i find filters are a help by dimming the light, i think a filter causes less alarm because some of those high powered lamps hurt the fox eyes with the glare and then they scamper off... i heard someone else say it too

simple question

 

are foxes coloured blind

 

dobby :victory:

Aren't all canines colour blind? I,m fairly sure they don't see the same colour range as humans. :hmm:

 

Firstly foxes are Vulpines and not Canines

 

And the short answer to the question is Potentially not! There are some inherent pitfalls in trying to assess the presence of colour vision based solely on looking at the number of colour-sensitive (cone) cells on the retina. Moreover, there is the problem that colour is highly subjective, existing only in our minds! Generally, psychometric tests are also needed to assess the colours that animals are able to see and respond to. However, although the psychological experiments have yet to be applied to foxes, studies on their retinal topography -- that is to say, studies looking at the type and distribution of cells on the retina -- have shown that foxes certainly have the ‘equipment’ to register some colour, although the degree to which foxes are able to resolve colours is probably less than ours. Indeed, given the roles that dogs play in our daily lives (perhaps most importantly as guide dogs), it is something of an oddity that there are so few studies looking at the vision of canids – many of those that do exist have produced dubious or conflicting results. However, observations on the activity patterns of canids do suggest that they are “visual generalistsâ€, able to work in conditions of various light intensities. For example, I’ve just returned from walking the dog – the weather is bright and sunny and it chased anything that moved as we walked around the woods. Similarly, anyone who has taken their dog out at dusk or at night can vouch for the fact that, while they may not be able to see the path they’re walking on, their dog is off investigating the undergrowth. Observations of fox movements suggest that they are able to cope with a wide variety of light conditions; foxes are active during dawn, daytime, dusk and throughout the night.

That's what I reckon too. I spent many nights lamping with my old Blue Eye 200,000CP lamp and cannot see the point in having anything more powerful that you can light up a fox 2 miles away. No rifle shot should really be attempted at 150 yards plus IMO, and no dogs need to be slipped on game so far away.

 

It seems all the rage to have an X-Million CP light but if all you're doing is ruining your chances then perhaps it is not such a good idea. Good fieldcraft will get you within range of most and then they only need lamping once as they won't live to tell the tale. Why pay good money for a high power lamp only to want to 'dim the light' with a filter??

 

The red light spectrum is also used by military personnel as distance cannot be judged using red light, maybe that is why the fox lingers a little longer with a red filter on . . . ;)
