Me and My Mom - Scene 26 Swan and Cygnets Although swans only reach sexual maturity between 4 and 7 years of age, they can form socially monogamous pair bonds from as early as 20 months that last for many years, and in some cases these can last for life. The lifespan of the mute swan is often over 10 years, and sometimes over 20, whereas the black-necked swan survives for less than a decade in captivity. These bonds are maintained year round, even in gregarious and migratory species like the tundra swan, which congregate in large flocks in the wintering grounds. The nest is on the ground near water and about a meter across. ⇦ Back to Scene 25 Return to Me and My Mom Page 4 On to Scene 27 ⇨ |
