Note: On April 18th about 13,00 hours we were on a birding trip near Csunovo
under the leadership of Ján Dobsovic.
We had sunny weather and excellent light, and ducks, gulls, grebes a.o.
were quite busy swimming and flying, when Ján asked me for my opinion
concerning two terns standing on a piece of wood floating diagonal in
our direction in about 60 m distance. By my simple binoculars ( 10 x 42)
they seemed to be "whiter" than others, most of them flying and hunting.
Through Ján´s telescope it was obvious that those terns were not
Commons, and when noticing very short legs, tailpins proceeding the
wings, a shorter bill, a narrower cap between the ears, there was no
other conclusion left for both of us: Arctic Tern. The only
characteristic not fitting the picture was the rather reddish-black
bill, according to the drawings in "Svensson" possibly right in a phase
of change.
I may add that though I have never seen the bird near Neusiedler See/
Seewinkel I know it quite well from a one-month stay as bird - warden on
Norderoog /North-Sea ( 2001), at that time (April/May) the
breeding-birds with bright red bills of course, mixed up with Common
Terns in one colony.
