I have settled into a birding routine this week which has resulted in my visiting Sørkedalen daily (a very unusual occurrence). The reason is that I have been searching for a supply of Hawkie in Oslo and have decided that in addition to driving around Maridalen looking for a roadside or treetop dealer I would also check out its larger and probably more suitable sister to the west. In addition to visiting the two dales I have also had daily visits to Tryvann to follow the progress of the Pine Grosbeaks and to Fornebu where I have a hope of finding a rare warbler but in reality just end up looking at Jack Snipe and Kingfishers although a Snow Bunting was an enjoyable find on Wednesday.
Now my attempts to find a Hawk Owl have not been successful and
neither have I found any other tree top perching mouse eating predators such as
Great Grey Shrike or Pygmy Owl so I do not think there are good numbers field vole
this winter. Nevertheless the theory for Hawk Owls turning up in the lowlands
this winter is that there is a cyclical low in bank vole numbers in the higher
forested areas this winter and that the Hawk Owls are forced into the lowlands
to survive on a diet of field voles. I do not know how correct this is but the
arrival of Hawk Owls into the lowlands of southern Norway this winter was predicted
so it does sound like the theory holds water.
Anyways, my failure to find one doesn’t mean I haven’t
seen one 😊 and in Maridalen no less. I was at Tryvann looking
for Pine Grosbeaks (it was glorious sunshine and there were a number of
photographers on the same errand) but before I could find any I had a phone
call that led me back to the car and heading for the Dale. It had gone missing
by the time arrived but a bit of searching found it quite quickly and it proved
to be high quality Hawkie and allowed itself to be enjoyed at a nice distance
whilst it stared intently at the ground beneath its chosen perch. It made one unsuccessful
dive for prey but I suspect it will move on tonight in search of a better
hunting ground. A flock of 17 Pine Grosbeaks flying over rather made my day!
This is not just my first Hawk Owl in Oslo this year but
also my first in the country. #Oslo2024 marches forward to 206 species (204
post redpoll lump) and 210 now looks like a possibility!
