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).

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.

The Warblers are back

With the sounds of our favourite species group - the warblers, back on territory, we have visited some our regular spots to catch up with some old friends and meet the new cohort.
By the end of April we've had our regular six breeding species back which include Blackcap, Chiffchaff, Sedge Warbler, Whitethroat, Willow Warbler and most pleasingly, Grasshopper Warbler. For regular readers you will know that there was a complete absence of Grasshoppers over most of Northern Ireland last year and I hadn't seen or heard a single bird. Things seem to be back to normal this year with at least five territories back in the Bann Estuary and probably a few more to come.

Some good weather over the five day long Easter weekend gave the perfect opportunity to get out and open the nets. I made three visits to Portstewart Strand in this period with a great morning on Good Friday encouraging another the following day and again out on Easter Tuesday.

Willow Warbler

The first visit seemed to be very well timed with a catch of 14 new Willow Warblers which is a daily record for the site, most were females and caught moving through the gorse bushes. The same nets also produced 13 new Linnets. A female Greenland type Wheatear was the last bird in the nets and keeps up our track record of catching one Wheatear each spring at the site.

Sedge Warbler - dirty nails are regular when ringing here

The Sedge Warbler on the 19th of April was my earliest ever beating the previous record held by a bird at Copeland Bird Observatory on the 24th of April in 2016. My earliest Sedge Warbler around the Bann Estuary is the 29th of April in two years & the 30th of April in two others, so certainly an early bird.
One of the Bullfinches retrapped was also an old lady having originally been ringed as a female on the 20th of November 2014 born in that year.

The middle gorse net at first light

Having had such a good catch (in limited nets) I opted to go again the following day in what appeared to be an even better forecast and added an extra net.
The result was disappointing with very little moving and much fewer birds seen out on the estuary.

Linnet

The third visit was on the 23rd of April and although the conditions weren't overly promising but the nets were sheltered from the northerly wind. It continues to be a strong start of the season for Willow Warblers but many will have to find new territories elsewhere with a lack of habitat to serve them all. We tend to catch more Linnets in the autumn with the use of tape lures but we seem to be doing particularly well this spring. There are certainly 2/3 breeding pairs right beside our nets but there are still small flocks passing through the gorse (tape lures have not been used).
