Apparently using a red filter over a normal torch still allows you to see the animals, but doesn't harm their eyes as much. However, one hopes that common sense prevails... :?

There is another Topic Here which does mainly deal with the spotlights on drives but is still relevant.
I will merge them together shortly! :thumbs_up:

Whenever and where-ever spotlights are used in parks, such as on night-drives, etc, red filters should be compulsory.

I entirely agree that there is too much flashing & spotlighting going on. Some reserves are very strict about its use. Permanent eye damage is unlikely but behavior disturbance is a problem. Someone reported an owl flying away from lights straight into a tree.

I have recently posted the views of experts on the effects of spot lights & flashlights on animal vision
http://www.africaraw.com/Triptips/Trip-tips/21666409_Dp9Xv3/

To try & provide more insight into the subject of night vision I also discuss its physiology on our blog in a simple (??) washbasin analogy to explain factors influencing the input & output of visual pigment.

[urlhttp://blog.africaraw.com/?p=131][/url] for part 1

http://blog.africaraw.com/?p=143 for part 2

In practice we have become much much more careful about using our spotlight (Lightforce with red filter permanently on) & flash photography

One wonders why the shops in the rest camps sell 10m candle power spotlights. Yeah, that's ten million candle power!

As for red filters, that's a commercial non-starter. A lot of people, especially the elderly, have great trouble seeing anything in red light, and it makes (video)photography nigh on impossible. Private game lodges that have tried red filters abandoned them real quick for these reasons.

My comment is that surely if you were to use a torch this powerful for night spotting in the park then you could do some serious damage to an animals eyes, especially the owls.




Certainly . And remember , owls fly amongst trees , dodging branches , etc . It can impair his vison to the extent that he cannot see such branches , and colliding with it , could cause a broken wing , and a certain dead owl .

Hi everyone

I was just thinking of something similar but my question is completly different come to think of it.

Sometimes when we enter gates as soon as they open and this especially happens during Winter. It happens to be Dark on the roads and therefore would using vehicle headlamps be permissible. What about animals on the road which is often the case at the time. Does it affect them. Just curious

I would think you would have to Kallis in order not to knock or run over anything.
Just in the case of encountering Ellies, I would switch them off immediately as we have found they do become irritated by the car's headlights.

We have touched the subject of using spot lights in camps, but I can't find it.
I have some serious problems with the use of spot lights in camp especially at the fences.
Parents think it is OK to give spots to the children who shine the lights up and down the fence and even at people sitting silently at the fence and thereby spoiling the atmosphere.
It sometimes resembles a scene from the second world war during the Blitzkrieg over London.
Where I normally go, the use of spot lights inside the camp area is strictly forbidden and such an offense carries a heavy penalty.
People should be considerate when using the lights.

When we were in Satara in October, the couple in the bungalow adjacent to us used a spot and went chasing after Scops owls .
Every now and then the guy would shout, "here he is , come and have a look".
I eventually went to him, asked him could I look at his wonderful powerful light .
When he handed it to me, I shone it directly into his eyes and asked him how he liked it and did he realise that by shining it in the scop's eyes, it could mean the death of the most photographed owl in the world :evil: .

Johanrebel, yeah it`s interesting, isn`t it, the fact that a red filter is a commercial non-starter. It actually means that possible damage to an animal`s eyes or a disturbance is of secondary importance to sightings for the elderly and video phtography. Makes one think!!

Hi Elsa and Okie.

I totally agree that vehicle headlamps are necessary but does it actually affect the animal's eyes those headlamps.

We own a Nissan X Trail

Image

As you can see the 2 Lights I marked, Instead of turning on the Entire headlamps, My dad only turns on those 2 lights as it provides enough light to stop if there is an animal on the road but is not powerful enough as the main headlamp, but since my dad is the one that always drives, I will be going with a friend next year June without my Dad, so I was just curious,
