I went looking for the Bewick’s today. The location was
along the valley of the Glomma River which is Norway’s longest and drains the
mountains of central Norway, forms a delta at Nordre Øyeren and then enters the
sea at Øra. It is therefore very important for birds and seems to be an
important migration route for waterfowl. I have never been to this area before
and on first glance it didn't look to be that special with quite undulating
farmland. I stopped the car where I thought the flock would be but saw no
swans. Then a group of Whoopers flew over, coming from the river and landed
behind some trees. I was able drive up a track and there in a stubble field on
the edge of woodland were nearly 300 Whooper Swans. Going through them (at some
range) I picked up first one and them two adult Bewick's. A long awaited
Norwegian tick although a bird I saw plenty of back in the UK. At range and
when feeding in stubble the size difference to Whooper was surprisingly
difficult to see on an initial scan of the flock. Also here a single Crane (my
first of the year) but no geese.
Looking through the pictures I took it appears there could have been 3 Bewick's
(as reported yesterday morning). Check the photo yourself where birds 2 & 3
are the ones I saw in the field and 1 is the (possible) bird I only noticed in
the pictures. Basically the pictures are not good enough to be certain and after
posting the picture I received feedback from Sindre regarding the length of
bird 1’s neck such that I think it is safest to only report the 2 birds I noted
in real life. The angle of the bird can make it look smaller than it actually
is and also make the bill look deceptively small with little yellow
(alternatively it could be a Bewick’s Swan but it would also be strange that I
didn’t notice it at the time).

Is #1 a Bewick's or just a Whooper sitting at a funny angle to the camera? |

Here the smaller size of the Bewick's vs. Whooper is clear although
in the field was not that obvious during a quick scan of the flock |
As I drove on I glimpsed some geese on the river but was not
able to see properly through the trees. I drove a long detour to come closer
and at Utnes Church I had a great view over the river and there on some distant
mudfalts was a large flock of Bean Geese loafing around. I counted 172 birds
which is a very large number for southern Norway. Those who saw them closer
yesterday saw that they were Taiga but the distance was too great for me to
assign them to race. Also some of the birds had neck collars but it has also
not been possible to read these. I have always wondered as to the origin of
this flock that migrates through Akershus each year and have wondered if they
could be one of the two flocks that winter regularly in the UK. If someone is
able to read the neck rings then maybe we will get the answer.

After this I visited the area near Gardemoen Airport where
Woodlarks breed but it is probably still to early and the cold westerly wind
definitely didn’t help either. A quick drive around Maridalen revealed a pair
of Whooper Swans which is not surprising given the large numbers elsewhere and
it will interesting to see if this is the breeding pair.
