Helpful Hints
Here are some things to consider when organising your night stalk.
- Choose a fine, moonless night to conduct your survey.
- Often you will hear an animal before you see it. Keep noise to a minimum, as noisy behaviour will scare animals away.
- Use a light that is less than 30W, as this will increase your chances of finding an animal and they are more likely to behave naturally and are less likely to move away. A powerful torch such as Maglite or Dolphin torch is suitable.
- Red cellophane can be used to filter your light once an animal has been sighted. A filtered light can increase your viewing time because it is less distressing to nocturnal animals.
- Do not hold any animal under the spotlight for too long. They may panic and injure themselves. Nocturnal animals have eyes that are sensitive to light and you may attract predators like foxes and cats.
- Domestic pets should not be taken on spotlighting surveys.
- Wildlife encountered should not be fed, handled, chased or provoked.
- Use existing nature trails, tracks or roads when spotlighting, so as not to damage vegetation or disturb animal habitats.
Tips for seeing "eyeshine"
The reflection your torch creates when it reflects off the tapetum in an animal's eye is called eyeshine. The colour and brightness of eyeshine is different in different animals. Humans have a dull red eyeshine (which you often see in flash photographs) while Brush-tail Possums have a bright pinkish eyeshine.
The best way to detect eyeshine is to hold the torch or spotlight close to your eyes, so that you are looking directly down the beam. A head-torch is ideal for spotlighting for this reason.
Increase your ability to detect eyeshine by practising on spiders. Spiders have a very bright blue/green eyeshine that sparkles and can be detected from quite a distance away (sometimes up to 200 metres).
