About 60-70% of young osprey and most other hawks perish in their first year primarily due to starvation, although collisions, electrocutions, hunting, and other hazards also befall them. Young eagles and hawks have to learn to hunt for themselves and it is a steep learning curve. Many fail to develop their hunting skills quickly enough to survive. Once they get to full maturity, the odds improve, but there . 90% seems accurate.
