Influence of nest burrow microclimate on chick growth in a colonial High-Arctic seabird, the little auk
The growth of seabird chicks is affected by various environmental conditions. Although species nesting in burrows may thereby reduce the effects of environmental conditions, they are still dependent on the nest microclimate. We investigated the influence of nest microclimate on chick growth in the l...

The growth of seabird chicks is affected by various environmental conditions. Although species nesting in burrows may thereby reduce the effects of environmental conditions, they are still dependent on the nest microclimate.
