Order: Falconiformes The hawks, eagles, falcons, and allies make up a group known as the diurnal raptors, because they are active during the day. Members of this group typically use their acute vision to catch live vertebrate prey with their strong feet and toes.
They vary from medium-sized to large birds and most have an upright posture and strong, short, hooked bills. The New World vultures not closely related to the Old World vultures were once classified with the herons and allies, but they have provisionally been grouped with the diurnal raptors on the basis of recent genetic studies. Members of the order Falconiformes in Washington fall into three families:.
Family: Accipitridae Although this is a large and varied family, its members share many similarities. They are all diurnal hunters and, for the most part, use their sharp vision to locate prey, which they capture with strong feet.
Many members of this family are migratory, and they often concentrate along major migration corridors. These migration corridors often follow ridgelines, where the birds ride updrafts to facilitate their journey south. Like other birds of prey, female hawks et al. Most members of this family are monogamous, and many form long-term pair bonds. Females generally incubate the eggs and brood the young, with some assistance from the male.
The male brings food to the nest. Once the young no longer need to be brooded, both parents bring food. Extended parental care is the norm for this group, as it takes a relatively long time for young to learn to hunt.

Those that breed in Canada and the northern United States generally migrate for the winter to warmer locations in the southern United States, Central America, and South America.
Due to their diet, they nest near water, along rivers, lakes, wetlands, and coastal marshes. They frequently nest on telephone poles, pilings, channel markers, and other man-made structures in or near the water.
Adults are sometimes preyed upon by bald eagles and great horned owls , while eggs and chicks are sometimes taken by snakes and raccoons. Fish represent about 99 percent of their diet. Ospreys are very successful hunters, catching fish on at least one-quarter or more of their dives. They circle over shallow waters to locate fish below the surface. Once they locate a fish, they hover briefly and then dive into the water feet-first, sometimes becoming completely submerged.
Ospreys have several different calls, usually accompanied by a specific posture or aerial display, which they use for alarm, courtship, begging, and defending their nests. Osprey have long migrations to breeding areas in the Pacific Northwest, Canada, and the north Atlantic coast of the United States.
Their breeding months range from January through May. Osprey pairs are generally monogamous and often mate for life. The male selects a nesting site in a dead tree, on a cliff, or on a man-made structure in or near the water. The pair collects sticks and other nesting materials together, but the female generally arranges the nest, which is large and bulky.
Pairs will often use the same nest in following years. The female lays between two to four eggs over several days, then the male and female both incubate the eggs. Chicks that hatch first generally do better than those that hatch later, as they compete for food. The bottom of the bird's foot appears as though it could use some lotion, but what you are seeing are backward-facing barbs.
These barbs make the Osprey's feet extra rough, which they need to be to hold on to a slippery fish. Another thing to notice is that two of the Osprey's toes face forward, while two face backward.
They can change the position of their toes from this configuration to having three forward and one back. This, too, helps these birds get a better grip on prey. Anyone who has tried to hold a slippery fish knows how easy it would be to drop one! Life is hard for any predator.
They must use a lot of energy when catching prey. If Osprey dropped many of the fish they caught, they would waste a lot of energy for nothing. These two adaptations help them hold on to their dinner as they fly to a secure perch to eat. Like so many other species of wildlife in the s and s, Osprey populations suffered negative effects from the widespread use of the pesticide DDT.
Today, their populations are doing much better and Osprey seem to be holding their own. However, there are still many risks these beautiful birds of prey must face in their daily lives. In some parts of the world, people shoot Osprey because they see them as competitors for the same food source. Contamination in rivers and lakes, loss of habitat, and even electrocution are some of the challenges facing Osprey in a modern world.
Though Ospreys mainly eat live fish of a wide variety of species, the types of prey they might catch are quite diverse.
Snakes, birds, frogs, reptiles, mammals, crustaceans, and other invertebrates can all fall prey to the deft, sharp talons of an Osprey. When searching for their next meal, Ospreys usually fly low and slowly over the water, or even hover briefly over a spot that looks promising. All the while, their keen yellow eyes are on the lookout for movement just beneath the surface of the water.
If they don't spot a fish that way, they may resort to more clever tactics.
