On the 30th of August 2005 we caught among some Barn swallows
a hybrid between a Barn swallow and a House martin in our
garden in Mecklenburg-Vorpommern (Germany). After ringing we set this
bird free again.
While having this hybrid in our hands we noticed few feathers on its
feet, no white spots on the tail feathers, the whitish rump and the
washed breast band. Also the morphometric parmeters we took differed
from "pure" Barn swallow.

The mass of this hybrid was 23,1 g, the 3rd primary was 91,5 mm and
the wing length was 120,5 mm. It was a first year bird and we ringed
the ring HIDDENSEE ZC35153. Only four other hybrids of this type
were marked before with rings of the ringing center Hiddensee,
although there is a lot of
Barn swallow ringing through the EURING Barn swallow program.
Unfortunately we don't know where the caught hybrid hatched.
It could come from a place far away like a retrap we made the day
after the trap of the hybrid (31.08.05) showed. There we caught a first year
Barn swallow with a ring of the RIKSMUSEUM STOCKHOLM in our
garden. This swallow was ringed as nestling on 07.07.05 near Malmö
and had to fly across the Baltic Sea.
Many thanks for the very soon answer of the
ringing center Stockholm. We got the detailed ringing datas within hours :-)
