Great Grey Owl madness in Maridalen
I finished my post on
Monday by saying that I had been unable to find the GGO that day. Well even
though I had been unable to find it the bird was seen by a local around sunset
and then on Tuesday was seen at both sunrise and sunset (not that there is much
sun involved in these events at the moment) although I was unable to find it
in between. I did see it at sunset though and then returned early on Wednesday morning
when I was able to follow it for the entire day. I had it hunting from before
sunrise and then at 09:45 it retired into the safety of some spruce trees and
slept on the same branch until 15:00 when it then came out and hunted again (no
wonder I had not been able to find it on Monday or Tuesday during the morning
as I didn’t start looking until 10am at which time it would have retired for
its nap). I did not witness a successful hunt but I assume it is also hunting
through the night. The fact that it is sleeping and not hunting in the day is an
indication though that it is finding enough food at night. I still haven’t seen
any mice or their tracks in the snow but did hear one today.
I had been intending to
keep the location of the owl a secret as they invariably attract a lot of
photographers which often causes disturbance to the bird when it is hunting but
the location of this bird right by a road means it has not been possible to keep
it a secret so I have instead now very publicly announced where the bird is and
told everyone to keep to the road and behave themselves! Hopefully this will prove
to be the right decision.
I have a lot of images
and video of the owl taken on Tuesday afternoon and from all day on Wednesday.
Even in the gloom before sunrise and after sunset I was able to take perfectly
acceptable photos by bumping the ISO up to 25600. I also had photos taken at
lower ISO that looked pitch black but was able to salvage them in PSE. I do not
bother taking pictures in RAW because of the size of the files and additional
time taken processing them and when you see how much it is possible to recover from
a seemingly ruined JPEG file I feel vindicated in my decision.
Great Grey Owl (lappugle) hunting in the morning
asleep during the day
for a very short period in the afternoon the suns rays hit the bird
none of these images have been edited and show how much the colour of photos can change. All the shots were taken in very quick succession
hunting in the afternoon
I had a few opportunities to take flight shots in the afternoon but had the Beast with me and this was the best I managed. Apparently the bird can be aged as 3cy+ but better pictures are needed to be more specific. It is possible to see that there are two generations of secondary feathers
This picture was taken
with ISO 6400, 1/320s, f 6.3. As can be seen, the original JPEG is almost black but I have managed to lighten it up greatly in PSE. I don’t bother with taking
in RAW and when you can see how much can be recovered from a JPEG then I feel
vindicated
this picture was taken at 15:34 when it really was dark but ISO 25600 does the trick!
