Answer 1

The average lifespan for most raptors is one to two years, though it is likely to be longer for some larger species. The oldest known free-living accipitrid lived to age 38. In captivity, large eagles and vultures have lived up to 60 years. (Snyder, 2001; Thiollay, 1994)

The mortality rate of accipitrid nestlings (during the period between hatching and fledging) is between 20 and 40 percent. The vast majority of this mortality is due to food shortage and/or siblicide, though predation can also be a significant source of mortality. The period immediately following fledging is the time of highest mortality during a raptor’s life. This is the time when the young bird is still mastering the arts of flying and hunting. Estimates of mortality for the interval between fledging and acquisition of adult plumage range as high as 90 percent for some species. Likely sources of mortality during this period include starvation, predation, disease and accidents. (Thiollay, 1994)

Estimates of annual adult mortality for accipitrids range from 65 to 90 percent. Generally, annual survival is higher in larger species and lower in smaller species. Sources of mortality for accipitrids have historically included deliberate shootings, poisoning and trapping. More recently, these sources of mortality have declined. However, Accipitrids still die from electrocution (power lines), collisions with vehicles and wind turbines, and poisoning from pesticides or from poisoned carcasses intended for other predators. (Thiollay, 1994)

Answer 2

well I have an unbrella cockatoo and they are said to live 30 to 40 years, an Eagle also can live up to 47 years, the rest I guess it depends on their survival skills.
