This year, because there are so many Cuckoos and routes to view on the map, individual birds only show by default if there has been a signal in the last 10 days.

Currently Gowk, Gilbert, Meavy, Waller and BB have all stopped being shown by default as we haven't heard from them in this period. Don't worry, it doesn't necessarily mean anything bad has happened. There are often periods where the Cuckoos are in dense undergrowth, where the tags don't receive enough light to charge or send signals to the satellites, often just before and after big movements.

You can still view these Cuckoos on the map by ticking the box underneath their pictures. Once we receive a signal, they will automatically reappear on the main map. 

Gowk has left East Anglia, transmitting from northern Spain on 12 July.  He is already further south than many of the Cuckoos who have chosen the Italian route and his deaprture means that only Derek remains in the UK.  

While we have three Cuckoos currently touring in France (Walpole, Emsworthy and 134955) there are now just two tagged birds which remain in the UK; Derek and Gowk. While the actual Tour De France will have departed the country soon, it could be a while before we see these Cuckoos move on. Last year Derek didn't leave the UK until 17 July but the latest departure we have seen since the beginning of the project was Scottish Cuckoo Patch, who left on 26 July last year. 

With three un-named birds left we are letting you choose what to name one of our Sherwood Cuckoos!  Anyone who sponsors a Cuckoo before the end of June will be entered in to a draw. We’ll then pick one entry at random and will contact the winner who can then suggest a suitable name*. Find out how you could name a Cuckoo.
