The last two days I have visited both Maridalen and Bygdøy. Bygdøy on Thursday gave me both Slavonian and Little Grebe which is a pretty good combo in Oslo (and with the Red-necked Grebe also being reported and Great Crested Grebes at Østensjøvannet then Oslo must have had a record day for grebes).
In Maridalen there is now evidence that ducks are moving with both Goldeneyes and Tufted Duck appearing and the Long-tailed Duck showed well on Thursday although I couldn’t find it on Friday. On Friday the water was dead calm and I was able to pick up 6 Guillemots which must be left overs from the influx last week (even though I haven’t noticed them since). Passerines were also most noticeable with quite a few finches and Yellowhammers on the deck and flyover White and Grey Wagtails and Skylark which are getting on the late side.
On both Thursday and Friday I saw a 1st winter commic tern feeding along the north side of Nakkholmen. I really struggled to ID the bird with the distance making it very difficult to observe features properly (despite the light being OK and me using the scope). On Thursday I saw if from Huk where the distance was 1km and on Friday I saw it from Bygdøynes (also 1km) and Bygdøylund which was “only” 600m. I have it on good authority that a distance of 1.4km is no problem for identifying difficult terns so I really need to up my game if I struggle at 600m….. 😉 The tern had the jizz of a Common Tern although its feeding action was more like an Arctic or marsh Tern and plumage wise it did not have a dark bar on the secondaries but neither were the secondaries bright white as they sometimes are. This bird is probably the same as one seen on Bygdøy on 6 October which caused debate amongst those who saw it even when they had good photos to review. After reporting it as a commic tern (probably Common) on Thursday I have now concluded it is a butch Arctic Tern.
|fantastic autumn colours in Maridalen. It was widely reported that the hot, dry summer would result in trees losing their leaves early and without a splash of colour but that has definitely not happened.|
|Goldcrest (fuglekonge) from Maridalen today|
|Guillemot (lomvi) from Bygdøy today|
|and Razorbill (alke) same place|
|the Guillmot diving (note streaked flanks)|
|and the Razorbill diving (white flanks)|
|the tern at 1km range yesterday with a Common Seal. With these views I only ID'd it as a Commic Tern. My field views had led me to believe it was a Common but this picture seems to show very pale secondaries which is an Arctic Tern feature|
|and today at 600m range when I became reasonably comfortable with it being an Arctic Tern (rødnebbterne)|
|Little Grebe (dvergdykker)|
|Slavonian Grebe (horndykker). The striped head shows this to be a 1cy bird and it just this pluamge that frequently causes confusion with Red-necked Grebe|
|Maridalen's long staying Long-tailed Duck (havelle)|
|5 Long-tailed Tits (stjertmeis) tried to migrate over the fjord from Huk, Bygdøy but chickened out and returned. They then fed in bushed by the beach and showed really well|
|this Twite (bergirisk) was in the same area|
