Abstract
Hatching asychrony creates a size and age hierarchy within the nest. This hierarchy has big short-term consequences for the last hatched chick. However there is little known about the long-term consequences. Negative impacts during the nesting stage has been found in all species featured in this thesis. It is expected that adult juniors are: smaller, have a lower life expectancy and have lower dominance ranks, all resulting in lower fitness compared to seniors. In some species persistent effects are found, but in the biggest/longest studies on seabirds the results were conflicting. One of the studies found some effect on fitness but two did not. More research is needed to find out if this lack of long-term effects is universal for all bird species.
