Chubsta where my parents lived in Yorkshire they had two phases of toads spawning I think it was. I will check with my brother on this but I think it was toads. I am talking about hundreds and hundreds of toads breeding in large ponds.

@Chubsta - that's what I was suggesting - ie that there is relaxed selection pressure in the garden compared with the wider countryside that allows alleles for odd/bright colouration to persist at higher frequencies than usual.

@Ben - thanks, I'm not against the idea that environmental factors might trigger genes for odd colouration epistatically, as well. I'd just like someone to do the research into whether frogs in urban areas are genuinely odder/brighter than 'wilder' ones and if so, why? Also, why females are brighter/more diverse in colour than males - though that question might be easier to answer, ie females spend far less time in the grey/brown murk of ponds and hence don't need to be so well camouflaged against this background.

Hmmm...seems to be a little confusion here. I agree with you both and have done all along.
                                                                             
I was only er...pondering other possible explanations because Gemma's comments suggested to me (perhaps wrongly) that she suspected the 'unusual'
colours might be a cause for concern and signify a more sinister cause.

Hi Ben

I think I'm agreeing with everyone too! just wanting someone to investigate (give me a fat grant and I'll do it.. )
