Concern for Sylvester
Sylvester is alive
Where is Sylvester?
We last heard from Sylvester on 28 August and his last transmission showed that his body temperature was fine, which tells us he was alive. However, his battery charge was low and looking at previous data we can see that the battery charge had been falling during the previous week and not recovering. This can happen when our Cuckoos are under the thick canopy in the rainforest and we have lost Cuckoos for as much as six weeks, only for them to pop-up again once their battery gets a good charge.
Of course we don't know for sure what has happened but all we can say is that when we last heard from him he was alive and that there was an issue with the tag which we hope will resolve itself - fingers crossed.
