Keen to overcome my own frustration I headed up into Maridalen this morning thinking there was a slim chance that blackie was still going to be there. I really struggled to find the object of my desires and drew a blank when I looked on my way into the valley but it eventually showed on my way out. It was exactly where it was seen yesterday evening but seemed to have a feeding circuit and would disappear for long periods before popping up again. A female coloured bird it could conceivably be a 2cy male but it has a very distinct wite wing panel. This is a feature of adult males - young males lack this and females should only show an indistinct wing panel. The extent of this birds wing panel suggests it is maybe an old female which in many species can have more advanced plumages. Its favoured area was where slurry from the farm animals was congregating and this area was also popular with a couple of Robins (rødstrupe) and White Wagtails (linerle) although the later didn't like to share and kept chasing blackie away.
The Pink-feets (kortnebbgås) were still on the fields but otherwise Maridalen was very quiet with far fewer thrushes. I did have a Maridalen first though although only a behavioural one with yesterday’s GC Grebe (toppdykker) now having company and they were displaying. These birds are most likely on migration but if not would be a most welcome addition to the breeding birds of the valley.
My attempt for the Bean Goose that was found yesterday at Bygdøy was less successful. Although seen earlier in the morning by the time I arrived there were some people working on the fields and the Greylag Geese it was with were not to be seen either so presumably had been disturbed. Whilst searching for this I got a message from Rune that he was in Maridalen and was watching a Great Grey Shrike (varsler) so I headed back there again and didn’t see that either. No wonder I don’t like twitching and this was only my own little version of County Year Tick listing although with me there is of course only one County that counts, namely Oslo. So I tried to Oslo Year Twitch three species today and achieved one – I should stick to patch birding!
|Black Redstart (svartrødstjert) - female plumaged but is such a prominent white wing panel normal for a female? It is also not normal for a young male so perhaps this is an old female?|
|the white wing panel is formed by one mostly wite tertial feather plus white tips to secondaries|
|barely visible but with the Oslobirdermobile in the background|
|displaying Great Crested Grebes in Maridalen - a first?|
|adult male Goshawk (hønsehauk) - today's only raptor|
|Two of the 28 Pink-footed Geese (kortnebbgås) still on the fields at Skjervan|
