Egg Neglect in the Procellariiformes: Reproductive Adaptations in the Fork-Tailed Storm-Petrel

摘要: The eggs of many procellariiform birds may still hatch even though temporarily abandoned during the incubation period. Distant foraging and long periods, characteristic these birds, increase probability that storms or undependable food resources will delay an individual's returning to relieve its incubating partner. Consequently, tolerance chilling by embryo has evolved a greater degree in Procellariiformes than other orders. This paper reports incidence egg neglect Fork-tailed Storm-Petrel (Oceanodroma furcata), discusses adaptive significance costs Procellariiformes.
