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.

River Tripple Crown

With the persistent weekend winds keeping the nets down at the Bann Estuary I decided to try a little river ringing. In recent years we have kept much of the river ringing for training purposes plus the continuation of Ken's study of the Irish Dipper.

I headed over to the River Rhee on Saturday the 23rd of March which is our regular hotspot for Dipper, Grey Wagtail and Kingfisher where we have caught a number of the years.

Dipper

I had an instant capture of a retrap Dipper which I had originally ringed on the 26th of March 2016 before another bird bounced out of the net twice- I  keep the bottom shelf quite tight to ensure the bag of the net doesn't droop into the water with the weight of a bird but at the same not too high to allow the birds to fly under easily.

Kingfishers (female top - male bottom)

Next up was a pair of Kingfishers in the net, again one slipped out but the male came back down and was captured on the second pass.

Grey Wagtail

A always find Grey Wagtails the most difficult to capture and today was no different as they always notice the net - flying over, around, walking under it and evading capture. I got lucky with one towards the end of the session but it's partner wouldn't join it.

Early December Ringing

This morning Steve, Thom and I met up with a group from Copeland Bird Observatory at a winter ringing site near Antrim.  The site has been used in previous winters for training sessions and this time around there were five trainers and four trainees.  It was a frosty morning with the mercury hitting -2 °C but there were plenty of birds about.  The site has a wealth of fruit trees and berry bushes, which attracts Thrushes in decent numbers with c50 Redwing, c40 Blackbird, c10 Song Thrush, c10 Fieldfare and a couple of Mistle Thrush around this morning.  The feeders brought in plenty of tits and finches but the a real draw was an area of winter cereal cover which held c35 Linnet, c30 Chaffinch, c25 House Sparrow, c15 Lesser Redpoll plus a few other bits and pieces - a proper net combination here should work well in the next sessions.

It was a productive morning with 84 birds processed of 16 different species.  One of the first birds to hit the nets was a nice male Sparrowhawk flying low around the feeding station.  A Grey Wagtail amongst the Apple trees was unexpected but gladly welcomed by one of the trainees.  All four trainees managed to get new species, including two who got multiple new birds.  We only managed to trap two species of Thrush but 11 new Blackbirds is very good, a few of which were certainly of a continental origin.  We wrapped up at 12.30 just before the rain started.

On Tuesday morning Ken hosted Steve for a bit of training in his back garden and were joined by John later in the morning.  The morning was an ideal weather window with dry, calm conditions, plus it wasn't freezing for the ringers! 

They caught a large number of birds and had to close a couple of nets in order to cope - hence Johns arrival.  A total of 102 birds were processed, with perhaps 35% of these having been caught before.  There are a few nice birds in the garden at the moment including two Brambling and two wintering Blackcaps.  Unfortunately the former weren't caught but they might stick around with the c50 Chaffinch.  The Sparrowhawk ringed last time out has continued to visit daily and was retrapped.

Portstewart Strand 23/05/2015

I was optimistic for the session ahead with near perfect conditions.  The winds were 2-3 mph south-westerlies, full cloud cover and a mild start of 10°C at 05.15.  The conditions remained decent through the morning, although the clouds broke and the wind notched up 4/5 mph.  I departed the site before 11am with the temperature up to the middle teens.  
 

The scrub has now leafed up nicely and the net rides are looking much better, although some of Sea Buckthorn may need a few months to regenerate some new growth after cutting.  The local breeding birds are now remaining very quiet and there wasn't much of interest.  The best bird of the day was a female Cuckoo that zipped by mid morning, pursued by an army of Meadow Pipits.  The local Otter was fishing close to the shore for much of the morning and later joined by a Grey Seal.  The first Small Heath butterfly of the year, was on the wing, along with multiple Green-veined White and Speckled Wood.

Meadow Pipit

The catching was again slow and you would be excused for thinking that it was late autumn/winter, with a complete lack of warblers.  My optimism soon dissolved but the prospect of something nice always keeps you going.  The best catch was the first Skylark of the year, caught in the 3 shelved gorse net.  Another 2 new Blackbirds takes the total to 38 in 7 months.  The Meadow Pipits in the close vicinity of the gorse scrub seemed very active, with 5 birds ending up in nets.

I had noted a pair of Grey Wagtails feeding along the river by the house so I thought I'd take a look for the nest on the near by stream.  They tend to nest on the same large rock face every year, although I was unable to locate the nest this time, but, going by the adults, I was close.  I had erected a net just downstream and managed to catch the female.  The Dipper nest is now empty and presumably they have fledged but I didn't see any of the family group about.

I also visited the 30 (now 29, one missing) nest boxes in Castleroe Wood, late Saturday afternoon. The occupancy was very disappointing with only 7 boxes (plus one failed nest of 4 GT chicks) being used, compared to 21/22 last year.  Those that were occupied were dominated by Great Tits, with 6 nests and Blue Tits taking up residence in the other.  As well as low numbers, the birds are also late, with only two broods of ringable size and three nests still with eggs.  I ringed the two clutches of Great Tits of suitable size, one of 7 and the other of 3.
