- Wingspan: 20-24 inches
- Status: Stable, some regional declines
- Diet: Insects (grasshoppers, beetles), small mammals (voles), small birds
- Behavior: Hovering flight while hunting, territorial, partially migratory
- Habitat: Grasslands, farmlands, suburban fringes, parklands
The American kestrel, North America’s smallest falcon, is mesmerizing in its bright color and acrobatic flight. Males sport dramatic blue wings and rusty-colored tail, but the females have more muted brown hues with black barreling. Often seen hovering in fields in the Allegan State Game Area and other locations, kestrels hunt with military-like precision, preying on grasshoppers, voles, and little songbirds.
Thus, their existence within agricultural areas strengthens ecosystems by slowing down pest infestations, gaining them appreciation from farmers. Unlike peregrines, kestrels are less migratory, with most staying on in southern Michigan during milder winters, but some migrate south. Their nature is characterized by a characteristic hovering flight, whereby they flap wings rapidly to examine the ground beneath.
At breeding, kestrels nest in tree holes or artificial boxes and lay 4-5 eggs that incubate for 28 days. Yet, the loss of habitats due to urbanization and the conversion of farmland threatens their nesting places, and conservationists urge nest box schemes. Thus, the American kestrel’s flexibility and contribution to the environment render it a beloved icon of Michigan’s landscape, which enthralls birders with its colorful beauty.
3. Merlin – The Forest Falcon:

In migration season, merlins converge on spots such as Whitefish Point, where their quick, low passes entrance bird enthusiasts.
As a result, their tendency to inhabit remote environments, like the Upper Peninsula’s coniferous woods or beach dunes, creates the challenge of spotting them a challenge worth the effort. Merlins are extremely migratory, breeding in Michigan and wintering in Central and South America, and nest in coniferous trees, laying 4-6 eggs. They are characterized by aggressive territoriality, especially during breeding, when they aggressively protect nesting territories.
Unlike peregrines, merlins do not readily accept urban environments, confining themselves to more natural terrains where they hunt with fierce determination. But forest degradation through logging threatens to imperil the species. Thus, merlins continue to be an elusive yet fascinating presence in Michigan, captivating those fortunate enough to catch their energetic flight.
4. Gyrfalcon – The Arctic Wanderer:

The hobby, a swift and agile falcon found in Europe, Africa, and Asia, is an unintentional vagrant in Michigan, with sightings so infrequent they are the stuff of birder legend. Their long, pointed wings and dark, slate-gray feathers create a unique silhouette, especially when executing their acrobatic. In Michigan, hobbies may be found in open woods, fields, or coastal marshes such as those along Sleeping Bear Dunes, particularly during migration periods when storms may sweep them from the Atlantic.
They employ a combination of speed and agility to hunt, frequently snatching insects out of the air with a quick skill that approaches the ferocity of the merlin. Hobbies are migratory, wintering in Africa, and their migratory social behavior, occasionally hunting in loose packs, contributes to their charm.
Consequently, the potential presence of the hobby in Michigan, though incredibly unlikely, adds an injection of international flair to the state’s diversity of falcons, enthralling birders at the possibility of catching sight of this nimble acrobat.
“He gives strength to the weary and increases the power of the weak… they will soar on wings like eagles.” – Isaiah 40:29-31, Bible
Habitats and Distribution – Seasonal Movements To Urban Jungles:
Falcons in Michigan traverse a range of habitats, from vibrant urban centers to peaceful wilderness. In response, this section delves into their living environments, adaptive tactics, and seasonal migrations throughout the state.
Urban Jungles: Falcons in Cities
Peregrine falcons have converted Michigan’s urban centers into their playgrounds. Detroit, Grand Rapids, and Lansing skyscrapers serve as contemporary cliffs, with nest boxes working as safe breeding sites. In addition, the high availability of urban prey such as pigeons drives their success, which reveals the victory of conservation efforts that merge wildlife with urban life.
Rural Retreats: Countryside Falcons
American kestrels and merlins dominate Michigan’s rural landscapes. Kestrels ride telephone lines along farmlands, their eyes searching for small prey such as mice or insects. Meanwhile, merlins terrorize the Upper Peninsula’s woods, building nests amidst coniferous canopies. Agricultural sprawl erodes habitat, however, threatening these havens and the need for effective conservation. It is therefore imperative to maintain grasslands and woods in order to preserve rural populations of falcons.
Coastal and Wetland Wonders:
Michigan’s Great Lakes coastlines and wetlands attract falcons, especially in migration. Peregrines and merlins prey along coast dunes, and kestrels cruise neighboring marshes. Hotspots such as the Shiawassee National Wildlife Refuge and Sleeping Bear Dunes are ideal for observation. As such, these areas are important migratory stopover points.
Seasonal Movements:
Falcon distribution cycles with the seasons. Peregrines and merlins have spectacular southbound migrations every fall, following coastlines of Great Lakes to the warmth. Kestrels will often remain through winter in southern Michigan, suffering less severe winter weather.
Challenges Facing Falcons:
Though they are persistent, falcons are faced with daunting challenges. Thus, this section examines the dangers threatening their numbers and how to curtail them.
Urbanization and timber cutting destroy areas where falcons live. Kestrels battle with declining roosting territories as agricultural areas transform into suburbia. Just like merlins, habitat pressures from lumbering in coniferous regions pose a similar threat. So, maintaining space and using nesting boxes are fundamental to reversing those losses.
Climate change interferes with falcon migration and prey abundance. Warmer winters can shift kestrel residency patterns, while severe storms pummel peregrine nesting colonies. In addition, reduced insect populations affect kestrel diets.
Peregrine nesting on buildings can alarm property managers into nest removals. Similarly, farmers can misidentify kestrels as pests, even though they are useful. Thus, education campaigns and outreach promote coexistence, resolving conflicts by means of informed dialogue.
Although DDT is in the past, contemporary pollutants are dangerous. For instance, rodenticides have the potential to poison falcons through tainted prey. Wetland water pollution also interferes with migratory stopovers. Therefore, promoting cleaner environments and regulations is essential to the survival of falcons.
Final Thoughts:
Falcons of Michigan, ranging from the shocking peregrine to the cryptic hobby, are a living reminder of nature’s tenacity and mankind’s commitment to sharing. The raptors that inhabit Michigan’s state, resident birds such as the kestrel and rare vagrants such as the Amur falcon, awe with their speed, beauty, and environmental importance.
Michigan’s diverse landscapes—cityscapes, countryside views, and lakeshore retreats—provide refuge, and conservation creativity, amateur science, and public enthusiasm ensure their permanence.
As you wander Michigan’s landscapes, look up for a brief glimpse of these winged masters, be it a mundane merlin or a legendary red-footed falcon. Take the plunge through birding, volunteering, or activism, and assist in chiseling the falcon’s story into Michigan’s future.
