Otus senegalensis (Swainson, 1837) | |
The African scops owl (Otus senegalensis) is a small owl which is widespread in sub-Saharan Africa.
William John Swainson first described the species in 1837 from a specimen collected in Senegal, and initially assigned it to the now defunct genus Scops. [3] Today the species is assigned to the genus Otus.
There are three subspecies currently recognised: [4]
The African scops owl was formerly regarded as the African subspecies of the European scops owl. It was grouped with the Arabian scops owl, Socotra scops owl, and the Annobón scops owl into Otus senegalensis; however, these species are now considered to be separate. [1]
The African scops owl is a small owl, measuring 17 cm (6.7 in) in length. It is typically greyish-brown, though sometimes pale rufous or warmer brown, and is cryptically marked with streaks and mottling. Its grey facial disk has a narrow black edge, and its eyes are yellow. It has ear-tufts, which are generally kept lowered unless the bird is disturbed. [6] The African scops owl is around 15–17 cm (5.9–6.7 in) in length with a wingspan of 45 cm (18 in). [7]
The African scops owl gives a monotonous quivering distinctive "prrrp" at five second intervals. [7]
The migrant Eurasian scops owl is very similar to the African scops owl; while it is typically slightly larger, it may not be distinguishable in the field. [6]
The African scops owl is endemic to sub-Saharan Africa. [3] It ranges from sea level to 2,000 m (6,600 ft) in elevation, and is found in wooded habitats and forest edge, [6] including in gardens and mangroves. [8]
The African scops owl is strictly nocturnal. During the day, it perches close to the trunk of a tree. [8] When roosting in daylight, this species closes its eyes and extends its ear-tufts to give the impression of a tree branch, making it easily overlooked. Pairs sometimes roost together. [9] The African scops owl is not as territorial as the Eurasian scops owl and will nest in loose aggregations, with the nest sites relatively close to each other. [9]
The male and female may duet, calling all night both before and after leaving the roost site. The African scops owl lays four to six eggs directly onto the floor of a tree hollow, with laying occurring throughout April and June. Incubation lasts about 27 days, during which the female incubates the eggs and is fed by the male. Once the eggs hatch the young are fed by the female with food brought by the male. [9] The young fledge in 30 days. [3]
The prey of the African scops owl is mainly insects such as grasshoppers, beetles, crickets, moths etc. but also spiders, scorpions and small vertebrates. They normally hunt by scanning or listening from a perch and swooping down to capture prey on the ground, but will hawk for flying insects. [9]
The Eurasian scops owl, also known as the European scops owl or just scops owl, is a small owl in the typical owl family Strigidae. Its breeding range extends from southern Europe eastwards to southern Siberia and the western Himalayas. It is migratory, wintering in Africa south of the Sahara.
The collared scops owl is an owl which is a resident breeder in south Asia from northern Pakistan, northern India, Nepal, Bangladesh ,the Himalayas east to south China, and Taiwan. It is partially migratory, with some birds wintering in India, Sri Lanka and Malaysia. This species was formerly considered to be included within what is now separated as the Indian scops owl.
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 Karthala scops owl, also known as the Grand Comoro scops owl or Comoro scops owl, is a small scops owl endemic to the island of Grande Comore in the Comoro Islands.
The Moheli scops owl is a scops owl endemic to the island of Mohéli, one of the Comoro Islands.
The Anjouan scops owl is an owl endemic to the island of Anjouan in the Comoro Islands.
The African wood owl or Woodford's owl, is a typical owl from the genus Strix in the family Strigidae which is widespread in sub-Saharan Africa.
The Cape eagle-owl is a species of owl in the family Strigidae. It is one of several large species of the eagle-owl genus Bubo.
The African barred owlet is a species of small owl in the family Strigidae found in much of southern, central and eastern Africa. The taxon may be four species rather than a single species.
The chestnut owlet is a subspecies of owl to the African barred owlet in the family Strigidae. It is found in west and central Africa in two allopatric subspecies that possibly could be classified as separate species.
The red-chested owlet is a species of owl in the family Strigidae, native to the African tropical rainforest. Its habits and behaviour are poorly known.
The white-browed owl, also known as the white-browed hawk-owl or the Madagascar hawk-owl, is a species of owl in the family Strigidae. It is endemic to Madagascar.
The São Tomé scops owl is a species of owl in the true owl family, Strigidae. It is endemic to São Tomé Island, part of São Tomé and Príncipe, in the Gulf of Guinea, off the western equatorial coast of Central Africa.
The Mayotte scops owl is a species of owl in the family Strigidae. It is endemic to the island of Mayotte in the Comoros.
The Pemba scops owl is a species of owl in the family Strigidae. It is endemic to Pemba Island which is part of and off the coast of Tanzania.
Pel's fishing owl is a large species of owl in the family Strigidae, found in Africa. It lives near rivers and lakes, and feeds nocturnally on fish and frogs snatched from the surface of lakes and rivers. The species prefers slow-moving rivers with large, overhanging trees to roost in and forage from. It nests in hollows and the forks of large trees. Though as many as two eggs are laid, often only one chick is raised.
The greyish eagle-owl or vermiculated eagle-owl is a rather large owl of the northern part of sub-Saharan Africa. It was previously regarded as the northern subspecies of the spotted eagle-owl.
Screech owls are typical owls (Strigidae) belonging to the genus Megascops with 23 living species. For most of the 20th century, this genus was merged with the Old World scops owls in Otus, but nowadays it is again considered separately based on a range of behavioral, biogeographical, morphological, and DNA sequence data.
The Socotra scops owl is a small owl endemic to the island of Socotra, Yemen.
The Annobón scops owl is an owl endemic to the Equatorial Guinea island of Annobón. The current population is estimated to be around 50-249 individuals, with the population declining due to habitat alteration and destruction. When describing the species in 1903, Tommaso Salvadori noted that the birds were abundant in wooded areas at altitudes of 400–500 metres on the island. Few sightings of the bird have been reported since then.
