With only Bedfont and Woolley Firs operating this month, the total of 269 compares well with recent
Novembers.
No surprises in top species with Blue Tit on 105, Great Tit on 46 and Long-tailed Tit at 25, but 9 Redwing and 6 Gt. Spotted Woodpecker added to the total. Single records of Sparrowhawk, Chiffchaff, Firecrest, Bullfinch and Yellowhammer added interest.
We had some interesting returns from birds we'd ringed arriving this month - such foreign records can take a time to work their way to the BTO.
A Common Tern, ringed at Bedfont in July turned up in The Gambia (4,500km SSE) this month.
A female Reed Warbler, breeding at Bedfont this summer, was caught in the Bay of Biscay (750km S) in August.
A male Blackcap ringed in Wraysbury last summer, turned up in Belgium (330km ESE) this August and a Chiffchaff, we ringed last September also appeared on the continent, near Calais, this October.
A Redwing, ringed at Stanwellmoor Gravel Pits in October turned up in Devon (214km WSE) this month too.
And two of our Blue Tit chicks from this year's broods, one each from Woolley Firs and Bedfont turned up at Queen Mary Reservoir on the same day this October.

October - The Goldcrests have arrived
Despite the unhelpful weather, a few sessions were possible on calmer days and the month total did reach 418.
October is always variable depending on Redpoll and Meadow Pipit flocks, so this is quite a healthy total.
A Stonechat at Stanwellmoor was the most unusual species. Goldcrest poured into all sites and tied for first place with Blue Tit at 74; Meadow Pipit followed on 56 with Long-tailed Tit on 35 and Redwing on 32.
Blackcap and Chiffchaff both managed 22 and there were small numbers of finch including four Lesser Redpoll.

September - high catches kick-off the month but weather stops the migration survey
A rather frustrating month with only Bedfont, Wraysbury and Tythebarns in operation and the weather being uncooperative after 22nd.
The sessions that were held were very productive with Wraysbury processing over 200 on each of two sessions and Bedfont 40-50, so the total of 737 would have been much higher with better weather.
Blackcap was top species at 397 (54% of the total) with Chiffchaff at 112 and Blue Tit trailing at 52. Noteworthy were 6 Lesser Whitethroat, 7 Whitethroat and 7 Willow Warblers; the only Sedge Warbler ringed, was at Bedfont.

August - Highest numbers since 2015
August gave a magnificent total of 1,513 new birds of 32 species; the highest since 1,590 in 2015.
The top four species now (and in 2015) were 628 Blackcap (417), 208 Whitethroat (241), 150 Chiffchaff (123) and 123 Garden Warbler (179).
Among the less-frequent warblers were 21 Willow Warbler (33), 18 Lesser Whitethroat (22) and 4 Sedge Warbler (22). This follows the national trend for Willow Warblers where numbers are falling in the south of England; whereas the fall in Sedge Warbler, while may be impacted by habitat degradation, requires further study to understand.
Highlights this month were 4 Tree Pipit (Stanwellmoor and Wraysbury) and a Redstart at Wraysbury.
Recoveries included a Common Tern we colour-ringed at Bedfont Lakes in July 2016, sighted, this month, at 138km northwards at Rutland Water.

July - Nightingale returns to Wraysbury
 |
| Nightingale (Chris & Denise Lamsdell) |
Blackcap was top species with 267 with Whitethroat some way behind at 105 and Blue Tit on 85. But among the 546 new warblers there was only one Lesser Whitethroat (Bedfont) and one Willow Warbler (Wraysbury).
Other less-frequently ringed species this month were a Sand Martin (Stanwellmoor), 15 Swallow, a Jackdaw, 19 Starling and 7 House Sparrow.
June - Red Kite visit RRG
Typical – we wait sixteen months for a new species for the group list then two come along together!
Three Red Kites were attracted to the Iver Heath garden, together with a Lesser Black-backed Gull.
Statistically, LBBG was already on the list on the basis of some holiday ringing in Cornwall over 40 years ago, but this is the first within the Runnymede area. Also unusual were four Lapwing pulli at Langley Vale, and altogether the July total was 378 new birds of 32 species.
Juveniles swelled the catches with Blackcap the most numerous at 89, Whitethroat at 41 and Chiffchaff at 30.

May - Little Ringed Plover returns
A productive month with the total of 331 new birds of 27 species; well up to expectations.
The number of pulli ringed, at 112, were lower than usual making the number of free-flying birds ringed is actually the highest since 2016.
Little Ringed Plover made a welcome return to the list (the last ones ringed by the group was in 2010) and Blue Tit (81) and Great Tit (43) led the species – but most were boxlings.
Otherwise, Long-tailed Tit was top at 35 followed by Robin on 31 and Whitethroat on 29th.
