The sightings and occasional thoughts of an English birder in Oslo

Back to Svellet
The Beast turns 8 in September which coincidentally means
that according to all that dog/human year malarkey he and I are the same age
(at least for now). I guess there have been a few thousand morning walks he has
taken me on over the years and we have seen a few interesting birds in the area
where we live with Pine Grosbeak probably being the best. Yesterday morning
though we added a new species with a Wood Warbler singing in the local wood.
Although the oak dominated wood may be suitable as a breeding locality I am
sure the bird was a migrant. As such I think it is only the second time I have
come across a singing spring migrant (not that I have come across any non
singing ones either). And that got me thinking - why do I hear many singing
migrant Chiffchaffs and Willow Warblers but not Wood Warblers? Is it because
Wood Warblers don’t often sing on migration or is it just because there are so
many, many more Chiffs and Willies that you are so much more likely to
encounter one of them?
Svellet was the subject of my attention yestday and whilst
water levels have only risen by 2cm since yesterday and 4cm since Monday there
was a considerable reduction in the number of birds. And I was able to watch
that number more than half when a young Peregrine had a go at some Wood
Sandpipers which of course all flew off but also never returned.
Over the past couple of weeks I have seen the waders
frequently flying around due to a raptor (most often unseen) but always landing
again but what I observed today clearly shows that migration awaits and the
birds clearly have an unavoidable urge to keep heading north.
We have a couple of days of rain ahead of us and also
southerly winds after aperiod of cold northerly winds so we may still have some
mighty experiences at Svellet but it will definitely be a question of quality
rather than quantity now.
I also walked out to the end of Årnestangen which was a
rather quiet affair on the bird front with not a single waders at the tip but
there were two butterfly surprises with my first Swallowtail and Painted Lady
of the year which were not what I expected on a quite cloudy and not that warm
day.

In Maridalen the Lapwings continue to surprise positively with 3 broods seen - 4 and 1 were on open ground and fully accounted for but another single youngster popped out of long grass and there could definitely, and hopefully, have been more there. Two females are also on new nests and a pair were displaying so there may be yet another nest to come. They all still have to survive more farmer activity and foxes and crows but I think we are in a surprisingly good place.
my first Painted Lady (tistelsommerfugl) of the year. A faded but otherwise undamaged individual
whereas the colours of my first Swallowtail were perfect it had clearly already been attacked by birds and had chunks missing from the back of its wings
