The first Barnie causes a twitch

There are very few reports of UK ringed birds in America and the majority are Manx Shearwater (8) and Great Skua (3). We have also had single reports of White-fronted and Canada Goose, Turnstone, Kittiwake, Arctic, Roseate and Common Tern.

Yesterday we received an email from Jack Rothman informing us of the first British ringed Barnacle Goose to be recorded in America! Barnacle Geese in North America are rare anyway but one with a known origin is brilliant. This bird was seen at Orchard Beach, Bronx which is 5204km from where it was ringed.


Barnacle Goose 1291347 was ringed by Steve Percival on 13/11/2002 and was seen frequently on Islay until March 2005 when it disappeared. One of its parents and a sibling where ringed at the same time and are still seen around Islay.

Thanks to Keith Michael for finding the bird and Jack Rothman for letting us know and also for the photo.

Redpoll... but which one?

Winter is a good time for ringers to be catching Redpoll, as you an tell from the previous post.

The plumage and biometrics of Redpoll are looked at very closely by ringers which need to separate them into the current 3 species, Lesser (the most commonly caught Redpoll), Common Redpoll and Arctic Redpoll. Sorby Breck Ringing Group were out ringing and they came across something very interesting.


This is actually a Lesser Redpoll that had already been ringed by the group. Interestingly when it was ringed it looked like any other Lesser Redpoll and lacked all this white. This condition is likely to be Vitiligo, which means this bird could get whiter with every moult but start out looking like a normal brown Redpoll. This condition is most commonly seen in Blackbirds and Jackdaws but has also been recorded in Redpoll.

The graph below shows the number of Redpoll ringed in 2009 by month.

Many thanks to Geoff Mawson (for the photo as well), David Williams and John Wint for letting us know.

A first for a Common Redpoll

The Redpoll complex has always provided a few challenges with identification for birdwatchers but being able to take measurements and ring individual birds provides much more quantitative information.


Pete Smith from Wintersett Ringing Group was ringing at Wintersett Reservoir, Wakefield on 15th November and had a great ringing session. He caught 53 Lesser Redpoll (above) and 14 Common Redpoll, 2 of which were already ringed! One was ringed at Kilnsea, East Yorkshire on 21/10/10 (104km in 26 days) and the other was wearing a Norwegian ring!

We have had very few recoveries of Common Redpoll (5 from the UK and 2 from The Netherlands) so this is the first from Norway!

Thanks to John Wint and Pete Smith for letting us know and Tommy Holden for the photo.

Colder temperatures bring in the birds

Every week we receive reports from Ringing Schemes all over Europe and today we have received a batch of records from Stavanger (Norway).

This included 2 Norwegian ringed Robins, both caught by UK ringers, one at Kilnsea, East Yorkshire (ringed 170 days before in Rogaland, Norway) and the other at Hartlepool, Cleveland (ringed 18 days before in Buskerud, Norway).


With this cold weather Brambling should be quite settled in the UK now and one such bird was controlled at Spurn Point, East Yorkshire which was ringed in Sept 2009 in Rogaland. On the other end of the seasonal scale a Chiffchaff was controlled also at Kilnsea, East Yorkshire which turns out to be the 8th from Norway! It was ringed 69 days before (23.7.2010) at Grimstadvatnet, Hareid, More og Romsdal.

And finally a Kestrel was reported freshly dead and very thin at Swanley, Kent on 19th Sept 2010 which had been ringed as a chick on 30 June 2010, 1326km away at Galasflota Nord, Hedmark, Norway.

Thanks to Stavanger and Dawn Balmer for the photo.

New Bird Observatory in the Gambia

Volunteer ringers from the UK have just returned from their first trip to the Kartong Bird Observatory, to help understand bird demography in the Gambia. During the 11 day trip more than 800 birds were processed and measurements taken. The majority of the birds ringed were African but there were some Palearctic migrants which were just arriving including Blackcap, Garden Warbler, Olivaceous Warbler, Yellow Wagtail, Sedge and Reed Warbler.


During the nights it was very dark, due to the new moon and provided great lamping conditions for Long-tailed Nightjar, Painted Snipe, Senegal Thick-knee and Spur-winged Plover. Local bird guides and birders will be able to take part in reporting leg flagged Spur-winged Plovers throughout Gambia and the movements of the whoosh netted Hooded Vultures will be very interesting (below).



Ringing demonstrations were run mid week to introduce the local school children to bird conservation and it was received very well with many fascinated faces. Some notable birds were Yellow-crowned Gonolek (pictured), Levaillant’s Cuckoo and Blue-breasted Kingfisher (1 of the 6 species of kingfishers caught).


Future annual expeditions will provide more valuable data, with the next trip being March 2011. Maybe more new birds will be added to the Gambian list like Cassin's Honeyguide as on this occasion.
