Torotoroka-Zwergohreule ( German )

provided by wikipedia DE

Die Torotoroka-Zwergohreule (Otus madagascariensis) ist eine Eulenart aus der Gattung der Zwergohreulen. Sie ist auf die Insel Madagaskar beschränkt und wurde einst der Madagaskar-Zwergohreule (Otus rutilus) zugerechnet.

Beschreibung

Die Länge beträgt 20 bis 22 Zentimeter, das Gewicht 85 bis 115 Gramm, wobei das Weibchen über 15 Gramm schwerer ist als das Männchen. Die graue Morphe als häufigste Form hat eine bräunlich graue Oberseite mit einem deutlich ausgeprägten weißen Schulterband und eine hellgraue Unterseite mit langen schmalen Schaftstrichen. Die braune Morphe ist sehr ähnlich, der Grundton aber bräunlich. Die sehr seltene rote Morphe ist ziemlich einheitlich rötlich braun mit dunkler Strichelung. Die Federohren sind kurz, die Augen gelb und der Schnabel schwärzlich, die Beine stark befiedert.

Die ähnliche Madagaskar-Zwergohreule hat einen kürzeren Schwanz, zum Fuß hin unbefiederte Tarsi und eine undeutlichere Zeichnung der Oberseite. Ihre braune und rote Morphe sind viel häufiger, und der Ruf klingt deutlich anders.

Lebensweise

Die Eule bewohnt Trockenwälder im zentralen Hochland und in den Niederungen, auch in schlecht erhaltenen Lebensräumen, und erscheint manchmal in Dörfern. Der Ruf ist ein zwei- oder dreisilbiges Schnurren in Strophen von drei bis fünf Lauten, der oft und in unterschiedlichen Abständen wiederholt wird.

Verbreitung

Die Torotoroka-Zwergohreule lebt endemisch in West- und Südwest-Madagaskar. Damit stellt sie ein ökologisches Gegenstück zur Madagaskar-Zwergohreule dar, die in den höheren Lagen und im feuchteren Osten Madagaskars vorkommt.

Torotoroka scops owl

provided by wikipedia EN

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]

El autillo de Madagascar (Otus madagascariensis)[1]​ es una especie de ave estrigiforme de la familia Strigidae. Habita en bosques secos de Madagascar.[2]

Distribución

La especie está muy extendida en el oeste de Madagascar, pero los límites de su distribución son inciertos, ya que su área de distribución se superpone con la del autillo malgache (Otus rutilus) con el que ha sido considerado de la misma especie.[3]

Otus madagascariensis ( Italian )

provided by wikipedia IT

L'assiolo torotoroka (Otus madagascariensis (A.Grandidier, 1867)) è un uccello della famiglia Strigidae, endemico del Madagascar.[1]

Descrizione

È uno strigide di taglia medio-piccola, che raggiunge lunghezze di 22 – 24 cm e un peso di circa 100 g.[2] Il piumaggio è prevalentemente marrone screziato, più scuro sul dorso e più chiaro sul ventre.

Biologia

Alimentazione

Si nutre prevalentemente di insetti e anche di piccoli vertebrati.[2]

Riproduzione

Nidifica all'interno di cavità naturali o in nidi abbandonati da altri uccelli, deponendo da 2 a 5 uova per covata.[2]

Distribuzione e habitat

La specie è diffusa nella parte occidentale del Madagascar, ma i limiti della sua distribuzione sono incerti, poiché il suo areale si sovrappone a quello dell'assiolo malgascio (Otus rutilus), con il quale è stato per molto tempo assimilato.[3]
