Return to Lough Neagh - 2019

After the great success of our Lough Neagh ringing site in recent years we were very keen to get back on the shore and open the nets. Making best use of the bank holiday weekend and a good weather, we decided to go for the first visit on Saturday 13th of July. John and I were short on helpers and lost three people the day before but we were joined by two fairly new trainees in Abbie and Rich K.

Sedge Warbler

In the last few years, the first rush of birds is usually underway as we are setting the nets, so we decided that an earlier start was needed. We set off form Coleraine at 04.30am, arriving at the parking area around 05.30am, on site 30 mins later after the walk in with the gear and then a further 30 minutes to get the 7 nets (run of 4 & 2) opened.

The catch was another busy one with 119 new birds including another 76 new Sedge Warblers, 10 more Reed Warblers and our first two Grasshopper Warblers for the site.

Visit two took place a few weeks later on the 27th of July. We had planned for this morning with a team of 11 assembled but the weather changed & we had to bring it a day forward, leaving it with just myself, Steve, Abbie and also Joe, who had travelled all the way from Donegal.
As usual with the site, the onslaught of birds began at once and two nets were closed early and further two furled temporarily. The birds die off completely by 10 am.
The result was a big haul of 220 new birds which included 20 Reed Warblers, surely an Irish daily record. The 167 Sedge Warblers ought to be up there for a record catch also.

We didn't catch any retraps and given that we have previously ringed 782 birds in 6 visits here, the birds are clearly moving through the site



Yet again we managed just the three visits despite all our hopes and talk! Visit three took place on the 25th of August where we had a good team assembled with John, Ken, Jim Mc, Abbie, Rich K, James O and Nathan giving us a team of eight. With extra hands we increased the nets and covered four net sites with nine nets. It was a bright hot day which seemed to effect the birds. It was the first time at Blackers Rock that we haven't had a big movement of birds early doors and instead there was a steady trickle right through, until we took down the nets. There were much fewer birds seen and heard but there were still lots skulking amongst the reeds. We were only really catching birds in the shaded parts of the nets, often just a few feet on some.
It was another healthy catch of 154 new birds, a BTO control Sedge Warbler and a single retrap Blackcap, although we would have liked 300+!

Total                              154                  



I've totted up the totals and put them in the table below. It was somewhat similar to last year in that the middle visit (27th July) produced the biggest numbers with more Sedge Warblers and the final visit (25th August) produced the greatest species diversity. 491 new birds compared to 2018's 464.


Sedge Warbler - 323 (1 BTO control, 1 retrap)
Reed Warbler - 55
Willow Warbler - 34
Blackcap - 24 (1 retrap)
Reed Bunting - 22 (1 retrap)
Blue Tit - 7
Robin - 6
Chiffchaff - 5
Grasshopper Warbler - 4
Wren - 4
Swallow - 3
Dunnock -3
Goldcrest -1
Total - 491 new birds



Although we had a great team of 8 for visit three, the first two visits (visit 1 - 13th July) were limited by only having four people present, particularly on visit 2 with two trainees, a C and A dealing with 220 birds which could have been much more. Weather was again difficult and there was a full month between the 2nd and 3rd visits and it twice put off plans of ringing on two consecutive days.
Reed Warbler numbers again peaked at the end of August, maybe they are even better in early September? The catches on the 27th July and 25th August were each record daily catches for Northern Ireland, probably Ireland also. The guys at Traad Point at the north of the Lough have caught 58 Reed Warblers throughout the c10 CES visits so a bumper year for Reed Warbler in the north.
Willow Warbler numbers were almost double this year while Reed Bunting numbers were quite a bit lower after the exceptional catch of 53 new birds on the 11th of August last year. Sedge numbers seemed like they might be a little lower this year after visit one but we caught a record catch of 167 on the 2nd visit, 70 more than our next best days catch.
Just the one control in the form of a Sedge Warbler bearing a BTO ring - it hadn't travelled far, having been ringed at Traad Point CES 10 miles up the shore but pleasing all the same as its our first exchange of birds.


No doubt we will get anther 2-3+ recoveries of birds heading south or on the way back north next spring. We only caught two inter-year retraps and one same year retrap, so we are still missing much of the local breeding population.
Bigger and better next year! (if the Irish weekend weather allows it).

Spring in to Summer in the Bann Estuary

Early summer is normally a quiet period for us at our regular ringing sites with the majority of the birds still on eggs or feeding their chicks, resulting in small catches.
The main feature of June each year is usually the first visit to the Sand Martin colonies in mid-June and our visits to the Sandwich Tern colony in Donegal. July marks the return to the nocturnal ringing of Storm Petrels and the first trip to Lough Neagh for acro warblers.

After some promising weather at the start of June we got stuck in a rut of rain and showers with the Jet Stream stuck to the west and south of the UK and it stayed there for almost two weeks. This meant that dry days were few and far between, particularly at the weekend. Through spring and summer it was just myself over the six morning visits between Kilcranny and Portstewart Strand.

John has been putting in a greater ringing effort at the River Site at Ulster University Coleraine just up river but I don't have his ringing records to hand.

Grasshopper Warbler

Long-tailed Tit is a common bird in most areas but not one we get around the outer Bann Estuary sites. For my year patch birding, I'm usually reliant on finding some in Kilcranny Wood and one was added to the ringing list for the estuary. A couple more Grasshopper Warblers were great as we usually only catch a couple each year. Starlings are very common locally, as everywhere, but we don't normally catch (or attempt to) many. In fact in the last four years we have only caught one Starling per year at Portstewart Strand, in the same net set, in June and all juveniles - we've now bucked this trend with catches of three and seven. We seem to catch one single Wheatear each spring and 2019 was no different.

Starling

I managed two weekend stays at Copeland Bird Observatory at the end of April and mid-May. The weather was pretty unkind for both, with Storm Hannah hitting on the first and prolonged northerly winds for the second, so migration was almost non-existent. We did get a few Greenland Wheatears, Swallows etc. but nothing out of the ordinary. On the second visit, with a team of 9 visiting ringers, we put more of a focus on breeding birds ringing female Eider ducks, Herring Gulls, Lesser Black-backed Gulls and also a Mallard. A Stock Dove was a nice catch and CBO is probably the only place in NI any have been ringed this century.

More Warblers

Last July I tested out a new site that I had been eyeing up for quite a while. The reedbed at Kilcranny is the largest in the estuary and it backs onto a fantastic Ash wood with marginal wet grassland habitats and Willow scrub. Access had previously been the main hold up with a walk of a few kilometres down farm lanes, barbed wire fences to hurdle, an overgrown understory of brambles to traverse and then crossing of the fenced railway line plus the risk of high tides. With a bit of investigatory work, I found a much simpler access route on the nearside of the railway with some fantastic habitat. 

On the tester on the 29th of July utilising some temporary net rides for three nets in existing gaps I caught 12 Sedge Warblers and a single Willow Warbler. The site contains six species of breeding warbler and on my visits in recent weeks I have heard five back on site including 3 reeling Grasshopper Warbler - still waiting for the Whitethroats in the estuary but they aren't particularly common here. 

Grasshopper Warbler
I visited the site on Bank holiday Monday (6th May) & put up a 3 nets once again although I avoided the main reedbed as the water was a little high and rain was forecast to appear mid-morning. The site has loads of breeding birds and warblers although distributed over a wide area, many away from the nets. I managed a nice diverse catch including the five warbler species present with a Grasshopper Warbler the best of the bunch.

Sedge Warbler
 
I'm looking forward to trying the site properly in late summer/early autumn once the breeding birds begin to disperse and move around the site. 
 

John has made a few visits to his ringing site along the river at the Ulster University Coleraine Campus. The range of sites we use in the wider Bann Estuary are actually quite well connected now that we have opened up Kilcranny to plug the formerly large gap up to the university. We have had birds move between Portstewart and the Uni River site and Portstewart to Castlerock but it will be interesting to record any other further movements between all the sites.


 
The river site has chipped in with a number of warblers and had a particularly good movement of Blackcaps passing through the scrubby woodland with 10 trapped on the 23rd of April.
