Colour Rings

A couple of Days out this week with 25 more Linnets ringed. Also 2 Juv Stonechats and a Meadow Pipit. A Willow Warbler was a surprise in the nets in the sand dunes at Smeale, i have not ringed many Warblers this year due to the wet weather.

A Greylag Goose was ringed at Ramsey Harbour, a new species for the ringing group, i was after a few Canada Geese but they would not come close enough. 

21 New Birds ringed in my Garden this week 

11 House Sparrows

6 Chaffinch

2 Goldfinch

1 Dunnock

1 Greenfinch

Also a couple of trips to Douglas for various things and 7 Herring Gulls Colour Ringed. 

 i took camera out this aft and noticed a Colour ringed Sanderling at Rue Point.We had a colour ringed bird sighted back in 2010 which was ringed in Ghana.

These birds are part of a study by the International Wader Study Group

The migratory journeys that sanderlings undertake twice a year belong to the longest known in the avian world. The length of the flights, the number and duration of stops between flights, as well the timing of the journeys will depend on the latitude of the non-breeding area and probably also that of the breeding area. Yearly variation in the circumstances during migration (both natural and caused by human) will further influence the success of the migratory flight and might thereby selectively favour sanderlings that winter closer or further away from the breeding area through their survival (see 1), as well as through reproductive output (see 2).

For long it has been suggested that sanderlings from Greenland and NE Canada mix with sanderlings breeding on the Taimyr Peninsula in Siberia during the non-breeding period. However, the evidence for Siberian sanderlings wintering in W Europe and/or W Africa is very poor. With our colour-ring scheme we hope to get a better view on the apparent mixing of both breeding populations.
