Will Peach’s career – at both BTO and RSPB - consistently delivers lasting conservation impact. Will’s research has guided practical conservation action to improve the futures for some of the UK’s most threatened birds, including Song Thrushes, Cirl Buntings and Turtle Doves.
Caption: Will’s work has tested what agri-environment management is needed to reverse declines of several species, including Cirl Buntings.

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
Figure from the paper: Long-term decline in the hourly capture rate of European Storm-petrels in south-west Portugal. Fitted lines are model  predictions (dashed lines = ±95% CI) from models without environmental variables (blue) and with environmental variables
(orange). Predictions were based on median values for time of night 01:00, and Julian day 165 in both models. Model predictions with environmental variables (2006–2017) were also based on median values for wind speed 3.2 kph, wind direction 180°, sea surface temperature 14.35 °C and a moon luminosity of 0.

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.
Caption: Chicks become independent of the mother at only 12-14 days old, when they are still covered by black down. This older chick is about 18 days old and is living independently. Its brown feathers are appearing, but it will not be able to fly until it is 42 days old. Corncrake chicks are vulnerable to silage mowing throughout their flightless period.

The scavenging behaviour of birds such as skuas and giant petrels increases viral transmission risk through close contact with carcasses and other scavengers. These highly pelagic birds may therefore serve both as reservoirs and vectors for disease transmission across the Southern Ocean and beyond.
