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

怎样认出它

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

常被误认为： 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

毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

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

它对人有多危险？

对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

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

它害怕时会做什么？

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

如果它咬人

把伤口洗干净并就医。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

事实

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
