Sterna paradisaea At Conder Pool.

It was good news this week from Conder Pool, when I hear of a 60% increase in the number of nesting Common Tern on the platform compared to last year, but the sad news is it has been the worst season for the Avocet and Black-headed Gulls since 2020 due to predation by Fox.

My news from Conder Pool on Friday was a little slim because of a major distraction, but 5 Mediterranean Gull were seen today, with 4 Greenshank and 4 Common Sandpiper. A Peregrine Falcon came over, it did a circuit of Conder Green before returning to take out a Starling and departing to the Lune Estuary.

A Major Distraction.

Howard Stockdale saw the arrival of an Arctic Tern on Conder Pool on Thursday, and in message to me he referred to....'Conder just keeps giving'....well comments like that can't be more appropriate now can they!

I became the twitcher on Friday, in the hope of a connection with this little beauty, but a birder was leaving as I arrived at Conder Green. I asked if the bird was still around to receive a negative reply as he left. Disappointed I turned the camera on to get some footage of three terns, it  wasn't until I played back the footage that I realised it was my lucky day, as one of the birds was indeed a 1st summer Arctic Tern apparently playing nursemaid to the immature Common Tern.

The bird on Conder Pool is the second 1st summer Arctic Tern in recent years to visit our area, one was at Heysham on 9 July 2020. The same bird paid a visit to Conder Pool the following day 10 July, this is only 6 days later from being the same day, same location again in July 2024.

The Arctic Tern moves on a global scale, breeding in the northern hemisphere and migrating south to the Antarctic, making the most extensive and remarkable migratory journeys of any other bird, literally crossing the world in travelling between the polar regions, the consequence of which this small bird experiences more daylight than any other living organism on the planet.

The distribution of the Arctic Tern is such that neither ring-recoveries nor observations will ever reveal the full extent of this birds movements in which there are major gaps in understanding them. It's breeding grounds are sparsely populated in the high Arctic, wintering grounds are largely uninhabited, and much of its movements occur in small groups at high altitude across open oceans. In the north they breed at a higher latitude than any other tern species, whilst populations breeding in Britain are at the southern edge of their breeding range where strongholds are in Orkney and Shetland, with a small number breeding in northern  England and on Anglesey.

Heading south to the Antarctic Seas in the non-breeding season involves a return journey for a far north breeder of a truly staggering 20,000 km at least.

I need to do some detailed research on movement of the Arctic Tern. As I see it, this bird shouldn't be in the Northern Hemisphere, let alone on a pool in Lancashire.

I'm grateful to Howard Stockdale for the info re Conder Pool breeding data, also his image of the 1st summer Arctic Tern.
