Morning observations: Morning Obs on a windy Easter Monday. Picture by Hanelie. It was still a windy morning so we could not open the nets. Instead, we all went to do morning observations. Clara, Rose...

I have often written that Easter is my favourite time of the year for birding in Maridalen and indeed it still is even if that doesn’t necessarily mean it is always as productive. The timing of Easter of course varies from year to year and a late Easter will always be better so this year’s relatively early Easter which has coincided with lots of fresh snow has unsurprisingly not been one for the birding memory books. I have been out early every morning but there have hardly been any new birds of signs of viz mig. The absolute highlight on that score being three Red-throated Divers flying in high up and then circling the lake calling before landing and displaying on the lake. This is one of the earliest ever records in the Dale but in most years the lake would still be frozen until at least the middle of April so the conditions aren’t normally conducive to any water birds this early. In addition RtDs have only recently established themselves as local breeders so we didn’t previously have birds using Maridalsvannet for more than a day or two whilst on migration (and birds heading further inland will not come through for a few weeks) whereas now they are an expected sight through the whole breeding season. Tomorrow’s weather forecast does actually look quite promising so I may have written this downbeat post a day too early. In the absence of any interesting bird photos I will chart the changing weather conditions. me scoping the lake on Wednesday 1st April when it was till sunny lots of snow at 8am on Friday 3rd the fields at Kirkeby on 4th April at 07:18 and the fields at Nedre Vaggestein also on the 4th which unsurprisingly held hardly any birds Kirkeby again on the 4th but now at 0852 when at least the sun had come out but stil no birds and Kirkeby at 0822 today the 5th. Not a pleasant morning and looking over the lake from Nes at 0829. There may have been lots of grounded waterfowl out there but the fog meant their presence or not will remain one of earths great unanswered questions And a video of a drumming Lesser Spotted Woodpecker from before I went to England. A pair is now well established and with luck I will find their nest hole.
We woke up to the sound of the storm howling through the house. Because of the wind and rain, we could neither go out to do the ringing nor carry out the migration count, which allowed us to catch up on...
Ringmærkning: Efter, at vi i går havde haft held til at gennemføre en standardmærkning, ved kun at åbne de net som stod mest i læ tænkte vi, at vi kunne gøre det samme i dag. Vi statede derfor...
Observation:Today we moved to the spring observation spot for the migration count. This allows us to observe the birds more closely. The weather was very windy and cold, but luckily we had a great group...

The weather today was getting quite stormy, with some very strong winds throughout the day. For this reason, we could not ring any birds today, as the strong winds would have made it unsafe for our feathered...
Ringmærkning: Ja, det blev til endnu en blæsende morgen, så vi havde lige akkurat nok net i nogenlunde læ til at kunne gennemføre standarden. Vi fik besøg af tre fugle, hvoraf to af dem var genfangster...

Alix, Alvin and I went out for the morning ringing session. We were unsure about how the weather would be, but it seemed okay enough for us to open the nets. The first couple hours of ringing were really...
Observation: What a freezing morning! We?ve almost turned into icicles despite the shy rays of sunshine. Fortunately, we managed to survive long enough to spot the first skua [Almindelig Kjove] of the...
