Meet Indonesia’s New Owl Species: Otus jolandae

Discovery and Identification

In the lush forested foothills of Lombok, an island just east of Bali, a new species of owl has been discovered. The distinctive “pwok” call of this owl, unique to Lombok, caught the attention of ornithologists George Sangster and Ben King in 2003.

Locals on Lombok were familiar with the bird, known as “burung pok” (literally “pook bird”), a mimicry of its unusual hooting. However, neighboring islands had never reported hearing this call, suggesting the species’ restricted distribution.

Taxonomy and Vocalizations

The researchers’ analysis of the owl’s vocalizations and morphological characteristics revealed that it differed significantly from other known owl species. Its unique call pattern and lack of individual variation in feather patterns indicated that it was a distinct species.

Historical Records and Rediscovery

Interestingly, specimens of this owl were collected in 1896 by Alfred Everett, a British administrator in Borneo. However, it was not until the rediscovery of these specimens and the analysis of their calls that the owl’s true identity was confirmed.

Evolutionary Isolation and Speciation

The researchers hypothesize that the Lombok owl’s ancestors may have been isolated on the island due to a catastrophic volcanic eruption. This isolation allowed the owls to evolve into a unique lineage, distinct from their neighboring island counterparts.

Naming and Conservation

The new species has been named Otus jolandae, in honor of George Sangster’s wife, Jolanda. It is the first bird species known to be endemic to Lombok, highlighting the island’s unique biodiversity.

Scientific Significance

The discovery of Otus jolandae underscores the importance of ongoing research to uncover the hidden diversity of the natural world. It also highlights the vital role of vocalizations in the identification and classification of owl species.

Ecological Relationships and Research Opportunities

Further research is needed to understand the ecological relationships and conservation status of Otus jolandae. Its restricted distribution and unique characteristics make it a valuable subject for studying evolutionary processes and the impact of habitat changes on avian biodiversity.

Additional Information

  • The discovery of Otus jolandae was published in the journal PLoS ONE.
  • The researchers used a combination of field observations, vocal recordings, and genetic analysis to identify the new species.
  • Owls are known for their distinctive hooting calls, which serve as a form of communication and territorial defense.
  • The study of owl vocalizations has been instrumental in uncovering the diversity and evolutionary relationships within the owl family.
  • The conservation of endemic species like Otus jolandae is crucial for maintaining the health and resilience of ecosystems.
