A friend wishes to know what this wader she saw at frampton Marsh today is:
Nearest match I can think of is a juvenile Ruff or something......

You're right, its a Ruff. The black feathers on the lower breast and the bi-coloured bill make it an adult male moulting out of breeding plumage. You should report the colour rings, then you'll maybe be able to get detailed info on this bird. |

The form to report colour ringed birds is online at http://blx1.bto.org/euring/lang/pages/c ... @snm.ku.dk Fill it in and you will get information about where the bird is from etc... You can then post it on the forum to let us all know. It can take a couple of weeks before you get the information back.......... BTW great photo Andrew |

Thanks to Jo Fisher for forwarding on the details of the above bird.... Details on the colour ringed Ruff are as follows: Colorcode: B3WRYY Name Jaap Strikwerda 2nd Ringnr: 1508488 Date Catch: 19-3-2009 Catching Location: Workum, Workumerbinnenwaard- Noord The Netherlands 52.59.28 N 05.24.08 E Sightings of this bird: Date(d/m/y Location Observer 2nd Observer 3rd Observer 21-3-2009 Workum, Workumerbinnenwaard-Noord Marianne McGhie Katharine Bowgen The Netherlands 52.59.28 N 05.24.08 E 22-3-2009 Workum, Workumerbinnenwaard-Noord Jan Kramer The Netherlands 52.59.28 N 05.24.08 E 23-3-2009 Workum, Workumerbinnenwaard-Noord Pedro Lourenco The Netherlands 52.59.28 N 05.24.08 E 25-3-2009 Workum, Workumerbinnenwaard-Noord Katharine Bowgen Tamas Kiss The Netherlands 52.59.28 N 05.24.08 E 25-3-2009 Workum, Workumerbinnenwaard-Noord Katharine Bowgen Tamas Kiss The Netherlands 52.59.28 N 05.24.08 E 25-3-2009 Workum, Workumerbinnenwaard-Zuid Theunis Piersma The Netherlands 52.58.23 N 05.25.01 E 6-4-2009 Stavoren, Noordermeerpolder Marianne McGhie Lucie Schmaltz The Netherlands 52.53.32 N 05.23.14 E 19-7-2009 Boston, Frampton Marsh Jo Fisher United Kingdom 52.56 N 00.01 E dinsdag 29 september 2009 Pagina 1 Below and on our website you can find more information about this project and other (bird) research at the University of Groningen and read the latest Ruff-Newsletter (April 2009): http://www.rug.nl/biologie/onderzoek/on ... e/onderzoe k/researchStudies/migratimmune Jos Hooijmeijer ----------------------------------------------------------- RESEARCH OUTLINE Colour-ringed Ruffs and Black-tailed Godwits In the spring of 2004 the University of Groningen, (The Netherlands), started a long-term research-project on the relationship between breeding range and migration-patterns in waders. There seems to be a general pattern that arctic breeders predominantly spend the winter in marine habitats, whereas species breeding south of the tundra desert belt tend to winter in more freshwater habitats. The driving force behind this is supposedly the ability of a species´ immune system to deal with diseases, which are more likely to occur under warm/ freshwater conditions. Red Knot (Calidris canutus) and Bar-tailed Godwit (Limosa lapponica) are examples of the arctic/marine species-group, whereas related species as Ruff (Philomachus pugnax) and Black-tailed Godwit (Limosa limosa) are representatives of the opposite strategy. The Black-tailed Godwit is one of the few bird species for which the Netherlands has an important international responsibility, because about 80 % of the EU-population breeds here. Numbers have declined strongly during the last few decades, mainly as a consequence of agricultural intensification. There is a large amount of background knowledge on population trends in different parts of the country, but apart from some aspects, most of their ecology is not well known. We are interested in timing and transition from migration to breeding, the variation in breeding plumage, mate choice, immuno-competence, chick- and adult-survival, etc.. We hope that the outcomes of our research will also contribute to the conservation of this beautiful species. Ruffs are close to extinction as a breeding bird in The Netherlands, but large numbers stopover in the Dutch grasslands during north- and southward migration. Although peak-numbers are quite well known, there is little information on staging-time. This makes it difficult to estimate the total population size of Ruffs using the Dutch meadows during spring migration. Ruffs staging in The Netherlands fan out to an enormous boreal breeding range with recoveries as far away as eastern Siberia. Most Ruffs spend the non-breeding season in West Africa, but some winter as far north as The Netherlands. Although there is evidence that males and females use different flyways, no evidence exists for population structuring of the kind known in many other long-distance shorebirds. This is surprising, as the timing of migration and reproduction varies strongly between different parts of the range. Furthermore, we will try to unravel the mysterious third mating-strategy in Ruffs: the faeder. In order to be able to address these questions, a colour-marking programme was started in 2004. Until now more than 4000 Ruffs and 450 Black-tailed Godwits were colour-ringed, of which we have received in the past years 6600 and 3500 sightings respectively from over 300 observers and from more than 175 locations in 18 countries! We aim to continue colour-marking birds in the coming years. Both species wear a metal ring, 4 colour-rings (2 per leg) and an additional colour-flag (colour-rings and flag without inscriptions). Used colours are: yellow, blue, red and white. The metal ring is not a part of the code and therefore of no importance. We hope that many birdwatchers will take the effort to send in their observations of colour-ringed birds. In return we will inform you at least once a year about the research-proceedings and the bird(s) you have seen. Besides the exact position of flag and rings we are of course also interested in the re-sighting date and place (if possible with co-ordinates). Supplementary information on group-size, behaviour, habitat and the number of birds you checked for rings is also very welcome! ~~~~~~~~~ |
