Latest sightings – Copeland Bird Observatory

3rd-5th July, 2015: Scouts Return to Complete Un-Finished Business!

September 20, 2015 admin

On Friday, 3^rd July a group of 10 Explorer Scouts, with leaders John Lyons, Scott Guiler and DO Chris Acheson, arrived on the island with the express purpose of continuing work on the Gully Trap and completion of a number of other jobs. Five of the boys had been on the island for the same weekend last year and were involved in stripping the old wire off the trap, so it was fitting that they were again contributing significantly to the completion of the job. The other 5 were enjoying their first visit to the Observatory.

After settling in, etc., the group went shearwatering. Twelve new birds were caught and 12 re-trapped – the highlight was a chick from 1985 which had not been recorded since ringing (just short of 30 years).

On Saturday, the boys worked hard and completed several important jobs on the permanent traps in preparation for the Autumn season. The Gully Trap door was repaired and re-hung with new hinges and several new panels of galvanized wire were fixed in position across the trap to extend the roof significantly towards the entrance. The door of the Wall Trap was also re-hung, as it had broken off some time ago, making the trap difficult to use. A newly constructed door was fitted to the Crow Trap, completing its refurbishment and ensuring that it is now also easy to operate.

As this was essentially a working weekend, no mist nets were set, though a few birds were caught during occasional visits to the traps – most notably 5 Jackdaws together in the Crow Trap early on Saturday evening. After nightfall it was clear that many fewer Manx Shearwaters were visiting than on the previous night, so a round of the southern half of the island produced only 2 new birds and 6 re-traps, the oldest from 1988.

On Sunday morning, more roof panels were fitted to the Gully Trap and several heavy rolls of wire mesh were brought up from the Pub to the Old Buildings for storage, thus tidying up the site quite substantially. During a break in the work schedule, the opportunity was taken to visit the Black Guillemot nest sites – 7 chicks were ringed and 2 adults re-trapped (one from 2003 and the other from 2005). Two Great Black-backed Gull chicks were ringed below the Pub.

All in all an enjoyable, successful and productive weekend – many thanks to John, Scott and the boys for all their hard work and continued support of our activities on the island.

Ringing totals for 3^rd-5^th July, 2015:

Manx Shearwater 14 (and 18 re-traps)
Blackcap 1
Great Black-backed Gull 2
Blackbird 2
Black Guillemot 7 (and 2 re-traps)
Wren 5
Jackdaw 5

Weekend Visit of May 15th – 17th

May 27, 2015 admin

RICHARD DONAGHY REPORTS ON THE SIXTH WEEKEND VISIT OF THE CBO 2015 SEASON.

Breeding in full swing –first chicks of the year seen
12 species ringed – 5 new species for the year including Swallow and Whitethroat
Important work continues: habitat management resumes across the island

A team of five volunteers including Ian McKee, who planned to stay for a week to progress with the first serious attack on the grass-cutting, departed Donaghadee on Friday 15^th May for the sixth weekend visit of the CBO 2015 season. [Ian was joined for the remainder of the week by another volunteer on the boat switchover on Sunday].

The weekend weather remained dry throughout but with constant winds blowing at around 20 mph coming from the west/south west. Sunday morning brought this nicest weather with a drop in the winds and a near cloudless sky.

Beautiful morning over Mew

The breeding season is in full swing on the island with large numbers of Eider, Black Guillemot, Black-headed Gull, Common Gull, Herring Gull and Lesser-black Backed Gull sitting on eggs. The team also spotted nesting Oystercatcher and saw the first two Eider chicks of the year.

The Fulmars are sitting on the ledges on the East cliffs and a pair of Rock Pipits are bobbing around the foreshore. The pair of Starlings which nest in the workshop were working tirelessly to feed to their noisy brood, flying back and forth across the island continuously in the hunt for insects. The local Swallows were checking out the usual nest sites around the Observatory buildings and the cave. Two curious Swallows flew into the ringing laboratory on Friday evening to look for an ideal nest site and were caught and ringed.

Many of the other resident breeders remained inconspicuous, so may be sitting on eggs e.g. female Reed Buntings, Shelduck and Stock Doves. The Arctic Tern numbers are building; reaching c180 birds on Saturday 16^th May but we expect plenty more to arrive. Four Puffins were again present with two sitting among the decoys. A highlight for the species list was a pair of Red-breasted Mergansers, spotted on the sound between Lighthouse Island and Mew.

Spotted Flycatcher

In terms of passerine migrants (except Swallows) the Island appeared to be devoid of any birds on Friday evening and Saturday morning between 5-9am. Birds then started to appear with a Spotted Flycatcher, a Blackcap and a Chiffchaff feeding in one tree in Bluebell Gully. The ringing then picked up with a Spotted Flycatcher, a couple of Chiffchaff and a Whitethroat caught. These birds appeared just in time to show to a group of 20+ people who had arrived by boat on a guided island tour. The baited crow trap then produced some birds, with 5 Jackdaws and a Magpie inside – although 2 of the Jackdaw and the Magpie managed to slip out when extracting them. A busy couple of hours quietened down after midday. Swallows were the only obvious persistent migrant, with birds flitting through much of the day with 9 ringed and a single House Martin, of which 4/5 passed through.

Whitethroat

On Sunday the conditions between 6-8am were ideal with full cloud cover and force 3 winds coming from the south west. The first two net rounds caught the majority of the day’s birds, with the second round producing a Spotted Flycatcher in the ‘Heli trap’, a Chiffchaff in the ‘Garden net’, and the ‘Withy net’, which was the best of the lot, produced 2 Spotted Flycatchers, 3 Blackcap and a Reed Bunting. A few more birds were picked up through the rest of the morning but, with the wind increasing, and switching back to westerly, many of the migrants seemed to have moved on.

Blackbirds

In the meantime, the habitat management progressed apace. Long hours were spent mowing the vegetation to maintain the short sward grass in designated areas, and keeping the pathways and net rides accessible. It takes a full week to complete all the mowing around the island and this takes place 3 times a year. Without this effort and work, moving around the island would very difficult with the dense cover of Red Campion and Bracken. It also maintains ideal habitat for the island’s diverse flora, and for many of the bird species (and the rabbits!).

Weekend Visit of 8th – 10th May

May 16, 2015 admin

A weekend party of three left a wet Donaghadee Harbour on Friday evening. It took the Copeland Shearwater RIB around 10 minutes to get to the South Jetty on Old Lighthouse Island. Once on the Island, the party made their way up to the Observatory building to get settled in for the weekend. The persistent rain limited the outdoor activities of the party for that evening. The Chris Bailey Hide provided a suitable refuge for seabird watching.

Early morning netting on the Saturday was quiet with no new birds ringed. The weather looked promising for the arrival of the roof working party that day. The weekend party were able to watch the chartered boat leaving Bangor on route to Donaghadee Harbour to collect the first of the roofing materials. This information was passed to the awaiting party on Donaghadee Harbour via mobile phone.

The chartered boat carrying the first of the roofing material arrived at the South Jetty around 10:45am. Some members of the work party arrived with the materials while other members remained at Donaghadee Harbour to assist with the next load.

Boat loaded with roofing materials

Once docked, the roof panels and building materials were unloaded from the boat and left on the foreshore. While the boat returned to Donaghadee to pick-up the next load, the work party on the Island started to bring the heavy materials up to the Observatory building.

Roofing materials on the foreshore

Wheelbarrows and other improvised lifting methods were employed to move the roof materials up to the Observatory building. This operation continued for two more boat trips. By the time the third and last boat was unloaded the water was up to the top level of the South Jetty. Another half hour or so and this jetty would have been unusable.

After a hard day’s work in the sun, it was time for the Saturday work party to leave. The Copeland Shearwater arrived at the East Jetty around 5:30pm to lift the remaining work party members. This had been a very successful day, with everyone working efficiently together to get an important job done.

Roof panels sitting outside Observatory building on Saturday evening

Sunday was overcast with strong winds as forecasted. Rope was used to secure the stacked panels together to prevent them from lifting. Three new birds were ringed that day, with one re-trap bird.

The weekend party left from the East Jetty on the Sunday afternoon. The strong winds made the return journey on the Copeland Shearwater a little choppy. Despite some mixed weather, the weekend was productive and enjoyed in good company.

Bird Summary

Over the weekend, reasonable numbers of Swallows were seen on (or perhaps moving through) the Island. The odd Swift, House Martin and Sand Martin were also spotted. Four Puffins were in the water just north of the East Jetty.

In total, three new birds were ringed (Willow Warbler, Chiffchaff and Spotted Flycatcher) with one re-trap (male Reed Bunting).

Weekend of 1st – 3rd May, 2015

May 8, 2015 admin

The weekend party of five arrived on the island on Friday evening full of anticipation for the Force 8-9 gale which had been forecast for Saturday afternoon into Sunday.

The couple of hours of daylight left on Friday evening allowed for the setting and baiting of traps and the erection of 4 nets in preparation for improved conditions – and therefore, the arrival of migrants – on Sunday.

As it turned out, we had a few hours on Saturday morning before the rain came, as forecast, in mid-morning. This lull allowed the trapping of 2 Hooded Crows and 2 Pied Wagtails in the Crow Trap and a Blackcap in the only reasonably sheltered net – NW Garden. Two Greenland Wheatears also arrived, but remained un-caught, despite a close encounter by one in the un-finished Gully Trap.

The wind gradually increased from an un-forecast (and unexpected) Force 1-2 at 06.30 on Saturday to Force 8-9 by lunchtime which, with face-stinging rain, effectively put an end to all out-door activities, except sea-watching from the Chris Bailey Hide. A significant Southward movement of 860 auks in an hour was recorded. Earlier in the day, 25 Puffins visited the Sound between the Observatory and Mew Island.

Gale-force wind and very heavy rain persisted all night, causing much surface water across the top of the island and significant “waterfalls” cascading down the rock faces close to the ‘Loo With A View’. The Old Well is brimming full.

When the wind and rain eased by lunchtime on Sunday, the 4 nets were opened – more in the need to dry them for packing away – and it became clear that a small arrival of migrants was occurring. Two Blackcaps, the first Sedge Warbler and a single Willow Warbler were caught in the short time available before departure. Single Whitethroat (the season’s first) and Skylark were seen, along with several more Willow Warblers. Meanwhile, an even larger Southward movement of auks was noted from the Chris Bailey Hide – 2800 in one hour.

On Sunday, the supply of water from the roof to the upper cistern which supplies our (almost) en-suite loo at the buildings was repaired.

All-in-all, despite the relative dearth of migrants, it was a very interesting and enjoyable weekend. The return journey to Donaghadee on Sunday – in thick fog – was also interesting!

The weekend ringing tally was as follows:

Hooded Crow 1 (+ 1 re-trap); Pied Wagtail 1 (+1 re-trap); Blackcap 3; Sedge Warbler 1; Magpie 1 and one re-trap each of Wren, Goldcrest and Reed Bunting.

CBO – weekend visit of April 24th – 26th

May 7, 2015 admin

8 species ringed – including the 1^st Blackbird and Sparrowhawk of the year.
Species list increases: Mediterranean Gull, Rook, Sedge Warbler and Sparrowhawk added.
Important work continues: mesh wire fitted to Gully Trap, and the jetties and cliff steps cleared

Nine people departed Donaghadee on board the Copeland Shearwater for the third weekend visit of 2015 on Friday the 24^th of April.

Although the forecast for the weekend was for strong north/north west winds, with rain until Saturday lunch time, the weather cleared by Saturday afternoon leaving some nice sunshine for the remainder of the weekend – although it was still cold in the brisk winds.

North/north west winds are not ideal for bringing spring migrants to the island, so those birds that were present may have arrived on the southerlies through Friday and remained throughout the weekend – waiting for the next break in the winds.

Despite the conditions, the team did manage to open a few mist nets on the east side of the island, which was relatively sheltered, and, in combination with the Heligoland traps, caught and ringed a few migrants.

Sparrowhawk – following the migration

As with the weekend previous, the crow trap, baited with bread, tuna and dog food, was again successful, catching two new Hooded Crows.

In total, 14 new birds were ringed with 2 re-trapped wrens.

4. Hooded Crow	2
5. Willow Warbler	4
6. Goldcrest	1
7. Goldfinch	3
8. Sparrowhawk	1
9. Wren	(2)

There was some great bird watching on offer, with particular interest in the island’s breeding species. CBO is a fantastic place to get up close to Black Guillemot, Eider and thousands of Manx Shearwater.

Four species were added to the 2015 bird list: Mediterranean Gull, Rook, Sedge Warbler and Sparrowhawk. The Med Gulls were initially picked up on call; flying in from the south, they settled on Mew Island amongst the Black-headed Gulls, allowing some good views through the telescopes.

Really good progress was made in the restoration of the gully trap. Both sides now have the wire mesh replaced and the first 5 metres of the roof was attached. It is planned – with just a little more effort – to have this trap in full operation by mid-May (perhaps in time for Whinchat & Cuckoo!).

Other tasks saw the jetties scrubbed down, and the Cliff-path steps were also given a little TLC having become overgrown and covered in loose gravel.

Spruced-up Cliff-steps!

Weekend Visit of April 17th – 19th

April 24, 2015 admin

Five species added to ringing list including, Pied Wagtail, Hooded Crow, Goldfinch, Blackcap and Reed Bunting.
Crystal clear night sky with great views of the International Space Station (ISS), Milky Way Galaxy, and moons of Jupiter.
New door frame fitted to Gully Trap.
First Puffin of 2015 seen.
Migration underway – notable movements (>40) of Hooded and Carrion Crows, and three Wheatear seen.

Sometimes the weather can be almost too good!

The second weekend team of 2015, covering Friday 17^th – Sunday 19^th April, certainly got spectacular early spring weather. The clear air in the mornings gave the eye a full sweep from Goat Fell on Arran in the North, to the Calf of Man in the south; a panorama from the old lighthouse stump which easily covered over one hundred miles. This is not, however, the weather that a ringing team necessarily want! When the conditions are so clear the birds often keep moving. Despite this, the weekend provided a steady trickle of birds through the nets and traps. Notable were the first Blackcap and Goldfinch of 2015, and an exciting catch of three Hooded Crow in the walk-in Crow-trap (feeding on old smelly cheese!). Other migrants included two Willow warbler, and singles of Chiffchaff and Goldcrest.

This photo shows the rarely seen underfoot of a Willow warbler – a vibrant yellow sole.

Several pairs of Reed Bunting breed on the island. A female was ringed on Sunday morning.

Regular visitors may bemoan the night-time loss of the familiar sweep of the beam from the Mew Island Lighthouse, recently decommissioned and replaced with a fixed flashing light. The night sky, however, somehow seemed enhanced. The Milky Way was clearly visible, and the team also tracked a four-minute transit of the International Space Station across the southern sky.

The spring flowers are really starting to show. The early double-flowering daffodils have already turned, but the narcissi probably have another few weeks left.

Clumps of Marsh Marigold can be found in wet areas.

Bird lists and migration logs are updated every day. Large numbers of crows – mainly Hooded, but also some Carrion – were noted on passage. The first Sandwich Tern was heard off Mew, and a Puffin dropped into the sound between Lighthouse and Mew Island on Sunday afternoon. Three Wheatear spent an hour on Sunday morning feeding around the front of the Gully trap.

CBO – First overnight Weekend Visit of 2015 (April 10th – 12th)

April 15, 2015 admin

Coastline clean-up removes 4 large bags of rubbish.
Species list increases: Peregrine, Water Rail, Manx Shearwater, Fieldfare, Wheatear, and Jack Snipe added.
Important work continues: mesh wire fitted to Gully Trap, and jetties spruced up for new season.

The CBO 2015 overnight manning season commenced on Friday 10^th April when a small team departed a blustery Donaghadee onboard our Rigid-Hulled Inflatable, the Copeland Shearwater.

Unfortunately the deterioration in the weather conditions over the weekend restricted the passage of migrants through the island, and hence the ringing return was zero. The team, however, still completed very useful work making the jetties safe by removing the winter growth of green weed, and made significant steps in getting the Gully trap ready for catching.

Seventeen species were added to the bird list, including Grey Heron, Peregrine, Water Rail, Moorhen, Jack snipe and Wheatear.

Depressingly, a beach clean-up around the island on Saturday afternoon removed four large bin-bags full of waste, including hundreds of plastic bottles, a coil of discarded rope, 5 gallons of used engine oil and various large lengths of plastic pipe….. everything excluding the kitchen sink. (In fact it could be argued that we got the kitchen sink too in the form of a plastic basin!)

Where does it all come from?

Kitchen sink!

Rubbish!

On a positive note, progress was made with the refit of the Gully Trap; wire mesh was fitted to one wall and all the support wires are now in place and fully tensioned.

Refit of Gully Trap

This weekend illustrates how important overnight visitors are to maintaining CBO as a functioning observatory. There is always something to do.

First trip of 2015

April 10, 2015 admin

Exciting start to new season – work progressing on refit of Gully trap.
Buildings and jetties intact after winter storms.
6 species ringed – 1^st bird ringed of 2015: Song thrush.
33 species sighted – including Snipe, Swallow, Chiffchaff, Willow warbler and Goldcrest.

On Tuesday 7^th April a team of seven volunteers paid the first visit of 2015 to the observatory – mainly with the purpose of preparing the Gully trap (our East-facing Heligoland walk-in trap) for the new season, but also to check over the buildings and jetties after the winter storms.

This was also the first outing of the season for our Rigid-Hulled Inflatable, the Copeland Shearwater.

The sea conditions from Donaghadee to Lighthouse Island were superb; flat calm, with the sky and sea merging into horizon.

After five minutes the team had their first sight of the island

Landing at the South Jetty just ten minutes after leaving Donaghadee, disembarkation was watched with interest from the cliff-top by a group of ten Shelduck. A dozen drake Eider were milling around the Gavney channel after a few females, and calling with their distinctive nasal mew.

The island is still looking very sparse and spring is yet to get a grip; the Bluebell carpet is just beginning to show and the thick patch of Narcissi around the front of the buildings is still waiting to flower.

Despite the recent spell of dry weather, conditions underfoot were soggy. Both the ponds were full to the brim.

Mew Island was resonating with the calls of Grey seals.

Early double-flowering daffodils were out above the Seat.

Philip Galbraith set a mist net in the garden, and worked the Wall and Heli Traps. On the first run of the Wall trap, a Song Thrush was caught and ringed – the first bird ringed in 2015.

After that, the Garden net provided a steady catch throughout the day. Six Goldfinch were caught and single Willow warbler and Chiffchaff.

Interestingly, the Chiffchaff had a pollen cone at the base of its bill – probably built-up during feeding in Africa and Iberia.

You can find out more about this at the following link

http://www.britishbirds.co.uk/article/unlocking-the-time-capsules-of-migrating-warblers/

Meanwhile, work progressed with the refit of the Gully trap. All the support wire was replaced and tensioned, and the trap is now waiting for a team to refit the wire mesh.

In addition to the birds, a group of eight Porpoise were spotted just beyond Mew, and a Peacock butterfly beside the wall trap.

In total 33 species were counted. The bird list is a follows:

Species sighted	Number counted
1. Cormorant	1
2. Gannet	6
