Dear All

As some of you might recall, a 1cy Baikal Teal was shot by a Danish hunter
in November 2005.

The hunter was quite puzzled about the bird in question and reported to
the National Environmental Research Institute (NERI) that he had shot a
teal with wings like a Pintail. The hunter agreed in sending the teal to
NERI and the staff at NERI quickly identified the bird as a 1cy Baikal
Teal.
The bird was in good condition and had started to moult the juvenile
feathers.

NERI decided to investigate the origin of the bird further and an isotype
analysis based on the feathers was carried out (deuterium and oxygen). The
feathers were sent to Scotland for analysis.

The conclusion is clear according to NERI. The bird has its origin
somewhere in Siberia. The juvenile feathers showed values which only was
comparable with values from areas, where Baikal Teal breeds. The moulted
feathers showed values, which was comparable with values from Mallards in
Western Europe. On the basis of the difference in values between the
juvenile feathers and the newly moulted feathers, it could be concluded,
that the Baikal Teal in question is a genuine vagrant.

If accepted by the Danish Rarity Committee it will constitute the first
record for Denmark and probably the first proven genuine record for
Europe?

So far it seems that only The Netherlands, Belgium and Italy treat Baikal
Teals as genuine vagrants. But with the Danish record in mind, unringed
individuals might gain extra interest in the future.

According to Thomas Kjaer Christensen at NERI, a more scientific article
about the method has been prepared and sent to Ibis.

For further information about the record contact Thomas Kjaer Christensen
at NERI or read more at www.Netfugl.dk - though only available in Danish.

De Deense vogel is dus een wilde vogel! Dat is neem ik aan toch heel goed nieuws voor de vogel van de omgeving Amsterdam van afgelopen mei.
