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.
06 Sep 2017 - Where are Nicholas and Kidman?
Nicholas and Kidmans' tags both last sent transmissions from Italy in July. However nothing has been received since. It seems that the tags aren't charging so we do not know if they remain in Italy or have moved on. Peckham is still as far north as Belgium so it could be that Nicholas and Kidman have also yet to move further south. At this stage we have nothing to suggest that anything has happened to these Cuckoos and we hope to hear from them again.
24 Aug 2017 - No further news
No recent news from Kidman or Nicholas, whose tags last transmitted in Italy, or Carlton, last known to have been in the UK.
10 Aug 2017 - Nothing further from Nicholas or Kidman
