Today Dylan opened the nets by himself because Alix was leaving the station in the early morning, and I wanted to say goodbye to her at the train station. We all hope she will have a great time in Blåvand...


Observations : Today I was on my own for the morning observations. It was a shame for the others, because this morning hundreds of northern gannets were flying past non-stop before my delighted eyes....

We’ve finally had a positive (for birders) change in the weather but it really hasn’t been enough to make the difference we all hope for. Yesterday evening there were a few local showers (but they were a lot less than had initially been forecast) and today was cloudy (but the winds were northerly). It is important to remain optimistic though and remember that you have to be in it to win it. Svellet continues to receive daily visits and today tringas were in triple digits for the first time (220 Wood Sandpipers and 110 Greenshank) although if that was due the change in weather or just the passing of time is open for discussion. The water level is now almost too low and the mud flats risk getting bone dry such that when water levels do rise that they will be covering lifeless mud and therefore be of little use for waders. Ideally we will see daily increases of a couple of centimetres over the next two weeks but what we risk is little change until suddenly around the middle of the month levels are risen by 25cm a day. Twelve Ruff today included only 4 males but they were lekking a little bit and one of them was a very striking white bird which I would have loved to see at a place where photos were possible.. Yesterday also saw the first Little Gull and Yellow Wagtails of the year so we can now look forward to Black Tern and Citrine Wagtail (as I said it is important to be optimistic). Maridalen has not hit the same highs offered by the Pochard which was a one day wonder but a little twitch was required today to see a Shore Lark. Only the fourth ever record and in exactly the same spot as the previous three records which have occurred in the time period 26 April to 4 May it is clear when and where to look if you want to find one in Oslo which does make it a little galling that I had indeed looked at the exact same field only 2 hours prior with the said species in mind and had failed to spot it. Shore Lark (fjelllerke) in the Dale. Only the fourth record following those in 2013,2016 and 2021. There are surprisingly few records of migrating birds in southern Norway but when they are on a field like this (and there are MANY of them) then they are not easy to find. an slightly aberrant female White Wagtail (linerle). There is an excess of black on the throat and breast and grey instead of white cheeks but I cannot make it into another rarer subspecies. It looked to be paired up and in breeding modus


Today the winds were still coming form the west, but slightly from the South so we were hoping for lots of birds moving through Skagen today. Unfortunately, it was very cloudy in the early morning which...

Observations : There were no observations this morning due to the thick fog. Instead, I walked around the inland areas looking for species to see or hear... apart from the common ones... I didn?t spot...

1st May was it turns out not as bad as I thought. In the afternoon a Great White Egret was reported from Fornebu. A good species but not one to make me rush out of the door. However, in the evening I had to drop Jr Jr off at a party which my phone informed me was only a further 7 minutes drive from said Egret. I had little belief that it would still be present given it was a Bank Holiday and Fornebu has become more park that nature reserve but when I turned up I immediately saw it. Nice and a Fornebu tick for yours truly 😊 It was an immature due to its yellow bill and was colour ringed although this I only discovered from my photos and cannot make out any code. I am also unsure of the colour of the ring so cannot find what scheme it is from – it looks black but the only scheme listed on cr-birding.org states it rings on the right leg whereas this is on the left. The Egret can only count as Good as I was twitching but there was a hint of Greatness from two other birds. Three Bar-tailed Godwits had also been reported and I could see two waders sleeping in the bay. I naturally assumed these to be Barwits and paid them no further attention until I was about to go home by which time the evening sun had sunk so much that all birds in the bay were in shade. Their bills were under their wings but never-the-less something didn’t look right for Barwit and I was quite sure they were Blackwits. And indeed they were! They were very brick red and small and were clearly Icelandic birds and I wondered if there had been a mistake with the earlier reports but the two bird theory does apply here. Blackwits are not annual in Oslo and Akershus in spring and most previous birds look to be limosa but in the autumn when the species is far commoner it is definitely islandica that dominates. Godwits of the Black rather than Bar-tailed variety the Great (White) Egret was actively fishing and seemed to find a lot of prey here the rings are visible. A metal ring on the right leg and a dark colour ring on the left leg but what colour is it?
