31 Relationship between nutritional status and prolactin levels in the Common Eider, a capital incubator
In Common Eider, only females incubate while fasting for 25 days. When their body condition is deteriorated at hatching, females often abandon their ducklings. To therefore investigate how body condition may mediate parental care in eiders, we studied the effect of a change in the duration of incuba...
