Gully trap – Copeland Bird Observatory

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.

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!

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.

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:
