Getting help with the kids slows down aging in female birds

Seychelles warblers live and breed in family groups on the tiny island of Cousin. In each group, a dominant female and male reproduce. When helpers assist the with incubation and feeding of chicks, the dominant female breeder's age more slowly and live longer, a study by biologists from the University of Groningen and colleagues from the Universities of East Anglia, Leeds, Sheffield, and Wageningen shows. The results, which are published in the journal Nature Communications on 21 March, indicate how cooperative breeding – which also occurs in other species, including humans – can increase life span. The Seychelles warbler lives on Cousin Island in the Indian Ocean, measuring just 500 by 700 meters. Some fifty years ago, only a handful of birds survived. Read more here >>>
