True or False: After leaving the care of their parents, raptors gain upwards of 25% body mass and 10% greater wingspan.

The statement is false because, after leaving the care of their parents, raptors do not typically gain upwards of 25% body mass or an additional 10% in wingspan. Once raptors fledge and become independent, they are often at a size that is indicative of their species' adult form. While growth may still occur, it usually does not reach such significant percentages after parental care ends. These percentages suggest a level of growth that is not characteristic of most raptor species, as their primary growth phase occurs while they are still under the parents' care, focusing on developing flight skills and hunting abilities rather than substantial increases in physical characteristics.

Different species may vary in their growth patterns, and several factors, including nutrition and environmental conditions, influence growth rates. Therefore, the notion that raptors achieve these specific increases in body mass and wingspan post-fledging does not hold true for the majority of raptor species.
