Actually, this may have been an animal coming to the end of his competitive powers as successful stags only last a few years (the competition is very energetically demanding). We have also noted the demise of Paul the Octopus (Octopus vulgaris) the mollusc who alledgedly successfully 'predicted' last summer's football World Cup results in a German aquarium (http://www.bbc.co.uk/news/world-europe-11626050 ). Paul was originally from Weymouth in Dorset and appears to have lived about the average duration for such animals. In spite of this, there are conspiracy stories that he died 3 months ago. Perhaps conspiracy theories are always generated by 'fame' irrespective of the species of the animal. It gives the media something additional to write about.

http://www.bbc.co.uk/news/science-environment-11575214 ) that the coats of big cats (including the leopard) reflect their hunting styles. Will Allen from Bristol University has studied the coat patterns of 35 species and has linked these to hunting styles (ambush predators versus animals that chase their prey) and the time of day/night at which the species hunts. Leopards (as suggested by Kipling) seem to have complex, irregular spots because they tend to hunt at night in dense forests.

This 'story' has been running for a couple of years but it is now suggested that "these testosterone-fueled" (actually a bit a speculation) are actually more of a threat to the endangered UK Red squirrel. Melanic mammals are quite common and I really don't think the situation for the Reds has changed much at all (unless the black variety are favoured other the greys when it comes to 'culling' policy). There was also a report that wind turbines (increasingly dominating our landscape) might be better painted purple rather than the traditional white (http://www.edie.net/news/news_story.asp?id=18823&channel=0&title=Purple+wind+turbines+could+save+wildlife+ ). The argument seemed to be that purple would (unlike white) not attract many insects that, in turn, act as a beacon for birds that feed upon them (and predators of those birds?). It might well be of benefit to wildlife but I am not sure about the visual impact on the environment.

My basic concern is that many of the organisms featured, given a 'second chance', are actually alien species (such as Sika deer) that are subsequently released into areas that might well suffer from their attentions. I do think that people operating in this fashion ought to think very clearly about what they are really doing (the fact that humans caused the problem can't be the only justification).
