Bald

Knowing this, The female bald eagle is 35 to 37 inchesThe male bald eagle has a body length from 30 to 34 inch

Bald eagles weigh from ten to fourteen pounds. So how am I suppose to find out the wingspan from this information? Please someone explain how to do this in algebric form.

1. Without more information, you can't. Birds of similar sizes can have quite different wingspans. For instance, a 34" waved albatross has a 90 inch wingspan, while a goose the same length (but greater weight) has only about a 56 inch wingspan. A bald eagle the same size is about half way in between (~77 inches). (and the males range down to 6.6 pounds, btw) Albatrosses are gliders with medium wing loading; geese have heavy wing loading. You could make some assumptions about wing loading (which can vary by a factor of 10) and calculate a wing area, but that won't tell you wingspan unless you know the aspect ratio. Eagles have broad wings rather than long wings (low aspect ratio); albatrosses are the opposite with long narrow wings (high aspect ration).
