The sightings and occasional thoughts of an English birder in Oslo

Honey Buzzards
This is the third of my posts on scarce breeding
birds from summer 2021.
I was very privileged to be informed of a Honey
Buzzard nest in Oslo last summer. I was told about its existence early in the
season but had to wait until the young were close to fledging before I would be
shown the nest. Needless to say I got quite impatient and was really looking
forward to the day. The nest location really surprised me in that it was much
closer to the city than I had expected and right over a path (albeit little
used). The species is very secretive during the breeding season and I had
always assumed that nests would be in quite inaccessible areas of the forest
but I clearly need to reappraise that assumption and as we all know assumption is
the mother of all..https://www.youtube.com/watch?v=rSIOE0MsUnU
I visited the nest 9 times and spent in total 13
hours with the birds over the course of 12 days. There was only a single
youngster (I do not know if there had been another that had died) which was
already well grown when I first visited. There is little activity at a Honey
Buzzard nest once the young are so well grown. Prior to my first visit the
female had apparently always been close to the nest but once the youngster was
large enough she also left the nest to bring food.
I witnessed three deliveries of food, two from the
male and one from the female and incredibly enough witnessed what seemed to be
the first flight of the youngster as it left the nest never to be seen again.
Most of the time the youngster was just standing on the nest although towards
the end of the period he was also clambering around on branches in the tree.
Here are a series of videos I took. First is a longer
video (9 minutes) and then a series of short clips that I have previously posted on
Twitter.
11 days before fledging
9 days before fledging
9 days before fledging
7 days before fledging
5 days before fledging
perching away from the nest 4 days before it left
feeding on wasp comb 4 days before fledging
still 4 days before fledging
the day of fledging perched quite a way from nest
back by nest shortly before it flew off
after the youngster had left the nest I explored the area immediately under the nest tree
