During the course of World Osprey Week we’re following the spring migration of several different Ospreys. Here’s an introduction to each of them.
30(05) is a female Osprey who fledged from the Site B nest at Rutland Water in central England in 2005. She first returned two years later and then bred successfully for the first time in 2009 at a nest known as Site K. To date she has raised a total of eleven chicks.
In late January 2013 four members of the Rutland Osprey team travelled to Senegal to see her at her winter home. To find out more, click here. This spring 30 began he journey back to Rutland Water on 11th March. To read about her journey, click here.
Ilpo is an eight-year-old Finnish male Osprey. He was fitted with GSM/GPS transmitter in July 2014 at his nest in southern Finland. That year Ilpo began his autumn migration on 3rd September and spent the winter in Guinea.
Last spring Ilpo arrived back to his nest much later than usual; ten days after his mate, Helena. Sadly they failed to breed successfully, and so Ilpo set-off on his autumn migration much earlier than usual, returning to the same wintering site in Guinea. This spring Ilpo began the long journey back to Finland on 22nd March.
Seija nests in Lapland in northern Finland – making her one of the most northerly breeding Ospreys in the world. She is the mate of Tero (see below) and was fitted with a GSM/GPS transmitter on 26 July 2014. Her transmitter shows that she winters in the Ivory Coast each year. To read more about her latest migration, click here. This spring she has yet to begin her journey north.
After the manufacturer had repaired it, the solar -driven Microwave GSM/GPS satellite transmitter weighing 30 grams that had been carried by Helena, the Osprey that died at a Ukrainian fish farm, was fitted onto a male Osprey nesting near Kernaalanjärvi in Janakkala, Häme, southern Finland. The catching of the Osprey and the fitting of the transmitter were done by a taskforce from the Osprey Foundation including its director, Juhani Koivu, ringer Harri Koskinen, and bird-watcher Matti Aaltonen, who gave them a lift in his boat. Pertti Saurola ringed three healthy fledglings during the action. Further, the American Osprey guru Alan Poole came along to study Finnish Osprey research. The unringed male Osprey, weighing 1,395 grams, gained an aluminium ring M-68134 on his right talon and a red ring CP on his left, and the name ‘Alan’ after the international visitor. After spending the winter on the coast of Gabon, Alan set-off on migration this spring on 13th March.
Belle is a four year-old female Osprey from Massachusetts in the United States . She was satellite-tagged by Rob Bierregaard as a fledgling at a nest on Lake Tashmoo on Martha’s Vineyard’s north shore on 28 July 2010. She winters in Brazil near the Madeira River at the southern edge of the Amazon rainforest. This spring she began her northward migration on 8th March.
We are very grateful to Rob Bierregaard for allowing us to track Belle during World Osprey Week. To find out more about Rob’s Osprey migration studies in the United States, check out his website.
Staddler is the breeding male at a nest on a 10 foot high platform in the saltmarsh at Seabrook Harbor in New Hampshire. Ospreys originally nested on top of a duck blind before local resident Dave Weber installed a platform several years ago. Staddler is named after the short wooden stakes which dot the saltmarshes of New England. These Staddles were used to hold platforms where harvested saltmarsh grass was stacked to dry. The weather-worn stakes still persist today and now provide perfect feeding perches for Ospreys.
Staddler was tagged by Iain MacLeod and Rob Bierregaard in 2015 and migrated to Brazil for the winter. He returned to New Hampshire last spring and reared two chicks. Staddler is now back at his wintering site in Brazil – but should leave any day. To find out more click here. We are very grateful to Iain MacLeod of the Squam Lakes Natural Science Center for allowing Staddler to be included on the map.
Previous WOW Ospreys
Sadly we have lost contact with some of the Ospreys that we have followed previously during WOW.
Blue XD is a male Scottish Osprey and was ringed as a two-year-old at Rothiemurchus Fishery, Scotland on 12th August 2000. Roy Dennis then re-found him as the breeding male at a nest near Carrbridge in 2002. He is regularly seen fishing at Rothiemurchus Fishery as well as on the River Findhorn near Tomation and at Lochindorb. Last autumn Blue XD migrated to his usual wintering site beside the Casamance River in southern Senegal, but the satellite data suggests that, sadly, he died there in February. To find out more, check out Roy’s blog here. Many thanks to Roy Dennis for allowing us to track Blue XD as part of WOW.
Helena was Ilpo’s mate and was also fitted with a GSM/GPS transmitter in July 2014. That autumn she migrated to Nigeria. In spring 2015 she set-off on her northward migration on 16th March and arrived back at her nest in Finland on 14th April. Sadly she failed to breed successfully, and then died on her autumn migration after getting tangled in nets at a fish farm in Ukraine. You can read more about Helena’s story here.
Tero is a male Osprey from a nest in Lapland in northern Finland. He was fitted with a GSM/GPS transmitter on 26 July 2014. Tero set-off on his autumn migration on 29th August and took two months to reach his wintering site on the coast of Kenya. To read more about his migration, click here. In summer 2015 he returned to Lapland and raised two healthy chicks with Seija. After again spending the winter in Kenya, he set-off on his spring migration this year on 28th March and again completed the long migration to northern Finland. Unfortunately his transmitter stopped sending signals late in the summer.
Donovan is a male Osprey who nests near Tilton in New Hampshire in the United States. He was fitted with a satellite transmitter in May 2013. To find out more, click here. After spending his winter in Venezuela, Donovan set-off on his spring migration last year on 9th March and arrived back at his nest on 2nd April. He and his mate reared two healthy chicks. He then returned to Venezuela but his transmitter stopped sending data in November. To read more about Donovan, click here.
We are very grateful to Iain MacLeod of the Squam Lakes Natural Science Center for allowing us to follow Donovan as part of WOW.
North Fork Bob
North Fork Bob was a male Osprey from New York in the United States. He was trapped and fitted with a satellite transmitter by Rob Bierregaard near Mattituck on Long Island on 1 May 2010. Bob spent his winters in the Guianan Shield highlands of southern Venezuela on the Ventuari River. To read more about his migrations, click here. In spring 2015 Bob arrived back at Long Island on 21st April and went on to breed successfully for the first time. Very sadly, though, he then died in Florida on his autumn migration.
We are very grateful to Rob Bierregaard for allowing us to track Bob during WOW. To find out more about Rob’s Osprey migration studies in the United States, check out his website.
