Cuckoo Clocks Up the Miles


People have been amazed by the travels of Onon, the Cuckoo, who has been tracked making a 216,000 km round trip from Mongolia to South Africa and back whilst the world was in Covid-19 lockdown (https://www.theguardian.com/environment/2020/jun/26/cloud-cuckoo-land-how-one-birds-epic-migration-stunned-scientists-onon-aoe). This is a record for a land-based bird species (as distinct from the terns that were lauded for their travels) and it shows us how much we have to learn about migrations in what we thought were well-documented species.

Unusually, a Mute swan ( Cynus olor ) was floating on the Loughor estuary near Bynea.
