How many eggs does an average bald eagle lay in a lifetime? The average Bald Eagle clutch size is just under 2 eggs / clutch (1.9). If we assume that a female eagle begins nesting at age 5, and lives until she is 25, she will have 20 years of egg-laying. There is no evidence that a healthy eagle reduces egg-laying as she gets older. So 2 eggs/year x 20 years = 40 eggs in her lifetime. â PN
A clutch of 3â6 eggs is laid from September to November (depending on latitude) and are pale green spotted with various shades of brown. The eggs are normally covered when the incubating female leaves the nest. Incubation is 18â19 days and the young are usually fledged by around 45 days. Both sexes rear the young.ied crows are generally encountered in pairs or small groups, although an abundant source of food may bring large numbers of birds. The species behaves in a similar manner to the hooded and carrion crows. In Dakar, birds have been observed mobbing passing ospreys and snake eagles but avoiding black kites.
