This is a shoveler video from England.

I was privileged to see these beautiful ducks; in western Europe, where they are not rare; and in Svalbard, where they are very rare.

Abstract:

An ecological study of the Northern Shoveler Anas clypeata in the wetlands of the Guerbes-Sanhadja eco-complex (Skikda, north-eastern Algeria) which was performed during wintering season (from September 2012 to March 2013) showed that the species was regularly wintering in these ecosystems during the seven months of observation. The highest numbers were recorded during December 2012 (1943 individuals) at Garaet Hadj-Taher, although this wetland was the last to be colonized if we compare it to other wetlands. Garaet Hadj-Taher hosted more than half of the wintering population of the Northern Shoveler in the Guerbes-Sanhadja eco-complex. Sleeping activity (diurnal resting) dominated over other diurnal behaviours of this Anatidea at Garaet Hadj-Taher…

Garganey, pintail, and other birds


Wigeons, on 21 March 2015

21 March 2015. Though it was officially the first day of spring, it was cold and windy. The male and female wigeons in nature reserve De Wilck, depicted in this photo, apparently thought the weather was still too winterish for migration back to eastern and northern Europe.

Before arriving at De Wilck that morning, we had first gone to Zaans Rietveld reserve.

This is a Zaans Rietveld video.

Zaans Rietveld biodiversity: here.

Black-tailed godwits flying about and calling. Grey lag geese. Wigeons here as well.

A chiffchaff sings. The first time I hear that sound this year.

Two oystercatchers.

Scores of barnacle geese grazing. A northern lapwing.

Lesser celandine starts flowering.

A hare.

A dunnock sings.

A great egret flies and lands.

A reed bunting signs.

A grey heron flying.

A curlew flies over a meadow. On the meadow: herring gulls, mute swans and two shelducks.

A chaffinch sings.

A dead mole, lying in the grass.

A singing greenfinch.

In a shallow lakelet: avocets. Black-headed gulls. Teal. And, resting on a bank, a rare teal relative: a male garganey.

Then, we continued to De Wilck. Hundreds of wigeons. Also, a male pintail.

Finally, to the Amaliahut hide.

Then, she took to the water with her mate.

Habitat use and distribution of the Ruddy Shelduck (Tadorna ferruginea) in the wetland complex of Oued Righ, Algerian Sahara

Abstract:

Our study conducted from August 2007 to May 2011 in the main wetlands of the Oued Righ complex (Eastern Sahara of Algeria) aimed to study the habitat use and distribution pattern of the Ruddy Shelduck Tadorna ferruginea. As the species was recorded breeding at most sites of the wetland complex, it was given the resident breeder status, which differs from the one it had previously. The maximum number of Ruddy Shelducks (284 individuals) was recorded each year during the winter season (second half of December). The Ruddy Shelduck (60% of population) shows preference for shallow middle-sized salt ponds with a high proportion of open…

Long-tailed duck, new species for Dearborn, USA


This is a long-tailed duck video.

From the blog of the Rouge River Bird Observatory at the University of Michigan-Dearborn in the USA:

Monday, March 2, 2015

Dearborn adds another new species!

On 1 March 2015, Larry Urbanski found a Long-tailed Duck (Clangula hyemalis) in the Rouge River near the Ford Rouge Plant. There is a photo attached to his eBird checklist (sign in may be required for one or both links) and the bird appears to be a male.

Mike O’Leary and I attempted to locate the bird this morning, and found a Long-tailed Duck that appears to be a female, or at least doesn’t look like the bird found yesterday. …

Long-tailed Duck is the 260th species on the Dearborn list.

Most of the Rouge River is still frozen solid. The areas in the Ford Rouge boat slip and adjacent waters stay open all year. Other waterfowl present included a couple hundred Common Mergansers, at least 24 Red-breasted Mergansers, Canvasbacks, a few Ruddy Ducks, Common Goldeneye, Redheads, and Greater Scaup. There were at least 20 Great Black-backed Gulls — a species not recorded in Dearborn until 1987. Ten sort of miserable looking Great Blue Herons hugged the shoreline, as did 10 Black-crowned Night-herons. There is a small pond inside the plant next to the river that accepts warm-water discharge from one of the steel mill facilities, and a bunch of night-herons have wintered there for years.

Many thanks to Larry Urbanski for this great find.
