Hi @HelenCross, I cant see any ear tags (nor holes in the ears where tags were torn out) so I'm thinking that by 'white collar' you mean a natural marking, not one of the research collars. (If the latter, needs to be removed by Claire Wimpenny's team, the sooner the better). Cataract on right eye is so severe she would only tell changes in light level on that side. White on muzzle indicates old age. If we could see her molar progression it would probably show she was quite old. Urambi Hills NR is unculled and only very lightly predated by stray dogs and foxes, so with only disease, parasites and starvation to administer the coup-de-grace, more of the aged animals persist in the population. Where there are dingoes, there are few or no animals like this.
Sorry, I meant a natural white collar. Thanks for that info Don. I was with a Canberra Birds group and did a loop around that lowland area of Urambi and saw hundreds of Eastern Greys and a few Red-necked Wallabies
