Copeland Bird Observatory 17-18th of September & PSS

After our 13 hour delay getting to Copeland Bird Observatory due to the tide, we set sail from Bangor at 7am, all a little weary eyed.  As well as Dean, Steve and myself, we were joined by Laurence from the Belfast and Down Ringing Group for the weekend.  The trip out was a new route for us leaving from Bangor and it was a real treat with perhaps 500+ Razorbills all around the mouth of Belfast Lough with a scattering of Black Guillemots, Guillemots and Eiders along the way. 
We arrived on the island around 8am and immediately set about opening the traps and getting some mist nets up.  We used the usual lot of the favoured net rides and opened the 4 helgoland traps, crow trap and a few potters baited with sardines.

Water Rail

The weather was decent with moderate westerlies for Saturday morning switching to southerlies in the afternoon for the rest of the weekend.  Saturday was a hot sunny day, where as Sunday was a little greyer with light drizzle as we were getting ready to depart mid-afternoon.

The range of migrants on show was lower than expected but a couple of species passed in large numbers.  Swallows and Meadow Pipits were the main feature with probably 800+ of the former and 500+ Mipits passing over the two days.  As usual in September, Robins begin to arrive back on the island after heading elsewhere for the breeding season.  A number of adult birds were reencountered that hadn't been seen since the spring plus a number of new juveniles.  Finches arrived on Sunday with 80+ Goldfinch, 40+ Linnets, a couple of Chaffinch and a single Lesser Redpoll.  Lesser Redpoll will soon become the dominate passage species as the autumn progresses with over 800 ringed last year!  There was a light scattering of Chiffchaffs, Goldcrests, House Martins and singles of Skylark, Song Thrush, Sparrowhawk, Willow Warbler and a migrant Blackcap. 

Swallows

The ringing was pretty decent in terms of numbers which were bolstered by the three main movers with 22 Swallows, 14 Meadow Pipits and 13 Robin.  The first couple of rounds on Sunday morning produced the majority of the new Chiffchaffs (5) and Golcrests (3).  The Chaffinch caught is more than likely a controlled bird although it could have been ringed on the island 6+ years ago.

On Saturday night, as we were heading out shearwatering, we got a nice a surprise when we captured a Water Rail in one of the baited potter traps.  The bird was already bearing a ring and was originally trapped on the island back in 2012.  Despite the very bright full moon we managed to ring 29 Manx Shearwaters which were all pulli or recently fledged birds.  We also set the moth trap to run through the night but the catch of 5 moths of three species was pretty low and they were outnumbered by Sexton Beetles who do a great job clearing up the bird and rabbit carcasses across the island.

All in all it was a very enjoyable weekend and we are looking forward to the next visit in mid October is the weather allows it. 



On Tuesday morning John and I squeezed in a quick visit to Portstewart Strand to make the best of the conditions before a delayed start to work.  There had been a report of a possible male Common Yellowthroat a couple of hundred metres further along the shoreline a few days before and although the bird had been searched for by others unsuccessfully, a number of Blackcaps and Chiffchaffs had been sighted. 

Sunrise

We were on site bright an early and had the nets up by 7am.  The wind was a little brisker than forecast but that is usually the case with southerlies where they blow straight off the river.  It was evident that there had been an arrival of Robins with a number ticking throughout the scrub before first light.  Other new birds included Blackbirds and a few extra Bullfinches than of late.  Once the sun had risen and things heated up a few Chiffchaff began to call amongst a roving flock of Goldcrests and a few Blackcaps appeared. 

Chaffinch

The main entertainment for the morning was the local juvenile Peregrine who has been terrorising just about every bird in the estuary.  Today it was testing out 4 Ravens, 11 Grey Herons in the roost and every duck and wader in sight.  It seems to have the most luck lifting the Black-tailed Godwits of which there were 140+ this morning.  It eventually made a kill before the tables were turned and the Hooded Crows tried to muscle in.  A second juvenile Peregrine appeared before we left around 10. 

The ringing was slow in the shortened sunny, breezy session but it is nice to see the arrival of some migrant Blackcaps and Goldcrests and hopefully a sign of the start of proper autumn migration.

The weather forecast is looking grim but there is a chance of short session on Sunday morning.  Dean and David S are heading off to the south coast of Ireland tomorrow to the fabled Cape Clear Bird Observatory (I'm just a bit jealous) for a weekend ringing course.  Cape Clear is easily the best birding spot in Ireland for autumn passerines, particularly from North America and if they hit the winds and weather right, they could be in for an amazing weekend.  Dean and David will be back next week with an update and pictures of their trip. 

 

Copeland Bird Observatory 2nd - 4th October

After our routine pre-CBO 'chippy', John, Ken, Steve and I were ready to jump into the RHIB and set sail for Lighthouse Island.  We met up with Island regulars David, Philip and Ian at the harbour in Donaghadee, who were accompanied by Olli, on his first trip.  As forecast, the winds were very light and the sea was flat calm for a change.
On arrival on the island, we set about readying the nets and traps.  With 6 ringers on hand we set a few extra nets than the norm, covering most of the north and east of the island.  In total we set 10 mist nets, with the 4 in situ Heligoland traps, the crow trap, plus 7 spring & potter traps.     

Lesser Redpoll

When setting up it was evident there were a few birds knocking about and we caught a couple of Blackcap, Goldcrest and Song Thrush before sunset around 7pm.  After dark, a few us headed out in search of a few Manx Shearwaters but with little hope.  It is very late in the season and the majority of the chicks should have fledged and be on route to the southern hemisphere.  Luckily we managed to find 12 new chicks within half an hour and the following night added 5 more. 
  The CBO team along with Oxford University were successful in retrieving 3 geolocators from adult birds over the summer.  These had been attached 3/4 years ago when the birds were chicks in their burrows.  It is not known exactly what young shearwaters do from their first migration south until they return to the breeding colonies 3/4 later.  Hopefully the data can be extracted and it will shed some light/confirm peoples thoughts in what they do!  For updates on the project, follow Copeland Bird Observatory on Facebook - https://www.facebook.com/copelandbirdobservatory?fref=ts

Linnet

The next day, we were up before dawn (two of us anyway!) to open the nets and get ready for the mornings ringing.  Again the conditions were ideal and the birds started trickling out of the bushes and into the mist nets.  The birds consisted of Blackbird, Blackcap, Dunnock, Goldcrest, Robin, Song Thrush and Wren.  It wasn't long before the finches got moving with flocks of Goldfinch, Lesser Redpoll and Linnet moving around/over the island plus c30 Skylark.  With the help of tape lures we picked up 73 Lesser Redpoll and 11 Linnet, before closing the nets early afternoon.  A Hooded Crow found it's way into the crow trap for a second time, following its initial foray in April.  The sea remained quite for the most but totals of 1000+ Razorbill, 500+ Gannet, c40 Eiders, c50 Harbour Porpoise, a few Red-throated Diver and other bits and pieces kept Ian content.  The Grey Seal breeding season is in full swing with at least 40 seal pups spotted at the Observatory and on the near side of Mew Island, with probably many more around the rest of Mew and Big Copeland.  The bulls (males) were also getting very frisky, as the females come in to season.

  Adult Grey Seals

On Sunday morning the conditions were perfect, with next to no wind and a good covering of cloud.  The initial net rounds showed there had been an arrival of Chiffchaff, with 14 ringed in the first few hours.  The catch was similar to Saturday but with an added Wheatear from the 'Heli Trap' at first light, a Woodpigeon from the 'Thicket' net and a Meadow Pipit in a spring trap.  Again the finches got moving with Linnets (including a flock of c50), hundreds of Lesser Redpoll, plenty of Goldfinches and a single Chaffinch.  The Lesser Redpolls surpassed the previous days totals and this corresponded in the ringing totals, with 103 new birds.  The sea was again pretty quite but 3 Great Skua, c100 Curlew and a few extra Black Guillemot was something.  No Hirundines were noted all weekend.

Overall it was a very enjoyable weekend with lots of birds ringed and some good weather.  Unfortunately we couldn't produce one of the Yellow-browed Warblers, that have pouring down the coasts of the UK and Ireland, that we were hoping for.

End of August Update

The last few weeks of August have been pretty quiet in terms of ringing, with some poor catches.  Mondays session at Portstewart Strand marked the change of the seasons and the arrival of autumn and a decent catch.

The first session was the 7th attempt at catching Storm Petrels on Wednesday the 19th.  It was John, Steve, Ken and myself present in ideal conditions.  The first bird was caught 7 minutes in, after opening the net at 22.25.  It was slow going, so Ken and myself left around midnight, while the other 2 persevered until 01.30.  They managed to add a couple more Storm Petrels, taking the nights total to 12.  Their perseverance was rewarded with a new species for the group, in the form of a juvenile Turnstone. 

Turnstone

On Saturday the 29th John, Ken, Alison and I, attempted a combined night of a Swallow Roost catch and the final Storm Petrel visit.  It was a bad night, with the roosting Swallows yet to have gathered, resulting in just 1 Swallow caught.  At least it was new species for Alison!  We will probably leave it a few weeks and hope that some Swallows materialise before attempting again. 
The Storm Petrel visit was late in the season and the catch of zero birds suggests why.  The massive bright moon probably didn't help the nights ringing.  This marks the end of the season with a total of 104 new birds, 2 retraps and 4 controls.  This is pretty poor result, with a much lower catch than the previous three years, with similar effort. 


I have managed two sessions at Portstewart Strand in the last two weeks.  The first was on Saturday the 22nd and, like the week before, I needn't have bothered.  It was a very quiet session with little to nothing about and an absence of the usual common species.  The total was just 9 new birds and 2 retraps.  Dunnock 3, Bullfinch 2, Blackcap 2, Wren 2 and 2 retrap Bullfinches. 

Bullfinch

 

Blackcap

On Monday morning the forecast looked more promising with a change in the winds, now coming from the north.  Given the location of the site, we probably need some form of northerlies in autumn to bring us anything.  Steve and I met on site at 05.30 and set up east ride and gorse nets + the 12m in the Alders and the first 24 metres of west ride.  The conditions were decent, with light winds and it was overcast. 

Stonechats

The change in the seasons seems evident in the exchange of birds.  The only Warblers present in the last couple of weeks have been the Blackcaps, with the rest headed south.  On Monday there were signs that the autumn birds are moving with the first Goldcrests (c8) since spring, c25 Robins and an arrival of c75 Meadow Pipits.  Other birds of note were a pair of Kingfishers chasing each other back and forth across the estuary, making them the first of the year.  Other birds of note on the estuary recently include up to 13 Ruff, 1 Knot, 3 Greenshank, 5 Common Sandpiper and a Ring-billed Gull.   

Meadow Pipit

Overall it was a pretty good session with good numbers and a decent selection of birds but disappointingly, only a single warbler.  The Meadow Pipits were playing ball today and despite a few slipping the nets, we ringed 28 new birds.  The local Stonechat family were knocking about, with what I presume to be their second brood and we caught 2 juveniles.  The Bullfinches keep coming and the catch today takes their total to around 35 new birds since last September.

Steve and I are heading over to Copeland Bird Observatory for the weekend, so fingers crossed for some nice birds.  The forecast is looking quite windy from the north but we can hopefully make it work.  The wind seems to have been a persistent problem for our visits this year.
