Sad news

12 Jun 2014
Unfortunately we have lost two of the newly tagged birds. Both Wistman, from Devon, and 134962, from the New Forest, appear to have died recently according to the temperature readings that accompany the transmissions. We cannot be sure of the reasons but one possibility is predation. 
 
Last year Karma, one of the birds tagged in western Scotland, who was the first that year to leave his breeding area, travelled to the east coast of Scotland and died there, making it only as far as Aberdeen. We wish our other Cuckoos this year better success.  

First Cuckoo leaves the UK!

10 Jun 2014

It's only early June but our first Cuckoo has already left to start the journey to their wintering grounds! Recently named Peter, one of our New Forest Cuckoos tagged this year, had made it to northern France by the 8 June. This is early for our Cuckoos but by no means the earliest. In previous years Cuckoos have left as early as 3 June. Who will be next to follow?    


Stanley last of Thetford finds for 2014

31 May 2014

Stanley was the last of three birds to be tagged in the Thetford area in 2014. On a misty morning near Cranwich Heath, Stanley hurled itself at our dummy female Cuckoo and into the net from a great distance, despite the nets being highlighted by the mist.


Walpole found in Chris' haunt

23 May 2014

Walpole was caught and tagged less than 1km north of where Chris the Cuckoo was originally found, three years before.


Maji tagged in Elveden Forest

21 May 2014

BTO's Cuckoo tagging team were accompanied by Anglian Water's Mike Drew to catch and tag Maji - who despite bright skies, and other birds avoid the nets, managed to fly in twice before before being caught.


The New Forest four

27 May 2014

Bolderwood, New Forest, Hampshire -  Six Cuckoos caught between 04:30am and 11:00am - the first three of which (two tagged, one too small) were in the first round, one in the middle of each of a triangle of nets set at Bolderwood. The other three were caught a couple of miles to the north and four were selected for tagging. This meant we completed our tagging in Hampshire during day, in a brief weather-window.


Three birds for Devon

15 May 2014

All three Devon birds tagged in 2014 (Emsworthy, Meavy and Wistman) were caught between 04:30 and 08:30 on May 15th at Emsworthy, a Devon Wildlife Trust reserve on the eastern edge of Dartmoor, along with one female cuckoo. Nets were set around an isolated Hawthorn bush on the upper valley slopes. A fifth cuckoo escaped from the net that morning.


Three birds for Sherwood

20 May 2014

The first of three Cuckoos taggged in Sherwood Forest, 134952 was caught flying between young alders near Shirebrook, after having failed to catch three cuckoos flying over our nets at Budby Common earlier that morning. The second two birds, 134955 and 134957 were trapped at Sherwood Pines the following morning, the second bird flying into the nets just as we released the first!


Tor makes it as far as Morocco

22 May 2014

In the last few days we have been receiving signals from Tor's tag - surprising us as we last heard from him just north of the Congo Rainforest in March! These new signals show he made it to Morocco but unfortunately it does look like, despite successfully completing the crossing of the Sahara desert, he has since died there. This shows that tag failure was responsible for his initial silences but unfortunately it looks like the desert crossing was too much for him and he didn't have the reserves to continue onwards. 


David back in Wales

13 May 2014

By the evening of 13 May David was back in Wales! He left his last location in France sometime after the 9 May, making the 660km (410 miles) journey back to Tregaron, the area in which he was first tagged.

Last year, in spring 2013, he first returned to the UK much earlier, around 26 April but promptly turned tail and returned to France - no doubt  influenced by the cool daytime weather and falling evening temperatures at Sherborne, and by the general lack of advancement of the spring due to the unseasonably cold weather earlier on in March and April.  Having spent a few weeks there, he was back in the UK by the 6 May and at his tagging site by 9 May. 

It's interesting that despite much warmer daytime temperatures in the last few weeks, David has chosen to leave it even later than last year. Perhaps using his previous experience to ensure that he doesn't make the same mistake again. This choice however may mean that he finds it harder to find a mate, as other Cuckoos who have arrived earlier will have taken the best territories.
