Sylvester has been named by the Friends of Thetford Forest because the Scots Pine, the first species to be planted when the Forest was established in the1920s and such an iconic tree, is Pinus Sylvestris.

11 Dec 2018 - Sylvester lost
It is with a heavy heart that we have to report that we think Sylvester has died. Looking more closely at the data it seems that the location we received from his tag in the Central African Republic was erroneous - this happens occasionally. In actuallity, we last heard from Sylvester on 28 August in Nigeria, close to the River Niger. We have no clues as to what might have happened to him.
07 Nov 2018 - Concern for Sylvester
The last location from Sylvester's tag just over a week ago showed that the battery charge was low. We will have to wait and see if this improves to find out where Sylvester is. Fingers crossed he will pop-up soon.
19 Oct 2018 - Sylvester is alive
We have received a couple of locations from Sylvester's tag in the last week or so that show he is in Central African Republic. However, the battery charge is low and considering that he is now in an area of dense forest it might not get a good charge for a while - we will have to wait and see what happens next.
18 Sep 2018 - 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.
23 Aug 2018 - Sylvester is on the move
During the last week Sylvester has moved south and east, through Mali, Niger, Benin and into Nigeria. He is just to the west of the mighty river Niger and to the south of a village called Bawanka.
