General Size Differences
Hawks and eagles are both majestic birds of prey that exhibit significant differences in size. While both belong to the Accipitridae family, eagles are generally larger than hawks. Eagles typically have a stockier and more robust build compared to hawks, which are relatively slimmer. However, it’s important to note that there are various species of hawks and eagles, and the specific size can vary within each species.
Wingspan
One of the key distinguishing features between hawks and eagles is their wingspan. Eagles generally have much larger wingspans than hawks. The wingspan of an eagle can range from six to eight feet or even more, depending on the species. In contrast, hawks typically have a wingspan ranging from two to four feet. The longer wingspan of eagles allows them to soar effortlessly for prolonged periods, utilizing rising air currents.
Length
In addition to wingspan, the overall length of hawks and eagles also varies. Eagles tend to be longer in length compared to hawks. On average, eagles measure around two to three feet, excluding the length of their tails. Hawks, on the other hand, are generally slightly smaller, ranging from one to two feet in length, excluding the tail.
Weight
Another notable difference between hawks and eagles is their weight. Eagles are significantly heavier than hawks due to their larger body size. Depending on the species, eagles can weigh anywhere between six to fifteen pounds or even more for some species like the Harpy Eagle. On the contrary, hawks are relatively lighter, with weights ranging from one to four pounds. These weight differences reflect the diverse hunting strategies and ecological requirements of these magnificent birds.
Physical Appearance
Body Shape
When observing hawks and eagles, their body shapes provide valuable clues for identification. Eagles possess a bulkier and more muscular body structure, which aids them in hunting larger prey and soaring at higher altitudes.
