Portstewart Strand Dunes Autumn 2019

Autumn at Portstewart has been ticking a long with reasonable catches but no stand out birds or large catches as yet. Effort has been down quite a bit as I've been running solo at the dunes up until the middle of October and I have otherwise been distracted getting married in mid-September then heading off for a few weeks to South Africa & Dubai.

Fieldfare


In total since August there have been 11 visits, 3 in August, 5 in September and 3 in October with 254 new birds caught. The most productive visit was on the 18th of September with 68 birds trapped, made up of a big catch of Linnets. I've been making more of an effort to catch Linnets this autumn in the hopes of getting some retraps and build a better of picture of where the birds come from. At the moment, the only retraps I generally get are during the breeding season when a couple of pairs seem to nest very close to a couple of the gorse nets. Otherwise, the flocks of birds passing through seem to be new.

Linnet

We added another new species for the Bann Estuary with the capture of a Grey Wagtail using a tape lure early morning, a further two were attracted in on the same morning but not caught. The Fieldfare caught on the last visit on the 21st of October was a first for the dunes at Portstewart Strand. That makes it 59 different species trapped in the estuary since autumn 2014, with 43 species trapped at Portstewart Strand.

Willow Warbler

At the moment it's looking to be a very poor year for Blackcaps and Reed Buntings, effort on catching Meadow Pipits has been down and Blackbird, Song Thrush and Chaffinch numbers are lower but generally October and early November are the best period for those. Willow Warbler has done quite well since the drastic habitat loss but still less than half the number caught in 2015.


The remnant scrub is very patchy and undoubtedly we have lost a large population of breeding birds. My hope is that the migrants passing through will still remain consistent but with much fewer ideal net rides and with those remaining more susceptible to the wind, it makes it more challenging.


What remains of my favourite former net ride, which used to measure 90 metres, now only fits a 9 metre net - it was great for Blackcaps and chipped in with Garden Warbler & Lesser Whitethroat.

One thing that has remained consistent is the continual flow of litter down the river. My new pet hate are shotgun cartridges and wads which are never ending both here and at Lough Foyle and I've gathered 200+ this year. Every little bit I can do as I walk between nets does build up to be quite substantial.

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.

Total                              33              7


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.


                                     New        Retrap
Blackbird                                         1

Wren                                                1

Total                              9              6    

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).

Bann Estuary 2018 Bird and Ringing Report

The Bird and Ringing Report for 2019 in the Bann Estuary is now available - if you'd rather view it as a PDF, click the link below - probably easier to read as a PDF with more clarity.

2018 Season at Portstewart Strand

As you can see, my slacking in regards to posts has really gone to a new level! I would put this down mostly to the fact that we haven't been as active and for 95% of the time it has just myself and John Clarke. I have also become slightly addicted to Twitter and post most of my stuff on there - you can find me at @causewaybirds - https://twitter.com/CausewayBirds

I'll try and play catch up  on our activities and recoveries through the season so far but I can't promise it won't be another few months before the next post 😛

So another season complete in the dunes of Portstewart Strand along the Bann Estuary on the north coast and the declining picture continues.

It was a disappointing spring with only 74 new birds from 8 visits and just two visits in the summer. As usual, we were more active in the autumn and finished with 401 new birds of 27 species in total. We trapped two new species for the site with a fantastic Cuckoo and Twite.

Cuckoo

It was also very quiet on the trainee and visiting ringer front with just one T ringer on one of the 21 visits and no C permit holders. It was myself and John Clarke for 13 visits, Ken present two and eight were solo.

Twite

The focus of our activities have been centred on the Sea Buckthorn scrub, but as a none-native species and because of it's negative impact upon the SAC, it is being removed bit by bit each winter (as are the net rides with 190m+ lost already and a continual process of creating new ones), with 5 acres lost last winter. A further 9 acres is to be removed this winter leaving us with just c2 acres and a few other small areas to work with & bird numbers will continue to slide.

Perhaps not the easiest to read, but see below for the totals from the site since we began ringing at Portstewart Strand in the autumn of 2014. The right-hand box indicates the effort put in each year and as you can see it was our worst yet for a full season

There were no recoveries of any great distance with just a few local movements to/from the Ulster University Campus & Castlerock.

The weather in recent weeks has been very poor so we haven't opened any nets but hoping to shift our attentions over to Castlerock for the remainder of the year.

The next post will cover our return to the Lough Neagh shore and promises lots of acro warblers including three controls/recoveries including two to France and our first Reed Warbler control!

Portstewart Strand 30/09/2017

Well after all the debate over the weather and getting the greenlight I arrived at Donaghadee Harbour on Friday evening only to find out the boat to Copeland Bird Observatory was out of action and it would be at least Saturday morning before it would be fixed. It was a little too far for me to travel back to the north coast and return again the next morning so I gave it a miss but five of the group of eight did make it out. It is a real shame as the conditions would have been great on Saturday morning for ringing, with Sunday much windier and wet. We have had great problems this September getting to the Observatory with the preceding two weekends also not possible and this is peak time for many of our common migrants and also our peak time for rarities.

Stonechat

Saturday (30th) morning wasn't completely lost to me as I headed down to Portstewart Strand with John in what felt like a proper autumnal day and the first day where the mist net poles get too cold to touch! There was a little breeze first thing but this was to ease gradually. It did ease at times and completely disappeared only to return stronger within 10 minutes - strange!


The Long-eared Owls are still hanging about amongst the scrub and we are now up to three birds. One narrowly missed the 6m net at west ride as it was coming in to roost.
The number of new birds trapped was down on recent visits but we are retrapping more of the birds ringed in the past few weeks.

Totals                    24                 11    


I've had a sit down this week and updated all the ringing data and bird logs and had a look at our return so far. We were really slacking early season with only 92 new birds ringed between April and the 12th of July but this was generally down to effort. We are roughly 180 new birds short on our total for the site in 2016 and around 320 short on 2015. We have also handled seven less species this year but we still have around two months to improve the situation.
On the positive side, it is already our best year ever for Blackcap and Goldcrest and I would imagine we will catch a few more before the season is out.


We are planning a visit on Friday and possibly Sunday morning, and after a few days of strong westerlies we don't really know what to expect. We are shielded by Donegal so it is unlikely that any American passerines will make it our way but at least one has before! 

Great Crested Grebe

The PatchWork Challenge total is now up to 118 species with the addition of a Great Northern Diver. The first Whooper Swans, Greylag Geese and Great Crested Grebe of autumn have been sighted in the past week with the Brent Geese arriving the week before.
