A falcon streaking past at highway speed on a fence post outside Amarillo and a falcon perched on a downtown Houston skyscraper ledge might belong to two completely different species, yet most drivers never look up long enough to tell. Texas hosts five types of falcons that hunt across its coastlines, prairies, deserts, and cities, and each one has carved out its own niche in a state large enough to hold arctic tundra migrants and tropical grassland specialists at the same time. There are about five species of falcons making Texas their home range: Peregrine Falcon, American Kestrel, Merlin, Prairie Falcon, and Aplomado Falcon.
These birds share a few traits that set them apart from hawks and eagles. Unlike other raptors, falcons kill their prey with their beaks rather than their talons. According to Texas Parks and Wildlife, falcons are specially adapted to high hunting flight speeds, with excellent eyesight, strong claws, and persistence. The sections below break down where each species lives, what it eats, and how to tell it apart from its Texas neighbors.
| Species | Relative Size | Conservation Status | Where to Find It | Best Season |
|---|---|---|---|---|
| American Kestrel | Smallest, roughly robin to Blue Jay-sized | Common, though numbers are declining | Statewide, common in DFW and rural fence lines | Year-round |
| Merlin | Slightly larger and stockier than a Kestrel | Stable | Statewide except the far northeast corner | Winter and migration |
| Peregrine Falcon | Crow-sized, powerful build | Recovered from historic decline | Coastal cities, bridges, and open country statewide | Migration and winter |
| Northern Aplomado Falcon | Long-legged, medium-sized | Federally and state endangered | South Texas coastal prairie, Rio Grande Valley | Year-round, non-migratory |
| Prairie Falcon | Similar size to a Peregrine, paler plumage | Rare to uncommon | West Texas canyons and cliffs | Fall through winter |
American Kestrel
The American kestrel (Falco sparverius) is the falcon most Texans have already seen without realizing it. It is North America’s smallest falcon, but don’t let that fool you. Kestrels are fierce predators that can take down other birds as big or bigger than they are, such as Northern Flickers.
In North Texas, this species is a familiar backyard sight. The most common falcon in the Dallas/Fort Worth Metroplex is the American Kestrel, a small, Blue Jay-sized raptor frequently seen perched on utility wires overlooking open fields and vacant lots. These birds are year-round residents in North Texas and breed readily in urban areas, using cavities and man-made structures near good hunting grounds.
Coloring makes this species easy to pick out from every other falcon in the state. Males have a rusty colored back and lighter rusty underside, with blue on their wings and the top of the head plus black markings near the eye, while females are lighter overall with rusty orange barring on the wings, back, and tail. That patch of slate-blue is worth a closer look if you enjoy tracking blue-hued birds in Texas. American Kestrels eat small creatures including insects, reptiles, amphibians, birds, and rodents, which makes them regular visitors over fields packed with grassland insects in Texas.
Despite their adaptability, kestrels are not immune to habitat pressure. The species is comfortable around people and commonly uses human-made nest boxes to raise young, but numbers have been steadily declining, so any help we can give them is beneficial. Putting up a properly sized nest box is one of the simplest ways a Texas landowner can support this species.
Merlin
The Merlin (Falco columbarius) is a compact, fast-flying falcon built for chasing down other birds in open country. Slightly stockier and broader through the chest than a Kestrel, it relies on the same slim, pointed-wing design that separates all falcons from bulkier hawks. Falcons differ from hawks in their smaller size, slim build, and narrow pointed wings built for speed and agility, while hawks have broader wings and a bulkier build suited to power rather than speed.
Merlins are present across nearly the entire state for much of the year. Merlins live all over Texas year-round, except for a small area in the northeast corner of the state. They favor open grasslands, coastal flats, and farmland edges where smaller birds gather in flocks, including areas frequented by dove species common across Texas.
Like other Texas falcons, Merlins are opportunistic hunters. Falcons are not picky eaters and tend to dispatch anything alive, generally feeding on smaller birds, reptiles, and bats. On the insect side, Merlins will readily take large flying prey such as dragonflies and larger moths when birds are scarce, making open areas rich with moth species found in Texas attractive hunting grounds during migration.
Pro Tip: Merlins fly with quick, powerful wingbeats and rarely hover, unlike the American Kestrel, which frequently hangs in place over a field while scanning for prey. Wingbeat style is often the fastest way to separate the two species at a distance.
Peregrine Falcon
The peregrine falcon (Falco peregrinus) is the fastest animal on the planet in a dive, and Texas sits along one of its major migration corridors. Nothing on the planet is faster than a Peregrine Falcon when it’s diving for prey, and these raptors have been recorded at speeds up to 200 mph.
This species is not a picky eater. Peregrine Falcons primarily eat other birds, and at least 450 different types of birds have been documented as their prey; they take almost anything they can catch, including ducks, gulls, pigeons, and songbirds, and have even been observed killing individuals as small as a hummingbird and as large as a Sandhill Crane, along with hunting bats when birds aren’t available. Along the Texas coast, that broad diet often includes species found among the state’s water birds native to Texas, and inland populations will just as readily target backyard visitors, including yellow-colored songbirds seen across Texas.
Peregrines shift their range with the seasons. Peregrine falcons migrate to most of the northern half of East Texas in the warmer months and the far southern half in the winter. Many have also learned to treat cities like cliff faces. Peregrine falcons adapt amidst artificial structures, using bridges and skyscrapers as nesting ledges in a way that highlights their flexibility as aerial predators.
The species’ recovery is one of the better conservation stories among Texas raptors. Falcons became deathly ill or developed unusually fragile egg shells from DDT, a synthetic pesticide sprayed extensively in the 1940s through the late 1960s. DDT’s use in the United States was banned in the early 1970s, and Peregrine Falcon numbers rebounded enough that other endangered raptor programs in Texas now point to the species as the recovery benchmark to match.
Northern Aplomado Falcon
The Northern Aplomado Falcon (Falco femoralis septentrionalis) is Texas’s rarest falcon and its most dramatic conservation success story in progress. The species was placed on the federal endangered species list in 1986, primarily because of loss of the grassland prairie habitat where it hunts. In Texas, most of the native coastal prairie has been lost due to fire suppression, invasive brush encroachment, and conversion of grassland to agricultural fields, housing, and other uses.
Reintroduction efforts run by the Peregrine Fund, Texas Parks and Wildlife, and the U.S. Fish and Wildlife Service have slowly rebuilt a wild population. Broader restoration work in Texas released 997 birds into the wild at 27 sites, including many private ranches, from 1993 to 2013. As of June 2019, scientists had banded the 500th Aplomado falcon in Texas as part of ongoing monitoring at coastal sites. At Mustang Island State Park, one breeding pair occupies one of 67 artificial nest structures maintained along the Texas coast.
Important Note: The Northern Aplomado Falcon remains federally and state listed as endangered, and its recovery depends heavily on cooperation from private landowners who control most of its former range. Program leaders have said “our ultimate goal is to see this species removed from the endangered species list like the Peregrine Falcon.”
The Aplomado’s hunting style fits its long-legged, long-tailed build. This falcon uses speed and maneuverability in flight, plus the ability to move rapidly on the ground in open habitats, to capture its favorite prey of birds such as pigeons and doves and larger insects, supplementing that diet with small mammals and reptiles, especially lizards. That reptile-heavy diet overlaps with the state’s lizard species found in Texas and smaller gecko species in Texas that shelter in the same coastal brush.
Curiously, this species never builds from scratch. Aplomado Falcons never build their own nests; they take over unoccupied nests of other species such as crows, jays, hawks, ravens, or magpies. The best place to see one in the United States is the Rio Grande Valley of South Texas, where nest boxes placed around the valley, along with power-lines and fence posts, are good spots to check.
Prairie Falcon
The Prairie Falcon (Falco mexicanus) is the state’s most elusive regular species, largely confined to the arid canyons and high plains of West Texas. In migration and winter these falcons are rare to uncommon in west Texas, becoming casual further east.
Documented breeding records for this species inside Texas are thin. Breeding records are scarce, with historical reports noting young ready to fly on March 4 and a nest found on June 3. Little breeding habitat description exists for Texas Prairie Falcons, though a breeding record at Hueco Tanks in El Paso County suggests cliffs may be important, as they are across the species’ broader range.
Prairie Falcons hunt over open ground, taking ground squirrels, small mammals, songbirds, and large insects wherever they turn up in numbers. In the grasshopper- and cricket-rich grasslands of West Texas, that means overlap with the same fields that support the region’s cricket species in Texas and various beetle species in Texas. Pale, sandy-brown plumage helps this falcon blend into the caliche cliffs and canyon walls it favors for nesting and roosting.
Texas birders looking for the state’s full falcon lineup have the best odds during the colder months. Winter is when falcon diversity peaks in Texas, as migrant falcons move south where prey is more abundant, and November through March is the best time to see them, especially along the coast. Pair a coastal winter trip with a West Texas canyon visit, and spotting all five resident species in a single season becomes a realistic goal rather than a lifetime list item.
