Broad-winged Hawk

Buteo platypterus

A small hawk, common in eastern woodlands in summer. Staying around the edges of forest, Broad-wings are often not very noticeable during the breeding season, but they form spectacular concentrations when they migrate. Almost all individuals leave North America in fall, in a mass exodus to Central and South America, and sometimes thousands can be seen along ridges, coastlines, or lake shores when the wind conditions are right.
Conservation status Early in the 20th century, large numbers were sometimes shot during migration, but with legal protection their numbers now seem healthy.
Family Hawks and Eagles
Habitat Woods, groves. Typically breeds in deciduous forest or mixed coniferous-deciduous forest, often near water and near clearings or edges. Migrants may be seen over any kind of open country, but tend to stop for the night in forest or extensive groves of trees.

Feeding Behavior

Hunts by watching for prey from a perch, usually located along edge of woods or near water. When prey is spotted, the hawk swoops down rapidly to capture the creature in its talons. Occasionally hunts by flying through the woods or along watercourses, actively searching for prey.


Eggs

Usually 2-3, sometimes 1-4. Whitish, usually spotted with brown. Incubation is almost entirely by female, 28-31 days. Male brings food to female during incubation, then he may sit on eggs while she eats. Young: Female remains with young almost constantly for first 1-2 weeks after they hatch; male brings food, and female feeds it to nestlings. Young may climb out of nest onto nearby branches at about 4-5 weeks; can fly at about 5-6 weeks, and soon start learning to hunt.

Diet

Includes small mammals, amphibians, reptiles, birds. Varied diet includes mice, voles, squirrels, other small mammals; toads, frogs, snakes, lizards, young turtles; various small birds; large insects. Sometimes eats crayfish, fish, centipedes, earthworms.


Nesting

Early in breeding season, pairs circle high in the air, calling. In display, one bird may fly high, then dive steeply toward the ground. Nest site is usually in the lower part of a large tree (either deciduous or coniferous), typically 25-40' above ground. Nest (built by both sexes) is a rather small platform of sticks, lined with softer materials such as bark and moss. Leafy green twigs often added during nesting cycle. Often uses pre-existing nest of hawk, crow, or squirrel, adding material to it.

Migration

A long-distance migrant, most going to South America for the winter. Migrates in flocks. Birds from throughout the east travel southwest or south to go around, not across, the Gulf of Mexico.

How climate change could affect this bird's range

In the broadest and most detailed study of its kind, Audubon scientists have used hundreds of thousands of citizen-science observations and sophisticated climate models to predict how birds in the U.S. and Canada will react to climate change.

Broad-winged Hawk

The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season.

More on reading these maps.

Each map is a visual guide to where a particular bird species may find the climate conditions it needs to survive in the future. We call this the bird’s “climatic range.”

The colors indicate the season in which the bird may find suitable conditions— blue for winter, yellow for summer (breeding), and green for where they overlap (indicating their presence year-round).

The darker the shaded area, the more likely it is the bird species will find suitable climate conditions to survive there.

The outline of the approximate current range for each season remains fixed in each frame, allowing you to compare how the range will expand, contract, or shift in the future.

The first frame of the animation shows where the bird can find a suitable climate today (based on data from 2000). The next three frames predict where this bird’s suitable climate may shift in the future—one frame each for 2020, 2050, and 2080.

You can play or pause the animation with the orange button in the lower left, or select an individual frame to study by clicking on its year.
