2021 ringing totals and into 2022

2021 was a successful year for the Teifi Ringing Group with excellent results for our established studies and some good ringing plans to help the development of new studies, projects and training. We finished 2021 with 6,719 birds ringed of 67 species

 

Sedge Warbler at Mallard Pond

Again a drop in the species ringed compared with  72 species in 2020 and 78 species in 2019. The total number ringed has declined too, but by less than 10%. There are several factors which have affected these totals including - the effect of movement restrictions, a poor breeding season, the activities of  Group ringers elsewhere, in  particular Skokholm Bird Observatory where we have an excellent working relationship and visits here often involve ringers from the Group and South Wales.

New standard searches in our BTO database, DemOn allow for different ways of looking at totals. Here we show the total number of birds ringed plus those recaught or resighted from previous years.

 Resighting colour rings by photographers on the Teifi Marshes has made a significant contribution to our RAS project and knowledge of Reed Buntings from previous years.

During the year we have written 16 blog posts, mostly monthly highlights, but also major posts from Andy updating his House Sparrow RAS and colour-ring project. Other posts of interest include projects, recoveries and visits to Skokholm Bird Observatory.

The map illustrates some of the movements included in the table above.

Each movement was detailed in blogs during the year as we received them

We are very grateful to Stephen Vickers for the mapping apps he has created.  The ability to to use the data directly from DemOn to produce maps like the above is invaluable.

 

Some variances in the species ringing totals worth mentioning....(2021/2020)

Sedge Warbler - 387/193 and Reed Warbler 265/141 a result of return to near normal  study activities on the Marshes

Redwing - 333/ 213 more focus on late autumn ringing helped by our interest in catching the increasing number of Chiffchaffs later in the morning using the same nets and location.

Willow Tit - 22/1 new focus, colour-ringing and new RAS

Dipper 36/4 , Pied Flycatcher 72/28 , Barn Owl 7/3 are all increases due to the increased focus of several of the Group in nest recording, often in projects supported by Pembrokeshire Coast National Park, The Woodland Trust and The Wildlife Trust of South and West Wales at some of their key site in North Pembs

Gwaun Valley nest box

Leach's Petrel,  Siberian (tristis) Chiffchaff, are species/sub-species ringed rarely by the Group and Black-tailed Godwit was a new species for the Group.

Black-tailed Godwit

 

For the fans of the Teifi Kingfishers - 

Kingfisher - 10/10 no difference in the total for the last 2 years, 10 different individual Kingfishers on the Teifi Marshes.

As we start 2022 we are hoping for a year relatively free of movement restrictions. We have a great group of  newer trainees, Thom, Yusef, Dan, and Morgan to help us develop our sites and projects as they develop their ringing and project skills.

Yusef measuring a Woodcock ring

Our main site will continue to be the Teifi Marshes Nature Reserve and we thank the Wildlife Trust of South and West Wales for access and support - particularly Nathan Walton. We regularly ring at 3 seperate sites on the Marshes and we are developing a fourth. More on "wilti and 18 acres " as we plan and develop our activities at the site.

Willow Tit - Teifi Marshes

 Studies as we enter 2022 and the future.......

CES - Llechryd, and RAS studies on House Sparrow, Reed Bunting, Reed Warbler and Willow Tit will continue.  Recently we have finished our RAS studies on Linnets and Siskins - we may restart both depending on sites and bird numbers. In both the Reed Bunting and Willow Tit  RAS studies we also add colour-rings. This is particularly valuable with the Reed Buntings on the Teifi Marshes reserve - a great opportunity involve visitors to the reserve in our studies, and successful !    We think we will see another increase in nest recording and pulli ringing. Several of the Group like to specialize in this valuable area of study in the breeding season.

 January...

January has started with poor weather for mist netting but other methods were used including the purchase and use of new traps and lamping. 

Some ringing results for January in the next post..

 

Before we go a memory from 10 years ago !!

December on hills and in gardens

As December draws to a close with a spell of wet and windy weather offering few opportunities for ringing, we look back at the last few weeks.

The third most frequently encountered species was Woodcock. No surprise as lamping them at night is possible in windy weather. Arfon has been busy on his local upland sites near Ffarmers including 6 birds ringed in previous years. Woodcock are very faithful to their wintering sites as this example on a farm near Boncath shows.

EZ73664 was ringed there on 14th November 2020 and we re-encountered it this year on the 2nd December very close to its original ringing location. Every time a Woodcock is caught we record the GPS and plot them on Google Earth

To give an example of the scale of our historic data these are the Woodcock caught over the last 10 years in just 6 fields

Other species ringed at night this month included Snipe, Jack Snipe, Fieldfare, Golden Plover, Skylark, Redwing and Meadow Pipit. We plan to introduce our new trainees to lamping over the next few weeks.

Starlings were the most frequently ringed species, nearly all caught in various traps rather than mist nets. The one subsequent encounter listed below was a bird with a Belgian ring in Andy's garden. We are still waiting for details from the Belgian ringing scheme.

December 2021 totals in gardens, farms and Teifi Marshes

Three of the group have recently bought these walk in traps from Jed Andrews, South West Norfolk Ringing Group. Pictured here as we all excitedly un packed the trap when it was delivered during a ringing session.

Thanks to Jed for designing and supplying these. Although currently being used in gardens we plan to use them for a wider range of species soon.

Looking at the table of captures it can be seen that there is a high proportion of subsequent encounters. Most of the Reed Buntings and many of the House Sparrows are re-sightings of colour ringed birds showing the importance of this work. We are grateful to the valuable re-sightings by photographers on the Teifi Marshes and would like to thank Colin Dalton and Tommy Evans in particular

Warblers and variety in November

November started with a good session at our site in the Pentood part of the Teifi Marshes with a very late Reed Warbler and unusually for the site, 2 Stonechat.

On the 10th, a Siberian Chiffchaff was ringed in Pentood, to be followed by 3 further birds on the 16th and 17th at our River View Point site on the Teifi Marshes.

Siberian Chiffchaff

A look back into the Group's history and our first and only previous Siberian Chiffchaff on 15th October 2015   "An interesting Chiffchaff"

Our catching of Siberian (tristis) Chiffchaffs is part of a widespread arrival across the southwest this autumn - we have caught  10 collybita  and 4 fulvescens type Chiffchaffs this month too.

Recent news of Chiffchaff  KCC988 ...

Subsequent encounter Skokholm Island 20/09/2021 42 days 61km SW

On the 5th November this Sparrowhawk and two Kingfishers amongst the 77 Redwings caught.

Sparrowhawk

By the end of the month 260 Redwings had been ringed, mainly on the Teifi Marshes but also in a young woodland in Llechryd.

A good number of Crests have been ringed this month, 58 Goldcrests and 1 Firecrest on the 17th.

Firecrest

The Group have captured 25 Firecrests in the last 10 years including one from Belgium, 16 of them in November.

But where are our Firecrests and Yellow-browed Warblers this year ?? Perhaps December will provide some late season birds.....

Starlings have been seen in increasing numbers over the last few weeks

241 ringed, mainly by Andy near Llandysul. One Starling that Andy has caught twice this month in his garden had been ringed in Lithuania.

Starling KE14864  

Ringed by the Lithuanian Ringing Centre at Silutes, Lithuania 16/06/2020

Subsequent encounter Bancyffordd, Carmarthenshire  29/11/2021   531 days 1717 km WSW 

As it was ringed in June it is likely that  Lithuania was it's  breeding area.

Starling KE14864

Not many G rings are used at our garden ringing sites..

So this 2cy Buzzard was quite an achievement in Chris's whoosh net- slightly different from the Corvids including a few Jays caught recently.

Buzzard

To end November, this Woodcock with an abnormally short bill was ringed by Arfon.

It measured just 57 mm (bill to skull), presumably a healthy juvenile arriving in mid Wales to winter from it's natal area much further east.

A Leach's to start October ....

The weather in October was mostly tricky for mist netting but here is a round up of what the Group have been doing.

The highlight of the month was a species not often ringed in Wales. The night after a storm on the 5th October, a Leach's Petrel was found stranded ashore in Fishguard Harbour. 20 had been counted passing Strumble Head that day. It was handed to Sea Trust Wales and kept at the Ocean Lab where we took biometrics and ringed it. 

It was a healthy bird weighing 38.8g. It was released back to sea that night. See Cliff Benson's post on PembsBirds

Leach's Petrel forked tail

Another Leach's Petrel had been ringed by the Group on 5th September 2019 along with some stranded Manx Shearwaters. See PembsBirds blog Sept 2019 for details.

Most of the ringing was on the Teifi Marshes and in gardens. Just 302 birds ringed during the month.

Redwing started to arrive in October and were the most frequently encountered bird with 63 ringed, mostly in dusk roosts.

Although 27 different species were ringed there were very few of each compared to previous autumns.

Subsequently encountered  Longis Bay, Alderney 04/09/2021 21 days 316km 

Now November is here, we have some of the following ringing to plan ...

Reed Buntings - Potter traps, Redwings - pre and post roost, Finch ringing - likely various garden sites, House Sparrow project - Andy's, Willow Tit project - Arfon, Woodcock - moonless nights, Forestry sites - nice weather !

One of the Group, Molly is currently in USA working at Klamath Bird Obs. A paper based on her recent  MSc at Bangor University has been published in BTO's Bird Study

Some thoughts for 2022...

Most of the Group are visiting Skokholm Bird Observatory next year, the first visit planned for the end of April.

September update

September started with calm weather and the chance to open nets on several occasions but as the month went on we struggled to find suitable weather windows. The September totals below are from all of the Group sites.

male Blackcap

Blackcaps featured well this year, no surprise in our scrubby site near the river on the Teifi Marshes  and a considerable increase on last year's 40 ringed but change in effort is the main reason

September totals

Andy's House Sparrow colour ringing aids the RAS study and continues to deliver new and subsequent sightings - see his blogs ...Bancyffordd RAS summary 2021   and  House Sparrow April summary

With ringing sites becoming established in upland conifer plantations some more variety in species should be possible in years to come. This is building on long running studies of the Preseli forests by Paddy Jenks. Karen started nicely by ringing a Firecrest in Ty Rhyg forest. Meadow Pipits were an upland species too at a site on Dinas Mountain. 

A Robin from the Midlands shows a nice South West  seasonal  movement, and I would like to think the same with the appearance of  un ringed Cettis Warblers this September - we have had movements from West Wales to middle England this time of year.

Goldfinches are continuing to  become the norm  ringing at feeders and produce recoveries across the UK and abroad. The number seen has been increasing over the last few weeks and this one ringed in winter in France was in Wendy's garden in Llechryd this month

Goldfinch  8338252

Ringed Bazoges-en-Pareds, Vendee 04/01/2019

Re-encountered Llechryd, Ceredigion 18/09/2021 988 days 660 km NNW

It was an adult in wing moult

We took advantage of tides and weather, good to get some Dunlin and Ringed Plover ringed, we hope to carry on with catching small numbers of Ringed Plover over the winter months. 

Most birds we catch at this time of year are juveniles. The adults we do catch stand out immediately by the wear on the feathers, particularly primary tips as shown on this Dunlin.

Some of the group have been collecting specimens for the UK Flat Fly project co-ordinated by Denise Wawman. This is looking at the distribution of flat flies around the UK. For the last few months we have had specimen pots ready and waiting for a flat fly to spring out from a birds feathers and catch it quickly before it dives towards the ringers hair!  The Flat Fly Family are ectoparasites that feed on blood of birds and mammals. Those that occur on birds don't feed on humans. The flatness of flat flies allows them to slide between feathers to get at the skin of the host, where they plunge a hypodermic-like mouthpart through the skin to suck up blood. 

Flat Fly collecting

The bulk of the specimens have been collected by Andy from the many House Sparrows he rings. Other species with flat flies have included Blackbird, Great Spotted Woodpecker, Goldfinch. Song Thrush and Goldcrest. 

October has started with unfavourable weather for ringing but we are optimistic for the next week having studied the weather forecast.

Early Autumn on the Teifi Marshes, Poppit and Skokholm

Our main activities at this time of year are mist netting on the Teifi Marshes and Andy's continuing work with House Sparrows. If you missed his last blog it is well worth a read particularly for anyone who catches House Sparrows with some tips regarding ageing.

Bancyffordd House Sparrow RAS summary

In the first couple of weeks of September, over 250 birds have been encountered on the two sites on the Teifi Marshes. Some of the species caught are mentioned below...

Sparrowhawks are often seen over the marshes but not many have been ringed on the reserve but this young male was ringed this month at our site near the river.

Reed Warbler numbers seem to be as expected with 21 birds ringed and an old one re - encountered that was ringed in 2014. The number of adult Reed Warblers re- encountered from previous years for our RAS project is now slightly above average at 42. 

Sedge Warblers are slowing down with just 31 ringed so far this month. 

One that we ringed on migration was re-encountered by another ringer 3 days later in Dorset, a site that we have exchanged several birds with over the years.

AJN6891 ringed Teifi Marshes, Ceredigion 23/08/2021

Re - encountered Squire's Down, Dorset 26/08/2021 3 days 201 km SE by T Squires

Blackcaps have been the main catch in the last week with over 70 ringed this month. A fat 6 Garden Warbler was a hefty 22.4g. Just 1 Grasshopper Warbler is lower than usual but other migration sites eg Cornwall and Wiltshire have reported many more than usual.

The new moon and very high tides meant that we were able to catch some waders feeding on Poppit beach. Dunlin and Ringed Plover were ringed and a new species, an adult Black-tailed Godwit.

The  size of bill and the moult limit in the primaries are features that lead us to this being an adult male islandica Black-tailed Godwit.

Some of the group experienced a trip to Skokholm at the beginning of the month along with two trainees from Gower Ringing Group. Here is a mention of our visit on the Skokholm blog 

Over 500 birds were processed during the weekend. The main focus was ringing Manx Shearwater fledglings at night and different catching techniques for passerines including spring traps and walk in Pipit traps

Ringing Manx Shearwaters

Some Storm Petrel chicks were ringed along with many Willow Warblers, 3 Pipit species and Pied and Spotted Flycatchers

And not forgetting the Wryneck, a record year for them on Skokholm.

Bancyffordd HOUSE SPARROW RAS summary for 2021

 

2020 was the trial year for the House Sparrow RAS in Bancyffordd, it proved successful and so the project was registered with the BTO. Colour ringing of individuals commenced during October that year. During 2021 the RAS has been completed between the dates of the 1^st April until the 31^st August and 117 adult birds were recorded. Over the same period 300 juveniles have been ringed for the second year in succession. Well over 450 birds have now been colour ringed but with only two years of data the project remains in its infancy.

Because of the ease with which colour ringed individuals can be identified, it is not surprising that the number of adult birds recorded this year has been greater than the total for 2020. Sighting data suggest that there have been at least 60 pairs that have had either single or multiple breeding attempts throughout the summer. During this period, some adult birds have seemingly disappeared from the population but many known juveniles from 2020 have bred for the first time. Leading up to 2020, there was no focussed effort to ring House Sparrows in our garden and so annual totals varied considerably. the age structure of the adults seen during 2021 is as follows:

From a nest in 2016 or earlier                  2 (both males)

From a nest in 2017 or earlier                  6

From the 2017 breeding season            1

From a nest in 2018 or earlier                  6

From a nest in 2019 or earlier                 13

From the 2019 breeding season             2 (both were from garden nest boxes)

From the 2020 breeding season             32 (1 of which was from a garden nest box)

From a nest in 2020 or earlier                  55

All free flying nest box chicks have been colour ringed when trapped during 2021 and it is planned to continue to do this in future years which should mean that the 32 known age birds seen this year should increase substantially in 2022. All being well, it should be possible to start looking at how many of the 3JJ birds (most likely to have been from a nest in the village) remain in the village to continue the village colony.

In August, two of the colour ringed birds have been photographed in gardens in Ceredigion, one in Llandysul (2.8km) and the other in Adpar (11.0km). Both birds were from the 2021 breeding season. It is most likely that the birds were from the Bancyffordd breeding colony, but this is not proven. If one assumes that late summer/autumn dispersal from the colony occurs, then it is also fair to assume that birds are recruited into the Bancyffordd population from external sources. It seems to be clear that individuals of all ages fly freely within the colony but at what distance this ‘freedom’ is curtailed is not obvious as adult birds from a satellite colony seem somewhat reluctant to travel the short distance of 280m from their nesting area to the centre of the village.

This year I have noticed a lack pale feathering in juvenile birds and the near absence of random white feathers in adult birds. Many of the juveniles have had growth bars which isn’t too surprising given the periods of poor weather during the breeding season. Often juvenile birds have been host to the relatively large flat fly O.avicularia. Even though some birds have multiple flies, I have not noticed any apparent ill health (e.g., low mass, reduced pectoral muscle) as a result their infestation. More recently I have noticed large ticks on some birds; these seem to be more of a concern to the welfare of the birds as several of the hosts appear to be in poor condition.

Another topic I have spent some time looking at is the shape of secondary feathers. As moult progresses, it becomes increasingly challenging to age some birds, especially females. The following couple of photographs may be of use to those interested.

           

This bird is an adult female undergoing complete moult. One of the primary feathers has been replaced with a white feather. Four old secondaries remain and, if the condition is reasonable, I think these can be used to help age female House Sparrows later in the moult cycle (see next photo). 

                       

This is an age 3 male undergoing its first full moult. The first secondary has been replaced and the end shape of the new feather is notched compared to the inner juvenile feathers that are quite rounded in comparison. I have not seen any juvenile feathers that are notched.

The next few months will be spent trying to catch some of the numerous individuals (both adults with and without metal rings and young) that have avoided my bests efforts to date, many of these will end up as birds of no specific age.
