We’ve been satellite-tracking Cuckoos since 2011. We’ve learned lots of vital information, such as how the different migration routes are linked to declines, and some of the pressures Cuckoos face whilst on migration, but there is still much more to discover.
An important aspect of this project is how it helps us improve our understanding of why Cuckoo are in decline:
Our Cuckoo Tracking Project is vital and it wouldn’t be possible without the amazing support from funders and sponsors.
Sponsor a CuckooWe now need to look more closely at how dependent Cuckoos are on, and how much their migration is linked to, the drought-busting rains of the weather frontal system known as the Inter Tropical Convergence Zone (ITCZ) as they move out of the Congo rainforest and begin to head back to the UK via West Africa.
Each Cuckoo’s tag sends us location data approximately every day, so we can follow them and learn more about their migration.
Hafren has now left Spain and is making his way south along the North African coast.
His route saw him setting off across the sea, leaving the Spanish mainland west of the famous Doñana National Park, before arriving on the Moroccan coast just to the north of the city of Agadir.
At 7.36 this morning, we received a signal showing that he was close to the Western Sahara border. In the last 48 hours Hafren has covered around 1,220 km (758 miles).
Henry, if the satellite information is accurate (and there’s no reason for us to assume that it isn’t), is behaving rather oddly… following his 12-day stay just to the south-west of Paris, he finally set off, but instead of heading south he took off to the north, towards Germany!
Two days ago he passed Cologne and continued to fly northwards. He then bypassed Bremen and cracked on towards Hamburg, before veering west, and at 7.56 this morning (24) we received a signal to say that he was just north of the North Sea port city of Bremerhaven!
In summary, Henry appears to have flown approximately 960 km (596 miles) in the wrong direction. Hopefully, he will soon reorientate and head south after his surprising German tour.
Since our last update, when Sayaan was in the Jalo oasis area of northern Libya, he has flown a further 1,766 km (1,097 miles) across the desert and is currently in east Chad.
He has reached the Sahel region, where he can hopefully rest and feed a little before continuing south. At 8.03 this morning (24 July) he was close to the western border of Sudan and just north of the city of Abéché, the fourth largest city in Chad.
You can help keep this important project going by either giving a donation, becoming a Cuckoo sponsor, or gifting a sponsorship to someone else. We greatly appreciate the support the project has received, allowing us to continue to monitor this endangered species.
