Thanks for your input and support Derek.
I have decided to do the full project, i.e. everything I see in the project area, photographed or not, on iRecord. I will probably do the same project area on iSpot but only for species that I can photograph; this most likely means plants and the odd insect or well behaved bird.
I only have the camera on my phone - great for plants, not so good for birds.
Regarding the "skunk-like" observation: Intriguing, have you any ideas? Possible escapee? I think there was a Honey Badger, UK observation, on iSpot not long back; I pity the native species' that cross paths with that beast.
