Goosander Duck:
UK Status: Resident,
first bred in the UK in1871. There are four to five thousand breeding
pairs in the UK, these numbers swell to more than fourteen thousand
during winter when the overwintering birds arrive.
Habitat: These vary
gregarious birds are to be seen in upland rivers during the summer,
mainly in Wales an Scotland. During autumn through to late spring they
move into lakes, pools, rivers and sometimes sheltered river estuaries
at lower altitudes. Often they are seen in large flocks.
Breeding: Goosanders nest
either alone, or in small groups, depending on on the number of
available nesting sites. Nests are placed in cavities between rocks or
tree roots, hollow tree trunks are highly favoured. These cavities are
usually just lined with masses of downy feathers. There are eight to
twelve pale yellowish colour eggs in a clutch, which are only incubated
by the females. When the chicks hatch they rapidly take to the water,
it's at this point that the males migrate to lower altitude. Females
finish raising their young alone, and then migrate to lower altitude.
Comment: Not uncommon,
though rarely seen on lowland waters during the summer. Non resident in
Ireland, though they do see overwintering birds. In the rest of the UK
these birds are mainly found in Wales, Devon and Cornwall, Northern
England and Scotland.
