Another year has passed and Superb Owl Sunday is here! In honor of the world's Strigiformes, we want to celebrate their unique adaptations from plumage to talons.
Last year's line up featured a number of species from Northern California like the Northern Spotted Owl, the Great Gray Owl, and the Burrowing Owl. This year we decided to point the spotlight on the world's rarest! Hoo's ready to discover some of the most elusive owls on the planet?
Spectacled Owl (Pulsatrix perspicillata)
With a habitat range nestled in the rain forests south of Mexico to Argentina (and some Caribbean islands), these rare owls prefer to stay within old growth forests, near a body of water. Named after their unique facial plumage, these owls rock their goggles like no other owl. Adding to the mysterious nocturnal sounds of the rainforest, they are referred to as the "Knocking Owl" by locals in Brazil because their calls sound more like a woodpecker knocking on trees.
Watch out! If you're a smaller bird, mammal, crab, frog or insect, you might find yourself being hunted at night. These owls like to swoop down from the foliage above as their prey walk by, blissfully unaware.
Though Spectacled Owls are not considered endangered, their habitat is shrinking due to deforestation and logging. As elusive as they are, they serve as an indicator species, meaning their presence signals a healthy rainforest ecosystem. Protecting the Spectacled Owl goes hand in hand with conserving Central America’s rainforests, just as the Northern Spotted Owl reflects the health of North America's redwood forests.
Northern Hawk-Owl (Surnia ulula)
Despite their name, these daytime predators aren’t hawks at all. Northern Hawk Owls earn their title thanks to their hawk-like hunting style, relying on sharp vision rather than sound to spot prey from nearly half a mile away. Found in the boreal forests of North America, Europe, and Asia, these stealthy hunters perch high in trees, scanning open landscapes. Unlike most owls, they don’t mind the daylight, making them one of the few truly diurnal owls. They prefer nesting in old tree cavities, often repurposing abandoned woodpecker holes.
Spotting one of these feathered phantoms is no easy feat! Thanks to their remote habitat and solitary nature, these owls are one of the rarest owls to see in the wild. Unlike most owls, they don’t migrate regularly, sticking to their northern territories year-round, even in brutal winter conditions. When food is scarce, though, they may make surprise appearances farther south.Their call? A rapid, high-pitched trill that echoes through the forest, but good luck hearing it, these owls are masters of silence, often going undetected even in broad daylight.
Blakiston's Fish Owl (Ketupa blakistoni)
With a wingspan of up to 6 feet, the Blakiston's Fish Owl is one of the largest in the world. They dwell in the dense riverine forests of Russia, Japan, China, and Korea. Considered a symbol of wisdom and mystery in Japanese Ainu culture, these owls are also incredibly elusive, making sightings a rare treat. These owls uniquely feast upon fish and amphibians, patiently watching from riverbanks before plunging in with their massive talons.
Sadly, they are endangered, with fewer than 2,000 individuals left in the wild due to deforestation, overfishing, and human disturbance. Conservation efforts, including habitat protection and artificial nest programs, are crucial to ensuring the survival of these majestic river hunters.
Príncipe Scops-Owl (Otus bikegila)
Recently discovered, these small owls are endemic to Príncipe Island, a small volcanic island off the coast of Central Africa in São Tomé and Príncipe (each island having its own species). Its mottled brown plumage provides them with exceptional camouflage against tree bark. These owls can be distinguished from any other owls on the island with their rapid and repeated "tuu" sounding call.
While its population size is still being studied, it is believed to be highly vulnerable due to deforestation and habitat disturbance. As a newly classified species, it highlights the importance of conservation efforts in preserving Príncipe’s unique biodiversity.
This discovery reminds us that the world still holds hidden species, waiting to be found in some of the most untouched corners of the planet!
Itombwe or Congo-Bay Owl(Phodilus prigoginei)
This little-known barn owl was found in the remote Itombwe and Kabobo highlands of the Democratic Republic of the Congo, is so rarely seen that it was once believed to be extinct. For decades, scientists only knew of this owl from a single specimen collected in 1951, making it one of the great unsolved mysteries of African ornithology. Then, in 2021, researchers finally confirmed its continued existence. Like a ghost of the rainforest, the Itombwe Owl had quietly persisted, hidden from the world.
Little is known about its behavior, but like other bay owls in the region, it’s likely a stealthy nocturnal hunter, preying on small mammals and insects under the thick forest canopy. With deforestation threatening its already tiny range, conservationists are racing to learn more before this rare owl fades back into obscurity. For now, the Itombwe Owl remains one of nature’s best-kept secrets. A living legend of the African night.
Northern Saw-whet Owl (Aegolius acadicus)
The Northern Saw-whet Owl (Aegolius acadicus) may be small, but don’t let its tiny size fool you. This wide-eyed nocturnal hunter is a fierce predator! Measuring only about 7–8 inches tall, these owls are one of the smallest in North America, with a round head, no ear tufts, and big, bright yellow eyes that give them an almost perpetually surprised look. Their name comes from their distinctive call: a repetitive, high-pitched “toot-toot-toot” sound that some say resembles the sound of a saw being sharpened on a whetstone.
While these owls are not rare in the United States, they are rarely seen. Their small size, excellent camouflage, and nocturnal habits make them incredibly difficult to spot. Despite their cute appearance, these owls are fierce hunters, sometimes taking down prey nearly their own size. They even store extra food, often decapitating their catches and stashing them in tree crevices for later meals.
With their adorable yet ferocious demeanor, the Northern Saw-whet Owl is truly one of North America’s most fascinating (and elusive) feathered hunters.
Ferruginous Pygmy-Owl (Glaucidium brasilianum)
These owls may be tiny, but they have a big personality! Measuring just 6–7 inches tall, these fierce little predators are diurnal, making them one of the few owls you might actually spot in broad daylight... if you're lucky. With their rusty-brown plumage, piercing yellow eyes, and "don't mess with me" attitude, they are true feathered firecrackers. They even have a built-in defense mechanism: dark markings on the back of their heads that look like extra eyes, tricking potential predators into thinking they’re always being watched.
Despite their small size, these owls are all business when it comes to hunting. They fearlessly take down prey larger than themselves, including birds, lizards, and small mammals.
If you're in Mexico, Central America, or South America, Ferruginous Pygmy-Owls are pretty common and can be found in forests, savannas, and even backyards. But in the U.S., these little raptors are a rare find. In Texas, they hold on in small numbers, but in Arizona, they’ve become so scarce that conservationists are working hard to protect them. And if you’re in New Mexico? Sorry, they’re locally extinct. You won’t find any there. With ongoing habitat loss threatening their survival in the U.S., conservation efforts are more important than ever to ensure future generations can marvel at these tiny but mighty predators.

As we wrap up another Superb Owl Sunday, we hope you've enjoyed learning about some of the rarest and most fascinating owls across the globe. If you do happen to see one of these rare owls, consider yourself owl-mazingly lucky because a sighting is truly a rare treat!
Just like a Super Bowl-winning team, owls need a strong defense and that means protecting the habitats they call home. Whether it’s preserving old-growth rainforests, maintaining healthy river ecosystems, or restoring desert woodlands, every effort counts in keeping these rare and remarkable birds in the game.
