Falcons are birds of prey, but separate from eagles, kites, and hawks. Unlike these other raptors, falcons kill their prey with their beaks rather than their talons. They are also usually faster, and have longer and more slender wings compared to hawks. There are 7 species of falcons that regularly visit the United States, but in this article we will look at the 4 species of falcons in Utah.
4 Falcons in Utah
The 4 species of falcons most commonly found in Utah are the American Kestrel, Merlin, Peregrine Falcon and Prairie Falcon.
Let’s take a look at each species.
1. American Kestrel
- Scientific name: Falco tinnunculus
- Length: 8.7-12.2 in
- Weight: 2.8-5.8 oz
- Wingspan: 20.1-24.0 in
The American Kestrel is North America’s smallest falcon, larger than a robin, but slightly smaller than a crow. But don’t let their small stature fool you. Kestrels are fierce predators that can take down other birds as big or bigger than they are, such as Northern Flickers.
They primarily feed on insects and invertebrates like grasshoppers, beetles, cicadas, dragonflies, moths and spiders. They also eat mice and other small rodents, bats, lizards, frogs and songbirds.
These tiny falcons have small heads and unique coloring of rusty browns and bluish grays. Both sexes have black barring on their back, and two black stripes on the face. Females are mostly rusty colored, while males have bluish-gray on their head and wings.
Look for them in the summer when they are most active. They often perch on fence posts and telephone wires, especially around farmland. Kestrels can position their body into the wind and hover in place, scanning the ground below.
The American Kestrel can be found throughout Utah year-round.
2. Merlin
- Scientific name: Falco columbarius
- Length: 9.4-11.8 in
- Weight: 5.6-8.5 oz
- Wingspan: 20.9-26.8 in
Merlins are another small falcon found in Utah. You’ll have a chance to see them during the winter, after they have migrated south from their summer breeding grounds in Canada.
Their primary food source is other birds, such as house sparrows, dickcissels, sandpipers and other shorebirds. Merlins are experts at the high speed attack, zooming across the ground horizontally or even chasing their prey from below, forcing them higher and higher unt
