Warming waters are driving key prey species, like mackerel and capelin, further north. This forces gannets to fly longer distances for food, increasing their energy expenditure and decreasing breeding success.

Recent outbreaks of H5N1 have caused mass mortality. Interestingly, some survivors develop a permanent black iris , which serves as a visible marker of their resilience against the virus.

The rapid expansion of offshore wind farms in the North Sea poses a collision risk, particularly for juveniles who tend to forage closer to the coast where these turbines are often situated. The Road to Recovery

), with its striking blue eyes and six-foot wingspan, is one of the most iconic seabirds of the North Atlantic. Known for spectacular plunge-dives from heights of up to 30 meters, these birds are masters of the ocean. However, recent research—including pioneering work by and Collar —reveals that these sentinels of the sea are increasingly under threat from a "silent killer": marine plastic debris. The Danger of Entanglement Interestingly, some survivors develop a permanent black iris

Studies have found that in certain wintering areas, such as off the coast of Mauritania, up to 20.2% of gannets observed were entangled in marine debris.
