Dunlin, Swallows, Sedgies...

A 930pm view of the beach ....not the darkest of nights to lamp for waders. Two visits and 5 Dunlin of the few birds present ringed, we are off to a start for the season..

Our first Dunlin, though our Ringed Plovers are of much more value to ring with far fewer caught as they are difficult to cannon net.
One attempt with the 60' foot Aquatic net did produce twenty Swallows, a couple of acros and our first wagtails of the season. Yesterday we managed a typical early session in the Mallard Run nets. We were not surprised that we didn't catch an Aquatic,  42 new Sedge Warblers was a good total though.
A new Kingfisher and more new and retrap Reed Buntings for our RAS adding to the success of the session too.

Rarities (for us) in the Reed-bed

Preceding the Buzzard !! in a Pentood mist net yesterday, - see post below, a couple of other goodies in the nets on Friday...
This first year male Redstart, an annual for us, but not usually in the phragmites.

In the same net round, this juvenile House Sparrow, our first capture on the reserve though we do ring our garden populations.

Otherwise, not as busy as we would have hoped, with no major acro movement yet...just 21 new Sedge and 24 new Reed Warblers. A couple of retrap Cetti's Warblers and two more Reed Buntings colour-ringed to help our RAS project along.

One Of These Days....

Only the other day as we were walking off the marshes, I said to Rich "that Buzzard's been hanging around those bushes since the springtime, one of these days we'll find it in a net".

It doesn't take a genius to guess what happened today; I returned from a round of the reedbed nets to find Karen standing there looking like the cat that got the cream, with this beauty bagged inside her tee-shirt. (Sensibly, she'd taken it off first).


This was the second mist-netted Buzzard I've encountered, in both cases they've been lying on the ground holding onto the bottom shelf of the net with their talons. I vividly recall extracting the first of these myself and having a supposedly more important ringer take over and do the honours, so there was no question but that Karen would get to ring this one.

Note the seemingly random mixture of old and new feathers on the back and in the wings. Neither generation of tail feathers were of the juvenile type illustrated in Baker, and there were three generations of primaries, so this would appear to be at least a 2nd-summer bird.

Apart from that excitement it was a slow-ish morning, with only three more juvenile Whitethroats worthy of mention, and an early finish as the wind got stronger.

CES 10 today as Bertha cancelled our ringing course...

With a ringing course planned for this weekend, we have been watching the weather forecasts obsessively for the last week. It became increasingly concerning that the weather could be dire and a lot of the weekend spent looking at the rain.
Sadly we had to make the decision with Kelvin, BTO Wales, to cancel it.
We had been saving our CES 10 for the course participants but without the course we went ahead and did it today. It was hot and sunny so the birds slowed down as the temperature rose but we ended the morning having ringed 50 new birds and 16 retraps.
Reed Warblers made up the bulk of the catch again. Nice to ring a juvenile Whitethroat, only the second this year.
A Woodpigeon was the first we  have caught in a CES session. A chance for Ryan, our new trainee, to ring his first non-passerine and learn a bit about Woodpigeon moult, a species that has 11 primaries. The contrast between the old and new primaries can be seen here.

As autumn migration starts, a look back at July in the reed bed...

As August begins we look forward to as many early mornings in the Teifi Marsh reed bed as the weather allows. Mornings often start misty and cool with a soaking from condensation on the reeds.

But end a couple of hours later with the scene transformed by the warmth of the Summer sun
The reserve is an important stopover for migrant birds particularly Sedge and Reed Warblers. Since 2010 we have been putting extra effort into monitoring autumn migration and wrote a paper in 2011 on our findings funded by a grant for the Welsh Ornithological Society. In 2010 we caught 2 Aquatic Warblers as part of this constant effort.
With all of the July data for the Teifi Marsh reserve entered into IPMR we have been playing with the data to see how the month went in the Ceredigion part of the reserve between Mallard and Heron Hides.
368 birds were ringed and 143 retraps many of which were site faithful birds ringed in previous years.
Of those 368, 102 were Sedge Warblers, 95 Reed Warblers and 26 Reed Buntings.
On the reserve as a whole we are pleased with the number of returning Reed Warblers from previous years - now up to 57. Another 28 adults have been ringed and so far 146 juveniles.
In July 2013 we only ringed 31 juveniles.
Once we get to the end of migration we will compare numbers with previous years.
With each Reed Bunting being entered into our colour ringing project there will be plenty of birds for photographers visiting the reserve to resight for us.
The juveniles being caught at the moment are well into their post-juvenile moult.
This one today was moulting all of its greater coverts and central tail feathers
showing why ageing after this first moult can be difficult with no contrast to be found in the greater coverts.
Next weekend we are co-hosting a BTO ringing course. We are looking forward to welcoming 10 participants and several assessors from around the country. We are keeping our fingers crossed for the weather and really hope that the rainy bits of the forecast are wrong!
Ex tropical storm Bertha could bring heavy rain and gales on Sunday

A Stormie control.........returning to the Bay !!

A second "summering faithful " Storm Petrel was controlled on Sunday night - 27th July, this time near Aberystwyth by Tony Cross.
We ringed this bird on the 22nd July 2012 at our Mwnt site.....c36 miles to the south along the coast.

Site faithful summer visitors.........with no known breeding along the coast.....??  Or....??
Bardsey and the Pembs islands are the nearest known breeding sites.

We tried at a new site for us last night, Ceibwr, a site between Strumble Head and Mwnt - no birds caught or seen.

CES 9, Reed Warblers headline again

A good day for Reed Warblers again on the Teifi Marsh with 41 caught out of a total of 88 birds. Juveniles for the whole reserve are now up to 122 so far this breeding season. 54 adults ringed in previous years have been retrapped this year. In a county that had no breeding Reed Warblers until the '70's  this is excellent news.

Always nice to catch a Kingfisher as this is species is the logo of our group. 33 have been ringed on the reserve since 2008.

A good opportunity to revise the aging and sexing...

All the Tit species and Chaffinches were down or absent compared to previous years. Plenty in all of our gardens though, particularly abundant are juvenile Great Tits and Chaffinches.
