January 2019 - Norway & Gibraltar recoveries received

204 new birds of 20 species got the year off to a good start for the hardy teams that ventured out.

Unsurprisingly, Blue and Great Tit topped the list with 85 and 30 each, but Goldcrest and Long-tailed Tit tied for third on 14.

Nice species to get on the list were 3 Meadow Pipit, a Fieldfare, Cetti’s Warbler, Blackcap and Lesser Redpoll. Details of a number of recoveries were received from the BTO. Notably, the Redwing from December 2018 ringed in 908km away in Rogaland, Norway in the autumn of 2017 and a Blackcap, ringed by the group at Minet last August and recaptured 1,754km away in Gibraltar last August.

Norwegian Redwing - December 2018

Ringing sessions were hampered by unsettled weather but most sites managed at least one outing although catches were often low.

The total of over 193 new birds of 20 species brought some surprises with Redwing ringed at most sites and their total of 33 put them in second place after Blue Tit on 39.

Other good December species were a Meadow Pipit at Woolley Firs, a Blackcap at Iver Heath and 3 Chiffchaff, at Bedfont and Wraysbury. Finches and buntings were hard to come by with only 7 ringed in the period.

There were controls of Cetti’s Warbler at Stanwellmoor and a Norwegian Redwing which are awaiting ringing details.

Cetti's Warbler & Chiffchaff movements - November 2018

A quiet month with only 138 birds of 16 species ringed, 131 being at Woolley Firs targeting Blue Tits for the BTO post-juvenile moult survey.

Needless to say, Blue Tits were the top species at 64 but there were also 5 Collared Doves at Tythebarns and 5 Redwing and a Mistle Thrush at Woolley Firs. Mistle Thrush is actually our rarest thrush at Group sites, the last being at Tythebarns in April 2015.

A control of a Wraysbury-ringed Cetti’s Warbler in 2018 was the first long-distance movement of a group-ringed bird, recapture at Titchfield Haven, Hampshire; and a Chiffchaff made a rapid journey to the Portsmouth from Wraysbury taking just 5 days in September/October of 2018.

Redwing recovered north of Arctic Circle - October 2018

A rather quiet month with only 258 birds ringed – our lowest October total for 10 years. Bedfont managed two sessions with a third rained off, but added Kingfisher. Elsewhere, top species was Lesser Redpoll at 65 followed by 20 Goldcrest, 17 Meadow Pipit, and 15 Redwing.

There were recoveries of rapid Blackcap controls from both Cambridgeshire (after 9 days) and Derbyshire (after 10 days). But by far the most interesting recovery was a Redwing, ringed by RRG at Black Park CP in November last year and found, this month, near Sodankylä, Finland; 2,300km north-east and well north of the Arctic Circle.

Fair weather for bird ringing - September 2018

Grey Wagtail
Good weather conditions had ringing take place on most weekends and some mid-week
sessions too.

The result was the highest September total, 1206, since 2013 (1397). Blackcap comprised nearly 40%
of the catch at 473, followed by Chiffchaff, nearly 18%, at 216.

Highlights were a Grey Wagtail at Surrey (rarely caught at our sites), 50 House Martins at Wraysbury and 27 Willow Warblers. Other warblers tailed away with few after mid-month, but small numbers of finches spoke of things to come.

CES birds on the up - August 2018

Despite early season worries about low catches on CES, both Bedfont and Wraysbury
improved later and are heading for reasonable totals.

Overall, August saw 982 new birds ringed, rather more than 2017 (945) and well up on 2016 (764). The 34 species included: pulli of Barn Owl and Swallow and there were captures of Sparrowhawk, Jay, Magpie and three Jackdaw among larger species.

Five House Martin and 13 Meadow Pipit came from Stanwellmoor and Willow Warbler were up to 56 after only 24 last year. Blackcap was top species at 299 followed by Whitethroat at 153 and Garden Warbler at 84. Reed Warbler had good numbers through Stanwellmoor raising them to 4th place at 71.

July 2018 - bird numbers down on recent years

A poor month for captures with a total of 482 new birds, when recent Julys have been over 700.

Low catches continued on CES sessions and one of the three planned Wraysbury sessions was postponed till August, but whether the low numbers are due to the hot weather, or to a cold spring, or to low productivity, awaits analysis.

The top species was Blackcap at 90, closely followed by Reed Warbler on 85. Only 20 Chiffchaff were ringed. Kingfishers have had a difficult year so it was good to have singles at Bedfont and Wraysbury, and Stanwellmoor had some success with all three hirundines.

Other pleasing records this month were 3 juvenile Meadow Pipit at Stanwellmoor, 4 Cetti’s Warbler (Bedfont, Wraysbury and Stanwellmoor) and a House Sparrow at Bedfont South Side.
