2011-12-11Recovery of a Barn Owl ringed in DenmarkA freshly dead Barn Owl was found on 2 December in Mörlunda in the province of Småland. It was probably killed by a car and it was ringed as a chick in the area of Brönderslev in northern Jutland 57 days earlier, on 6 October. The distance between the ringing site and the finding site is 371 km in an eastern direction. The Barn Owl is nowadays a rare bird in Sweden and breeds only occasionally. Only 29 nestlings have been ringed during the period 2000 — 2011. The species is more common in Denmark and according to information from the ringing centre in Copenhagen, 5883 Barn Owls were ringed in Denmark during the period 2000 — 2010. The cold winter 2009/2010 affected the population very much and the population has decreased heavily during the last two years.
During the period 2000 — 2010, 16 Barn Owls have been sent to the Swedish Museum of Natural History after being found dead in Sweden. In two cases the owls were ringed (both in Germany) and the recoveries show that first-year birds can perform movements over longer distances. For example one Barn Owl found in the middle of January 2001 in the province of Uppland, central Sweden, was ringed as a chick in eastern Germany in the year 2000 and the distance between the two sites is more than 900 km. Another example is a Barn Owl ringed in Denmark and found in bad condition on a Norwegian oil ship between Stavanger and Orkney on 29 December 2010, six months after it was ringed in Denmark and 560 km from the ringing site. 2011-12-04
Ringed Pallid Harrier observed in SkåneA juvenile Pallid Harrier was observed on 18 September at Foteviken, in the province of Skåne. It was ringed and from photos it was possible to read the text C4F on a white colour ring. This bird was ringed as a nestling in the area of Kajana in central Finland on 23 June 2011. Pallid Harriers have been found breeding at several places in Finland this year and Pallid Harriers have been reported more frequently than normal also in Sweden. The number of Pallid Harriers in the raptor counts at Falsterbo this autumn is 43, while the mean autumn number for the period 1973-2010 is two.2011-11-20
Ringed Gannet found at GotlandA ringed bird was found dead on the beach at Fårö, north of Gotland, on 6 November. It was ringed with a British ring and reported directly to BTO. The bird was a Gannet ringed as an adult bird on the Great Saltee Island, SE Eire, on 17 July 2010. An adult Gannet, probably one individual, has been observed around Gotland during summer the last two years. Gannets are rare in the Baltic and therefore it could have been this bird that now was found dead. An adult Gannet was, however, observed at Gotland at the time of ringing, which indicates that the bird found dead is another individual.2011-11-01
Longevity record for Black-tailed GodwitRemains of a Black-tailed Godwit ringed as a nestling on 22 May 1993 at Rinkaby ängar nearby Hammarsjön in the province of Skåne was found on 30 May this year in a nest box for Peregrine Falcons on Kristianstad water tower. The remnants had probably not been in the nest box for more than two weeks. The Black-tailed Godwit reached the age of 18 years which is much older than the previous longevity record of 12 years and 1 month. Both leg and ring was sent to the Bird Ringing Centre and a DNA sample has been stored in the collection of the museum. Previously there was only one sample of DNA from a Black-tailed Godwit. The oldest known Black-tailed Godwit in Europe was ringed in Britain and the ring number was read without the bird being trapped at the age of 23 years and 7 months.2011-10-20
Swedish ringed Scarlet Rosefinch observed on Fair IsleIn early September a colour ringed juvenile Scarlet Rosefinch was observed on Fair Isle in a flock of 15 birds. This bird was ringed at Ringenäs, close to the city Halmstad on the West Coast, on 25 August. The distance from Ringenäs to Fair Isle is about 900 km in NW direction. Rosefinches normally migrate SE to wintering sites in the southern part of Asia. There are up to now 78 recoveries of Rosefinches ringed in Sweden but only one long distance recovery, in Armenia, where a bird was trapped in May 1975. Information about this recovery and the Wryneck found recently in southern Britain has been included in the BTO Bird Ringing blog . 2011-10-18
Second recovery of Wryneck in BritainA Wryneck ringed as a nestling at Svinnö in the northern part of the province Uppland this summer was found dead in late September in a garden of Northam in Devon in southwest Britain. The finder declared that it probably had been killed by a cat. This is the second recovery of a Swedish ringed Wryneck in Britain. The former was reported from southern Britain in early September 1998 and even then a cat was the probable cause for the recovery. Other recoveries show that Wrynecks ringed in Sweden, move on a broad front through Europe in autumn to wintering areas, which are located in tropical West Africa.2011-10-04
Osprey faithful to autumn stopover site in France An Osprey ringed as a nestling in 2005 in the province of Uppland is for the second autumn observed in Le Morbihan, France. This year the ring number was read on September 9 from a hide while the Osprey was eating a fish. Last year, the ring number was read by the same observer on September 11. Le Morbihan is a large sheltered bay with many islands located south of Vannes in Bretagne. Ospreys move on a broad front through Europe to wintering areas in West Africa and appear to be faithful to some individual stopover sites along the way to which they return each year, as this recovery shows. The track between the resting areas may however vary from year to year partly due to weather conditions.2011-05-29
28 years old Sandwich TernA Sandwich Tern ringed as a chick at Bergkvara, SE Sweden, has now in May been sighted alive and probably breeding in a colony on the Danish island Hirsholm, northern Jutland. This bird has been sighted in this colony several times since 2005 and it also had the previous Swedish longevity record, now increased by one year. The European longevity record is hold by a Sandwich Tern ringed in Britain reaching an age of 30 years and 9 months. The colony includes about 1600 pairs of Sandwich Terns and within a special project rings are read from a distance. About one out of seven birds are ringed and they are observed when visiting a place where they are bathing and cleaning their feathers.2011-03-21
Golden Eagle sighted in PolandA Golden Eagle ringed as a nestling in the province of Hälsingland 2009 has been sighted in Poland during the period 20 February — 3 March 2011. It is rare that Golden Eagles born in Sweden move south of the country. We have earlier only two such recoveries, one from the province of Norrbotten found in Belarus in 1993 and another from the province of Västerbotten found wounded in southeastern Poland in 2008. Golden Eagles in Finland regularly migrate longer distances in a southeastern direction. Compared with the two earlier recoveries, this one was born more to the south and the finding place was also clearly more to the west. The question is whether the eagle initially moved south east of the Baltic or if it performed a sea crossing.2011-03-16
A 60 years old albatrossProbably the oldest known wild bird in the world has recently been sighted. It is a Laysan Albatross ringed as a breeding bird in 1956 at the Midway Atoll in the Pacific. At ringing it was estimated to be at least five years old and when it was sighted in March 2011 at least 60 years old. It has worn out several rings and is now wearing ring number five. It has been named Wisdom and in spite of its age it was seen with a chick. Read moreAbout four hours after the earthquake off Japan last week a tsunami flooded Midway and killed thousands of adult and chick Laysan Albatrosses. It was, however, recently reported that both Wisdom and its chick survived the tsunami.A Royal Albatross in New Zeeland is known to have reached an age of at least 58 years.2011-03-14
Black-headed Gull faithful to wintering site in Ukraine A Black-headed Gull ringed as a first-year bird in October 2004 in the city of Malmö, southernmost Sweden, has been sighted the last three winters in Ukraine. The first sighting was on 17 November 2008. It was sighted between 2 November and 21 December the following winter and the last winter on 31 January 2011. The place where it was observed is Luzanovka, at the coast of the Black Sea, just north of the city of Odessa. We have close to 16 000 recoveries of Black-headed Gulls, but this is the only bird that has been found in Ukraine. Black-headed Gulls normally migrate SW and many birds from Finland and Western Russia pass Sweden on their way to and from Western Europe. It is possible that this is a bird of a more eastern origin that moved a little bit too far during its first migration and later on returned to a more normal wintering site further east. The distance from Malmö is 1587 km.2011-03-01
Curlew Sandpiper recaptured in MauritaniaA Curlew Sandpiper ringed as a first-year bird at Ottenby Bird Observatory, SE Sweden, on 19 September has been recaptured by Dutch ringers on 5 December in Mauritania. The area where it was recaptured, the Banc d´Arguin National Park, is a very important coastal area for birds with large number of waders wintering or resting during migration. This species breeds on the Siberian tundra in the area of Taimyr and pass Sweden during migration. The distance from Ottenby to the place in Mauritania is 4856 km and we have another Curlew Sandpiper ringed in Sweden recaptured in the same area in 1973.2011-02-08
Longevity record for White-tailed Sea Eagle A Sea Eagle ringed as a nestling on 5 June 1979 at the coast in the province Uppland was observed at a feeding site for Sea Eagles close to the river Dalälven on 30 January 2011. This bird has been observed several times over the years and is now close to 32 years old. Based on the age at ringing it is known that it was hatched in the end of April. This is probably the oldest White-tailedSea Eagle in the world so far.2011-01-20
Bullfinch recovered in the Netherlands A Bullfinch was found dead after collision with a window on 19 January on the island Vlieland in the Netherlands. It was ringed in October at the bird observatory at Hammarön in the province of Värmland in western Sweden. Bullfinches are normally moving only short distances, but the unusually cold winter might have forced this bird to move further south. We have earlier two recoveries of Bullfinches in the Netherlands (1971 and 1972). With the exception of a bird found on Fair Isle, this is the westernmost recovery of a Bullfinch ringed in Sweden.2011-01-04
Storm Petrel recaptured in OrkneyA Storm Petrel ringed on 8 August 2009 on the island Måseskär on the Swedish West Coast has one year later been controlled by ringers at Tres Ness on the island Sanday, Orkney. The Storm Petrel is rare but regular along the Swedish West Coast and 63 birds have been ringed there until 2009. One of these was controlled a year later by ringers in northernmost Scotland and three have been controlled in Norway. One Storm Petrel has made the opposite movement and was ringed at Tres Ness in August 2006 and controlled at Måseskär nine days later! The distance between the two sites is 808 km.
