Balancing moult, migration, and breeding in a long‐lived partially migrant raptor
Journal of Avian Biology, Volume 2026, Issue 2, March 2026.Moult, breeding, and migration are the three major life‐history events in the annual cycle of birds. All are energetically demanding processes that rarely overlap. In large raptors such as the Egyptian vulture Neophron percnopterus, completing a full moult may take more than one year, requiring birds to balance this process with other life‐cycle events.

Nesting behaviour influences species-specific gas exchange across avian eggshells [PDF]
, 2014 Carefully controlled gas exchange across the eggshell is essential for the development of the avian embryo. Water vapour conductance (GH2O) across the shell, typically measured as mass loss during incubation, has been demonstrated to optimally ensure the
