As of today, peak season now, through ~July 15. Earth Exhibit tracks the live conditions and flags it the moment it is on.
In some years, multi-year population increases of small tundra rodents lead to conspicuous rises in Arctic fox (Vulpes lagopus) breeding success and visible foraging activity across lowland wetlands such as Þjórsárver.
Observers can see more foxes, frequent den visits, and increased daytime foraging during spring and early summer of boom years.
The timing and intensity vary year to year with winter snow, vegetation productivity, and regional rodent cycles.
