Early winter - update

Now that the 2022 ringing stats have been published by the BTO, a look at some of the numbers for WALES

20 % of all new Reed Warblers

40% of all new Sedge Warblers

50% of all new Reed Buntings

... in WALES were ringed by the TRG...mostly on the Teifi Marshes. The importance of this cross county site for population studies is immense. 

91% of all new Linnets in Wales were ringed at Chris's Whoosh net RAS study site.

26% of all new House Sparrows in Wales were ringed at Andy's RAS study site

With the REEWA,  REEBU,  LINNE and HOUSP RAS projects and the colour- ringing of REEBUS and HOUSP...

Quite an achievement...👍

A few pieces to update our results whilst some of us have been away...

Controls and movements....

During a short session in Wendy's Llechryd garden to sort nets after being away, a Goldfinch with a French ring was caught.

Weather continues to hamper our ringing efforts. A couple of small Redwing roost catches this month has increased our total since their return to 149 including 1 retrap from a previous year, 1 same year retrap and a control from Holland.

Thanks to Nathan and the Thursday work party on the Teifi Marshes for some management work in our net rides. 

On a tidying up session this week we caught the first December Firecrest and only the 6th December Chiffchaff

Andy's total of 108 Greenfinch  since the beginning of September is very impressive and maybe showing signs of an increasing local population, or maybe of migrants ..... 

The fields are saturated but Arfon has had success on a few nights of lamping, teaching two of our trainees new skills

3 retrap Woodcock from last year and 39 new plus 11 Golden Plover and a Snipe.

With a favourable moon we hope to visit  4  more nightime survey and lamping sites over the next 10 days. Day time ringing when ever the weather allows.
