Latest Ecological Research Trends

• Ant Biomass vs. Wild Birds/Mammals: According to a report by Newsspace on May 25, 2026, there are at least 20 quintillion (2×10¹⁶) ants on Earth—about 2.5 million per person. Their dry biomass is estimated to exceed the combined total of all wild birds and mammals. This provides a useful metric for gauging the biomass of wild birds, including owls.

• Owl Habitat Status in Korea: There are currently 10 species of the family Strigidae in Korea, 7 of which are designated and protected as Natural Monument No. 324.

• Threats to Eurasian Eagle-Owls: Data from the National Institute of Biological Resources (NIBR) identifies the Eurasian Eagle-Owl (Bubo bubo) as a large resident bird that prefers rocky cliffs and mountainous areas. Habitat fragmentation and loss, primarily due to road construction at forest edges and shrinking forest areas, are cited as the direct causes of their declining population.

Owl Ecology and Habits

• Physical Distinctions: A common rule of thumb in Korea is that owls usually have "ear tufts," whereas most true owls (in Korean categorization) do not. However, it is noted that these classification standards in the Korean language can be subjective and inconsistent.

• Feeding and Storage Habits: Eurasian Eagle-Owls are known to store food. With a wingspan of about 180cm—roughly the height of an adult—they possess some of the strongest talons among birds. They typically hunt prey ranging from insects and small mammals like mice to foxes and young deer, though they rarely attack or harm humans.

• Adaptability: Owls have relatively low activity levels and can adapt to humans fairly easily, which is why there has been significant research abroad regarding their breeding and care.

Conservation Status

• Natural Monument Status: Out of the 10 Strigidae species in Korea, 7 are protected under Natural Monument No. 324.

• Habitat Threats: As per NIBR, the construction of roads near forests and the overall reduction of forest areas are the primary factors fragmenting the habitats of Eurasian Eagle-Owls.

• Endangered Status: The Tawny Owl (Strix aluco lineage) is classified as a Grade II Endangered Wildlife and is protected as Natural Monument No. 324-1. Institutions like the Institute of Ornithology at Kyung Hee University have contributed to these conservation efforts by conducting fundamental research on the taxonomy and ecology of Korean bird species.
