Throughout the year, 11 different species of raptor birds call Winneshiek County their home! You may have seen pairs of brilliant Bald Eagles near the Upper Iowa River, or maybe you’ve heard the Red-Tailed Hawk’s iconic call from overhead. Whether you’re a casual bird-watcher, or a professional ornithologist, how well do you know your raptors?
Raptors are diurnal birds of prey who are grouped together and classified by their shared specialized physical characteristics that allow them to hunt other animals. Some of these characteristics include large wingspans, sharp talons, hooked beaks, and dynamic bodies meant for flying at high speeds. Examples of raptors include hawks, eagles, ospreys, and falcons.
Raptor birds can be found on almost every continent and live in a wide variety of climates. While most raptors are not true migratory birds, some have migration patterns that vary between species. Some migratory raptor species migrate singly, while others migrate in flocks. A few species are even considered to be nomadic and only leave an area when conditions decline, not based on season like migratory birds!
Raptors are all carnivorous but their diets depend on their size and habitat. Their home range sizes depend largely on the availability of food. For example, if prey is abundant near their nest, many raptor species will choose to keep their home range small. If they need to travel to hunt, their home range will be larger. A difference in home range size is not necessarily based on species because there can be differences in home range size between the same species of raptor.
Raptor birds of all species can be threatened by habitat loss and pollution, so conservation efforts aimed to protect these fierce birds are incredibly important.
