The Luzon scops owl (Otus longicornis) is a special type of scops owl that lives only on the island of Luzon in the Philippines. You might also hear it called the Luzon highland scops owl. It's important not to confuse it with the Philippine scops owl, which is a more common owl found in the same area.
The Luzon scops owl is smaller than its lowland cousin. It also prefers to live in higher places, like mountains.

What Does the Luzon Scops Owl Look Like?
The Luzon scops owl is quite small, even for a scops owl found in the Philippines. It grows to be about 18 to 19 centimeters (7 to 7.5 inches) long. Its wings are about 13.6 to 15.3 centimeters (5.3 to 6 inches) long.
This owl has big, bright yellow eyes. Its beak is small and thin. Its legs are covered with feathers about halfway down. It has long, sharp claws, just like other birds of prey.
Unique Features
Like other scops owls, this species has long ear tufts. These tufts look like little horns on its head. Its feathers are mostly dark brown and reddish-brown. You can see dark stripes across many of its feathers.
Its chest, collar, and face have white spots. These spots make it look like it has white eyebrows. The feathers on its throat, head, and ear tufts are dark brown or reddish-brown with black tips.
We don't know much about how much these owls weigh. But a few measured owls weighed between 82 and 93 grams (about 2.9 to 3.3 ounces).
How Scientists Classified This Owl
The Luzon scops owl is a unique species. This means it doesn't have any subspecies. For a while, people thought these owls were part of other species. Some thought they were Otus spilocephalus. Others thought they were O. scops.
But in 1978, a scientist named Joe T. Marshall studied them closely. He looked at their body features and listened to their calls. He found that they were different enough to be their own species. That's how they got the name Otus longicornis.
Owl Family Tree
Genetically, the Luzon scops owl is most closely related to two other owls. These are the Mindanao scops owl (O. mirus) and the Mindoro scops owl (O. mindorensis). They are similar because they all like to live in high-altitude places.
Studies show that Philippine scops owls that live in highlands are different from those that live in lowlands. For example, the Philippine scops owl and the Giant scops owl prefer lower areas.
Where the Luzon Scops Owl Lives
The Luzon scops owl lives in rainforests, mountain forests, and pine forests. They usually live at heights from 350 to 1,800 meters (about 1,150 to 5,900 feet). Sometimes, they can even be found as high as 2,200 meters (about 7,200 feet).
Even though their habitat covers a large part of Luzon, these owls are not very common. They live in scattered areas that match their favorite highland homes. They have been seen in northern Luzon provinces. These include Ilocos Norte, Benguet, Cagayan, Isabela, and Nueva Ecija. They have also been seen closer to Manila in Bulacan and Quezon. Sometimes, they are found as far south as Camarines Norte and Camarines Sur.
Luzon Scops Owl Behavior
From the few times people have seen them, Luzon scops owls seem to stay in the same place. They don't move around much during the year. Like many owls, they are active at night.
Vocalizations
Male Luzon scops owls often call at night. Their call is a single whistle that gets lower in pitch. Each whistle is separated by about 3 to 5 seconds of quiet. Their call sounds a bit like the Eurasian scops owl. However, many other scops owl species also have a single whistle call.
Diet
We don't know much about what these owls eat. But scientists looked inside the stomachs of a few owls. They found that these owls mostly eat insects. This means they are invertivores.
Reproduction and Life Cycle
Information about how these owls reproduce is very limited. Chicks have been seen born in May. They have soft, light grey down feathers. The owls build their nests in tree holes. A mother owl usually lays 2 to 3 eggs in each nest.
It is thought that adult Luzon scops owls start breeding when they are one year old. They likely have one group of chicks each year.
Protecting the Luzon Scops Owl
As of 2016, the IUCN Red List says the Luzon scops owl is a "near threatened" species. This means it could become threatened in the future. Activities like logging, mining, and farming are causing deforestation in Luzon. These activities threaten many species that live only in this area.
The Luzon scops owl is often found at higher altitudes. Because of this, it's not officially listed as "threatened" by the IUCN. However, these human activities still affect them. The fact that they are rarely seen at lower altitudes might mean they are becoming rare there. This could be due to human disturbance.
It is very important to protect the special places where the Luzon scops owl lives. This also helps other endangered birds. Places like Mount Pulag National Park already protect species that depend on highlands. The Philippine government is also working to create more protected areas. They do this through the National Integrated Protected Area System (NIPAS).
We also need more information about this bird's habitat and population. We don't know how many Luzon scops owls there are. We also don't know much about how their numbers are changing. But it is very likely that their population is decreasing. Scientists recommend doing more surveys to count the owls. They also suggest regularly checking how much habitat is being lost. This will help improve conservation plans for this unique owl.
