The weather this last week has not been good for migration and very few new birds have arrived. Birds want to come though and cannot wait for ever. I have been hoping for raptors and on Sunday afternoon we had some nice sunny weather and half an hour lying down and staring skywards on the veranda revealed 2 migrating Common Buzzards and single Peregrine and Goshawk. So there are birds if you look. Yesterday it snowed with 10cm in Maridalen and a cold, northerly wind blew so it was fair to assume that nothing would be moving. Today it was still blowing from the north but was nice and sunny and that seems to be all that was needed although a snow storm mid afternoon did stop things up. I started at Nordre Øyeren (my first visit there this year) where I had a small hope of seeing a Red Kite seen in yesterday’s snow. I didn’t (although if I had stayed longer I would..) but 5 Osprey (my first of the year) were a promising sight. I decided though to relocate to Maridalen and was in place just after 11 am. I then had one of those rare events – a concentrated passage of raptors in the Dale. Over the course of 40 minutes I had 3 Rough-legged Buzzards, 3 Common Buzzard, 3 Sparrowhaws, 2 Kestrel, 1 Goshawk, 1 Peregrine and best of all a young White-tailed Eagle. A short trip early afternoon then added a young Golden Eagle!! 8 species of raptor in Maridalen in a day 😊The weather forecast for tomorrow looks much better so I look forwards to chalking up something even better! Osprey (fiskeørn) the white underwing coverts should mean it is a male but it has quite a well marked breast band all 3 of the Rough-legged Buzzrds (fjellvåk) stopped briefly up to hover and look for food it is the same Rough-legged Buzzard in all three pictures. An adult male I believe young White-tailed Eagle (havørn). This bird came from east to west and spent over 30 minutes in the Dale young Golden Eagle (kongeørn) - this bird drifted off east male Kestrel (tårnfalk) Peregrine (vandrefalk) adult male Goshawk (hønsehauk) 2cy (female?) Goshawk being chased by Hooded Crows adult male Sparrowhawk (spurvehauk) Whooper and Mute Swan in the snow yesterday. They seemed to have called a truce in their territorial dispute Chaffinches (bokfink) in today's snowstorm

Speciation—or the emergence of a new species—is a slow and steady process that plays out over millions of years among a stranded group of creatures, isolated from the rest of their kind by geographical barriers and left to evolve on their own. Or so it was generally thought. New research published in the journal Science challenges the typical... View Article

After decades of attempts to convince governments and businesses to stop the exploitation and degradation of nature, there is so little of it left that conservation alone cannot undo the damage that has been done. Logging, intensive agriculture and overfishing have pushed one million animal and plant species to the point where they're hanging by a thread. Natural habitats are vanishing. Once carefully balanced ecosystems are now at the mercy of climate change. And ultimately, the disaster happening in the natural world affects humans too. It directly impacts the air we breathe, the water we drink, the food we grow, the places we live in, and even exacerbates social injustices. Nature protection alone is no longer enough to fix this. We must usher in the era of nature restoration: we need to bring nature back.

Mer enn en fjerdedel av Norges sivhønebestand befinner seg i Oslo og Akershus. Nye registreringer viser at kunstige dammer er viktige leveområder for arten. Til tross for bestandsnedgang i våtmarker hvor sivhøna tidligere var tallrik, holder bestanden seg stabil på grunn av ny-etableringer på andre lokaliteter.

I've already given a couple of hints and it is now time to tell more about a real highlight of the last few weeks: spending quality time with Long-eared Owls. I first detected their presence a couple of weeks ago when I found pellets and droppings under trees where I had previously seen the species a number of years ago. I have always checked these trees since but this was the first time I have noted their presence again. Finding the owls was more difficult though and it took a further three visits. When I did finally find the first bird I was struck by how small it seemed - far more so than I remember from my previous encounters. The bird was able to hide away behind branches very effectively and I am sure was present on all my previous visits but that I had just mentally been looking for something bigger (and easier to find). Nearby there was a pine tree which had an old crows nest at the top. It took a few visits before I saw some ears sticking out of the nest but this confirmed that the bird I was seeing was the male (small size) and that the female was on eggs. Here are a selection of the many photos I took plus a video. I hope they convey how cool these birds are and the enjoyment they have given me. The nest can be viewed safely from a distance without disturbing the birds (access to the area around the nest has now been restricted) and hopefully these birds will keep on giving and giving as it will be great to be able to observe the adults bringing food to the nest once the nights get shorter and warmer. I would say this is one of more successful attempts at photoshopping they have very good camouflage this Yellowhammer (gulspurv) objected to the owls presence but the owl just shrugged it off

Climate change raises a great deal of uncertainty for the future of many species, including Lepidoptera. Aside from more extreme and frequent weather events, the prospect of warming climates could bring opportunities for some species (e.g. Brown Argus), and threats for others, as suitable climate envelopes are expected to generally shift polewards1. As highly climate-sensitive […]

The Bird Gods took a while to show their pleasure with me yesterday but then left me feeling very blessed. Male Hazel Grouse (jerpe) We are now getting towards the most exciting and busy time of the (Oslo Birding) year and with lots of digital and mental impressions to process from the last couple of days birding and guiding then blogging suddenly becomes a use of time that is difficult to prioritise (hence I am writing this on Saturday morning whilst the family sleeps and I have sacrificed an early morning trip to the Dale…..in mid-April....). I was booked for guiding on Friday and with a list of desired species I decided to use Thursday to search out some of these forest dwelling species. I visited the areas that have been most productive both earlier this year and in previous years and was very surprised by how little I was able to find. I only found one single woodpecker of any species (a Great Spotted) and heard none drumming (this is very worrying and makes me wonder if something is wrong). Owls were not of the hoped for small species but in my unsuccessful search for Pygmy Owl I set off a Tawny Owl that sang in the middle of the day. I eventually tracked it down and it was so active in an area where I can’t imagine there are nest holes that I believe it to be an unmated male who has just found an area with lots of food (and there were many rodent tracks in the grass). The only desired species that showed easily was Hazel Grouse and these were in my best spot for the species. On Friday when guiding I therefore headed straight to this area. Well, long story short it took two and a half hours to find them (and during this time we saw precious little else) but when we did find them we were then treated to half an hour of unprecedented views of the species. Norwegian Hazel Grouse pictures have been unusually prominent on Facebook over the last year after a photography guide has managed to habitualise a bird to his presence and been able to offer customers fantastic views (and photo opportunities). Maybe I should try this but it is I believe a process that takes many months and of course there are many other factors that are out of your own control. I think I will therefore be content with having a number of sites where I know the species occurs and just having to try all of them until we connect… The views and photographs we got yesterday could not have been better and though it is always possible to be critical of the photos I think I am unlikely to get better EVER 😊 We had a pair although as usual the female showed very fleetingly and it was the male who made his presence known. On two occasion he sat and sang in the open in sunshine and I managed to get the camera settings more or less correct! In Maridalen both Goshawk territories are occupied and there are fresh green branches on this year's chosen nests (each pair has a couple of alternative nests) – it has been a while since both pairs bred successfully so I am interested to see how things progress this year. I also checked out a Tawny Owl nest after having heard that in some places the young have already left the nest (an abundance of rodents can lead to very early nesting in owls). The response I got suggested that the female was still on eggs so I have action to look forward to here later in the spring. It would have been great to have filmed him singing at this range. Maybe a project for next week.. the female Hazel Grouse - a far trickier subject to capture I took these pictures on my recce on Thursday and at the time was pretty happy with them 😊 The distance between the pairs I saw on Thursday and Friday was about 400m and it is possible they were the same birds but I believe were different. here the bird is singing whilst looking away from me and you really see how puffed up he is And here are some other things I have seen the last couple of days. not often one finds a dayime Tawny Owl away from a known nest here he was singing (note the puffed out throat) which I should have tried to film he was getting grief from a couple of Nutcrackers (nøttekråke) when he had had enough of the scolding he flew straight over my head This video has the sound of him singing plus all the birds scolding him including Blackbird, Nutcracker and Chaffinch Yellowhammer (gulspurv) is the Bird of The Year in Norway so it is good to put the focus on one ;-) The fields are very dry in Maridalen and the Lapwings (vipe) have not started nesting yet arty photo Will Whitey stay the summer? if you choose to wear white then don't be surprised if you get mucky after playing in the mud I was very concerned when I saw this cyclist riding over the middle of the still frozen Maridalsvannet. It appeared that the ice was still thick enough but to do this in the middle of April is madness
