Bigger and better Hooters!


As I said in my last post I had some owl action last week 😊

A trip to Owl Rd with Jr after I had been informed of a new site to try for GG paid off big time. It was once again a “perfect” night with no clouds and no wind although this time there was no moon either. At a barmy -2C it was also warm…

On the drive down Owl Rd we heard nothing of the GG. We (or more accurately me as Jr doesn’t get out of the car to just hear owls)  did hear a single Tengmalm’s and then of much more interest a hooting male Ural Owl. Although it was at looong range it was a special bird for me as it represents a self found tick, an Akershus county tick and the first time I heard song (my previous records have either been nesting or winter birds).

The forests here are a southerly extension of the deep forests of Hedmark where Norway's ca.25 pairs of Ural Owls breed and there are a couple of previous records of singing birds on the Akershus side of the county line. It has therefore always been a species I have hoped to hear on my visits to the area so was very satisfying when it finally happened.

On the way back the desired Great Grey sang and was right by the road meaning Jr also got out of the car to enjoy him. It was in  the same area as the bird I filmed last year so could well be the same individual. There was nothing to suggest a pair but I will follow up.

 

As if that wasn’t enough, I then had the pleasure of reacquainting myself with Hawkie in Maridalen who is now hunting from low perches in open woodland which would explain why it has not been seen for a while. I was lucky enough to see it catch a mouse/vole and then eat it.

As it that wasn’t enough a bit later an alarm calling Crossbill alerted me to a Tawny Owl at is daytime roost high in a spruce. It was close to a Goldeneye nestbox and I will have to follow up to see if there are Tawnies nesting here although the hole looked a tad small.

this video sht by Jr has me taking pictures of the owl. You can hear how slow the shutter speed - I was using 1/15 second and a tripod

Hawk Owl (haukugle)





he then flew down and caught a rodent as seen in this video:



before dismembering and eating it:

here he has just landed on the other side of the road with his prey

by the time I had got a bit closer the head had been removed and swallowed


then the inners get eaten






before the rest is just swallowed





ever get the feeling you are being watched? Tawny Owl (kattugle)



A trip yesterday in very similar conditions revealed just one distant hooting Tengmalm's so it clearly isn't a great owl year any more. I have read that if the snow melts too quckly then this can cause a collapse in rodent populations that had been thriving under the snow and the snow did definitely melt quickly here  at the end of February. Even if owls don't always play ball though there can be plenty of other things to see on a cloudless night in the forest. I have seen meteors burning through the sky and last night Jr and I saw this very strange sight which was apparently a string of US Starshield satellites launched by Space X from Californian the day before (Friday) and which are moving themselves into orbit. They moved through the sky in a straightline and were a definite a UFO until we heard about them on the radio a bit later (clearly lots of people had contacted the press about them).


we also had a good show of Northern Lights

and a couple of still white Hares running along the road

The Big Pink Day

The last week saw the greatest migration day of the spring, at least as far as quantity is concerned, when the Pink-footed Geese decided that conditions were favourable and took off on mass from Denmark early in the morning before passing over Oslo some hours later. Thursday was the day and is the earliest ever date for the big day which 30-40 years ago used to occur in the first week of May. Over the course of 3 hours I counted over 9000 birds heading first NNE over Maridalen and then after the wind changed from southerly to northerly they started heading ENE. I made a real effort to check every flock hoping for something white or red but could only find a few Barnacles and just a single Greylag amongst them. When you spend so long scanning the skies you expect to notice other signs of viz mig but amazingly apart from some Wood Pigeons and some gulls I just had a single Buzzard and two Sparrowhawks which were probably local birds.

Passerine migration has picked up slightly with a few Mistle Thrushes, Twite and Reed Buntings now around in Maridalen but it can feel very birdless at times.

My major excitement this week has been with owls again but they will be the subject of their own post very soon.

hundreds of Pink-footed Geese (kortnebbgås) streaming over Maridalen on Thursday




here with a Barnacle Goose (hvitkinngås) amongst them

the juvenile Common Crossbills (grankorsnebb) are growing and will probably leave the nest within a week. Note however that they have yet to develop the crossed bill of their parents

food time


with the sunny days there are suddenly insects and Goldcrest (fuglekonge) are appearing openly in bushes to exploit this new food source

Lesser Spotted Woodpeckers (dvergspett) are getting quite vocal as they search for mates. I had two very noisy birds yesterday which as far as I could see were both females




a pale Buzzard (musvåk)
my first Adder (hoggorm) of the year

and my first Oslo Small Tortoiseshell (neslesommerfugl)

Woodlark anno 2025

Different species are sending very conflicting signs as to how far spring has sprung. The Taiga Beans (or at least the GPS tagged bird) have moved on to their next staging ground record early and this despite there still being overnight frosts but at the same time only a few Pink-footed Geese have moved through and there have been no significant arrivals of thrushes or finches.

The first Woodlarks arrived at the weekend at their breeding grounds near Gardermoen airport and I paid them homage on Monday although only a single bird showed for me but it showed very well. I would normally combine this trip with a search for the Taigas but I knew they had already moved on so contented myself with the perhaps even more frustrating search for a Bewick’s. I did find one bird after over 30 minutes of searching but as a reward I did get my best views so far.

Maridalen has been very quiet with next to no signs of any new migrants. The Pink-footed Goose flock has finally moved on and a regularly drumming Lesser Spotted Woodpecker is perhaps the only scarce bird around. In the evenings there is still loads of activity from Tawny Owls with a single male constantly singing only a couple of hundred metres from a pair who I don’t think have started mating yet and the female of this pair calls a lot whilst the male sings occasionally.

Bewick's Swan (dvergsvane)

the bill pattern looks to be the same as the third bird from my previous post






Bewicks leading the way and its smaller size is very apparent


Lapwing (vipe) in Maridalen. I have again only seen three the last couple of days

my first Reed Bunting (sivspurv) of the year was the reward of another futile search to find a Stonechat

the pair of White-fronted Geese (tundragås) have reappeared at Bygdøy (the pattern of black barring shows them to be the same) although presumably have never left
