OSLO BIRDER: Nightjars anno 2023

We are following a much liked and well trodden path and spending the first week of the (school) summer holiday at the cabin at Hulvik south of Oslo. I’ve done a bit of butterflying without seeing anything too exciting and the only birding has been a couple of nocturnal trips. We have been coming here almost annually for around 15 years and I have engaged in nocturnal trips for at least 10. Nightjars were always a species I was listening for but it was only 2 years ago that I discovered them here for the first time. Last year we also had them so I was of course expecting to find them again this year and as always I was hoping to see them before it gets too dark although that never happens as I hope.

The reason for the sudden appearance of Nightjars in the area must be because of extensive recent forestry work clearing away large areas of planted spruce and revealing more natural scattered pine trees on sandy soil which is a great habitat for Nightjars. Hotter, drier summers are probably also helping the species in Norway which is right on the northern edge of the species range.

This year my first trip with Jr on Sunday evening started off disappointingly with only a distant singing bird when we checked the area from the last two years. Finishing our trip though and not too far from the cabin we saw a female hunting along the road and stopping heard a male churrring nearby. We then had good views of the male wing clapping over us although by this time it was gone midnight and rather dark (or at least as dark as it gets in mid summer here).

Monday night it poured down with rain but I was ready to go on Tuesday night at 10pm. I was hoping that the poor conditions the previous night may have left them hungry and would increase the chance of early activity. For once I was right with a bird hesitantly churring already at 22:15 and before sunset! I managed to get my best pictures to date of the species (helped in no small part to the fact that Conor C has very kindly lent me his Canon 5D IV). I was aware that there could be a nest on the ground in the area and scanned with the thermal imager to see if I could locate the female. I didn’t but suddenly I saw an animal and there was badger walking right towards me! Unfortunately it sensed me as I raised my camera but seeing it walking along sniffing the ground highlighted the threats that ground nesting birds expose themselves to. Of course if we didn’t remove all of the apex predators (wolves and lynx) then there would be fewer badgers and foxes and more balance in nature but humans aren’t good at natural balance.

I was a happy man as I headed back to the cabin at 11pm (very early by nocturnal birding standards) but things then got even better. Getting out of the car there were juvenile Tawny Owls begging for food right by the cabin. There were 3 and their begging just got louder and louder during the course of the next hour when they didn’t seem to be fed at all. But that was not the best of it - a Nightjar flew over and then one started churring nearby!! Plus Woodcock and barking Roe Deer (which set the Beast off) and I now realise that tonight I can do my nocturnal birding from the cabin veranda with a glass of wine in hand #glambirding
