Sie wiegen nur 15 bis 50 Gramm und doch fürchtet man sich vor ihnen. Sie sind die einzigen Säugetiere, die sich ausnahmslos von Blut ernähren.Sie sind nachtaktiv und man weiß, dass sie Tollwut übertragen können, Rinderzüchter in Südamerika würden sie lieber tot als lebendig sehen. Dabei sind die "Blattnasen" höchst faszinierende Tiere, die im Gegensatz zu vielen anderen Fledermäusen auch auf dem Boden laufen und hüpfen, und spinnenartig sogar senkrechte Wände erklimmen können.Wenn sie rennen, schaffen sie bis zu 7.9 km/Std.
Vampirfledermäuse leben in Gruppen, die aus bis zu 100 Tieren bestehen können. Insbesondere der Gemeine Vampir hat ein hoch entwickeltes Sozualverhalten entwickelt, zu dem die gegenseitige Fellpflege und auch das Heraufwürgen des verzehrten Blutes gehört, das er mit weniger erfolgreichen Artgenossen seiner Kolonie selbstlos teilt.Und sie sind die einzige Fledermausart, die Jungtiere adoptiert, wenn der Mutter etwas zustößt.-
They weigh only 15 to 50 grams, yet they are feared a lot. They are the only mammals who solely feed on blood.They are nocturnal and everybody knows that they can transmit rabies, cattle breeders in South America would rather see them dead than alive.
Yet, the "leaf-nosed bats" as they were grouped are most fascinating animals that can walk contrary to many other bats on the floor and jump, and can even climb vertical walls like spiders do.On top of it one has found out that they are even capable of running at speeds of up to 7.9 km per hour (4.9 miles per hour).
Vampire bats live in colonies, which can consist of up to 100 animals. In particular, the common vampire has developed a sophisticated social behaviour including mutual grooming and sharing food selfflessly with less successful members of his group by regurgitation of ingested blood. A vampire bat can only survive about two days without a meal of blood, yet they cannot be guaranteed of finding food every night. This poses a problem, so when a bat fails to find food, it will often "beg" another bat for food. The "host" bat may regurgitate a small amount of blood to sustain the other member of the colony.
Vampire bats are believed to be the only bat species to adopt another young bat if something happens to the bat's mother, a sign also how stong the family bond is with the members of theirt colony.

Und noch etwas, was sie von allen anderen unterscheidet, zu Halloween sind sie die Einzigen, die wirklich kein Kostuem brauchen...:))-
And as to Halloween....they are the only ones who really do not need a mask...:))

Liebe Birgit,
Deine Bemerkung darüber, dass die kleinen Vampiere von Natur aus kein Köstüm brauchen, ist sehr witzig.
Ich glaube, in unseren Breitengraden verschlafen sie Halloween sogar - sind sie nicht schon im Winterschlaf ?
Liebe Grüße
Britta-Gudrun
