Found bat rear

Raising bat found "Elsie" - 2011 is the year of the bat

The year 2011 has been declared the Year of the bat. That's why we spend this year in a number of articles focus on the bat. In addition, we follow the seasons.


An observant passer-by saw Elshout, near a colony of bats, a small bat on the ground. He picked up the little creature and placed it in a tree. He hoped that the way to the bat colony would find. That did not happen and the next day was the bat on the same spot as where the man had left her.
Through the animal is the bat when the bat ended up in group and it was done with care.

Although it was difficult to precisely determine the age, it was clear that it was a baby. The baby goat was that some salts had been added. As they grew well and eventually could be slowly switched to mealworms.
Because the bat was raised by people without contact with peers, was returning to nature is impossible. She was named Elsie, because of its location.



It goes very well with Elsie and it's a nice story. Elsie lucky that the man who found her her arrest but was concerned that the man was not really wise. Although the risk may not be large, it is possible that a rabid bat is. They are not domesticated animals and if you're not a connoisseur, you can not sufficiently aware of the reaction of a bat if you pick up. Therefore, the man had more right to call the animal.
Rabies Rabies is a virus or disease that can be transmitted by physical contact with sick mammals such as dogs, foxes and bats. The virus is in some European species of bats is found, the European Bat Lyssa Virus (EBLV) called. This virus is less contagious than the classic rabies virus, but one should always be careful and wear gloves.


All Dutch species of bats are insectivores. A bat needs to survive a night quarter to one third of its body weight in insects. For a bat means a night to 300 mosquitoes, moths and beetles. This means that for example a water-bat single in the period from 15 May to 15 October over 40,000 mosquitoes will eat. An average colony eats a few dozen kilos of summer insects. No other animals that night so many insects. However, many of these insects harmful to agriculture and forestry.

In the winter months there are too few insects for bats to survive. That's why they go in late autumn to find a place to hibernate them. For most species in the Netherlands, a suitable place for the winter cold and frost-free. (between 2 and 10 ° C) Humidity should be high and it must be dark. Furthermore, there is no disruption occur. For many types of conditions are found in caves and similar places such as basements, underground bunkers, forts and mines. Known hibernation sites include the limestone quarries in South Limburg, the forts of the Dutch Waterline, bunkers from World War II and ice cellars in old estates. Nowadays there are bats in many places, new artificial winter quarters built.


In hibernating bats reduce their body temperature to about 5 ° C and slow down their breathing, heart rate and metabolism. They consume very little energy and can then continue to live on their fat reserves. Hibernation may be four to six months. Bats prepare for winter by eating a lot in the fall. This is the fat percentage increased significantly so that the animals in their winter fat reserves may teren. During hibernation animals try their body surface area as small as possible by their wings and tail to the body again. Some species fold their legs behind their ears to prevent freezing.

In the area of ​​the Gardens in Demen state since several years a bat basement. Each year the bats working to keep a count. The recent census was, like the previous years, a brown-bat grootoor observed. The circumstances in which the bat hibernates, for a number of other species also favorable. When the counts in Demen are invariably observed several salamanders, including the rare great crested newt.
