Waders and Farmland Birds

With the wind whipping up overnight my plan to mist net some owls at my farmland bird winter ringing site yesterday morning (25th October) went out the window so I decided to take a spin around the turf lawns along Lough Foyle instead to try for some waders.

On arrival @ 05.45 there was very little about and the sky was starting to break in the east. I switched on the ‘Killer Redshank’ call and a few birds started to appear. I dazzled a couple of Dunlin and a Jack Snipe before a Little Stint dropped in. It gave me the run around for five minutes and it was getting very bright but I tried standing still beside the tape and it walked right up to me! 

Little Stint

This was the first Little Stint ringed in Northern Ireland since at least 1977, possibly the second ever following one at Copeland Bird Observatory in 1963. Jack Snipe are also irregularly ringed with this one being just the 26th ringed since 1977 in Northern Ireland. 

Jack Snipe

The previous visit with mist nets & dazzling on the 21st September produced 25 Dunlin, 1 Ringed Plover & 1 Redshank. 

Ringed Plover

After the waders I nipped over to our Myroe farmland bird site to open up the net rides for the winter. There were lots of thrushes buzzing through the hedgerows which were loaded with berries but it was too windy for nets along there. The lure of the site are the heaps of dumped seed from local farmers which attracts a nice range of species later in the winter & a disgusting number of 🐀 rats🐀 but I’m hoping these might attract birds of prey.

With good numbers around I got a little distracted and put up 2 sheltered nets, once the rides were cleared and caught 49 new & 1 retrap.

Blackbird -  1

Blue Tit - 7

Chaffinch -  4

Dunnock -  1

Great Tit -  2 (1)

Grey Wagtail -  1

Lesser Redpoll - 2

Linnet  - 1

Pied Wagtail - 1

Robin - 4

Tree Sparrow - 24

Wren - 1

Tree Sparrow

The two wagtail species were a bit of a surprise but there is a sheugh just beside one of the nets and may add another dimension to ringing at the site. The 24 Tree Sparrows was our largest catch yet and I would estimate there were around 100 present. One of three Buzzards present managed to fly through a net and leave a big hole.

I then received a text from Theo Campbell to say that a Cattle Egret was back on my home turf of the Bann Estuary, so a rapid take down was executed & I was watching the bird within 30 mins. This was the 233rd bird species ever recorded in the Bann Estuary & a lifer for me.

All in all a very productive morning and a promising start to the winter ringing.

I will back track with some updates from the years ringing... but it may take a while!

Bann Estuary Waders 2019

As usual we've struggled to match up the ideal tides that fall over a couple of days every two weeks after sunset, with some ideal weather and availability of a suitable team (some of the older guys play bowls 😅) but we did succeed twice.
The first of these visits was on the 7th of August with myself, John, Abbie, Rich K and John S. The catch was steady over the few hours of darkness in the three nets and produced a new species for us - Greenshank.
In the end we managed to catch 3 Greenshank, 18 Dunlin and 14 Redshank plus a BTO control.

Greenshank

In 2018 there were only 18 Greenshank caught across the UK and Ireland and between 1952-2018 there were just 53 trapped across Ireland, 12 in Northern Ireland since 1977, so a very good catch indeed. Interestingly there were 7/8 present and we did try a range of their own calls but they only came into the mixed tape to roost.

Knot

The next session was two weeks later on the 21st of August, again with help from Abbie & Rich supported by Ken. We reduced the number of nets down to a single 12mx12m V net set and had to work with higher water levels in the shallow pools.
The catch wasn't quite as large as two weeks previous but we did get slightly more diversity with four species. We added a new species for the Bann Estuary with a Knot which are normally scarce here but there were up to 46 present over a few weeks this August.

Black-tailed Godwit

The final catch was 15 Redshank, 8 Dunlin, 2 Black-tailed Godwits and the single Knot. Before the waders I set a single net along a thin strip of phragmites reeds and managed to catch 10 Swallows with a number of others attracted in as we took the net down.

Barn Swallow

The controlled Redshank was originally ringed in Kent in the south-east of England on the 30th of August in 2018. Going by the wing length of the bird we presumed it to be Icelandic and it may well have been on route to the south-east of England or further south for the winter once again.

We're now approaching the end of October so it is unlikely we will do much more wader ringing in the estuary but we may get out along the Causeway Coast.

End of summer update

Yet again I have been slacking with the blog updates following a holiday in Hungary & Slovakia and I'm currently in the process of moving in to my new house. I'll hopefully get sorted in the next week or two and be back in action.
I received some great news from the BTO midweek to say that my application was successful and I have now been granted my A permit and I am also now registered as a ringing trainer!

So...... we have been semi-busy in the past 6 weeks with some more Storm Petrel ringing, general passerines, a trip to Copeland Bird Observatory, waders and we have been back down to Lough Neagh.


Lough Neagh, Take Two

Back on the 13th of August, John, Steve and I met with Godfrey and returned to the west shore of Lough Neagh where we had the very productive catch of 102 birds on the 16th of July.  We had another brilliant session with a slightly lower catch of 93 new birds but it did consist of a greater diversity and a fantastic 17 Reed Warblers taking us to 30 for the year. As an extra to the two nets we used the last time, we placed a net across the channel that separates the island from the mainland which is much closer to the wet woodland and it produced the majority of the Blackcap, Chiffchaff and Willow Warbler.
You'd like to think one or two of these 150+ acros will produce a recovery on the way south or during a later migration.

Sparrowhawk

We plan to return next year from mid to late summer and, with the right team, work the site to its full potential - 250-300 birds in a morning? A few trainees would be handy to carry the gear as the 1 mile walk through soaking reeds and swarms of flies is tough going :P



Mist-netting Waders

On August 25th John and I had a bash at mist-nesting some roosting waders with a decent forecast and a workable tide. With just the two of us on hand we stuck with just two 12m nets in a V over the main pool playing the 'Killer Redshank' tape. Ideally we could have had high tide two hours later and a bit of cloud cover but it wasn't bad.
There were plenty of birds about through the evening including 3 Greenshank, 2 Whimbrel and 100's of Curlew & Black-tailed Godwit and c30 Redshank. Early on there were 20 Teal in the pool but they were flushed by a Peregrine which I only noticed when 2 Teal landed right in front of me, which I thought was weird, when the Peregrine whizzed by and tried to nab them.

Black-tailed Godwit 

With the nets open we waited for darkness, catching one Redshank early on. The roosting birds began to move about around an hour after sundown and we ended the night with 16 birds of four species.

Dunlin

We had hoped to have a few more attempts through September, as well as some Swallow roost catches but as mentioned I've not had the time but there are still a few weeks left yet to make it happen! 


Storm Petrels

On the Storm Petrel front we made our last two attempts of the season (six in total), again with a few visitors, this time from Northumberland.  We added another 5 new Storm Petrels and one control, taking us to a year total of 44 new, 1 retrap and 3 controls, which is our lowest since we started studying the species. We have yet to submit the details of the last control as yet but hope to sort that over the next month.

Storm Petrel

We had a little more luck with Redshank adding another 7 birds.

 Next stop Tiree in a due north path

Portstewart Strand

We have had three visits to Portstewart Strand on the 20th & 27th August and the 17th September and the combined ringing totals are below. There have been a few odds and sods around the estuary and my species total as of 19th Sep is now up to 115 including a roosting Long-eared Owl, Curlew Sandpiper, Sooty Shearwater, Great Skua and finally my first Collared Dove after 4/5 years of waiting! I've also been missed plenty in the estuary in the past month with Osprey, Sabines Gull (which would both be NI ticks for me), Little Stint, Arctic Skua and Ruff sighted by others. 

The Blue and Great Tits all appeared on the 17th September with 4 of the Chaffinches showing the changing of the guard. The final Willow Warbler of the year was caught on the 27th of August, one day earlier than the final bird of 2016. The Starling was caught in an evening catch.

We are approaching peak season at Portstewart Strand and John has 3 weeks of holidays coming up so we will be hoping for plenty more ringing in the coming weeks. We have also not had a suitable team where we can use all the nets so it will be nice to have some of the lesser-spotted trainees in tow.



Copeland Bird Observatory

On the 1st of September I headed over the Copeland Bird Observatory with a team of 11 others on a special trip to ring Manx Shearwater chicks during the peak emergence. I was planning on staying through to Sunday but the terrible forecast meant that we had to be taken off the island on Saturday afternoon.
In the down time waiting for darkness I had a shot at ringing some waders and was successful in catching one Redshank. Very little wader ringing has taken place at CBO in the last few decades and wader numbers are still very low on the island at this time of year but if I get another weekend visit this autumn I'll make a bigger effort. When the sun went down we headed out across the island in three teams of 4 and caught 173 new Manx Shewarwaters and dozens of retraps. I headed for bed at 1am so I could be up for 6am to open the mist nets to catch some migrant passerines. Some of the others lasted until around 4.30am.

I didn't actually record the number of birds caught in the nets in the morning but we did get 30+ birds made up mostly of Goldcrests, Robins and Swallows plus 4 Chiffchaff, Wren, a Blackcap and some of the resident retraps. We also found a late Woodpigeon nest with two chicks which were ringed.


There have been a few more birds processed with two mornings at the river site with a catch of 30+ birds made up mostly of Warblers, particularly Chiffchaff, of which we catch very few of.  I also had an attempt of catching the Jays in my parents garden but ended up catching the same Magpie three times and the rats have now eaten my big of peanuts yet again!

Waders and Swallows - Take 2

After the success of last Wednesdays wader and Swallow roost catches we went for a repeat performance on Monday evening (http://causewaycoastrg.blogspot.co.uk/2016/09/wader-bonaza-and-roosting-hirundines.html).  The prospects were a little better with high tide peaking roughly an hour after full darkness and we were a little closer to peak Swallow time in the estuary.  We had a team of five this time around with John, Ken, Siobhan, Steve and myself and the nets opened for around 7.30pm.  The evening was a scorcher with full sunshine and temperatures hitting 25°C at 7pm and although it clouded over a little, it was still a muggy 20°C on departure after 11pm.   

Snipe

The Swallow tapes worked immediately and attracted in c25 birds within a few minutes and over the next half an hour birds continued to trickle in and swarm overhead totalling around 1000 birds.  The commotion stirred up the resident Water Rails with 4/5 calling all around the reedbeds.  With the lower tide we were able to set two separate 18m nets slightly further in amongst the reeds. 
As with the last attempt, a number of waders and Teal etc. were flushed out of the pools when setting up the nets with the majority not returning.  We opted for the same set up but with an extra 18m three shelf net in the other pool without a tape.  The drier weather of late had dried out the pools a little, but as I write, it is raining cats and dogs, so I don't think it will be an issue on our next visit. 
There were a few other bits and pieces around the estuary with a Grey Seal, Otter and a couple of pipistrelle bats.

Sunset over the estuary

Given the number of Swallows that we had attracted in and the number that had dropped into the nets early we had to switch off the tapes.  The big flock circled overhead while we processed the other birds and eventually settled into the reebed just before dark.  Half had dropped in a bit earlier but a bird of prey (which we didn't get a proper look at) had flushed them back up. 
We caught a total of 73 Swallows, 4 Sand Martins and a single Sedge Warbler.

Last couple of Swallows being processed

For the waders, we again had to wait for complete darkness before the birds appeared and hit the nets.  We had an initial good catch but only a few birds in subsequent rounds.  The catch was quite different from the previous with some larger species in Bar-tailed Godwit, Black-tailed Godwit and Curlew and only a single Dunlin.

Curlew

We are planning on heading to Portstewart Strand on Saturday morning with another attempt at Waders/Swallows at the start of next week if we can match up the weather and tides!  The stormy blast from the south this evening is probably good news for the guys on the south coast and the islands of the east and west but it might just produce a little bit for us - fingers crossed!
 
There are a few nice birds around the north coast at the minute including a couple of Little Stint and two Little Gulls at Magilligan Point pictured below.

Wader Bonaza and roosting Hirundines

On Wednesday evening (31st of August) Ken, Steve and I attempted a double roost catch, targeting hirundines and waders.  We had earmarked our Grangemore site as having great potential for both species groups, so thought there was no time like the present to test it out!

The conditions were ideal with 10-15mph westerlies blowing over the open saltmarsh while remaining cloudy and dry.  The reedbed, where we were targeting the hirundines, was much more sheltered by the deeply eroded river banks.  The timing of high tide wasn't perfect, coming at 19.45ish, roughly an hour and a half before darkness.

Curlew Sandpiper (Left) and Dunlin

We haven't quite worked out where all the estuaries waders, gulls, terns etc. go to roost.  There are 1000's of birds at low tide but the vast majority head out the mouth of the river at high tide.  The most likely location are the Skerries Islands off Portrush, which are 8-9km away and it is almost certainly where the gulls head; including the hundreds from further up river.  The nearest shores of Lough Foyle are 13km away and are a possibility for waders, although it would be the turf fields of Myroe which would be most suitable for roosting, but the 20km seems unlikely (why bother return the Bann Estuary twice a day?).  We have no idea about the Terns but the beaches of Magilligan Point (11-12km) or perhaps the Skerries would fit the bill.
What we do know is that perhaps up to 500-750 waders remain to roost in the estuary at this time of year, mainly Curlew, Black-tailed Godwits, a few Redshank and perhaps a couple of hundred Calidrids (a number seem to roost on the piers at the mouth of the river).  The oxbow lake (very shallow, partially exposed mud) holds the main concentrations (when not disturbed) and seems to appeal to a wider range of species, perhaps due to the water being less saline and the more consistent levels.  The oxbow lake is cut off from both rivers, sitting a few feet above high tide and surrounded by salt marsh and wet meadows.

Wader nets

We opted for two 18 metre wader nets in a 'V' shape over the open water of the oxbow lake, which is no deeper than 25cm.  On arrival there were 200/300 birds on the pools already with all but a few Dunlin, Teal and Snipe flushing.  We placed a tape lure in the middle playing the infamous Redshank tape from the Wash. 

Trying for roosting hirundines was a first for the site but the habitat (reedbeds) is much better than our usual site plus it is in close proximity to our Grangemore Sand Martin colony.  I had created a net ride through the reedbed earlier in the year for Sedge Warblers, which was around 50 metres long but the high tide meant we could only use the last 12m.  We added another 18m net running at the edge of the reeds to create another 'V' shape'.  A Swallow and Sand Martin tape lure were placed in the centre.

Net locations

A few Dunlin and Black-tailed Godwit showed a little interest early on when it was still bright but the nets were a bit obvious.  Four/five Dunlin did fly into the nets but only one stuck with the rest bouncing out and a few others going under.  We altered the nets a little making the pockets a bit deeper and slightly lower, but still high enough to keep a big bird out of the water. 
  
The hirundines built around sunset and we managed a catch of 15 Swallow, 6 Sand Martin and 2 Sedge Warbler.  There didn't appear to be many more birds about, so a decent catch.  While keeping an eye on the other nets, we ringed and released the birds straight from the nets (still light) and closed up. 

Ruff

Just after dark, perhaps 300 waders appeared and descended on the pools giving us an initial big hit.  We turned the tape off straight away as we were not equipped for too large a catch.  The result was really pleasing with 20 birds in the nets of five species.  The majority of birds were Dunlin (14) plus 2 Redshank and 1 Black-headed Gull but the real big surprise was 2 Ruff and a Curlew Sandpiper.
These two species were new ones to us and very unexpected.  The Curlew Sandpiper is the first to ringed in Northern Ireland since at least 1977, possibly ever.  In the same period there were only 4 Ruff ringed in Northern Ireland with the last one coming in 1983.
