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. Black-throated Diver (storlom) family 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. a nearly fully grown Lapwing (vipe) young 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. pair of Red-backed Shrikes (tornskate) in Maridalen and the male on his own 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. Black-headed Gulls (hettemåke) have had a successful breeding season at Østensjøvannet 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

Last autumn I wrote a post summarising a great year of buttering and I also listed the remaining Norwegian species I had yet to see and how I could go about that. Yesterday was time to start chipping away at that list and a trip to Hedmark was in order to search for Lapland Ringlet (emblas ringvinge) and Bog Fritillary (ringperlemorvinge). I chose yesterday as it was forecast to be warm but cloudy with periods of sun. I thought this would be better than a very sunny day as the butterflies were more likely to rest when the sun went behind a cloud and allow me to get photos rather than them just flying around manically. I had an early start from Oslo and arrived at my chosen bog by 0930. I then began to doubt my strategy as there was rather a lot of cloud in the sky and no immediate sign that the sun would shine. It was warm though and moths were flying around. I thought that I might scare some butterflies up if I walked around and succeeded in seeing a Northern Grizzled Skipper (moltesmyger) which was only me second sighting ever. A couple of fritillaries also flew past quite slowly but frustratingly did not land within sight of me. I needed sun and eventually I could see that there would soon be a large gap in the clouds - and that did the trick. Suddenly there were quite a few fritillaries on the wing. The first ones that I managed to identify were Pearl-bordered (rødflekket perlemorvinge) but most just zipped by. I did have my butterfly net with me although I am normally equally as (un)successful with it as I am at scratching on tree trunks and managed to net one. And, it was the first of my targets - a Bog. Things then became easier and I saw a number of them and got photos and it was probably the commonest butterfly there. I also had some more skippers and then a giant of a butterfly - a Baltic Grayling (juttas ringvinge). Again this was only my second ever sighting and in total had probably 4 individuals which frequently landed on tree trunks. I was still missing my second target species but after 2 hours I saw another dark butterfly but it was smaller than the graylings and it kindly landed and allowed photos. Embla in the box - the day was working out entirely to plan 🦋🥳. I had good time to continue further east and check out some flower rich road verges where I have stopped a couple of times before including in July last year for Silvery Argus (kileblåvinge). I was a bit shocked to see that the verges had been scraped to dig drainage ditched but did find some untouched areas and here found a couple of Chequered Skippers (gulflekksmyger) which again and for the third time was only my second ever sighting and they were mint individuals. A few Violet Coppers (fiolett gullvinge) were past their best but were probably the rarest butterfly of the day although it is a species I have been lucky enough to see a few times before. Yesterday takes me to 84 species of butterfly in Norway and leaves me just 17 to get. And birds? Well, there were some but nothing to write home, or on this blog, about. the first target to fall - Bog Fritillary (ringperlemorvinge). The line of white circles at end back of the underwing are diagnostic from above it looks like a Small Pearl-bordered (brunflekket) but note how the black spots bleed into the triangular markings and this appears to be diagnostic this one got me very excited and I was thinking a Friggs Fritillary but turned out to be an abberation of Bog. Unfortunately I did not get any pictures of the upperwing but we can see some of it and it is mostly dark and on the underwing it is much darker than normal and target #2 - Lapland Ringlet (emblas ringvinge). I only has this one individual with a bit missing from its wing and my second ever sighting of Northern Grizzled Skipper (moltesmyger) and much better than my first and my second ever sighting(s) of Baltic Grayling (juttas ringvinge) - a large butterfly that has a 2 year syklus waiting for the clouds to move the forest bog when the sun was shining - this type of habitat must be very common but rarely visited by anyone with an interest/knowledge of butterflies so many of the species may be far more widespread than the handfull of annual records suggest and my second ever Chequered Skipper (gulflekksmyger) which was a much more satsifying sighting than my first last year which was so late and faded that it was barely recognisable and the rare Violet Copper (fiolett gullvinge) a tiny orchid growing on a roadside verge - Early/Northern Coralroot (korallrot)

Only ten years ago it looked like Blyth’s Reed Warbler was going to establish itself as a regular, if rare, breeding bird in south east Norway. It bred in Maridalen in 2015 and in my experience a surprisingly high number of the singing males that turned up other places around Oslo ended up finding a mate and breeding. But then the upward curve peaked and a decline started with the species becoming less regular. It is a classic nocturnal singer species and also a late arriver and is often not found until us birders go on our nocturnal trips when there is nice warm weather in mid June. This year though the species was looking like it was going to be desperately scarce with only 10 birds in Norway up until June 8th but since then there has been a solid arrival with at least a doubling of birds. One of these was found last night in urban Oslo by who else than Stig Johan (there are not many people who would go birding in the middle of the night where he goes) and was still singing strong when I visited at 11am in a rain shower. They really are one of our best singers and this bird put on quite the show at point blank range. It was along a well vegetated stream under overhead wires by a car park for busses - perfect habitat! The weather forecast for the coming week is conducive to nocturnal trips so maybe there will be more Blyth’s to find and hopefully a River Warbler or Corncrake.
