All birds need to preen themselves, using their beak to rearrange their feathers and keep them orderly.
DID YOU KNOW that it is essential for ducks to preen and keep their feathers not only orderly, but watertight? If they don’t, they could drown under their own body weight!
Whilst spiders aren’t everybody’s cup of tea, there’s no doubt that intricate spider webs glistening in the moonlight are a thing of beauty. At night time, our harmless Net-casting spiders (Deinopis sp) spin small, pretty made of thick, bluish-white cribellate* silk in bushland nooks – which we sometimes spot on our guided night walks or with our Junior Eco Rangers.
Net-casting spiders can be found along the east coast of Australia in a wide variety of habitats and have a really interesting way of ambush hunting. At night, these stick-like spiders build rectangular webs (about the size of a postage stamp) and deposit spots of white faeces on the surface to act as aiming spots. The spider then hangs from a thread of silk, holding the net in its front pairs of legs and waits patiently for its dinner (see picture below).

Often, whilst eating their dinner, the spider starts building a new net for its next meal. These spiders have extremely good night vision and can concentrate available light more efficiently than owls or domestic cats making them extremely good predators in the night-time environment.
Speaking of the environment, there are many who read our blogs who care a lot about the conservation and the effects of climate change on sea levels and global fauna and flora. As a developed society, the amount of energy we use is of concern. Kingfisher Bay Resort's vision since opening has been to educate staff, guests and regional district – from schools through to townsfolk – about the environment and our impact upon it... so we joined the global Earth Hour community on March 23 to show what one simple idea can achieve and one person's actions can inspire.
Catch you next time, tree huggers... and if you have any fabulous flora or fauna shots that you've snapped on Fraser Island, we'd love to see them on our Facebook or Instagram pages. And, if you're interested to know more about island life, check out our Life on Fraser blog.
