Lista 2025

 So, what are my thoughts and observations after a long weekend in Lista for the annual bird race and festival?


First I have remembered why I did not visit again sooner after my one and only previous visit in 2017 - it is a bloody long drive from Oslo! What on paper will take just over 5 hours ended up taking closer to eight due to Friday afternoon rush traffic and roadworks.


Secondly, even though Lista might be Norway’s premier birding location when the weekend list of 126 species didn’t include either Redwing or Fieldfare then it is clear Maridalen ain’t that bad either.


Third, I haven’t quite lost the edge yet and again bagged the title of Norway’s second best birder😉 in the evening quiz.


Birds of the weekend were Pallid Harrier, Red Kite, Great White Egret and a Barred Warbler (in the hand) and a 50 minute drive gave me a Norwegian tick in the form of a long staying and blinged up Ring-billed Gull.


We had three mornings of migration watching around the lighthouse and each was different. On the first two days there were lots of tits wanting to migrate with Coal the most numerous and also good numbers of Willow. There were also Nutcrackers on the move and a flock of 19 flew high out to sea towards Blighty. Siskins, Chaffinches, Swallow and Meadow Pipits were perhaps the most numerous birds but there were also good numbers of raptors with Sparrowhawks and Kestrels particularly numerous. On our last morning the easterly wind was quite strong and there was less viz mig but there were suddenly Wheatears everywhere.

This Ring-billed Gull (ringnebbmåke) turned up in Norway in March 2023 and received its bling shortly thereafter. It has been seen regularly (at different times of the year at 2 sites 200km apart although also goes missing for months on end and has only been reported at one other location

It looks like it has a black rubber band on its bill

Bopping geese

Tomorrow I am off to Lista for their annual Bird Race. This will be only my second ever visit to what can probably be fairly described as Norway’s premier birding locality and definitely the home of Norway’s most famous bird observatory. If I am lucky I will also win the evening quiz and be crowned Norwegian Birding Champion 2025 (after being runner up on my previous visit in 2017 although most likely I will be knocked out in the early rounds... The birding should be good though and with a bit of luck a rarity or two will turn up when we are there.

Local birding has been pretty good though this week although a hoped for rush of seabirds this morning after a night of strong southerly winds revealed not one single non-local seabird and the only real unexpected sighting was a juvenile Honey Buzzard battling into the headwind to cross from Bygdøy to Nesodden.

I have been to check on the Taiga’s a couple of times and found them to be on the same stubble field that they used for the first time last autumn and then also used this spring. This is quite typical that they will change preferred field in one season and then also use it the following 1-2 seasons and I would not be surprised if next spring they choose somewhere else. When they are on a stubble field they can be surprisingly difficult to count accurately and they have also had both Canada and Greylag Geese, and a hybrid between the two, in amongst them but in the end I concluded that the flock size was still 129 meaning no additions or depletions.

Visits to Hellesjøvannet with raptors in mind turned up trumps with a Red Kite and lots of sightings of Hobbies, Marsh Harriers and especially Common Buzzards with one “kettle” containing 18 birds.

I have only had fleeting visits to Maridalen but had a real head scratching surprise today when I discovered a family of four Whooper Swans on a field and then river (they were very shy) 4km away from where I had last seen the intact family on the lake. The young were large but not fully grown and I am sure could not fly meaning they must be the Maridalen family but I don’t know how to explain the sighting of 18 August and my subsequent sightings of just an adult pair or no birds at all.

Red Kite (rødglente) at Hellesjøvannet. Only my second in Akershus (I have had more in Oslo) and the first one I have managed to photo. Clearly not a juvenile but other than that my knowledge of moult and plumage in this species doesn't allow me to say any more
I was very lucky to come across this juv Goshawk (hønsehauk) eating what looks to be a Jackdaw (kaie) right by the road at the Taiga Bean place.

a family of Cranes (trane)


just a single Pochard (taffeland) at Hellesjøvannet and very few other birds including only 2 Great Crested Grebes suggests to me a lack of oxygen, and life, in the water. There were 3 visits from at least 2 Ospreys and they left with a fish each time on their first attempt which I reckon means there were fish at the surface gulping air

the highlight of today's seas gazing at Fornebu was these juvenile Knot (polarsnipe) that flew in from Huk and landed on the rocks in front of me








I was not expecting to see these today in Maridalen. I will try to see if the beak patterns allow me confirm that these are the regular pair

the flight feathers of the juveniles are not yet fully developed so I am quite sure they have not flown in from somewhere else

Maridalen Honey Buzzards

My efforts to locate the Maridalen HB nest have eventually been successful but after putting in the ground work myself without finding it I phoned a friend and outsourced the glory shot to Per Christian who was able to send me photos of the nest whilst I was in Tromsø this weekend.

I had had a number more sightings and felt certain I have narrowed down the area to a radius of under 250 metres. In addition to, I think, my periods watching in the nest area coinciding with periods when the adult(s) were not making frequent visits to the I believe that the adults don’t fly directly either to or from the nest and probably fly quite a distance through the forest which will of course make finding the nest more difficult. Before finding the nest I did have confirmation of nesting when I saw a juvenile fly out of a wood that was close to my watch point on 24th (although it would turn out this was not where the nest was) and then slowly circle before flying north to the same area the ad Male has frequently flown to.

 

The young are supposed to spend quite some time returning to the nest for food deliveries (although I have not noticed this with the 3 nests I have followed before) so continued observations would hopefully reveal this and there may well have been another unfledged juvenile still on the nest (at this time both young were still on my other nest). And this is what PC witnessed on 30th August when he saw an adult flying into a wood and then heard a young begging for food before finding both adult and young on the nest. Both then flew off and the young continued begging and the adult alarm calling elsewhere in the wood. The nest was only 100metres from where I had spent around 11 hours, spread over 4 days, watching and was in a wood I initially thought could hold the nest based on where I had seen birds flying but a walk through the small wood revealed no large spruce trees which I thought were the preferred nest tree. They had however chosen a deciduous tree though - an aspen (osp) – and the nest was low down (no more than 10metres up) . Upon seeing the nest when I visited on 31st I realised I had actually noticed it when I checked this wood but hadn’t even bothered raising my bins as I assumed it was just a jumble of twigs (it was in the wrong type of tree and too low down….). So, I have definitely learnt a lesson.

 

The fact that birds have bred in Maridalen both this year and last (and who knows maybe before) and have therefore been present end of May/beginning of June to end of August/beginning of September without hardly ever being seen is quite extraordinary and I believe owes more to their cryptic nature than my dire field skills…😉. The nest is also close to paths and a farm and it yet again amazes me how close shy raptors will breed to people.

I have only with certainty seen the male of this years nest and it is clear from his plumage that he is the same bird that I saw last August flying with wasp comb into exactly the same area as this years nest. I did see and photo a female last year that I assume is his mate but had no definite sighting of a female at all this year…

Hopefully they will nest again next year and this location will be much easier to observe than the other, regular, nest and allow me to document even more of the life cycle of this enigmatic species.

 

The juvenile on 24 August is the (joint) second earliest photo documented 1cy Honey Buzzard in Norway and may well be the first fledged bird as the photo from 20 August looks to me to be of a bird taken close to the nest.

There are a surprisingly high number of records of 1cy birds before 24 August though including 6 in July, one of which is «approved», 13 in the first week of August of which 3 are «approved» and 15 in the second week with 5 of these «approved». All of these records should be expunged from the records and there are many names as well as records committees who should update their knowledge on the breeding cycle of Honey Buzzards and what 1cy birds look like… (the same applies to Hobby and don’t get me started on all the impossibly early spring records of both of these species..).

the empty Maridalen Honey Buzzard (vepsevåk) nest. Low down in a deciduous tree and easily viewable. Hopefully it will be used again in 2026 - just 9 months to wait...


Mobile shots :

I cannot see why they have chosen this branch in this tree but then again I'm not a Honey Buzzard
