The next day Andy tried a final (evening) visit to the jetty for just 6 birds - Sand Martin 2, Swallow 1, and Chiffchaff 3. Our visits to the jetty have been very successful this year, with some 850 birds ringed since early July in just two nets. As well as contributing to our Reed Warbler RAS study, we also successfully monitored the Sand Martin/Swallow roosts and general warbler passage.
On 18th, George had a less successful catch than on his previous visit, of 15 + (3) - best were 4 Blackcap & 3 Goldcrest. On 19th, Jerry and Madeleine had 30 + (1), incl 12 Chiffchaff & 7 Goldcrest. On 22nd, Jerry was back for a catch of 22+ (1) incl 7 Goldcrest & 5 Blackcap. The full mix for the three sessions was Wren 2, Robin 4, Dunnock 2, Blackbird 2, Chiffchaff 15, Blackcap 13, Reed Warbler 2, Goldcrest 17 + (4), Blue Tit 2, Great Tit 1, Treecreeper 1, and Bullfinch 6 + (1).
There then followed a period of unsettled weather, and visits were reduced/affected. On Tuesday 27th, Andy had a delayed start (with occasional light showers and a moderate northerly breeze), but still had a successful catch of 28 + (5). On 28th, Jerry's catch was 22 + (1), with a very similar mix to Andy although the Long-tailed Tit flock didn't return. On 29th Alan L, Ron and Lyndon were on site (Lyndon also wanting to check out solar panels), but after heavy rain for most of the night, it looks like overnight migration was curtailed, and they had a very poor catch of just 2 + (4).
The mix for these three sessions was Wren (1), Song Thrush 3, Robin 1 + (2), Dunnock 1 + (2), Chiffchaff 12 + (1), Blackcap 5, Goldcrest 9 + (1), Blue Tit 3 + (1), Great Tit 5, Long-tailed Tit 10 + (1), Nuthatch (1), Chaffinch 1, and Bullfinch 2. Although relatively few "tits" are being caught at the moment, its interesting that Great Tit seem to be the more common. given that they had a poorer breeding season (several chicks died post ringing).
With 274 birds ringed in September (just above our average for the last 10 years), our YTD becomes 2136.
Canada Goose 5266336 was ringed on 29 June 2014, and was shot at Wellington, Herefordshire on 17 September 2022 - 3002 days, 43 km, 59 degrees.
Canada Goose 5275837 was ringed on 26 June 2016, and the ring was found in the mud (about 15m below normal water level) at Llyn Celyn, Gwynedd on 18 September 2022 - (2275) days, 120 km, 345 degrees.
In June when reporting on the movement of a Great Tit, we mentioned an older control that had been rejected by the BTO - as "the movement was exceptional" and they suspected that the ring might have been misread (we were using a similar sequence ourselves). However, the capture remained in our database, and was re-submitted with historical data, and has now been accepted (as such movements are now more regular). So Great Tit T352419 was caught at the Lake on 19 November 2005, having been ringed (as a young female) at West Burton Power Station, Retford, Nottinghamshire on 20 August 2005 - 91 days, 231 km, 227 degrees.
Reed Warbler AVV1152 was ringed as a juvenile (at the jetty by JR) on 26 August 2022, and was caught at Chew Valley Lake, Bath & NE Somerset on 10 September 2022 - 15 days, 80 km, 147 degrees. Considering the relatively short distance between Chew and Llangorse, we have only had few Reed Warbler exchanges (less than two a decade) - two that were ringed there (1982 & 2015) and five that were ringed at Llangorse (1986, 1990, 2000, 2011 & 2017). Maybe the Bristol Channel acts as a bit of a barrier for direct movements?
Reed Warbler AVV0347 was ringed as a first year bird, in the Garden by JL & Madeline, on 19th September 2022 (see above for more details of catch). It was subsequently caught at Friar's Court Farm, Clanfield, Oxfordshire on the 2nd of October 2022. 13 days, 119 km, 102deg. The site very near the river Thames and interestingly the direction was close to being due east. Was this a young bird still exploring before returning next year to breed? Or a bird now heading for a narrower English channel crossing (Dover-Calais) having gone around the Bristol Channel? The speed of this recovery showing once again just how impressive the BTO DemOn data entry system is.
