Inspired by a love of lyrical poets, Tennyson is named after Lord Alfred Tennyson. Tag sponsor and namer, Gillian Wills, expressed that she felt the name has just the right number of syllables and provided the right amount of dignity for a Cuckoo.

03 Oct 2019 - Tennyson in the Republic of Congo
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.
18 Sep 2019 - Tennyson arrives in Cameroon
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.
04 Sep 2019 - A challenging autumn migration
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.
21 Aug 2019 - Tennyson still in Nigeria
Tennyson seems settled near Gwardena in Adamawa State in north eastern Nigeria, where he has been since 28 July.
14 Aug 2019 - Five across the desert
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.
