The white-winged vampire bat is a small bat that feeds on blood. It lives from Mexico to northern Argentina, and also on the islands of Trinidad and Margarita Island. Its pale wing edges make it easy to tell apart from some of its relatives.1

Hoe om dit te herken

Fur is clay-coloured, light brown or dark cinnamon brown.1
The outline of the wings is white, as is the membrane between the second and third fingers.1
Ears are 18 mm long, longer than they are wide.1
Nose to tail length is about 84 mm, and it weighs 31.7–48.1 g.1
Its forearms are 51–54 mm long.1

Word dikwels verwar met: It is often confused with the common vampire bat. The white-winged vampire bat has a smooth outer edge on its tragus (the small flap in front of the ear), while the common vampire bat's is serrated. Its thumb is also much shorter, and it has 22 teeth, compared with 20 in the common vampire bat.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

Its saliva contains plasminogen activators, which quickly dissolve the clots that form in the host's blood while it feeds. It also contains platelet aggregation inhibitors and other anticoagulants, which stop blood from clotting. These compounds work especially well on birds.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.

It can transmit rabies, but this appears to be relatively uncommon. The only reports of rabies transmission from this species come from Trinidad.1

Wat doen dit as dit bang is?

When disturbed, it produces a foul-smelling odour from cup-shaped scent glands in its mouth, which may help deter predators.1

As dit byt

Was die wond goed en kry mediese hulp.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

In captivity, each bat drinks about 16 ml of defibrinated cow or chicken blood per day, and they should be kept in social colonies with dominance hierarchies.1

It is the only bat species in the world with 22 teeth, although older individuals sometimes lose the last upper molars.1

Its brain is large for its body size, which may be because its hunting needs careful planning and stealth.1

It is not as good as the common vampire bat at walking on all fours, but it is quite good at climbing branches.1

It roosts with many other bat species, including the common vampire bat.1
