Atlantic Puffin ( Fratercula arctica) chick diet and reproductive performance at colonies with high and low capelin ( Mallotus villosus) abundance
We compared nestling diet and growth, breeding phenology, breeding success, and adult mass of Atlantic Puffins (Fratercula arctica) between two seabird colonies adjacent to ocean habitat with presumed high and low capelin (Mallotus villosus) abundance in 19961998. We hypothesized that puffins at th...
