Willow warbler – Copeland Bird Observatory

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.

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.

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.

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:
