Go Grozzas!

I've had some feedback that I didn't sound particularly happy with my sea gazing yesterday which did after all included a Grey Phalarope which is a VERY good bird - so good that it is only my 4th in Norway (3 of them have now been from same place - Krokstrand) and the first in Oslo & Akershus for 6 years. I guess I have overly optimistic expectations based on just one or two epic seawatches close to ten years ago and am forgetting how dire sea gazing usually is close to Oslo so should be happy with what others would describe as a fantastic day. One thing I really missed was the complete lack of skuas. I know that the global population of Great Skuas has been hugely affected by avian flu but there is also clearly something up with Pomarine Skua which used to be an expected feature of late autumn storms but nowadays I hardly see an autumn record of 1cy birds AT ALL in the whole of Norway. I have heard that one reason that Steller's Eiders are suffering is that Pomarine Skuas are predating them on the breeding grounds due to a repeated lack of Lemmings on their Siberian breeding grounds. What I don't know though (and maybe know one knows due to the dire situation in Russia) is when the last time Pomarine Skuas had a successful breeding season. 

Anyways yesterday was a GOOD day and so was today because I got myself a Grozza. It was a sunny day with little wind and I was determined to find one so with the Beast in tow went walking in the forests of Lillomarka. And I did not have to wait long - just 10 minutes after leaving the car I heard one of the most magical sounds known to man and then saw the little beast of a bird. It was in an area of mixed spruce/pine forest with no rowan berries and although they eat the buds of coniferous trees I think the seeds of rowan berries are preferred so I reckon birds are just passing through the forests and will eventually settle in the city. I later heard another overflying bird(s) so they are clearly on the move as hoped/predicted. Otherwise it was eerily quiet in the forest but I did hear and then see a Hazel Grouse and heard a distant hooting Pygmy Owl so there is still some life in the forest.

The video has the magical sound of the Pine Grosbeak (konglebit) and the Hazel Grouse (jerpe):

Hazel Grouse reunion

I have previously written that Hazel Grouse are a challenge to find this year. After having my last meeting with my previously reliable male (and his normally far shyer mate) in February I have really struggled to find birds despite checking many territories that have been occupied in last 20 years or so. It does seem to me and others who know the species that it has become genuinely far scarcer in Oslo’s forests and quite abruptly. Why this should be is unclear. There has been extensive forestry work in some areas which have changed some territories but there are also empty territories in nature reserves where everything looks the same as it always has.

It was therefore a big relief to find two birds in the same small area yesterday. Both sang and almost in duett with one song being notably louder and clearer than the other. I only got to see the louder bird well and this a nicely marked male with a clearly visible red skin patch above the eyes. As I did not see the other bird well I was unsure as to whether I was hearing two males or a male and female and also whether one of them could be my previously faithful male (we were only a kilometre from his old territory which now seems empty). Birds of the Western Palearctic (BWP) tells me though that females do not sing like males and it also tells me that each males song is different.

This video has the sound of both birds singing and sometimes on top of each other. It also features the Beast and as I have previously written I think having dog in tow does help find Hazel Grouse as they seem to show curiosity towards the animal:

I have previously noted that Hazel Grouse song varies but had never thought too much about it and hadn't worked out that the variation is between males and not within how each male sings. When I listen to my own recordings I can hear that Old Faithful sounds the same on each recording I have taken between 2021 and 2026 whereas other males sound slightly different. Neither of these males songs is the same as Old Faithful which can be heard here this February and here back in 2021 the year I found him and his song can be heard to be the same 5 years apart. (I think I need to go through all the videos I have with singing birds to see if I can identify the same individuals over time from other territories I have visited over the years)

Hazel Grouse are normally to be found in male-female pairs so finding two males together is odd but autumn is when pairs are formed and there may well have been a female nearby that they were trying to impress or they could have been competing over territory. That one bird had a clearer and louder song than the other suggests to me that bird with a weaker song may have been a bird of the year who was only just starting to sing.

Here is a video of the stronger singing male (but not of him singing) and then some photos of him.

Taking stock at home

Maridalsvannet on the morning of 20th May

In Oslo it seems as though migration has come to end with rain and southerly winds causing absolutely nothing exciting to turn up. Svellet also still has mud but without there being a single wader reported this morning. Even though the period of quantity of passage birds has passed we are definitely entering the highest quality time and yesterday a stonking male Black-headed Bunting was pulled out of a mist nest in the garden of a twitcher who I had no idea had a ringers licence.

Almost all breeding migrants have now turned up with the first Rosefinches, Red-backed Shrikes, Marsh Warblers and Nightjars being reported now even if I have yet to see any of them yet.

My focus has now turned to locating breeding birds both for my own benefit and also a busy period of guiding that I have coming up. Hazel Grouse has been a real nightmare this spring. A long walk on 17 May with Mrs OB and The Beast took me past 8 or 9 territories where I have previously had the species but with not a single bird being found. Today I checked 3 territories in another area including “my pair” and did finally pull a bird out of the hat which I feel confident of being able to find again. Three-toed Woodpecker has also been a headache this year so a female that gave herself away tapping on a tree was a relief but she flew off without me being able to track her to a nest.

The two pairs of Black Woodpeckers continue to entertain with the one pair still applying the finishing interior design touches to their property and the other pair working hard to fill three noisy mouths with food. In this video you can see the male using over a minute and a half to feed them individually with food he is clearly regurgitating into his bill.

Hobby (lerkefalk) today. I have only seen a single bird and heard no calling so do not believe a pair has returned yet

Black-throated Divers (storlom)

I watched a Wood Warbler (bøksanger) with nesting material in its beak fly onto the ground here. Can you spot the nest?

here it is and is of a similar construction to Willow Warbler (løvsanger) and Chiffchaff (gransanger) nests I have previously found

On the Lapwing front there are still two birds incubating and seemingly three broods of 4,1 and 1. With the two broods of single young the siblings were lost very early on but the remaining young are now half grown and will hopefully make it. The brood of 4 is a few days younger but the parents have done very well to still have all four alive.

Post guiding silver platter

As is typical after guiding, the species that were difficult to find have served themselves up on a silver plater in the following days….😂

 A male Three-toed Woodpecker has showed exceptionally well in Maridalen in a small area of flooded forest with dead trees well away from the species normal areas and the exact area we checked unsuccesfully on Saturday for Black Woodpecker (and had no other ‘peckers either). And Black ‘pecker which was our most striking miss at the weekend has of course also shown well….

 Pygmy Owls have just been waiting for me on roadside trees and two in a day was so noteworthy that it required a comment on eBird (our local reviewer is a meticulous young man😉).

 A visit to the Hazel Grouse saw me heading straight for where we had the male on Saturday and what do you know - he was in exactly the same tree and I only used 10 minutes from leaving the car to see him rather than nearly 2 hours. He was high up in an alder tree but I was able to clamber up a slope and see him nearly at eye level for a long period of time.

 Two different Marsh Tits still in Maridalen maintain the hope of the species establishing itself although they are not a pair and one of them is the (mostly) silent bird which always is hanging with Willow Tits and which best case has an identity crisis and worst case may be a hybrid. The other bird loves to call and is either on its own (although earlier there were two vocal birds together) or with Blue Tits.

 Jack and I visited Owl Road last night in glorious positions - a cloudless starry night sky, -16C, no wind and even a tiny slither of a moon. Three Tengmalm’s Owls meant a 200% increase on 9 days earlier but we had no other owls (it was the same date last year when I showed Jack his very firstGGO).

 The sun has been shining but temperatures remain a long way south of zero so early spring migrants are still to arrive but from the middle of next week we are forecast to have temperatures above zero and some rain. This will probably be all that is needed for the first geese, Snow Buntings, Skylarks or Starlings to show up if there are suddenly snow free flecks on the fields.

only three toes

the rings on this tree suggest that a Three-toed has been in this area quite a while...

Moose have also showed well but were absent at the weekend

I attempted some flight shots and nearly succeeded in a sharp shot

my Hazel Grouse (jerpe) photos were nothing special but I am happy with the videos which have him singing and eating snow

Taiga guiding

This weekends guiding had me praying to the Bird Gods and wondering what I had done to displease them before eventually being giving their slightly limited blessing.

Martyn, Jo and Stella had come to Oslo to see our special winter birds and especially Hawk Owl and I was determined they would leave happy.

On Saturday the target was the specialities of Maridalen and surrounding forests and on Sunday it was the taiga areas of Hedmark. 

Saturday was sunny, windless and cold with temperatures down to -20C in the forest and on Sunday it was forecast to be same but ended up being cloudy with occasional snow and temperatures down to -23C. We experienced near white out conditions a couple of times when we were in low cloud and whilst cool to experience it was not the best conditions for finding birds.

On Saturday the targets were Hazel Grouse, Pygmy Owl and interesting woodpeckers. Hazel Grouse took an hour and a half and just as we were about to head back to the car empty handed I had one last attempt and finally a bird sang. It then took another 15 minutes to find the bird but it then sat directly above us in a tree and was so unaffected by our presence that it never even looked down at us.

Otherwise, the forest was very quiet with no peckers of any type.

Maridalen gave us Crested and Willow Tits, Goshawk, Dipper and Hawfinch and eventually Pygmy Owl which showed very well but far too briefly.

So, the two main targets were delivered but peckers disappointed.

 

Sunday we had a two hour drive to the taiga and I kept hoping the forecast sun would appear the further north we drove but instead we just saw lower and lower cloud. The forests were covered in thick snow but where were the birds?!? We slowly drove the forest roads for over 4 hours and saw only 11 species and only around 40 individual birds of which Bullfinches made up half of these…. 

For a long time a female Capercaille was the top bird before a Three-toed ‘pecker gave itself up but far too briefly and partly made up for the lack of peckers the day before but we still failed to see a Black. But where were the taiga species? Hawk Owl (which was the #1 priority for the whole weekend, Pine Grosbeak and Sibe Jay?

People were dozing off in the car but I was still searching for a lump on a tree top and FINALLY a Hawk Owl gave itself up. Only 30 metres from the road it showed just long enough for me to set up the scope so its yellow eyes could be studied before stooping down and never reappearing. That was the last bird we saw in the forest and a fitting end to the trip but I would have liked to be able to find Grosbeak and Sibe Jay. It wasn’t through lack of trying and if the sun had been shining then I think we would have had more birds perching on tree tops but we play with the cards we are dealt with.

 

Pictures were not my priority but here is a flavour of the weekend.

can you spot him?
