Chris and BB in Congo

19 Feb 2013

Both Chris and BB remain in Congo, at the north end of the Téké Plateau and have shown no sign of moving north yet. We last received a location for BB’s tag this morning and for Chris's yesterday morning. Currently just 85km (53 miles) separates the two of them.  

Update on Cuckoo locations

13 Feb 2013

Chris, BB and Lloyd have still yet to begin their northwards movements and have all transmitted, from the same positions, in the last few days. Given the pattern seen so far, we may expect to lose transmissions for a few days as they feed up before they then make their move north. 

There have been no further transmissions from David since the 2 February, just after his big move, however the tag charge was low then. Hopefully it may receive some sunlight soon and charge up enough to transmit his current location. Chance is about 270km (168 miles) away from David's last known location. 

Chris content in Congo

31 Jan 2013

Roughly 385km (240 miles) north of Lloyd's position, signals were received on the evening of 29 January from Chris' tag, but he has not moved from his previous location.  Last year, his tag was still transmitting from Congo on the 19 February. The next signal received after that wasn't until the 6 March when he turned up in Togo.  

Chris remains close

18 Jan 2013

Transmissions from Chris’s tag were received yesterday evening, he is currently 100km (62 miles) to the northeast of Chance and BB.  

Four Cuckoos unchanged

11 Jan 2013

Chance, Lloyd, David and Chris all remain in their previous positions according to locations received in the last two days.  

2013 transmissions

08 Jan 2013

So far in 2013, we have heard from four of the five remaining Cuckoos. We received tag transmissions from Chris and Chance today and from Lloyd and David yesterday showing there had been no substantial movements to report.

However, we haven’t heard from BB since the 30 December - at this stage this is nothing to worry about, though, as at this time last year we regularly went longer than this without hearing from the Cuckoos. A combination of poor charging conditions and a gradual decline in battery charge mean that they are transmitting less often, whilst as they are within the forest interference from trees reduces the chances of transmissions being picked up by satellites. Once they move on, or the weather at their current locations improves, we should start to receive positions more regularly again. 

Chris counting in the New Year in Congo

02 Jan 2013

No further movements from Chris to report but transmissions were received from his tag as 2012 ticked into 2013. We hope this year is more favorable for migrating Cuckoos than last year! 

No further movements from Chris

27 Dec 2012

Signals received on Christmas Eve show that Chris remained in his new location in the Cuvette region of Congo.

Chris moves southwest

20 Dec 2012

Transmissions received early this morning show that Chris was 225 km (140 miles) southwest of his previous location, though still within Congo. He is now in the north of the Cuvette region.  

Chris now close to his position at beginning of this year

10 Dec 2012

Sometime between Wednesday 5 December and Saturday 8 December Chris moved 116km (72 miles) north from his previous position. He is now about 16km (10 miles) west-north-west of the position he moved to in early January this year, when he remained here for about two months. It is interesting that this short northward movement has come at the same time as David’s movement of similar length and direction.
