Samson's movements

06 Apr 2018 - No further news from Samson

Unfortunately, we have received no further locations for Samson. We are unable to draw any conclusions as to what might have happened. The new 2g tags have not worked well on the Cuckoos and his loss could well be down to tag failure but we don't really know. We are unlikely to hear from him again, even though we have occasionally lost Cuckoos for several months for them to pop-up again when they begin to move. Samson should now be in an area where the tag should be getting plenty of sunlight to charge the battery. If the tag was going to burst into life it really should have done by now.

15 Nov 2017 - Cuckoo class of 2017

In 2017, we have been trialling the very latest satellite tracking technology - this year’s cohort were tagged with 2g tags from Microwave Telemetry.

We have, unfortunately, ‘lost’ contact with most of them already. It would seem that the smaller size of the new tag allows the solar panel, used to recharge the tiny battery, to become shaded by feathers, resulting in much less efficient charging of the battery, and consequently lower contact with the tag. Although some may have died, the lack of transmissions from the tags makes it impossible to assess this and in all cases, there were no indications that the birds were in trouble when we last heard from their tags.

This is exacerbated during the winter months by the birds spending more time under the canopy in the Congo rainforest. We don’t know how the batteries will fare when the birds begin their northward migration back to the UK. On leaving the rainforest the tags should receive more sunlight which might be enough to overcome feather shading, and if this happens some of the ‘lost birds’ could pop-up again in February or March, but it is possible that the prolonged shading will have caused irreversible damage to the much smaller batteries in the 2g model. We all have our fingers crossed.

As we move forward we are continuously looking for effective ways to continue gathering this important data for Cuckoos, and other species, to benefit our knowledge and ultimately wildlife conservation. We hope that next year we will be able to track a cohort of cuckoos without these issues arising. 

09 Aug 2017 - Samson in Nigeria

Samson has travelled eastwards from Mali during the last week, covering around 1165km (725 miles) across Burkina Faso and northern Benin, to reach Nigeria. He is just west of the Kwiambana Game Reserve and north of the Kamuku National Park. 

26 Jul 2017 - 170432 to be known as Samson

Cuckoo 170432 is in Africa and is now to be known as Samson.  He has been named by TV wildlife presenter Martin Hughes-Games after his son. Samson was in Spain but a recent signal on the afternoon of 21 July shows he had completed his desert crossing and was in Mali. From here he then moved on 420km (by 260miles) to Burkina Faso, where Victor is also located. He is currently between the Red and the White Volta Rivers and just north of the town of Bane.
