Summary: Some animals can adapt to climatic change by altering timing of spring migration or emergence and the onset of breeding. In some species this has been shown to cause a mismatch between predators and prey, when phenological changes differ between species. Such a mismatch is thought to contribute to the 40% decline in UK Pied Flycatcher populations observed since 1990. Using national scale data we are investigating spatial variation in caterpillar availability (prey) and bird (predator) breeding parameters in relation to climate and its population consequences.
