Falcons are among the most captivating birds of prey in Tennessee, known for their incredible speed and agility. These sleek hunters can be found throughout the state, soaring over fields, rivers, and even urban areas, where they’ve adapted to life among tall buildings that mimic the cliffs they prefer. Falcons play an important role in maintaining the balance of local ecosystems, keeping populations of smaller birds and rodents in check.
Tennessee is home to several falcon species, including the Peregrine falcon, known for being the fastest bird in the world, capable of reaching speeds over 200 miles per hour during a dive. Another local favorite is the American kestrel, a smaller but equally impressive falcon that can often be seen perched on telephone wires, scanning for prey.
These birds are not just admired for their hunting prowess; they also serve as a symbol of strength and resilience. After facing threats like habitat loss and pesticide exposure in the past, many falcon populations have made a remarkable recovery thanks to conservation efforts. For anyone who enjoys watching wildlife, spotting a falcon in Tennessee is always a special experience, a reminder of the wild beauty that thrives across the state’s diverse landscapes.
Peregrine Falcon
- Scientific name: Falco peregrinus
- Life span: 8-15 years
- Size: 14-19 inches (36-48 cm)
- Weight: 1.1-3.3 pounds (500-1500 grams)
- Wingspan: 3-4 feet (90-120 cm)
- Status: Least Concern
- State status: Breeding and rare
- Migration pattern: Leaves Tennessee by late fall to winter
The Peregrine Falcon is one of the most widespread raptors globally, found on every continent except Antarctica. In North America, it can be seen from the Arctic tundra to the deserts of Mexico, including across Tennessee. Peregrines prefer habitats with open landscapes like coastlines, mountains, and river valleys, but they have adapted well to urban areas, where they nest on tall buildings.
These birds are known for their striking appearance. They have a slate-blue or gray back, a white or buff underside, and distinctive dark bars across their belly. Their heads are marked by a black cap and a prominent black “moustache” that stands out against their pale cheeks. When seen in flight, their long, pointed wings and powerful, rapid wingbeats make them easy to identify.
Peregrine Falcons are renowned for their incredible speed, especially during their characteristic high-speed dives, or stoops, as they hunt in mid-air. They’ve recently made a huge recovery in my home country of Denmark, and the newest number suggests 20 breeding pairs, compared to 0 in 2001.
Peregrine Falcons are known for their preference for high, open nesting sites, which provide an expansive view of their surroundings. Historically, they nested on steep cliffs or bluffs, often near rivers or coastlines, where their eggs would be protected from predators. In more recent years, these adaptable birds have embraced urban environments, nesting on skyscrapers, bridges, and towers, mimicking the cliffs they once relied on.
The female typically lays 3-4 eggs in a scrape—a shallow depression she makes in gravel or soil. Both parents take part in incubation, though the female does most of it while the male hunts. After about a month, the eggs hatch, and the young remain in the nest for around 6 weeks before fledging. The sight of young peregrines taking their first flight from high perches is a striking moment that draws bird watchers to cities and natural cliffs alike.
The diet of a Peregrine Falcon is centered around its extraordinary hunting skills, especially when it comes to catching birds in mid-flight. These falcons primarily hunt medium-sized birds like pigeons, ducks, and songbirds, though their diet can vary based on their habitat. They are renowned for their spectacular hunting technique, the “stoop,” where they dive at speeds of over 200 miles per hour to strike prey with tremendous force. This precision allows them to catch agile birds in midair, leaving little chance for escape.
Urban-dwelling Peregrines often target city-dwelling birds such as pigeons or starlings, taking advantage of abundant food sources. On the coasts, they may pursue seabirds, while in more rural or natural settings, they target a mix of migratory and resident birds. This ability to adapt their diet according to their environment has helped the Peregrine Falcon to survive in various regions across Tennessee and beyond.
The conservation story of the Peregrine Falcon is a testament to the power of coordinated recovery efforts. By the mid-20th century, the species faced near extinction in North America due to widespread use of the pesticide DDT, which caused eggshells to thin and break. By the 1970s, almost all breeding pairs had vanished from the eastern United States, including Tennessee.
In response, biologists launched a large-scale recovery program that included banning DDT, raising chicks in captivity, and reintroducing them to the wild through a process called “hacking.” These efforts, led by organizations like the Peregrine Fund, proved successful, and populations began to rebound in the 1980s. In Tennessee, they have returned to nest on both natural cliffs and urban structures, becoming a symbol of conservation success.
The species was removed from the federal Endangered Species list in 1999, though it still remains a protected species and a subject of monitoring to ensure their populations continue to thrive.
American Kestrel
- Scientific name: Falco sparverius
- Life span: 5-10 years
- Size: 8-12 inches (20-30 cm)
- Weight: 2.8-5.8 ounces (80-164 grams)
- Wingspan: 20-24 inches (51-61 cm)
- Status: Least Concern
- State status: Breeding and common
- Migration pattern: Migrates south in fall; some remain year-round
The American Kestrel, often called a sparrow hawk, is a colourful and common falcon across the Americas, including Tennessee. Its range extends from Canada down through Central and South America. It favours open areas like fields, meadows, and farmlands, making it a familiar sight perched on wires or fence posts.
This small falcon is visually striking, with males sporting slate-blue wings and a rusty-orange back and tail, while females are more uniformly rust-coloured with dark barring. Both sexes have two dark vertical stripes on each side of their face, giving them a distinctive, masked look. The American Kestrel’s wings are relatively long and pointed, while its tail is often fanned when hovering or perched.
This bird’s size and beautiful plumage make it easily recognizable, even from a distance. Despite its small stature, the American Kestrel displays a bold presence wherever it is found.
American Kestrels are cavity nesters, meaning they seek out natural holes in trees, cliffs, or artificial nest boxes to lay their eggs. They don’t build their own nests, so they rely on finding old woodpecker holes, natural tree cavities, or even spaces in buildings and barns.
In Tennessee, kestrels are known to use nest boxes provided by conservation groups, which have helped boost their nesting success. During the breeding season, the female usually lays 4-5 eggs, which she incubates for about 30 days while the male brings her food. After the eggs hatch, both parents feed the young, and the chicks grow quickly.
Within about a month, the fledglings are ready to leave the nest, but they stay nearby as they learn to hunt. Nesting kestrels are often seen perched on telephone poles or wires near their chosen sites, keeping a sharp lookout for potential threats to their young.
The American Kestrel’s diet is diverse, allowing it to thrive in a variety of environments, including those across Tennessee. Its diet primarily consists of insects like grasshoppers, crickets, and beetles, which it catches with agility and precision. During warmer months, these small falcons can be seen hunting insects over fields and meadows, often hovering in place before diving down to snatch their prey.
However, they are opportunistic hunters and will adjust their diet based on availability. When insects become scarce, especially in colder months, they shift to catching small mammals such as mice and voles, as well as small birds. Their ability to adapt their diet seasonally helps them maintain a steady food supply throughout the year. Kestrels hunt both from perches, where they scan for movement on the ground, and through hovering flights, which make them a unique sight in open landscapes.
While the American Kestrel is still considered common in much of its range, including Tennessee, it has faced declines in certain areas, raising concerns among conservationists. Habitat loss, particularly the removal of old trees that provide essential nesting cavities, has been a significant challenge for this species.
Pesticide use, which reduces their prey availability, and increased predation from larger raptors like hawks and owls, have also impacted their populations. To counter these trends, conservation efforts have focused on installing nest boxes in suitable habitats to provide more nesting opportunities. In Tennessee, these efforts have shown promise, helping kestrels find secure nesting sites in both rural and suburban areas.
Additionally, monitoring programs have been established to track population changes and ensure that this vibrant falcon remains a common sight in the state. Public awareness campaigns emphasize the importance of maintaining open spaces and suitable hunting grounds, which are crucial for the kestrel’s long-term survival.
Merlin
- Scientific name: Falco columbarius
- Life span: 5-10 years
- Size: 9-11 inches (23-28 cm)
- Weight: 5-7 ounces (140-198 grams)
- Wingspan: 20-26 inches (51-66 cm)
- Status: Least Concern
- State status: Migratory and rare
- Migration pattern: Leaves Tennessee in late fall for southern wintering.
The Merlin is a compact and energetic falcon with a circumpolar distribution. It breeds in the northern forests and open areas of North America, Europe, and Asia, and migrates southward during the winter. In Tennessee, the Merlin is most often seen during migration periods or as a winter visitor. Unlike some of its relatives, it tends to prefer open landscapes, coastal areas, and wetlands, where it can be spotted perched in trees or on utility poles.
The Merlin’s appearance is characterized by a dark, streaky plumage. Males typically have a slate-gray back with lighter underparts streaked with dark brown, while females and juveniles have a more brownish coloration. Both sexes have a faint facial stripe, though it is less pronounced than that of other falcons.
Their wings are broad and their flight is rapid and direct, giving them an intense presence in the sky. The Merlin’s compact body and steady wingbeats make it distinguishable in flight.
The Merlin’s nesting habits differ from many other falcons, as they often reuse old nests built by other bird species, such as crows or hawks. They are not known for building their own nests, which is a characteristic that sets them apart. During the breeding season, which typically takes place in northern forests, they prefer dense stands of coniferous or mixed woodlands. In some cases, they may even nest on the ground in open, tundra-like areas.
They usually select nests high in trees, providing a good vantage point and some protection from predators. The female lays 4-5 eggs, which are incubated for around a month, primarily by the female while the male supplies food. After the chicks hatch, both parents work diligently to feed them until they fledge, which occurs after about another month. Although not a breeder in Tennessee, the Merlin’s nesting behaviour is an important aspect of understanding this small but fierce falcon.
The Merlin is a nimble hunter, known for its quick and relentless pursuit of prey, mainly small birds. Unlike some falcons that use high-speed dives, Merlins often rely on speed and agility during horizontal chases, surprising flocks of small birds like sparrows or starlings. They also catch insects on the wing, adding to their diet during warmer months when insects are more abundant.
During winter, when they are present in Tennessee, their diet consists largely of small birds that remain active in the area, as well as any insects they might still find. This falcon’s hunting style is characterized by direct, rapid flights, often following the contours of the land as they pursue their prey. The Merlin’s ability to adapt to a variety of prey types allows it to survive in diverse habitats, from woodlands to open fields, making it a
The conservation history of the Merlin is one of gradual recovery and stability. While never facing the extreme declines of species like the Peregrine Falcon, Merlins did experience some population challenges in the mid-20th century, largely due to habitat loss and pesticide use. However, they have benefited from the broader regulations that followed, including restrictions on harmful pesticides like DDT.
Unlike some other raptors, Merlins have shown a degree of resilience, even expanding their range southward during migration and winter months, including into Tennessee. Conservation efforts have focused on preserving the natural habitats where they breed and winter. Protection of forested areas in their breeding range, as well as maintaining healthy populations of their prey, has helped Merlins maintain stable populations.
In Tennessee, they are considered a winter visitor, and efforts to conserve habitats along migration routes help ensure these swift falcons continue to grace the skies. As a species that has adapted well to changing landscapes, the Merlin serves as an example of how targeted conservation measures can make a difference.
