Very informative video here from PestSmart, where they give an excellent lesson on remote cameras (like the ones our group uses in Tarra Bulga) and how to get the best results out of them when using them for monitoring wildlife and pest species.
This post is a summary of the Remote Camera Monitoring results over December and January 2012/13
Camera 1 – Still out of action after it was attacked by an aggressive lyrebird.
Camera 2 – Located in mature Wet Forest in the Tarra Valley was quite a prolific site, with the camera picking up lots of small birds e.g. White-browed Scrub Wrens and Bassian and Grey-Shrike Thrushes, as well as mammals such as Antechinus and Long-nosed Bandicoots, unfortunately there were plenty of Foxes and a Feral Cat present. Also plenty of Wombats, Wallabies and some Brushtails.
Tonight’s the Friends of Tarra Bulga National Park committee had one of their regular meetings. It is always interesting to make the evening trip up to Balook, as you are almost guaranteed to see an interesting array of wildlife along the way. Tonight was no exception on the way up in the last hour of daylight there were plenty of wallabies darting out in front of the car and a couple of lyrebirds doing their last rounds of the day.
After the meeting it was now a couple of hours since dusk, back in the car and around the first few bends we catch some eye shine and a shape at the side of the road, slowing down it becomes clear that it is a fox with something in its mouth. With light from the headlights and the full moon, I can see a short tail and on the other side of the foxes snout a long pointy nose, unmistakably a bandicoot, bit sad that my first live sighting of a bandicoot at Tarra Bulga had to be this way. The full moon seems to get the fauna out and about and a little further on we stop the car when we spot a brush-tailed possum on the roadside. With the car stationary it strides across, with a tiny offspring hanging tenaciously on to its mother’s back. Next sighting is a couple of rabbits, which surely would have been our preferred option for the fox to be dining on.
Before the friends started monitoring with remote cameras, there had been no official records of bandicoots in the park for at least a decade (wildlife surveys can be an expensive business). What impacts do fox numbers have on bandicoot or lyrebird populations or even rabbits? How common are other feral animals in the park and what impact could they be having e.g. cats? What else is out there that we don’t know about (Could there be any Tiger Quoll? We could guess but without some means of surveying we wouldn’t really know. The Friends of Tarra Bulga now have a network of remote cameras across the park, we aim to use them to the best of our ability to get a much greater understanding of what is happening out there with all them critters.
When we checked one of the cameras after some of the recent windy weather, we arrived at the site to find it had had a close call with the base of a fallen tree landing only inches in front of our precious camera.
Figuring the the tree would be completely blocking the line of sight for the camera it was thought that there was no point leaving it in its current position. So the camera was relocated.
Later while checking the results computer we found there had been some interesting activity at the site with passing Echidna’s and Bandicoots and a Male Lyrebird strutting around and calling.
After the tree fell we were not expecting much but the disturbance and obviously caused interest in feeding opportunities for some fauna. Antechinus and Eastern Whip Birds featured in a number of shots foraging in the rotten wood at the base of the fallen tree. As the tree was very close to the camera the shots are a little out of focus but they do give us a good look at the habits of species we would not have seen without the presence of the camera.
This little critter nearly went by unnoticed until we went back through some remote picks and spotted it here. It is an Agile Antechinus – Antechinus agilis. They mainly feed on invertebrates such as spiders and beetles. Like all antechinuses, the Agile Antechinus has a short and violent breeding season, after which the males all die.
