veil-owl

veil-owlScientific name:
Tytonidae

Natural spread:
Asia, Africa

nine manners of the veil-owls, among them also this us known veil-owl (Tyto alba) with its wide spread, is summarized in a type Tyto.

Mask-owls The second type of this family includes only 2 types, the mug-owl or bay mask-owl (Phodilus badius) of the indomalaiischen area and this for it relative Congo-mask-owl (Phodilus prigoginei) Africa (Zaire) near. Both types are inhabitants of the dense jungle. Is as good as nothing known over the African mask-owls. The bay mask-owl Asia gains a length of 29 cm; it has short "feather-ears" and a wide forehead-part so that the face seems almost triangular. In the light face-veil, the maroon rings attract attention strongly about the eyes. Both sexes externally completely immediately look. These owls live purely nightly on 1500 m in dense, evergreen forests as far as to heights, on the day, they rest in tree-caves. With the short, rounded off wings, mask-owls can move well in the branch-tangle. they hunt lizards big insects, frogs, but also smaller mammals and birds, as examinations showed at Speiballen.

Brood From March to May erbrüten these rare owls 3-5 pure-white, round-oval eggs. As Nistplätze, they visit ungepolsterte tree-caves, that are used consecutively several years. Details of the brood-biology are not known.

Veil-owl The veil-owl (Tyto alba) is one of Germany's most known owl-birds about through its preference for steeples, ruins and barns as Nistplatz. In not of people populated areas still breeds it in rock-niches and caves, also in hollow trees. This 34-36 cm long owl is through the heart-shaped veil, that longer runs and the (with most subtypes) light underside of the actual owls clearly distinguished.

The face-veil is not always, as with quietly correct animals, extended far but is pulled together with concern, so that the eyes of the veil-owl only are deep in downright pleats hidden. While they divide loot, veil-owls put the feathers in the face far back through what the veil always remains clean; the powerful beak then is well visible.

Brood The eggs of the veil-owls are oblong in contrast to other types of the owl-birds until elliptical; the nest-size fluctuates according to food-offer during the incubation (beginning): End of March of April, between 3-11 eggs; usually, however, it is in 4-6. The female broods from the first egg alone; it will look after on that occasion by its partner. After 30-34 days, they slip bedunten of giving birth sparsely; after 12 days, they change its first white Dunenkleid from mainly brown color second against a denser and longer. Both alto-birds look after the boys, that fully-fledged after approximately 60 days and with approximately 10 weeks independent is.

Way of life Veil-owls hunt preferred mice and other Nager until rat-size in open terrain; only in lean years, they stick more strongly to smaller vertebrates, big insects and also at small birds. Have under cold winters to suffer these owls strongly; often, its continuance then is thinned strongly. However, it recovers through numerous descendants soon in the subsequent year. If especially favorable conditions prevail, these owls even succeed with raising two yearly-broods. The squabs undertake quite wide hikes from time to time; in general however, veil-owls are stand-birds, who retain its precincts over several years away. Also, the partners remain longer verpaart together.

Voice The tone-remarks of the veil-owls are not very manifold; with it, they let perform courtship display hear a "snoring" reputation, with arousal, they - how many owls - work out with the beak, and from the squabs are quietly rasping and "chirping" reputations known.

Endangering The veil-owl is on the red list of the endangered types with us.
