Oslo update

Returning to the local patch after a trip to see the specialities of Hedmark is always a bit of an anti climax but things have been quite rewarding and the weather forecast suggests more may come.

Wader passage through Maridalen is coming to end with another Ringed Plover on Sunday and just a single Wood Sandpiper today but there is still time for a Broad-billed Sandpiper to turn up. A trip to Svellet on Sunday amazingly revealed just a single Common Sandpiper (in stark contrast to the day before) but the rain still has the potential of bringing down something good.

The Lapwing situation in Maridalen is looking good. Yesterday, I discovered three broods (4,4 & 2) feeding along the lakeshore with parents in attendance and the two nests that were made after the farmer ploughed still had sitting birds. My assumption at that time was that the very first nest had failed, and that the broods were from the remaining three nests that the farmer saved. Today though there was a bird sitting on one of those nests (the one I had originally overlooked) and given that the young in the brood of 2 were slightly larger than the other 2 broods my working assumption now is that the nest that I originally thought was abandoned is the source of the 2 larger young, the two broods of 4 are the birds I saw when they hatched on Thursday and that the bird in the fourth nest was just not sitting the times I have checked on Sunday and Monday (this is possible as the female leaves the nest to feed). Time will tell but there currently still looks to be the chance for 3 more broods 😊.

Raptors have been slightly more visible with Buzzard, Osprey, Sparrowhawk, Goshawk, Kestrel and Hobby in Maridalen plus a bird that I thought at the time was my first Honey Buzzard of the year but provided a cautionary tale in trusting too much in jizz (see pictures lower down).

A couple of trip to Østensjøvannet revealed an insect hatch with lots of Black-headed Gulls, Swift, Swallows and both Martins hawking over the water and I have been diligently searching them for something rarer but a single Common Tern was the best I could come up with. Two adult Peregrines flying about together was a strange sight and perhaps a sign that the pair that breeds in Østmarka have failed.

Bird of the period though was none other than a new Maridalen species for me. No, not a House Sparrow ;-) but an Arctic Skua (tyvjo)! A most unexpected species but not the first for the Dale as one was photographed on 10 June 2017. I remember the photo appearing on Facebook with confirmation sought for species and I remember wanting confirmation of location! Today's bird was picked up over the forest ridge to the west of the valley and through the bins I thought I was looking at a falcon of some description. Picking it up in the scope proved rather difficult but when I did it was not the Hobby I expected but a skua and the jizz, extent of the white wing flask, length of tail and all dark plumage made it a clear adult dark phase Arctic. Some trees then got in the way (where I was standing was not the best place to be scanning the skies) and as I fumbled with the camera and waited for it to appear again that was the last I saw of it.

This afternoon the wind turned to the south after having previously been easterly and it rained so after dinner I headed for Svellet with high hopes. When I arrived at 18.30 it was still raining and visibility was poor but I scanned and scanned and could not find a single wader and a Common Tern was the only tern or small gull I saw. I then checked Merkja which was equally dead before I remembered to send a message to Anders about how quiet it was as we had messaged earlier in the day about checking out Svellet in the evening. He replied immediately along the lines of oh shit, I've just got here... I then headed back to Oslo and thought I would see if Maridalen had anything to offer. Twenty minutes later as I arrived in Maridalen Anders rang and I knew he had found something - a Black Tern. I considered about driving back but instead used this as motivation to find something in the Dale. It was soon clear that birds had arrived since this morning and 2 Temminck's Stint, a Redshank, a Greenshank and a pair of Velvet Scoter was a good showing. Tomorrow also looks like it could deliver but then again I am forever optimistic when it concerns birds.

what would you make of this raptor? Long tail, small protuding head, narrow wings. Well I took it to be my first Honey Buzzard (vepsevåk) of the year until..

I lightened up some photos and saw it was a Common Buzzard (musvåk). The streaking on the breast shows it is a young bird and they do have much narrower wings which has caused me problems a number of times in the past at this time of the year

the young have hatched in the Black Woodpecker (svartspett) nest and could be heard calling when dad came

these Common Scoter (svartand) rested on the lake all day on Monday but were clearly restless and waiting for night to continue their migration

A single Crane (trane) in Maridalen instead of a pair. Are they still attempting to nest after all?

first brood of Goldeneye (kvinand)

Hobby (lerkefalk)

this year seems to be very good for Icterine Warbler (gulsanger)

Little Ringed (dverglo) and Ringed Plover (sandlo) together in Maridalen - this has I think only been witnessed once before

Starlings (stær) are a common breeder in Maridalen usually using old woodpecker holes or nestboxes but this one has squeezed into a hole in the church ruins

the 1st summer White-fronted Goose (tundragås) looks like it will stay the summer and moult at Østensjøvannet
