British cuckoo migration update


This video is called COMMON CUCKOO, Finland.

BTO cuckoos – Mostly in Africa now

Better weather this year has been a boost for migrating cuckoos

August 2013. Since 2011, the BTO have been fitting satellite tags to Cuckoos in different parts of the UK with the aim of finding out what Cuckoos do once they leave for the winter months, and the information that these intrepid birds have provided has been a real eye-opener. Before 2011 the wintering location of British Cuckoos was unknown but these birds have shown that our Cuckoos spend the winter in and around the Congo Rainforest, arriving there in September and leaving again, via West Africa, in February.

With the aim of getting as much information as possible, the BTO have added a new group of Cuckoos to the project. Birds from Devon, Sussex, East Anglia and Scotland have joined those that made the long journey back to the UK this spring, one of which was first tagged in May 2011.

Where are they now?

On the 6 August, the cuckoo known as Derek became the tenth Cuckoo to transmit from Africa, Chance revealed he had made it on the 8 August and Skinner on the 9 August. Derek is currently in Nigeria. Skinner who took the same westerly route, is in Mali while Chance, who took the middle route from Italy to Libya, is slightly further north in Niger.

Ryder is re-attempting his desert crossing from Morocco, locations indicate he was over Mauritania and about half way across the desert.

Still in Europe

Patch is also moving south and is now in Italy but currently remains the most northerly of all the tagged Cuckoos! If Nelson, David and Whortle don’t make a move from their current locations in France, Montenegro and Spain, this could change fairly soon! We’re wondering whether David could try to time his arrival to Africa on a similar date to last year, which was 15 August. However, having arrived later in Montenegro he may decide to stay there for the same length of time as last year (roughly six weeks) before moving on.

We haven’t heard from Nelson or Dart (last transmission from Mallorca) since mid-July so we hope to hear more shortly which will reveal their whereabouts.

Better weather

It does appear the conditions have been a lot more favourable for our tagged Cuckoos this year, with 12 Cuckoos in Africa and across (or attempting to cross) the Sahara Desert. Of those not mentioned above already, there are five Cuckoos in Chad: Waller, Livingstone, Chris, BB & Sussex – the latter of which are only 5km (3 miles) apart! Ken and Nick are in Burkina Faso, while Tor is in Nigeria.
