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.

Immature gannets are significantly more likely to be affected, with entanglement rates nearly 30 times higher than those of adults. This creates a "bottleneck" that threatens the future growth of the population. A Multi-Pronged Ecological Threat
