Back-throated Diver (storlom) |
Today started without a hint of wind in the air. It was
overcast and cold and with a threat of rain but the lack of wind made it
pleasant – it also felt like there would be birds to be seen.
I had decided that I would go to Svellet again today as the
weather would make for much better viewing conditions than I had yesterday
(when there is sun the heat haze makes it very difficult scanning the vast
mudflats). Something told me to visit Maridalen first though....
There were no new (or old) ducks on the water at Hammeren
(the lake is still 95% frozen) but the pair of Black-throated Divers were
there. So, no influx of diving ducks but perhaps not surprising with so little
open water. I stopped at the church ruins to check the fields and also the bay
here. On the ice were a lot of gulls but I could find nothing unusual (this
time last year the Med Gull turned up on the ice). The fields of burnt stubble
still held a lot of birds though with at least 7 Ring Ouzels (ringtrost) which
are unusual here in May, 2 Twite (bergirisk) with the male having a
particularly pink rump and a resting Golden Plover (heilo) amongst the commoner
birds. As I walked along the path a lark flew up and circled over me. It didn’t
call and against the sky I couldn’t noticed any plumage characters but it felt
good. It landed behind a ridge in the field and I was able to approach closer.
It then popped its black and yellow head up to confirm a Shore Lark (fjellerke)!
The sight that greeted me |
Although this bird has its European breeding stronghold in Norway it is a great
rarity in and around Oslo so this was a patch and county tick for me. It stayed
loyal to the same small field and was seen by several others during the day.
Shore Lark (fjellerke) - a new species for me in Maridalen |
In the beginning of May I would expect a field like this to
be holding real heralds of spring such as Yellow Wagtails (gulerle) and
Whinchats (buskskvett). It is a real sign of the late spring therefore that it
is birds such as Ring Ouzel, Twite, Golden Plover and Shore Lark that are here –
one could almost believe one was in the mountains in July!
Feeling torn as to whether to continue searching in
Maridalen or go to Svellet I decided on the later although had to stop the car
twice on the way out of Maridalen as two flocks of Pink-footed Geese
(kortnebbgås) headed north. By the time I got to Svellet a southerly wind had started
to pick up and with a lack of suitable clothes I started to feel bitterly cold and
this could be the cause of my subsequent delusions.....
Wader numbers had noticeably increased from yesterday and
there were now at least 60 Greenshank (gluttsnipe) plus 4 Wood Sandpipers (grønnstilk).
Also on the mud a male Yellow Wagtail of the Scandinavian race thunbergi and my first Sand Martin (sandsvale) of the year was hunting for (non exsistent) insects.
Whilst going through the waders hoping to pick out something
rarer I found a smaller, pale wader with a distant group of Greenshanks wading in
the water.
Doesn't that look like an exciting wader? |
I really wasn’t sure what it was and made my way laboriously towards
it through the oozing mud. It looked very exciting and my thoughts started
drifting towards its being a Stilt Sandpiper (sytlesnipe). It appeared long
billed and long necked with a prominent supercilium and the way it was wading
with the Greenshank started getting me convinced this is what it was. Still I
wasn’t quite sure which luckily stopped me from sending out any foolish messages!
strong supercilium, long (?) black bill |
can that really "only" be a Knot (polarsnipe)? |
I saw it in flight and the wing bar and grey rump didn’t add
up but I still didn't know what I was looking at.
the flight shot reveals no doubt - there is no other species than Knot with the obvious wing bar and pale grey rump |
It then landed beside the Wood
Sandpipers and was noticeably bigger. This wasn’t right for Stilt Sand but what was it then?
Per Buertange then called me and I was able to get him to go through a bird
book quoting measurements to me. It was only then that things started to fall
into place and the wing and rump/tail pattern made sense. It was a Knot! But
why wasn’t it red, what was it doing with Greenshank and wasn’t that bill too
long?
It must be a 2cy bird moulting into 1st summer
plumage which explains the lack of red in the plumage and the otherwise pale
faded feathers but I still cannot quite get the bill and neck to fit with Knot
but that flight shot doesn’t leave any doubt. Also I understand that the most birds in their first year usually stay in winter quarters and do not migrate north. Just one of those birds I guess.
Tonight and tomorrow there is forecast continued strong southerly
winds and rain which should cause a good fall of waders plus others. Where to
go?
