I have
checked the fields in Maridalen at different times of the day both yesterday
and today but despite the small Common Gull flock still being there (it builds
up during the day) I have not seen the Med Gull again unfortunately. The
Whooper Swan youngsters can clearly now fly as on Sunday they were feeding on a
field a good distance away from the breeding site. Unusually they were only
with one parent and I feared that something had happened to the other. I found
the other back at the breeding site where it had no obvious injuries, but it
allowed quite close approach and then swam off calling but did not flap its
wings at all. I wonder if it is injured on some way such that it can’t fly or
perhaps it is waiting/searching for the youngster that disappeared quite
recently? Time will tell as it will have to join the rest of the family soon
especially if snow and ice comes. If it is injured then this clearly points to
something rather sinister having happened to the swans this year. They have
gone from 7 iyg to 4 large young and then lost one just before fledging whereas
in previous years have raised large broods with hardly any birds lost after
hatching. It could of course be natural predation (there is a recent report of
wolf in the area plis of course fox and mink) but it could also be from dogs or
humans. I have not seen any carcases or piles of feathers in the area to help me
work out this puzzle.
I did see
an interesting gull today though. It is autumn half term and the girls, and I
enjoyed a sunny but slightly chilly walk around Fornebu (we had an overnight
frost). Here a 1st winter Kittiwake showed at very close range and perched.
It flew strongly enough but when perched didn’t look that strong so is probably
not fully fit which would also explain why a normally pelagic species is
hanging around urban areas.

1st winter Kittiwake (krykkje) |
|
in flight is can be confused with Little Gull (dvergmÄke) but has different proportions and white secondaries |
|
this young Lesser Black-backed Gull (sildemÄke) should have migrated by now but was not looking fighting fit either |
