Water Pipits (vannpiplerke) are very interesting birds in
that they are the only European bird I can think of that migrates north in
winter. They breed in the mountains of central Europe and winter by wetlands
and sometimes coasts in lowland Europe (both north and south of the breeding
grounds). They are also a very tricky species to identify and were until fairly
recently treated as a subspecies of Rock Pipit (skjærpiplerke), indeed in the
authoratitive Birds of the Western Palearctic (BWP) from 1988 it says, under
Field Characters: “Rock and Water Pipit groups separable in adult breeding
plumage but often not so at other times”. Water Pipit is a rarity in Norway
with no more than a couple of records annually normally of birds associating
with Rock Pipits on sandy beaches where they can find insects amongst piles of
rotting seaweed. I have never seen Water Pipit in Norway and I must admit to being
slightly sceptical to some records as I believe that the variability in litoralis Rock Pipit is greater than is
generally accepted. The Rock Pipit I saw 7 November is a good example of a very
pale Rock Pipit showing many characters of Water. Today was therefore a good
opportunity for me to see Water Pipit side-by-side with litoralis Rock Pipit.
Two Water Pipits were reported on Sunday from Nevlungstranda,
Mølen in Vestfold which at nearly two hours drive from home is right at the
edge of my self-imposed limit for regular birding trips. Today I only managed
to find a single bird with certainty amongst 12 Rock Pipits (20 were recorded
on Saturday). When I first arrived around 0930 the sun had yet to rise over the
horizon although the light was good. This meant that I could watch the pipits
in a neutral light. I found the pipits quite easily feeding amongst the
boulders and seaweed and the third bird I saw was clearly a Water Pipit. It’s
underparts were very white and it stood out like a sore thumb.

After the sun rose it became a bit more difficult. The birds
became wary plus the warm, low winter light made judging colours challenging. A
Rock Pipit bird with the sun on it could suddenly appear to have very white
underparts whereas the upperparts could have a warm brown tinge which is
supposed to be one of the features of water pipit. However, with good views the
Water Pipit could be picked out.

This pose is similar to the bird above in neutral light but note how the upperpart colours look much warmer in the sunlight |
One of the Rock Pipits bore a yellow colouring ring EEL. This
bird has been recorded at Mølen previously with the first record on 2.11.2011. The
bird was ringed at Giske, Møre & Romsdal, Norway on 02.10.2011 and was seen
at Mølen already on 02.11.2011. It spent the rest of the winter there and was
back again for the winter on 30.10.2012. Colour ringed birds from the same
location have also been seen in Sussex, England (my old stomping ground).

Rock Pipit (skjærpiplerke). The yellow brown ground colour to the underparts leaves no doubt this is a Rock Pipit but the upperparts had a very warm brown hew in the low winter sunlight. |
On the sea a single Long-tailed Duck (havelle) and two Shags
(toppskarv) amongst commoner seabirds were good finds.
I had a walk around nearby Mølen where there were 100 Velvet
Scoters (sjøorre) and a Red-necked Grebe (gråstrupedykker) were the highlights.
Driving towards Tønsberg I took the scenic route hoping to
score some Hawkie as I needed a hit. And sure enough.......
A Hawk Owl has been seen in this area in since 8th December but
was last reported 22nd December.
In Tønsberg I visited Presterødkilen. Here the bay was
entirely covered in ice despite it being barely zero degrees and the last few
days not having been particularly cold. The reeds still held Water Rail
(vannrikse) and Bearded Tits (skjeggmeis) although I only heard them calling. I
had to go out to the open sea to find some ice free water although fog made
visibility quite limited. At Jarlsø two Little Grebes (dvergdykker) were nice
to get onto the year list.
