Return to the Isle of Puffins
Atlantic Puffin Fratercula arctica chick growth in relation to food load composition

Abstract
Despite a long-term (1989-2013) reduction in size of fish brought to Atlantic Puffin Fratercula arctica chicks and a parallel increase in numbers of fish in the food loads, there was no evidence of changes in chick growth rates at Hornøya, NE Norway. Recent declines in chick survival and cessation in population growth suggest, however, that environmental conditions have changed to an extent that breeding success is now compromised.
