Copeland Bird Observatory 9th-11th May

On Tuesday the 9th I headed out to Copeland Bird Observatory for my first mid-week stay accompanied by Laurence from the Belfast and Down Ringing Group.  The trip had been arranged to accommodate a work party of 10 from a local NGO but they unfortunately had to cancel.  The forecast looked rather decent and I like to get out to the island this time of year so we decided to press ahead anyway. 

Whitethroat

The said forecast was as predicted for the two night stay with hardly a cloud in the sky and some very warm weather.  The winds weren't fantastic for migration with northerlies on Saturday morning/afternoon and easterlies for the rest but a number of birds still passed through.  The island is dry as I have ever seen it following almost 3 weeks without rain.  I had said something very similar in a post this time last year but it was much drier this time with the pond down to a muddy sludge and cracked earth all over island.  The island still looks fantastic with the millions of flowers of Bluebell, Crab Apple, Marsh Marigold, Red Campion, Sea Campion, Scarlet Pimpernel and Thrift to name but a few.   

The image above shows the remaining mud in the garden pond and the keen eyed will notice a couple of Swallows and a Pied Wagtail in the net which I put up to take advantage of the dozens of Swallows swooping low over the surface. 

Pied Wagtail

Over the weekend hirundines were the most conspicuous migrants with 175+ Swallows passing through (plus a few resident birds) and 15+ House Martins.  14 Swallows were captured and a single House Martin which was the first of the year.  Swifts made an early dash through on Wednesday morning with at least 6. 
I didn't pay much attention to the action offshore but certainly on Sunday there were obviously fish on the move with lots of Razorbills, Guillemots, Gannets and gulls working the shoals (plus a few angling boats).  The first Common Terns of the year arrived on Wednesday, with even more the following day plus the first Arctic Terns while Sandwich Terns were present throughout.  The Puffin numbers reached 28 with a number visiting the burrows and Black Guillemots hit 66.   

House Martin

The breeding birds are very busy with many of the Eider, Herring Gulls and Reed Buntings incubating their first eggs and the likes of Blackbird, Meadow Pipit, Stock Dove and Rock Pipit feeding chicks.  It will be a busy few months with the Black Guillemots, Common Gulls, Fulmars, Lesser Black-backed Gulls and Swallows joining the mix and with any luck the Arctic/Common Terns, Black-headed Gulls and Puffins will have a successful year.  A retrap female Blackcap and a skulking singing male Blackcap suggest they may breed once again and hopefully the singing male Sedge Warblers will hang around after a few years absence. 
Another species new to the ringing list and species list for the year was Whitethroat with three caught over the weekend with a further 3 Sedge Warbler and 3 Willow Warbler.  Corvids were on the move with plenty of Hooded Crows, Jackdaws and two Carrion Crow passing over.  Seven Jackdaw stopped by for a quick feed in the crow trap and were duly ringed. 


Water Rail

A few other nice captures included a smart looking retrap Water Rail, the 8th Wheatear of the season (one of three present) and a late Song Thrush.  Non-avian sightings were made up of 40+ Green-veined White butterflies plus the first Red Admiral of the year. 
We got a little work done on Saturday afternoon when we patched up the holes in the crow trap (which provided immediate dividends in the Jackdaws) and started a bit of grass cutting which is a monumental task.

My personal CBO patch list for the year is up to 76 species which is around my usual year total of 75-80 with the autumn still to come.  The Observatory as a whole is having a very decent season in terms of variety and has reached 93 species with the addition of Whinchat and Spotted Flycatcher in the weekend past.  To keep up to date with the species list you can check the CBO website at  - http://www.thecbo.org.uk/birds/2017-species-list/

I'm off to the Observatory again this coming weekend with a party of 12 people, 10 of those ringers.  Migrants at this time of year are very thin on the ground with the last trickle of tardy birds passing through but it does produces some of CBOs best spring rarities.  Hopefully with a bit of luck there will be a few birds to share around but the northerlies don't look promising. 
I head off to Italy for a few weeks the following weekend so activity will be limited until mid June, just in time for Sand Martin season.

Copeland Bird Observatory 15th - 17th May

Steve and I headed out on a ringing trip to Copeland Bird Observatory for the weekend (15-17/05/2015) in the hopes of catching a few spring migrants.  The Observatory is located on Lighthouse Island which is part of the Copeland Islands, off the County Down coast in the Irish Sea.
A group of 5 of us arrived on the Island on Friday evening and Steve and I set about setting and furling nets and opening three of the Heligoland traps and the Crow trap.

Saturday morning @ CBO

The weather over the weekend wasn't ideal with constant west winds blowing at around 20mph but we did manage to avoid much of the rain and had some nice sunny weather.  The conditions weren't exactly fantastic for catching birds but the east side of the island remained fairly sheltered.  The winds on Sunday morning switched to South-west for a few hours, which are thought to be the best direction for bringing migrants to the island in spring and they did bring us a handful of nice birds.

Breeding 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.  We also found the nests of Oystercatcher and Blackbird with eggs and seen two Eider chicks.  The Fulmars were sitting on the cliff ledges and a pair of Rock pipits were bobbing about close by.  The pair of Starlings in the workshop were busy feeding chicks and the Swallows have been checking out the usual nests.  We caught and ringed two Swallows on the Friday evening, who had flown into the Ringing Laboratory looking for nesting sites.  Many of the other resident breeders remained inconspicuous, so may be sitting on eggs e.g. female Reed Buntings, Shelduck, Stock Doves.  The Arctic terns have started to arrive back with c180 birds but there are plenty more to come and set about to breeding.  We also had 4 Puffins knocking about, with 2 sitting among the decoys and a pair of Red-breasted Mergansers on the sound between Lighthouse Island and Mew Island.

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 and we caught a Spotted Flycatcher, which is a first for me and a couple of Chiffchaff and a Whitethroat.  These birds appeared just in time to show 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.  Steve also caught a Pied Wagtail in a Potters trap, so it was a busy couple of hours but it 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.

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 days birds, with the second round producing a Spotted Flycatcher in 'Heli trap', a Chiffchaff from the 'Garden net' and the 'Withy net' was the best of the lot with 2 Spotted Flycatchers, 3 Blackcap and a Reed Bunting.  We picked up a few more birds through the rest of the morning but the wind had picked up and switched back to a westerly and many of the migrants seemed to have moved on.

All in all it was a really good weekend particularly because I caught up with my target species for the year - Spotted Flycatcher and caught another new species in the form of an Eider duck.  Steve also did well with 4 new species ringed - Spotted Flycatcher, Jackdaw, Whitethroat and House Martin, taking him past 40 species in preparation for his C permit application.
Another few trips will be arranged for autumn migration and perhaps a trip in mid summer to work on the Manx Shearwaters and other breeding birds.
