VAN DIEK H, GELDERBLOM PG (2020) First nest find of Long-tailed Duck Clangula hyemalis in the Netherlands. LIMOSA 93 (4): 180-184.
After the sighting of a first successful breeding attempt of
Long-tailed Duck in the Netherlands in 2019, with four young
on the artificial islands Marker Wadden in lake Markermeer,
a Long-tailed Duck nest was found for the first time in
the Netherlands in 2020 near the town of Lienden, in the
province of Gelderland. A female Long-tailed Duck and a
pair of Long-tailed Ducks was already spotted near Lienden
in respectively spring 2018 and 2019. In 2020 the behaviour of
the pair indicated a breeding attempt, which initiated a nest
search. On the 13th of July a nest with seven eggs was found.
Unfortunately, four days later the nest was predated by an
Two breeding attempts in the Netherlands within two years
is remarkable, since the breeding and wintering population
of Long-tailed Duck in Europe shows a large-scale decline.
None of the birds showed indications of a captive origin (wild
behaviour, no rings, no damaged feathers). The breeding
attempt of Long-tailed Ducks far outside its breeding range
does not entirely stand alone, as a few pairs of Smews
Mergellus albellus have been successfully breeding in the
north of the Netherlands for almost ten years, also with no
indications of a captive origin.
