The sightings and occasional thoughts of an English birder in Oslo

Adders from April 2019
In addition to the the Three-toed Woodpeckers I had
also promised a blog post on Adders from last spring but have only just realised
I had never got around to doing so with the reason being that I had taken far
too much video and stills from that day and kept putting off going through them
until I finally forgot about them...
I have now gone through them though and
have some quite satisfying pictures of males fighting. I also filmed what I
thought was mating but my videos only seem to show a male earnestly trying to
mate but a female who was not yet opening up to his advances. I have put together
a video though which while being quite long shows some interesting behaviour
and was fun to make.
Add caption
the female was very distinctive
as was the Black (male) Adder
but the blue/grey males could also be told apart due to their head markings especially between the nostrils. Male #1
