Tennyson still in central Congo

21 Feb 2020
Since moving in to central Congo around a month ago Tennyson has been spending his time moving around the rainforest in his location. We are receiving lots of infoamtion from his tag that shows he has been frequenting an area of around 30sq KM (16sq miles). It will be interesting to see whem he makes his first move north.

Tennyson moves south-west

03 Feb 2020
At the end of January, Tennyson made a journey of 205km (130 miles) south-west, moving back into a central area of the Republic of Congo.

Tennyson in the DRC

16 Dec 2019
Tennyson has recently flown 200 km (129 miles) south-east to his current location, hopping over the border and into the Democratic Republic of Congo. He is close to the Ubangi river and the Ngiri nature reserve, an area of swamp forest.

Tennyson in the Republic of Congo

03 Oct 2019
Tennyson has quietly continued onwards, flying over the border into the Republic of Congo. He is currently in the Nouabale Ndoki National Park, an area of over 4,000 square kilometers of lowland rainforest. He has chosen a good spot as this is an intact forest ecosystem where wildlife who reside here have had little or no contact with people. 

Tennyson arrives in Cameroon

18 Sep 2019
Over the last few days Norfolk Cuckoo Tenysson has flown 644 km (400 miles) south from Nigeria into Cameroon. He is the first of our tagged Cuckoos to make this next leg of the journey and he is now in far eastern Cameroon, close to the border with Central African Republic. It is the rainy season in this area now and the weather today will be between 68 and 83 F (20 to 28 C) with 76% humidity and thunderstorms bringing a 40% chance of rain. This is probably another stop-over point for Tennyson and we expect him to move further south over the coming days or weeks.

A challenging autumn migration

04 Sep 2019

The last few weeks have been quiet and for those who had not yet completed their desert crossings, it looks like the challenging conditions have claimed more of our tagged Cuckoos.

Unfortunately no further signals have been received from Knepp. From the temperature data and movements at the time, he was alive on 12 July, when we last heard from his tag. Though the battery charge had been low for a few days, there is no evidence of long term battery decline so we can't be sure what has happened to him - either he, or the tag, appear to have died suddenly. 

Lambert, who was still in France, has not moved on south and signals on 21 August showed high temperature fluctuations across the day, indicating the bird's body temperature and behaviour were not regulating it. We've heard nothing since then, and his tags battery charge had suddenly dipped, all of which leads us to believe he has likely died.

Unfortunately the challenging conditions have also impacted on Nussey who has already attempted two trips to Africa and retreated to Europe.  Abnormally low temperatures were received at the time of the last messages (16 August), having previously been fine. He was not migrating at that time, so the low temperatures were not due to high altitude, and the battery was also much lower than previously, further suggesting he was dead.

The droughts and exceptionally high temperatures in Europe appear to have proved difficult for our Cuckoos this year, however the five south of the Sahara are still regularly transmitting. Valentine, PJ, Carlton II and Tennysons' tags have all sent signals during September and the last signals received from Senan's tag were at the end of August and show him still in Burkina Faso.

Tennyson still in Nigeria

21 Aug 2019
Tennyson seems settled near Gwardena in Adamawa State in north eastern Nigeria, where he has been since 28 July. 

Five across the desert

14 Aug 2019
So far this year, five Cuckoos have made it successfully across the desert. Carlton II, PJ, Senan, Tennyson and Valentine are all south of the Sahara and still sending regular tag transmissions. They still have a little further to go south before reaching their final wintering destinations.  

Tennyson in Nigeria

13 Aug 2019
Tennyson moved into the Adamawa region in northeast Nigeria at the end of July and recent signals show he has remained in the area since. 

Tennyson crosses into Cameroon

26 Jul 2019
Tennyson clocked in at 03:06 this morning (Friday July 26) with an update showing he has flown 270 km (168 miles) south east from his last location in Nigeria over the border into Cameroon. He is now in the North Province of Cameroon, and is just north of Faro National Park.
