Swifts from 243 nests over 15 years and found that 94% of Swifts reused the same nesting site as in a previous year.

Their comeback is thanks in part to conservation efforts carried out by RSPB nature reserve staff and volunteers to restore their precious lowland heathland habitat.

The UK Dartford Warbler population crashed in the 1960s, leaving only a few pairs in Dorset. The most recent national survey has now revealed the highest ever number of Dartford Warblers recorded on RSPB nature reserves with 264 pairs counted in 2025 – a 44% increase in just five years.

Results indicate that Corncrake conservation would benefit from increasing the proportion of land that has tall early cover vegetation, rather than grassland mowed for silage in August. This management requires special support. This camera survey method could be used for other secretive species.

Until now, little has been known about the behaviour of Corncrake chicks and females because they hide in tall vegetation. Trail cameras were deployed on the Isle of Coll; in grassland managed for silage production and livestock grazing. The cameras successfully captured images of Corncrakes.

Greater policy commitment, investment and research will be needed to turn this potential into a reality and help monitor nature recovery in the UK.

Monitoring experts agreed that all of the data sources were suitable and that their potential is increasing as technologies develop However, technical, analytical, logistical and financial barriers limit creation of monitoring networks that could yield the data needed for landscape-scale indicators

Many conservation projects work at a landscape scale, but we currently lack suitable biodiversity indicators to measure success at this scale. Scientists looked at the potential for seven biodiversity data sources - including drones, acoustics and eDNA - to contribute to indicators.

This research revealed that the movements of Storm-petrels at sea are influenced by predators, other Storm-petrels, wind & oceanographic conditions such as sea temperature & depth. These insights help us to better identify threats and solutions to help safeguard habitats for these tiny seabirds.

Until now, little has been known about the behaviour of European Storm-petrels at sea. This is because these birds weigh just 26g and GPS tags are only now small enough for them to wear safely Scientists tagged 28 Storm-petrels with miniature GPS devices at their breeding colony on Mousa, Shetland

This uphill range shift is important because as the birds move uphill there is a smaller area of suitable habitat available. This research highlights a particular threat of climate change to island endemics.

Scientists used fourteen years of bird data to demonstrate that four species are shifting their ranges uphill. The most significant shift is by the Montserrat Oriole, which is endemic to Montserrat and a priority species for RSPB.

It’s a great example of how genetic science can support essential conservation efforts 🧬 This insight will allow conservationists to take targeted action, protecting unique genetic lineages and helping secure the species’ future 🌍

Research has shown a worrying decline in some of our much-loved garden birds due to a disease called trichomonosis. This is a highly contagious disease and can spread where birds gather in large numbers such as at bird feeders. See our website for the latest guidance: brnw.ch/21x1t4w
