October summary

The highlight of October was the return of Redwings.

The first this year was caught on the Teifi Marsh on the 15th October. The following morning, Charlie also caught one at his Llanfynydd site and noted the consistency of the usual dates of his first each autumn.
It has been a good year for them with a total of 200 for Charlie so far. His sites at Fygyn Common and Llanfynydd have provided good variety and experience for our trainees in a generally quite quiet month. 506 birds processed in the month at the two sites.

When weather has allowed we have been ringing on the Teifi Marsh but with key members of the group busy with other things the number of sessions has been limited.  The expected mix of Goldcrests, Chiffchaffs, Thrushes, decreasing numbers of Blackcaps and a variety of Tits. Amongst the birds that had been ringed in previous years was a Blue Tit ringed in 2011.

According to BTO birdfacts the average lifespan of a Blue Tit is only 3 years so this one 7 years is doing well.
The best news of the autumn though is that after not catching, seeing or hearing any Cetti's Warblers on the Teifi Marsh throughout the breeding season we have now ringed 5 compared with 41 last year  and a retrap from last May 2017.  What we don't know is whether our birds died in the freezing weather in April or moved away. Hopefully we will start to catch more of our previously ringed birds once the unsettled weather passes and we can open some nets again.

Recent news of several recoveries of our birds, the first three on their first migration south

November has started with wind and rain. We have lots of plans and enthusiasm but need the weather to settle. Rock Pipits number have increased in the estuary so we will again be using spring traps on the shore. Woodcock are returning so our long term monitoring of those and other species that roost on sheep pasture will start again.
