Ecologists have discovered that the food hoards pygmy owls collect in nest-boxes (‘freezers’) for winter rot due to high precipitation caused by heavy autumn rains and if the hoarding has been initiated early in the autumn. The results of the study show that climate change may impair predators’ foraging and thus decrease local overwinter survival.
