After my first sighting of Pine Grosbeak on Wednesday, I found none yesterday but today had ten in total including my first adult males and my first in Maridalen. It is not quite invasion tendencies yet but I reckon we will have a good, if gradual, arrival. The birds I saw today were in spruce but they will turn up in an urban car park soon.
Maridalsvannet was completely calm today and revealed a total of 12 Common Scoters and the juv Black-throated Diver which is still present and may well not leave until the lake freezes which the way things are going may not be until well into 2027.
It is so mild that dragons are still flying and I also had a butterfly today which flew too quickly but was probably a Comma (hvit C).

Common Scoter (svartand) and a Wigeon also on Maridalsvannet today
Crested Tit (toppmeis) are quite easy to find at the moment
2 Pine Grosbeaks (konglebit)
and another two which were part of a flock of eight that were all in this tree top and included two adult males but it was only when they flew that I realsied how many there were
the Grozzas were at Grefsenkollen which has a great view over the city and fjord
these two ferries (one coming from Denmark and the other Germany I believe) offer mini cruises and always seem to race each other into Oslo in the morning

Ever since my first autumn trip to Værøy in 2012 the sound of and then sight of Yellow-browed Warbler has been an essential and longed for part of my birding year.
Even the years when I wasn’t able to visit Værøy I have managed to see and hear the species until last year when I drew a blank. I assumed that my planned visit to Værøy in a weeks time would remedy that this year but yesterday I had a far, far, better blank buster.
I have had the “tsuit” call of YbW on my mind for the last two weeks and have had my ears peeled in the never ending hope of actually hearing one. Finally I was no longer hearing it inside my head - the sound was real and coming in through my ears. AND I was in Maridalen where the species has never been recorded before AND there was not one but two birds calling AND there was even some (sub)song AND I saw at least one of them well AND I got photos.
Værøy will have to produce something a Cosmic Mind F*cker (as the late, great Bill Oddie termed it) to beat a YbW IN THE DALE!!!
This was my third YwB in Oslo but was a new species for Maridalen taking the Maridalen list to 229 species of which I have now seen 214.
This video has the call, of one and then two birds and the subsong can also be heard
photographing it with the superzoom high up in the trees was nearly a challenge beyond my abilities but eventually some record, and even slightly artistic shots were bagged

do you spot it?

The second half of the week has, unsurprisingly, not been able to measure up to the good start but it has offered some good autumn birding. A trip to Nordre Øyeren today in damp conditions revealed a Svellet completely free of waders despite there being lots of attractive (at least to me) mud still showing. There were three Great White Egrets close by though and this is now a characteristic species for the area in the autumns. Despite it now being expected it is still a bit of kick to set your eyes on them and they are still exotic.
Bird of today was a calling Red-throated Pipit (lappiplerke) that flew right over my head when I was looking over Snekkervika but it wouldn't stop unfortunately. Also still there were two Red-backed Shrikes (tornskate) which are getting to be quite late.

A Nutcracker (nøttekråke) collecting hazel nuts in the garden on Wednesday. They do not eat them but rather fill up their throats/crops and fly many kilometers into the forest with them where they hide them to be eaten during the winter. In the video you can see it taking nuts and also see the bulges in its throat
This mink in Maridalen did not seem to have seen me and The Beast sitting only meters away but as can be seen could definitely smell us
I felt a need to post, no matter how briefly, a few days ago as a very close friend of min recently took his own life and it has been a very strange and emotional time and a reminder to me of the need to communicate. Birding has been, as it always is, a good way for me to keep myself in balance and I have not been spending time in front of the computer or editing photos.
I have this evening found a few more photos and videos from the last week in Maridalen which show a bit how things are there. Autumn migration is starting and the hope is always for something very exciting to turn up although currently I am more aware of the breeding birds disappearing.

In this video of Red-throated Divers (smålom) which have not bred on Maridalsvannet but have now moved here from their nearby breeding ponds you can see a juvenile that is begging for food by stroking its parents throat with its bill
a visit to Svellet with Jr Jr to give her some driving practice (her driving test is coming up) looked like it would be very promising but there was no birding gold at the end of the rainbow
a caterpillar of a Pine Hawk-moth (furusvermer) Sphinx pinastri
and the caterpillar of Elephant Hawk-moth (stor snabelsvermer) Deilephila elpenor shown in the video in my last post. I found both of these wandering on roads and they are searching for places to turn into a pupa
Just in case anyone was worried and wondering if I am still here then yes I am 😊
This very short post doesn’t feature a single butterfly, although there is a caterpillar of an Elephant Hawk Moth (stor snabelsvermer) which is a quite fascinating creature.
This video of things that I came across the last couple of days also shows you what I have basically been spending all my available time watching and documenting since coming back to Oslo at the end of July.
Some pleasant surprises in Oslo and Maridalen regarding
breeding birds means I am not completely over into the butterfly world just yet.
On the lake there was suddenly a single adult Mute Swan with
5 small young! This is just like last year in that they suddenly appeared but
this year I was better prepared and had discovered the nest on 26 May. After
that discovery of the nest though I had been unable on subsequent attempts to
see any birds on it (although it was very difficult to see) and had only a
record of single adult on 1 June and then a pair flying over the lake (not near
the nest) on 9 June. I therefore assumed that the nesting attempt had failed
and the birds had moved off. To suddenly see an adult with young was therefore
a shock and it was equally surprising that I could not find the other adult
anywhere on the lake. Has the male died or moved off? And if so how did the
female managed to incubate and feed without me ever seeing her? And the pair I
saw on x June – were they visitors? Perhaps the other pair that started nesting
and then gave up? An answer to the first question is that P578 who I saw on
Maridalsvannet on 29 April, and his ring was again read on 24 May, who is the
male of the pair that bred last year and I assume the father of this years young
was seen on 16 June at Fornebu where he and his mate had spent the winter – so
it looks like he has left his mate to fend for herself! Did this happen before
the eggs hatched?
Mute Swan (knoppsvane) - presumably female PC79 who bred here last year - with 5 small young but not with her mate (P578) who has flown down to Fornebu!
The Black-throated Diver pair (one of perhaps two on the
lake) still have a single youngster and have moved quite a way from the nest
with it.

The ever growing cereal crop on the Lapwing field makes seeing
the birds very difficult but yesterday I could see 3 (2 + 1) almost fully grown
young which is a great relief but the fate of the two last nests remains unknown.

And finally, I had Red-backed Shrike in the Dale this year
and it seems to be a nesting pair so fingers crossed for their success.

A visit to Østensjøvannet today also revealed lots of young
birds. Best of all were the Black-headed Gulls which have had their first successful
breeding season (at least as a colony) for a few years with many large young on
two islands. Great Crested Grebes, Coot and Mute Swans also had young (the
later no larger than the ones I saw on Maridalsvannet) and surprisingly a
female Goldeneye had 11 quite large young with her. This raises two questions –
are they all hers? Perhaps unlikely. And how have so many survived so long? Normally
the vast majority get eaten either by gulls or pike.

and a male Gadwall (snadderand) which once again seems to have chosen Østensjøvannet to moult although this year there were no records earlier in the spring
