About Reddish scops owl
The reddish scops owl (Otus rufescens), first described by Thomas Horsfield in 1821, is a small owl species native to the lowland rainforests and swamps of Southeast Asia. Its geographical range includes countries such as Thailand, Malaysia, Indonesia, and Brunei. This species is characterized by its predominantly red-brown plumage, which features a paler face and ear tufts, along with distinctive black spotting on the chest and white spotting on the back and wings. Juveniles exhibit similar patterns but with less pronounced spotting.
Description and Vocalization
Measuring between 15 to 18 cm in length and weighing between 70 to 83 grams, the reddish scops owl is a compact bird. Its vocalization is a notable feature, consisting of a whistling "hooo" sound that is repeated at intervals of 7 to 11 seconds. Interestingly, the calls of this species can be reliably sexed, with males producing a higher-pitched call compared to females.
Habitat and Behavior
The reddish scops owl primarily inhabits lowland forest environments, including dense rainforests and swampy areas. It is a non-migratory species, typically occupying a home range of 1.31 to 2.16 hectares. While its diet is not extensively documented, it is known to consist mainly of arthropods and small vertebrates.
Breeding and Conservation
Nesting for the reddish scops owl occurs within tree cavities. Observations on Java indicate that eggs can be found in March and April, with nestlings present by mid-July. The species is currently evaluated by the IUCN as Near Threatened, with its population believed to be declining. The primary threats identified are habitat loss due to logging and the detrimental impact of capture and sale within the illegal wildlife trade. The reddish scops owl has two recognized subspecies: O. r. malayensis and O. r. rufescens.
