The Cuckoo is currently Red Listed as a Bird of Conservation Concern in the UK, due to its population decline.
Since 2011 we’ve been satellite-tracking Cuckoos to find out why they are declining. We’ve learned lots of vital information which could help us to understand our Cuckoos, such as how the different routes taken are linked to declines, and some of the pressures they face whilst on migration — but there is still more to discover.
We now need to look more closely at how dependent they 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.
New updates received from Bluey's tag in the small hours of this morning (5 Dec) show that he continued south from his last location in Gabon, flying a further 1,000km (622 miles) to reach Angola.
He is now 50km (30 miles) due east of the town of N'zeto. Bluey is the second of our tagged Cuckoos to reach Angola this year, following Cuckoo Trent, who is 93km (58 miles) south of Bluey.
We last heard from George on 9 November, when he was approaching the Lukenie River, approximately 20 miles upstream of the community of Oshwe, in the Mai-Ndombe province of the Democratic Republic of the Congo.
Cuach Cores has relocated within the Congo Basin of the Democratic Republic of the Congo, flying 150km (92 miles) south from an area close to the Tshopo River to his new location close to the Maringa River.
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.
