Guest Macnas Posted February 7, 2007 Report Share Posted February 7, 2007 I suppose if you lived in a world of shades of grey or muted hues, you'd get to know the differences pretty well. Quote Link to post Share on other sites
reynardhunter 3 Posted February 7, 2007 Report Share Posted February 7, 2007 simple question are foxes coloured blind dobby Aren't all canines colour blind? I,m fairly sure they don't see the same colour range as humans. 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.
