Are there bats in Perth??

Yes, yes and yes. Bats are found almost everywhere, even in the metro area. It’s just that  they are small, come out at night and are difficult to see. I had an email from a lady living in a suburb called Willetton, where a six lane highway thunders past her place. She found an dead emaciated bat and wanted to know more. It was under her Brazillian Pepper tree. What was it looking for??? A place to roost most likely. What do bats need??? Water. You don’t have to be near some bushland or lakes/river to have bats. Research has shown they will fly down to a swimming pool and scoop up water to drink on the go. Your chances of occupancy will increase though living within 4 to 10kms from a lake or river. Homes. They need a place to stay. Just like us. A bat box is the best home you can provide.  Once they find it they’re extremely loyal and will stay for years. And the best part. One microbat eats 1,000 mosquitoes per night….. So why not install a bat box and go for it.

Anabat SD2 bat detector

If you’re one of the lucky ones to own one of these detectors, then this two part instructional video might help you. I’ve designed/modified and built a pistol grip that enables the operator to comfortably carry the detector for hours on end. Coupled with the HP Ipaq 212 Enterprise model PDA it becomes an awesome machine. Studying bats brings on a new dimension when you can see the actual ‘real time’ calls while looking at the PDA screen.

Big Moon Rising…a time for hunting.

I read about it in the local paper. The moon will be it’s biggest and brightest tonight. Apparently this is a rare phenomenon known as a supermoon. It happens about every 18 years or so. It was bright. The trees were casting shadows and anything glossy on the ground appeared to glow. Well, I decided to see if it adversely affects the bats. Nope. They were out in force. Some people think that nocturnal animals don’t like hunting on a full moon night. I was out in my local bat research area testing some modifications to a Anabat bat detector. The ground I was walking on had many truck loads of mulch spread around. This was creating a small micro climate where small white moths were flittering out, rising from the ground. What a boon for the bats. They were flying about 1m off the ground. I even managed to see one hover just above the mulch and tilt down and snap up an insect. I was using a torch (LED lenser P14) with the barrel setting on wide beam. It was held against my right cheek. This method is used to detect the eyeshine of nocturnal animals. Our micro bats don’t have eyeshine. While I was waiting for the bats to fly past I’d check out the immediate ground for frogs. Well, The next thing you know a bat flew up to my face and caught a insect directly in front of me. I nearly wet myself….Talk about erie… You see the glow from my torch was attracting insects.
What an experience…..
You never know what to expect…

Bats stay cool

Well, here in Perth, Western Australia, the February/March weather has been really hot hot hot. In fact a record has been broken for the longest period of temperatures greater than 30deg Celsius for a few weeks. Not only humans are suffering but the poor bats are finding it tough too. A small colony of gould’s wattled bats decided it was time to find something cooler so they chose the “Coffee Stop” boxes. Normally, they only stay in these abodes for a overnight stop then move on. But this time they’re staying for a longer period. Due to the open design it has great air flow beneath the entrance. They seem to love it. Roll on the cooler weather…..I bet the bats are thinking that too…

Who's hiding there????

Baton bat detector review

Baton bat detector

Unfortunately for me my first Baton unit was faulty. I contacted the company and they sent me a new one.
Now this one works as advertised. It’s incredibly ergonomic to hold and being very light makes it comfortable to walk around with during the night. The on/off button is firm. Also there is a LED light so only one glance tells you the state of the machine.
The ‘Line In” jack at the side is excellent to accomodate a cable which can connect to a netbook or laptop. The supplied software works to show sonograms of the bat calls.
On my wish list to improve this model I would like to see a wrist strap and an extra ‘Line out” jack to have the ability for a set of small earphones inserted. There is a constant “white noise” in the background but after a short time the ears tune this out. It’s not a big issue because your ears really listen for the “tick, tick,tick sounds rather than one constant tone.

For its price I would highly recommend it. It does the job quite well.
