Owls come in all shapes and sizes, from the tiny elf owl to the large Eurasian eagle-owl. But some of the most adorable owls are the miniature owl species. Miniature owls, also known as mini owls or pocket owls, are a group of the smallest owl species in terms of length and weight. Their small stature gives them a cute and cuddly appearance, endearing them to owl enthusiasts. But don’t let their tiny size fool you – these little owls are fierce nocturnal hunters. So what exactly are miniature owls called? Let’s take a closer look at these petite raptors.
What Qualifies as a Miniature Owl Species?
There is no definitive weight or length threshold that officially qualifies an owl as a miniature or mini owl. However, the term generally refers to owl species that are on the very small end of the size spectrum. Some sources define miniature owls as those with an average adult length of 6 to 12 inches and weight around 2 to 5 ounces. By comparison, large owl species like the Eurasian eagle-owl can reach lengths of up to 27 inches and weights exceeding 9 pounds.
To put it in perspective, here are the approximate dimensions of some of the smallest owl species:
| Owl Species | Length | Wingspan | Weight |
|---|---|---|---|
| Elf Owl | 5-6 inches | 12-14 inches | 1.5-2 ounces |
| Pygmy Owl | 6-7 inches | 13-15 inches | 2-3 ounces |
| Long-whiskered Owlet | 5-6 inches | 12-14 inches | 1.5-2.5 ounces |
| Saw-whet Owl | 6-7 inches | 16-18 inches | 2-3 ounces |
So while there are no hard cutoffs for miniature owl status, their tiny proportions compared to larger owl relatives earn them the “mini” label.
Common Miniature Owl Species
There are at least 15 different owl species around the world that could be considered miniature. Some of the most common and popular mini owl species include:
Elf Owl
Native to the southwestern United States, Mexico and Central America, the elf owl is the smallest owl species in the world. Adults reach just 5-6 inches in length with a wingspan around 12-14 inches. Their weight averages 1.5-2 ounces. That’s about the size of a sparrow! These tiny owls get their name from their petite stature. With their large yellow eyes and round heads, they do resemble fanciful elves. Elf owls nest in cavities in cacti or trees and hunt for insects at night using their excellent hearing.
Pygmy Owl
The pygmy owl is found across much of Central and South America. There are also two pygmy owl species native to southern Asia. They are slightly larger than elf owls, averaging 6-7 inches long with a 13-15 inch wingspan. Weights range from 2-3 ounces. Though small, pygmy owls are feisty and will aggressively defend their territory. They hunt small birds, mammals and insects at night or near dawn and dusk.
Northern Saw-whet Owl
The saw-whet owl inhabits forested areas of North America. They are one of the most common miniature owls, named for their distinctive saw-whetting call. Adults average 6-7 inches long with a 16-18 inch wingspan and weigh just 2-3 ounces. Saw-whet owls have bold white facial markings and hunt small mammals like mice, voles and shrews. They nest in tree cavities or old woodpecker holes.
Long-whiskered Owlet
This adorable mini owl is found in forest habitats of Asia. True to its name, the long-whiskered owlet has prominent black feather tufts on its face that resemble long whiskers. It averages about 5-6 inches long with a 12-14 inch wingspan and weighs a mere 1.5-2.5 ounces. The owlet feasts on insects like moths and beetles that it catches midair at night or plucks from leaves.
Little Owl
While not as diminutive as the pygmy and elf owls, the little owl is still on the smaller side at 7-9 inches long and a 20-24 inch wingspan. Native to Europe and Asia, little owls weigh 4-8 ounces. They occupy open countrysides where they hunt for insects, small mammals, reptiles and more. Little owls are recognizable by their round, flat-topped heads and skittish behavior.
Unique Adaptations
Being pint-sized comes with challenges for miniature owls when competing with larger species for food and habitat. But mini owls have some special adaptations that allow them to thrive:
-**Excellent hearing**- An owl’s amazing hearing helps it locate prey in darkness. Miniature owls like the saw-whet owl have asymmetrical ears that amplify sound and aid in pinpointing prey.
-**Speed and agility**- Smaller and lighter bodies allow miniature owls to maneuver swiftly when chasing prey or escaping predators. They have rapid reflexes and can swiftly change directions midair.
-**Camouflage**- Plumage colored and patterned to blend into bark or leaves helps miniature owls hide from predators and sneak up on prey.
-**Fierce hunting skills**- Don’t underestimate these tiny raptors! Miniature owls have sharp talons and hooked beaks for snatching and tearing prey.
-**Cavity nesting**- Mini owls seek out cavities in cacti, trees or rock crevices for nesting. These protected spots keep eggs and chicks safe.
-**Daytime roosting**- Small size allows miniature owls to discreetly roost in foliage during daytime, hidden from larger diurnal raptors.

Threats Facing Miniature Owls
While their petite size gives them some advantages, it also makes miniature owls vulnerable to a range of threats:
-**Habitat loss**- Deforestation, development, agriculture, wildfires and other habitat destruction pressures miniature owl populations. Their small ranges shrink.
-**Predators**- Larger raptors, snakes, and small carnivorous mammals prey more easily on mini owls and their eggs/chicks. Domestic cats also pose risks.
-**Environmental toxins**- Pesticides, heavy metals, and other toxins accumulate in the small bodies of mini owls, reducing reproductive success.
-**Climate change**- Hotter temperatures and drought may reduce insect prey populations relied on by some mini owls like the Northern Saw-whet Owl.
-**Vehicle collisions**- Their habit of flying low across roads at night puts mini owls at high risk of being hit by cars.
-**Illegal pet trade**- Smugglers capture mini owls like pygmy owls and long-whiskered owlets to sell in the illegal exotic pet trade.
-**Natural challenges**- Harsh weather, diseases, parasites and limited food resources also threaten miniature owl survival. Their tiny bodies are vulnerable.
Conservation Status
The conservation status of the world’s miniature owls varies:
| Owl Species | Conservation Status |
|---|---|
| Elf Owl | Least Concern |
| Pygmy Owl | Least Concern |
| Northern Saw-whet Owl | Least Concern |
| Long-whiskered Owlet | Near Threatened |
| Little Owl | Least Concern |
Species like the elf owl and Northern saw-whet owl remain widespread and are of Least Concern. But others like the long-whiskered owlet face steeper declines from deforestation and the pet trade, putting them at greater risk. Ongoing conservation efforts aim to preserve the unique habitats mini owls rely on.

Catching sight of one of these tiny feathered creatures is a magical experience. Here are some tips to spot them in the wild:
-**Research habitat**- Learn where species you hope to see occur and their preferred terrain like deserts or coniferous forest.
-**Focus on dawn and dusk**- Mini owls are most active at dawn and dusk when hunting. Stake out areas before sunrise or after sunset.
-**Listen for calls**- Many mini owls have surprisingly loud voices. Stop and listen for them hooting to each other.
-**Check cavities**- Scan trees, cacti, and rock crevices where mini owls may be roosting during the daytime.
