However, we would like to apologise for combining two separate facts here. It was actually the nest that was 1.5km away from the nearest stream where they would normally deposit sacs. But the sacs were deposited in a nearby water trough instead.

High resolution tracking projects such as these can help us understand how seabirds use the sea

And importantly, predict how development- or climate-driven changes to ocean processes may alter seabird habitat use

Use of tidal mixing fronts varied between birds based on individual space use and the habitats and ocean features they encountered

Birds whose foraging ranges overlapped most with tidal fronts were more likely to switch to foraging near these features

To understand the context of individual birds’ responses to fronts, authors used tracking data to cluster birds by foraging area and test how environmental context shapes their response to fronts

Bird movements were then categorised as either resting, travelling or foraging

Tidal mixing fronts are often highly productive areas, where nutrient enrichment and prey aggregations create important foraging hotspots for marine predators

Scientists used GPS loggers to track 144 Kittiwakes from neighbouring North Sea colonies close to the Flamborough Front

This research highlights the need to balance conservation action with community livelihoods

By involving local communities in management decisions and co-developing interventions, conservation programmes can reduce the potential for conflict in the landscape

Using these key drivers, authors then mapped water, livestock and Saiga distributions

They identified >60 areas where conflict was likely to occur

These maps could be used to target conflict reduction action and even potentially avoid it

Results revealed a few key drivers of conflict:
- Crop damage
- Competition for water and grazing
- Concern over livestock catching diseases from Saiga

They also found conflict was highest during the calving period in spring and in winter, when demand for hay and water is high

Western Kazakhstan hosts over half of the world’s Saiga, intensifying conflict between local communities and the species

To identify and map the causes of this conflict, researchers conducted >100 interviews with local herders
