Most, but definitely not all, winters see the arrival of a scarce irruptive species (or two or three) in the Oslo area. The classic species are Pine Grosbeak, Two-barred Crossbill, Hawk Owl and new to the list Great Grey Owl. We currently have a good berry crop especially on planted asal trees in urban areas such that we can hope that if Grozzas do irrupt this autumn then we at least have food for them. berry laded trees on this morning's dog walk. I can never remember quite so many berries on these exact trees We had none last winter but proper invasion winters in 2024/5, 2021/2022, 2019/2020, small numbers 2017/2018 and 2016/2017 and good numbers in 2012/2013 when there were no berries but they fed on fresh shoots in spruce trees. Two-barred Crossbill is far less regular but we had good numbers in the winter of 2019/2020 which was a good crossbill winter in general due to a lots of cones but should they also arrive when there are not cones then they may find other food such as in the winters of 2014/15 and 2013/2014 when small flocks fed on some ornamental seed stones in the Oslo Botanical Gardens. Owls irrupt following good breeding seasons which means there are a lot of owls and then a collapse in rodent populations means little food and causes the owls to spread out looking for places where there is food. Hawk Owl has long been a species that can turn up around Oslo and does so pretty much every 4 years with a bird last winter in Maridalen and multiple birds in the winters of 2024/25, 2020/21 and also 2019/20, 2016/2017 and 2012/13. It is therefore not to be expected that we have a bird this winter but of course not impossible. Great Grey Owl is so new as a breeding species in southern Scandinavia that we have no history with which to make predictions and it is only the winter of 2019/20 that we have previously had the pleasure of their company in Oslo. However, it is clear that they irrupt in the same way as Hawk Owl with good breeding seasons followed by rodent population crashes causing them to wander. Great Grey Owls had a very good breeding season in their core area last year which I was able to enjoy but less successful this year as rodent numbers had already started to decline. Rodent should now be hitting the bottom of their 3 to 4 year cycle meaning there are good numbers of owls needing to find food. There have already been reports from the coast suggesting birds are on the move so my hope has, for quite a while, been that this winter will again host GGO in Oslo. We also have lots of new clearings due to extensive forestry work and these provide ample (perhaps too ample for the birder wishing to find one) hunting grounds for the owls. The only remaining blocks that have to fall in place are for there to be enough rodents around Oslo to sustain an owl or two during the winter and for the owls to find them and decide to stay. There have been no signs that this summer has been good for rodents with Tawny Owls being unusually hard to hear in Maridalen but intriguingly there have been a small handful of reports of Great Grey Owl from the Maridalen and Lillomarka area since last November. Some of these were third or fourth hand reports that were difficult to know what to make of but there have been some photographed birds. I am certain that there has not been breeding but rather wandering young bird(s) from last summer’s good breeding season further north have made it to the Oslo area and are scratching a living. A report of a bird on Sunday with photographs clearly taken with a mobile phone of a bird hunting in the day in Lillomarka was interesting and exciting. Was it the same bird that had been reported those handful of times or was is a new wandering bird and the vanguard of the invasion I have hoped for? We can of course not know for sure but developments through the late autumn will give us a clue. I of course went looking for it yesterday morning and for once took the Beast with me as a long and potentially unrewarding walk in the woods would be made more enjoyable with some company and as he now approaches late middle age he has become a bit easier to take birding. Also, he would hopefully be a lucky charm as his breed name Finnish Lapphund shares the same Lapp name as Great Grey Owl in Norwegian (lappugle). A bit convoluted I know but I will take all the help I can get. We didn’t find it in our first check of the area where it had been seen the day before and continued through the forest checking out where Honey Buzzards had bred this year in a new nest but which I had not previously visited due to my far more accessible nest in Maridalen. Coming back a couple of hours later though there it was perched very openly on a tree stump just as they are supposed to do. There then followed nearly three hours of observation when I watched it make four succesful catches all of which it ate on the ground so I could not see exactly what it caught but once did see a long tail sticking out as it swallowed the prey. After the first three catches it resumed hunting immediately and it was only after the fourth that it seemed sated enough to relax and preen. It had clearly found an area with, for the moment at least, good numbers although the fact it is hunting so much during the day in such an open area does suggest that the bird is both very hungry and that there are not many rodents as otherwise it would hunt within the forest as night. It will be interesting to see how long it stays but I doubt the one small area where it was can have enough food to sustain it for too long so it will surely soon move on although maybe not far. I continued my long track record of failing to press record when I thought I had so do not have digital memories of some of the scenes I witnessed but have managed to capture some hunt and flight sequences. Great Grey Owl (lappugle) much too low shutter speed but I don't think anyone would expect anything else of me :-) well camouflaged in black and white it very clearly has two generations of primary and secondary feathers which I interpret as meaning it is a bird born last year with a mix of juvenile and adult feathers some pics from the phone including an obligatory selfie lapphund og lappugle

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. Great White Egrets (egretthegre) - the bird on the right is perhaps an adult with what look like plume feathers sticking out This video shows a dark juvenile Honey Buzzard and an adult Common Buzzard in Maridalen on Wednesday and continue the great run of sightings I have had this autumn a video grab of the dark juv HB and a picture of the pale juv HB that isn't in the video the dark juv HB with a moulting (adult or at least 2cy+) CB In this video of a Black-throated Diver family on Maridalsvannet from Thursday the youngster can be seen being fed small fish juvenile Black-throated Diver (storlom) BtD family Goosanders (laksand) a record breaking flock of 32 Cormorants (storskarv) that flew into Maridalsvannet yesterday and immediately set about feeding (or at least searching for fish) as a flock as can be seen in the video Shoveler (skjeand) including an adult male in eclipse which I don't remember having seen in Norway before and a pair of Gadwall (snadderand) at Merkja today 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
