Energetic demands during incubation and chick rearing in a uniparental and a biparental shorebird breeding in the High Arctic
Rearing of young has long been considered the energetically most demanding phase of the avian breeding cycle. Arctic-breeding shorebirds expend large amounts of energy during breeding. Because they are too small to carry sufficient stores to sit out the incubation period, they regularly interrupt in...
