Late Spring ... and Sedge controls

Ringing in April and the first 2 weeks of May on the Marshes produced  273 Sedge Warblers and 25 Reed Warblers.

The peak arrival and passage was between the 2nd - 7th May and the peak catch of 79 Sedge Warblers was on the 7th.

All of these birds have been to Africa between ringing and re-encounter at the Teifi Marshes this May. We would still like to get more re encounters from Ireland, to support our thoughts on the origins of a high proportion of our passage birds.

Of the 25 Reed Warblers caught by May 14th, 13 had been ringed by us in previous years, the oldest was ringed in 2016. A good start to our RAS project. 

Reed Warbler

House Sparrows, more from Andy soon but his first 3JJ of the season was caught and ringed on the 2nd May.

This male Linnet was caught at Mallard Pond in a reed bed net. We don't ring many on the Teifi Marshes. Chris has now visited and whoosh netted successfully at a new site along the north Pembs coast. We hope this will develop into a RAS, though maybe not as productive as our previous Linnet RAS site at Mwnt. (Edit by Chris 17/5/22: 64 new birds and 1 recapture in 4 visits starting 21/4/22).

Whose feet are these?? 

... a Moorhen caught on the Teifi Marshes at the end of a Sedge Warbler passage morning.

With the main passage of Sedge Warblers and White Wagtails over, our migration monitoring with the Mallard Pond reed bed nets has now finished for the Spring.

Returning Warblers....an update

Returning Warblers from April 9th to April 19th

The first Sedge Warbler was ringed on 13th April with another during the following week, we have now caught 8.

Sedge Warbler at Mallard pond

The first retrap Sedge Warbler from a previous year was originally ringed as an adult in May 2018 and seen again during the breeding season in 2019 and 2020 but not last year.

The first three Reed Warblers back, caught on 19th April were ringed in previous years, but two are amazing in the  lack of subsequent encounters..

S161817 ringed in August 2016 and not seen since

ABE2128 ringed May 2019 and seen in May 2020 and 21

AHA3217 ringed Aug 2017 and not seen since

Are these 2 or 3 birds site faithful stopover migrants ? We do have birds of some species that we suspect of this .... eg White Wagtails and Sedge Warblers. It is difficult to believe that during several breeding seasons we have missed these birds. We do ring quite regularly until July and intensively from July until October..

Other Warbler totals for 9-19th April 

Willow Warbler...22 new

Chiffchaff...12 new 

Blackcap.... 12 new

Grasshopper Warbler ... 2 new

Spring arrivals and returns

Late March into early April is a time when we start to see returning birds from previous years. 

A Blackcap was re-encountered on the 30th March that had been ringed in July 2017 and also seen in 2018 and 2019.

Although we haven't caught any new Cetti's Warblers yet this year we have re-encountered 4 from last year.

Cetti's Warbler

Four returning Chiffchaff  so far. Various histories with us..

One ringed last August - re trapped at the same site this March. One ringed in December, still with us - or now returned from a very late winter break, it's wing suggested it had been to the sun 

Two more that were originally ringed in 2020.

The number of returning and site faithful birds to the end of March can be clearly seen in the following table 

Species where birds have been re-encountered from previous years

Old birds of note are the 10 year old Great Spotted Woodpecker, a 7 year old Great Tit and Long-tailed tits and a Dunnock ringed in 2016.

It is always nice to see that the reed cut by a local thatcher has taken place - a cut is planned each year but for various reasons sometimes the cut doesn't take place. The cut area not only provides totally fresh Phragmites, but whilst the new growth is short, feeding for waders, pipits and in particular White Wagtails. We hope for some evening pre roost action any day...

We have caught 3 Curlew and 1 Teal over two evenings in the fading light, experimental at this stage and maybe a colour ring project with the Curlew, considering their current national profile. 

Teal

Some of the group are involved in nest recording and their season of monitoring is underway with the first Dipper chicks of the year ringed this week. Andrew has been exploring his local bridges and has found several Dipper nests.

House Sparrow RAS 2022

The 1st of April brought the start date for the second year of my House Sparrow RAS. With a good number of birds colour ringed in 2021, I successfully logged 35 different birds on the first morning for this year while having breakfast. Further observations over mid morning coffee took me up to 50 different birds and two further sessions on the 2nd of April took me up to 67 different individuals (40 male, 27 female). 

Despite my best effort last year, a reasonable number of 'older' birds still only have metal rings only and probably a similar number have no ring at all. The ideal situation would be to try to ring these birds but putting up mist nets in less than perfect conditions will mean high disturbance for low return as the birds will see the nets and simply avoid the garden. Walk in traps don't get used by adult birds in my garden so my best option is to focus on reading as many colour rings as possible while many birds are still coming to seed.  

N68 is a female that was ringed on the 22nd of February 2021. Being ringed in February, all that can be said about her is that she is from the 2020 breeding season or before.

40 of the birds sighted so far can be identified to a specific breeding season with the remaining being as N68. 33 of the birds sighted are over a year old. The majority of the remaining birds are known to be from the 2021 breeding season so technically speaking they are birds that have simply survived their first winter; many will of course breed this year. The oldest bird is known to be from the 2016 breeding season or before. Over time it should be possible to increase the proportion of specifically aged birds.

At this stage of the season many pairs in the garden are still in the process of nest building while adult birds that have lost their mate are trying to pair up or find a different nesting site. P05 (male from 2018 or earlier) seems to have lost his mate N90 (female from 2018 or earlier) and has moved to a new site. The box that he is clearing out was initially used by N01 (male) and N25 (female) last year and then by an unknown male and N25 for a later brood. Both N01 and N25 have not been seen for some time and the unknown male could not have been P05 so he may also have disappeared. Last year I noted that most of the early nesting attempts were made by incumbent adults with the offspring from the previous season mainly pairing and making nesting attempts later in the year.

The above female is not ringed. Most females have a bill colour that is dark brown containing varying amounts of dark buff-yellow/brown towards the base and in the lower mandible. This particular bird stands out amongst other females having a bill colour that is similar to a breeding season male.

Some early year thoughts ..

Most of our ringing so far this year has been focused on gardens and hilltops..

Arfon has managed to colour ring 3 new Willow Tits on Cors Caron already this year to help his RAS study..

Colour-ringed Willow Tit

The new moon phase has given our trainees the opportunity to experience lamping. With the mild winter there have been a low number of waders roosting on our study fields. Thom, Morgan, Yusef and Toni  have all ringed birds on the hilltops with us - several birds were ringed after their first time with the torch or net - and some variety ringed with Skylark, Snipe, Jack Snipe, Golden Plover as well as Woodcock 

This thermal image picture was taken on Frenni Fawr on the approach to a successful catch of a Golden Plover. The shapes in the distance are Crymych with the roof tops on the industrial estate showing intensely black on a cold night and the building showing white and warm is the sheltered accommodation by Crymych Surgery.

Arfon has now ringed 100 Woodcock on his study farms in North Carmarthenshire this winter. Totals for him so far this year are 31 Woodcock, 3 Golden Plover, 5 Snipe and 1 Jack Snipe. He caught a 2nd Woodcock with a very short bill at 51mm and this adult Woodcock with unmoulted outer primaries/

Unusual to see contrast in Woodcock primaries

In winter the main group training activity is garden ringing. 

Wendy's garden has proved very valuable for developing extraction skills as well as more general ageing and sexing, birds being caught in mist, potter or Whoosh nets, again some variety to learn to handle ..

Jackdaw caught in a Whoosh net

Handling some Starlings gives an ideal opportunity to teach different ageing and sexing characteristics.

Comparing tail covert shape

Having been ringing at this location for over 10 years many birds are caught from previous years. The table below shows the year of ringing from 2 gardens so far this year, both garden sites have ringing history including a Siskin RAS and now a CES study.

Initial ringing year Llechryd and Boncath gardens

The oldest retrap was a Great Spotted Woodpecker ringed on 20th December 2012 and also retrapped 2016 and 2020. 

We held our AGM on the 2nd February using Zoom again, most of the Group took part in the brief and relatively formal meeting. We had a look back at a successful year and discussed lots of positive ideas for the year ahead. We plan to have a more social and open meeting during early April.

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.

Siberian Chiffchaff, one of 4 ringed in 2020

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.

 A summary of unique bird encounters.

 

 

 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. 

Reed Buntings - Colin Dalton

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.

2021 Recoveries and Controls

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
