A sea gaze with a result of sorts

Yesterday it blew again from the south so I gave sea gazing a go again. Two young Little Gulls battling into the wind were my reward which I must admit was better than I had hoped for but otherwise there were no birds that seemed to have been blown in. I watched from Torkildstranda by Drøbak which allowed me to sit warm and dry (it was bucketing it down at times) in the car and may become my new go to sea gazing spot. In the video you will see the bird flying past a couple of windsurfers. When it blows around Oslo and you decide to sea faze you can almost guarantee that you will also see wind surfers but very few other people. Birds and wind surfers must be the only people who scour weather forecasts looking for storms.

The Pygmy Owl in Maridalen showed in the rain as it tried to shelter by the trunk of a tree. It was really wet and looked very unhappy with one eye open and the other closed.

Three videos - the first is a long edit of it in the rain and the other two short clips showing specific beahviour

The Marsh Tit continues to show well and continues to do very little to give itself away. A hybrid was documented genetically (a world first!) on the other side of Oslo from 2020 - 2023 and I guess this bird could possibly also be a hybrid (based purely on it giving the species specific call so infrequently) but I see nothing in the plumage to suggest so. Marsh Tit is declining all around Oslo so the chance of hydridisation will probably increase if lone birds do not find a mate. In my previous post I wrote that the closest population to Oslo was in Lørenskog but no birds have actually been reported from here since 2018 illustrating the decline of the species.

I keep attempting to take good comparison pictures of the two species and am perhaps getting slightly better at:

both the Willow Tit (granmeis) on the left and the Marsh Tit (løvmeis) are nearly in focus although it would have been nice if both were in profile

darn twig

and if you can't get them right next to each other in the view finder there is always photoshop

From next week we are forecast to have negative temperatures and perhaps snow which will hopefully shake up things on the bird front.

Geese, geese, geese

I have been drawn back to Nordre Øyeren daily now in the hope of uncovering something rare. The numbers of geese are just enormous and you can see them either feeding on stubble fields or resting on the water at Svellet. There are at least 2000 each of Barnacles and Greylags but probably a lot more as well as 400 Canadas. Finding something scarcer amongst all these has proved tough going but I have now found a single White-fronted Goose, single Bar-headed, single Pink-footed and 3 Greylag x Canada hybrids. I have only found one bird with with a collar - a Greylag ringed in Germany in 2021 and since either close to Oslo or in Germany.

I have spent too long looking at the Canadas and have got a headache at the amount on variability amongst them with some birds definitely looking «wilder» than others but all probably within the variation of size and plumage of a feral population that probably has little genetic diversity.

this Canada looked very interesting from afar 

but closer up I wasn't s sure

and this one while not being so dark also looked quite different

enormous numbers

Water levels have risen a lot due to heavy rain and there is no longer mud in Svellet so waders and dabbling ducks have vanished but there are now 4 Little Gulls and also 4 «commic» Terns (I remember as a child hearing the term Commic Tern and not being able to find it in my bird book. It caused me lots of confusion for a long time until I finally plucked up the courage to ask an older birder what it was and found out it was from COMMon and ArctIC and referred to unidentified birds of the species pair. I also remember very soon after calling out “Commic Tern” and it being a white dove….). I initially thought there were 2 Common and 2 Arctic but with better views have now come to the conclusion that there are at least 3 Common and the fourth bird is also most likely a Common. It has been quite a learning experience where I relied too much on jizz and behaviour to start with.

3 f the 4 Little Gulls. All were 1cy

this 1cy tern with grey secondaries must be a Common (makrellterne)

I have had 10 species of raptor which is a good showing and my first Great Grey Shrike of the autumn.

a very distant, but very smart, male Hen Harrier (myrhauk)

Peregrine (vandrefalk) and a pale Common Buzzard (musvåk)

this immature White-tailed Eagle (havørn) flew over Svellet

and a bit later I found it on a field that had previously been covered in geese with just a few crows for company

Merlin (dvergalk)

I have also had a couple of attempts to locate the Taiga Beans but have failed. I assume they are still around as it would be record early if they have already left and I remember that in previous years the GPS tagged bird(s) have shown they have often used one particular field that is very well hidden and that I have never tried to get to as I am certain it will just result in flushing the birds – they may well be using it again.

 

I have only had a couple of quick visits to Maridalen but a perched and then hunting White-tailed Eagle was a very good sighting.

the Crane (trane) family is still feeding in Maridalen

it is very unusual to find a perched White-tailed Eagle in the Dale

The last week

The last week hasn’t just been about big owls and rare waders. I have continued visiting Svellet and Nordre Øyeren but despite continued low water levels there have been surprisingly few waders with now zero Wood Sandpipers!!! Water levels are now rising about 10cm a day so the mud at the edges probably just has no food in it. Also with spring having come early and no rain to force birds down many birds are probably also flying directly to their breeding sites. The first Temminck’s Stint and Dunlins have turned up though and Redshank have become the commonest wader.

Yesterday, I had my first visit of the year to the islands and a 2nd summer Little Gull on Gressholmen was a real highlight and gave much better views than the birds in Svellet last week.

when I first saw this gull with an extensive black hood, red legs, a pink wash on the breast and black in the wing tips I thought I had found an adult Bonaparte's Gull. A check in the scope though showed it was "just" a 2nd summer Little Gull.

and comparison the views that I managed at Svellet last week where I must admit to being quite chuffed that I actually got a photo which shows both an adult and a 1st summer. This video gives an idea of the viewing conditions at Svellet:

A Redshank (rødstilk) at Gressholmen was the only migrant wader and for me this has been an awful spring for waders in Oslo with me still not having seen Greenshank or Whimbrel. Water levels are finally falling at Maridalsvannet revealing some muddy edges but I fear it is too little too late

Thrush Nightingale (nattergal) on Gressholmen in exactly the same place as they bred last year so presumably the same male

there were quite a few young birds to be seen on the islands including the first Black-headed Gulls (hettemåke) with three young visible top left

this must be one of the larger BhG colonies left in the Oslo area

at Østensjøvannet which used to hold many hundreds if not thousands of pairs of nesting Black-headed Gulls I could only find 7 occupied nests today with five in this tree. The especially maintained islands that they used to use are now empty

this colour ringed BhG at Østensjøvannet received its bling at Bowness-on-Windermere in the UK in December 2019 and has subsequently been resighted there every winter and in Oslo in the summers

Eiders (ærfugl) have had young very early this year. Normally the adult males would have moved off but here they were displaying to the females

A Dunlin (myrsnipe) and Redshank (rødstilk) at Årnestangen in the same place where I found the dowitcher

and my first Temminck's Stint of the year also at Årnestangen

it is not easy being a breeding Ringed Plover (sandlo) in the Oslo area. This bird at Fornebu had chosen a fenced off area away from human disturbance and has hopefully been succesful. This picture was taken just a few days before the young should have hatched and a visit a week later revealed no birds at all which hopefully means they have led the young somewhere even safter

when on the islands a Ringed Plover flew up in front of me and I saw that it had flown up from a nest which contained 3 eggs

hopefully they will be successfull

in Maridalen there is now a third Lapwing nest. This is one of the pairs that lost their nest to the plough relaying. I still think that the other pair that seemed to lose their nest may actually have young in the long grass although I have yet to see them. A fourth pair is now hanging out at Kirkeby and will hopefully nest there

the Long-tailed Tit (stjertmeis) nest that I found had an adult in it on 8 May and I assumed it was incubating. However subsequent sightings mean she was most likely brooding..

as on 13 May the young were being fed by both parents at the opening to the nest. This must be very early

water levels at Svellet are rising by 10cm every day and the party is ending

this is how it looked on Tuesday 13 May when I last visited and as can be seen on the graph water levels have risen more than 20cm since then which probably means most of the mud is now under water
