Clangula

Then it happens, you spot a long-tailed duck (Clangula hyemalis; hereafter LTDU).

Fish are absent, but during the growing season various waterbirds, including Red Phalaropes (Phalaropus fulicarius), Long-tailed Ducks (Clangula hyemalis), and Steller's Eiders (Polysticta stelleri), feed on the abundance of planktonic and benthic invertebrates.

The ship SS Clangula probably picked up cargo at Bristol and was torpedoed off Hartland point, North Devon, on November 19, 1917.

Bedload transport and other physical forcing variables (e.g., erosion processes) were primarily responsible for the differences across sampling stations; however, differential predation by sea ducks (Melanitta nigra [L.] and Clangula hyemalis [L.]), especially on clams <10 mm SL, across the study area may have added to the observed differences in density.

The three most common remaining freshwater duck species in Europe are two dabbling ducks teal and wigeon, in addition to one diving duck common goldeneye Bucephala clangula (hereafter goldeneye).

With any luck, the bellowing is soon replaced by the whistling wings of surf scoters (Melanitta perspicilatta), the relentless whe-oo-hoo of black scoters (Melanitta nigra), and boisterous ow-owooolee of long-tailed ducks (Clangula hyemalis) buzzing the decoys in the early morning light.

Dive durations of scaly- sided mergansers (23.6 s) were similar to values reported for Harlequin ducks Histrionicus histrionicus (22.7 s, Goudie, 1999), Barrow's goldeneye Bucephala islandica (17.5-24.3 s, Bourget et al., 2007), and common goldeneye Bucephala clangula (19.7-23.9 s, Bourget et al.,
