BB heads north

15 Jan 2014

BB has begun the first stage of his journey back to the UK. On 11 January he was 250km north of his mid-winter location. He is still in the southern part of the Congo Rainforest, just to the north of the Téké plateau and just south-west of the settlement of Makoua. We have seen in previous years that around this time British Cuckoos begin to make their way to north of the Rainforest, before heading to West Africa.

Christmas in Congo

23 Dec 2013
Scottish Cuckoos BB and Livingstone, along with East Anglian Cuckoo, Derek, will be spending Christmas in Congo, along with Tor who is further south (and closer to Chance and Ken in Gabon). BB is currently just a little further north from the position in which he was in at this time last year. It's been really fascinating watching how some of the timings of movements have been so in sync with previous years' data and we hope to continue to collect sequential year's data to look at how environmental conditions influence timings and the sites which are used. 
 

BB heads south to join the other tagged Cuckoos

09 Dec 2013

In the very early hours of 5 December, transmissions from BB's tag showed that he had left his location in Chad and was heading south over the Central African Republic, towards the area where many of our tagged Cuckoos have been for several weeks.

The next period of transmissions, on 7 December, revealed he was in Congo. This most recent movement has taken him 1125km (700 miles) from his location in Chad. He is now just 55km (35 miles) from Norfolk Cuckoo Derek and 90km (60 miles) from fellow Scottish Cuckoo, Livingstone.  Desite this move south, he is still currently the furthest north. 

BB & Chance yet to move further south

28 Oct 2013

Two of our Scottish-tagged Cuckoos, BB and Chance, from 2012 are currently in the most northerly locations of those we are following this year. BB remains in Chad, while Chance is still in Nigeria.

Chance did make a move south, almost reaching Nigeria's border with Cameroon, but for some reason retreated in a north-westerly direction again. He is currently just south of Gombe. By mid-October last year, he was further south, in Cameroon, but didn't move again until the beginning of November, when he journeyed to the Téké Plateau – the area of savanna and gallery forest in central Congo.. Will we see him do the same again in the next couple of weeks?  

As for BB, last winter he spent from 17 September to 4 December in the same area as his current locaion in Chad, before then moving south to theTéké Plateau. If he does the same again this year, it may be a while before we see any further movements.

In addition to BB and Chance, this wintering area was also used by four of the Cuckoos tagged in East Anglia in the first year of the project , who spent winter of 2011/12 in the Téké Plateau, with the exception being Chris who each year has wintered in the Likouala-aux-herbes area, where he is currently. Last year, our English Cuckoos fared badly on their southward migration and Chris was the only East Anglian Cuckoo to make it to his wintering grounds. It will be interesting to see how many move south to winter in the Téké Plateau this year.

Four Cuckoos remain in Chad

22 Aug 2013

Waller, Chris, Sussex and BB are all still in Chad and sending regular transmissions. Last year Chris was the first of our tagged Cuckoos to move south of Chad, arriving in the Central African Republic by the 18 September. Not long after this the Cuckoos moved on to the Congo Rainforest. 

Sussex and BB in same area

14 Aug 2013

BB, one of the Cuckoos tagged in Scotland in spring 2012 and Sussex the Cuckoo, tagged in spring 2013 are now only around 5km (3 miles) from each other within Chad – much closer than they are during their breeding season in the UK!  BB moved to a location just south of Dassik, having flown 250km (155 miles) by 8 August before Sussex also headed south, travelling 230km (140 miles), to just north of Dassik and BB’s location by 10 August.  They are so close together you can only see one icon unless you zoom in really close on the map! 

BB arrives in Africa

30 Jul 2013

Signals on the 23 July show that from north-east Italy, BB journeyed south to the Calabria area in the foot of Italy but, just two days later on the morning of 25 July,  poor quality signals indicate he was crossing the Libyan desert becoming the fourth tagged Cuckoo to transmit from Africa. By the evening of 27 July he was in south-west Sudan and had completed his desert crossing.

From here he then moved west a further 355km (220 miles), into the Guera region of Chad.  He is 65km (41 miles) north-west of Mongo, the capital of the region.

BB in Italy

28 Jun 2013

The latest transmissions received yesterday evening (27 June) show that BB has left Germany and is now in north-east Italy.  He is near Valvasone, a comune in the Province of Pordenone in the Italian region Friuli-Venezia Giulia. This new location is 330k (200 miles) from his last position in Bavaria. 

BB in Germany

26 Jun 2013
BB has covered 690 km (430 miles) from the Friesland Islands, and on the 25 June was in the south of Germany,  close to Abensberg, a town in Lower Bavaria, 100 km north of Munich. It is situated on the Abens river, a tributary of the Danube.  
 
We have also been involved in another Cuckoo tagging project in Germand and Belarus. In Germany, Chris Hewson traveled to help catch and fit tags near Regensburg and it looks as though BB has gone to join the German birds! We are collaborating with the Landesbund für Vogelschutz (LBV) who are leading the project and BirdLife Belarus (APB). BB actually  flew right over Hilpoltstein (south of Nürnberg), the headquarters of LBV!

BB leaves the UK

21 Jun 2013

From his location close to Loch Katrine, BB has become the second Cuckoo to leave the UK! Interestingly, he has timed it almost exactly as the year before. His last transmission from Scotland was on 18 June, the same day he was tracked crossing the North Sea last year, and the next one, received early on 21 June, showed he had made land at the Friesland Islands in The Netherlands.  As last year, he made a large sea crossing; from the east coast of Scotland straight across to The Netherlands,  not attempting to minimise this by heading south first and crossing at a point where the sea was narrower.  Last year, BB quickly moved on and was in Germany by 20 June.  Transmissions next week will show us whether he has done the same in 2013.
