The Torotoroka scops owl (Otus rutilus madagascariensis) is a subspecies of owl in the family Strigidae. It is endemic to the western parts of Madagascar, and was previously regarded as its own species. However, O. madagascariensis and the rainforest scops owl Otus rutilus have now been re-lumped following Fuchs et al. (2007) as the Madagascar scops owl or Malagasy scops owl. [1] Therefore this taxon now becomes a subspecies, Otus rutilus madagascariensis. [2]

Description

It is very similar to the rainforest scops owl Otus rutilus, and possibly indistinguishable from it. [3] The two were formerly identified by different habitat preferences, with Torotoroka preferring drier habitats and Rainforest preferring wetter forests. Some small plumage and vocal differences were noted but minimal genetic divergence was found. Therefore, Clements has merged the two species. [4]

Distribution and habitat

This taxon is endemic to the western parts of Madagascar. [5]

Its natural habitat is subtropical or tropical dry forests, as well as man-made habitats such as parks, up to 2000m above sea level. [5]

Taxonomy

The Torotoroka scops owl, the Mayotte scops owl Otus mayottensis, the Pemba scops owl Otus pembaensis and the rainforest scops owl Otus rutilus have all previously been lumped as one species. The taxonomy is in a state of flux but recent genetic studies have placed the Pemba scops owl closer to the clade containing the African scops owl Otus sengalensis, while the Mayotte scops owl is clearly separate from the remaining two. The status of the rainforest and Torotoroka scops owls as separate species is debatable as there is very little genetic distance between the two taxa [6] [7] and subsequent studies have suggested that the plumage differences between O. rutilus and O. madagascariensis are small and that their voices intergrade. [8] Therefore the rainforest and Torotoroka scops owls become subspecies under the new name Madagascar scops owl, taking the scientific name Otus rutilus . [8]

Scops owls are typical owls in family Strigidae belonging to the genus Otus and are restricted to the Old World. Otus is the largest genus of owls with 59 species. Scops owls are colored in various brownish hues, sometimes with a lighter underside and/or face, which helps to camouflage them against the bark of trees. Some are polymorphic, occurring in a greyish- and a reddish-brown morph. They are small and agile, with both sexes being compact in size and shape. Female scops owls are usually larger than males.

The Rajah scops owl is a species of owl found on the islands of Borneo and Sumatra. The bird is named after James Brooke, Rajah of Sarawak. Based on patterns of speciation in other endemic montane bird species of the same region, it may potentially have to be split into two distinct species; if so, the name Otus brookii would be restricted to just the Bornean population.

<span class="mw-page-title-main">Principe scops owl</span> Species of owl

The Principe scops owl is a species of scops owl found only on Príncipe Island of São Tomé and Príncipe, an island country in the Gulf of Guinea off the coast of Africa. First noticed by its distinctive nighttime call, it was formally described in 2022. The first records of suspicions of its existence are from 1928. Given its low population numbers and tiny range, researchers have asked the IUCN to declare it Critically Endangered. Its distribution is limited to native forests where human activity is low—in fact, its range is entirely within a protected area, the Príncipe Obô Natural Park—and it seems to prefer larger trees. It feeds on insects. Its predators include the Mona monkey and the black rat.
