Great Snipes lek 2019
And the final post from the long weekend in the
mountains and always a major highlight of my birding year – lekking Great
Snipe. I discovered the lek that I visit back in 2012 and it has had varying
numbers of birds visiting it. In 2012 I reckoned there were as many as 10 males
displaying, 9 in 2013 , 12 in 2014, 6 in 2015, 5-7 in 2016, 3-5 in 2017, 4 in
2018 and this year 4-5 males. So it looks definitely like the numbers are
falling although in the early years I visited the lek later in the season than
I have done since 2017. I have always thought that activity would be higher
early in the season but it is possible that males move around and that this
particular lek attracts more birds at the end of June than the beginning?
The sound from the lek only carries at most a couple
of hundred metres (to the human ear) so it is a wonder that birds find there
way to the leks. Obviously older birds can remember where the lek is but how do
young birds find it? They were born in the area but would never actually have
visited the lek and the nest site is potentially kilometres away from the lek.
There is always some activity to be heard when I walk
up to the lek site around 2230 when the light is still good but this often
stops when I sit down (presumably my presence is noticed). If display does
continue then the birds are usually hidden in the dwarf birches and it is not
until around 2315 (or often later) than the real activity starts with multiple
birds displaying and standing out openly on tussocks of grass. There are often
birds flying and running around and occasional fighting but it is very rare
that I have seen what I believe to be a female visiting the lek. Once it gets
dark (or as dark as it gets at this time of the year) then the birds seem unbothered
by my presence and display within 10 metres of me. When I have visited the lek
site during the day there appear to be no birds present.
I visited on two nights this year and on both there
were definitely 4 males displaying and probably 5. I left at midnight on both occasions
and more birds could potentially have arrived afterwards.
I took a lot of video and pictures using the bazooka
on a tripod. I forgot my torch which I have previously used to (briefly)
illuminate birds so tried using the built in flash with varying success but I
was also impressed with how well the camera coped at high ISO.
I have made 2 videos. The first is very short and shows two display sequences whereas the second is a much longer Director's Cut with far more behavioural sequences including fighting males (after 4 minutes or so).

an attempt at an action shot as it ran over the lek 1/80 sec ISO12800

Look at those legs! Taken with flash at 2337 1/80 sec ISO1600
the white tail feathers which are spread out at the end of the display are SO obvious in the dark
this is the original JPG (I don't bother with taking in RAW) with flash
and this is the result after lightening up the picture.
taken at 23:56 1/80sec ISO25600 - perfectly OK as a record shot
