Very excited by a recent gift. Introducing The Magenta ‘Bat5’ – Digital Quartz Bat Detector, Locater and Listener. Wey hey have wanted one of these for ages and now have a bat detector of my very own.
First impressions are good, it lookes for all the world like a small portable radio (14cm x 7cm approx.). The controls are easy to use, an on / off volume control, a dial for changing the frequency you are listening to plus a large digital screen diaplaying the frequency. It also has a handy led light and two outputs, one for standard headphones and another for recording.
I also received the Magenta, Bat Detector Case, for Bat 4 & Bat 5 Detectors. This looks like a camera case and again very pleased with the product. I like the black / greeen colour, it can be worn on a belt or around your neck using the strap supplied. The case has some padding which should protect the bat detector from the occasional light knock. The bat detector is a pricey enough piece of kit, it won’t break the bank but, for me, it is out of my impulse buy range, so really the case is a must. However, if you had an old camera case of the right size I’m sure it would do just as well.
I have done a few tests with it, by listening to jangling keys and even rubbing your fingers together and all seems in order. I will update my report on the Magenta Bat 5 early next year as all the bats are in hibernation at the moment! Roll on springtime.
Some Bat Links Till Springtime
The bat walk started with with the group being shown some mummified sample bats to get us warmed up for what was to come. As dusk approached we went over to a stone building and waited for bats to emmerge. We did see a few bats here but it seemed, with the fine evenings we have been having recently, that perhaps the bats were not too hungry. We were introduced to bat detectors. Theses are hand held devices that convert bat sounds into sounds the the human ear can hear. The detectors were set at different settings to listen for different species of bat. As the night drew in sure enough, using the detectors, we could hear the bats and could see them very well sillouetted against the as the clear sky. The first bat identified was Leisler’s Bat, which we were told flies at a higher level to other Irish bats. Leisler’s Bat can be heard at 20hz on the detector. At the buildings we also saw and heard (with the detector set at 50hz) the Soprano Pipistrelle. After some time at the buildings we went over to see a moth trap set up as part of the BioBlitz. Saw plents of beatles and not many moths – very interesting all the same.
While we were watching and waiting for the bats to emmerge, bat experts had set up fine nets in known bat haunts to catch and identify some bats. We got word that they now had some bats to show us. We followed the ranger down a dark track to where the experts were waithing. We were shown a Daubenton’s Bat they had caught. Daubenton’s Bat is known as the water bat for its habbit of skimming just over rivers, lakes etc in search of food. It has large feet that it uses to catch its prey. We were shown the bat then it was released. Following the bats release we went down to a river and using the detectors and a strong lamp we watched Daubenton’s Bat in action skimming accross the top of the water. After some time we moved to the edge of the trees to detect bats as some species like to operate at the edge of woods. To fininsh off the bat experience we were shown more mummified samples of bats such as the long eared bat. On the way back to the car park we stopped off at the moth trap again to see how it had done. I helped the rangers bring the gear back from the woods and the night was over. Great night, great experience, big thank you to all at Coole park.
Note: It was such a clear sky that a number of meteroites were seen as well as a satallite travelling accross the say.
