Eider flock migrating....
A few better shots of Common Eider from today at Landsort. The Common Eider, Somateria mollissima, is a large (50–71 cm body length) sea-duck, which is distributed over the northern coasts of Europe, North America and eastern Siberia. It breeds in Arctic and some northern temperate regions, but winters somewhat farther south in temperate zones, when it can form large flocks on coastal waters. It can fly at speeds up to 113 km/h (70 mph). Here at Landsort the birds can be seen migrating north to the breeding grounds, sometimes in great numbers...
The eider's nest is built close to the sea and is lined with the celebrated eiderdown, plucked from the female's breast. This soft and warm lining has long been harvested for filling pillows and quilts, but in more recent years has been largely replaced by down from domestic farm-geese and synthetic alternatives. Although eiderdown pillows or quilts are now a rarity, eiderdown harvesting continues and is sustainable, as it can be done after the ducklings leave the nest with no harm to the birds.
The Common Eider is characterized by its bulky shape and large, wedge-shaped bill. The male is unmistakable, with its black and white plumage and green nape. The female is a brown bird, but can still be readily distinguished from all ducks, except other eider-species, on the basis of size and head shape. This duck's call is a pleasant "ah-ooo." The species is often readily approachable.
Drakes of the European, eastern North American and Asia/western North American races can be distinguished by minor differences in plumage and bill color. Some authorities place the subspecies v-nigra as a separate species.
This species dives for crustaceans and molluscs, with mussels being a favored food. The Eider will eat mussels by swallowing them whole; the shells are then crushed in their stomachs and excreted. When eating a crab the Eider will remove all of its claws and legs and then eat the body in a similar fashion.
It is an abundant species, with populations of about 1.5-2 million birds in both North America and Europe, and also large but unknown numbers in eastern Siberia. Here in Sweden the bird is a familiar site along the baltic coast...
Alan Dalton post's birding diaries and original artwork from Sweden. Established in 2006, this now long running blog is now a complete overview of my birding experiences. As an artist I greatly enjoy sketching birds in the field and you will find a wide selection of that work here, from fieldwork to finished paintings. I am very passionate about my artwork and try to depict birds in their natural habitat, as I see them in the wild. My artwork is for sale and can be viewed at http://www.alandalton.net/
As regards to my photography, since 2008 I have used a Nikon D90 DSLR camera coupled with a Sigma 150-500mm OS lens for since March 2012 for bird photography, all previous images being digiscoped. Regarding sound recording, I have been usung a Telinga Stereo Dat Mic and parabol to record birds in the field, coupled to a Marrantz 661 digital recorder, a superb piece of kit. Interest in butterflies, dragonflies and damselflies has recently seen the accquisition of a Sigma 150mm macro lens.
