February 2015 - We call him the Owl man!
Regular blog readers will know that 2014 was an incredible season on Langholm moor. A mild winter and incredibly high vole numbers were perhaps the triggers for an excellent breeding season for many raptors including Hen Harriers and Short Eared Owls. The moor welcomed many visitors to perch on the roadside and watch the wonderful views of birds all around; one such visitor became a semi-permanent feature on the roadside. . we called him 'the owl man'.

Langholm Moor Short-eared Owls in 2014
In recent years I have developed an
almost obsessional love for owls, especially Short-eareds. I am now approaching
four years in maybe a seven to eight year period of time writing a book about
those beautiful lemon-yellow eyed creatures. I’m not a life long birder, indeed
I still describe my identification skills for our feathered friends as being OK
for Sparrows and Albatrosses, but still pretty useless for those falling in
between! After I lost my wife a good friend introduced me to birding as a way
of trying to fill a big gap in my life and the first ”unusual” bird we saw was
a Short-eared owl, slowly hopping from post to post in front as we drove an
Isle of Sheppey, (Kent), marsh road at walking pace. An amazing and beautiful
creature about which I soon developed an insatiable desire to find out all I
could. Plenty of scientific papers written on various aspects of their lives,
but no book. So I decided to write one myself, and thus started the long road
that eventually saw me arrive on Langholm Moor on 23rd May last
year.
A road that has already seen me spend
vast amounts of time observing and photographing Short-eared owls, (and any
other owls that came close), as well as driving to many locations around the
British Isles to broaden my knowledge and understanding of them. From South
Wales to the Outer Hebrides, Salisbury Plain to the Orkneys and many other
places in between. I have seen and learned much and received a great deal of
help, (especially on the Orkneys earlier this year), but nothing substantial on
breeding season activity. Until I came to Langholm Moor in 2014.
My first visit to Langholm in May was
thanks to Sonja Ludwig who had responded very quickly to one of many requests I
sent out to various organisations for help with my Shortie breeding season
field work. She told me 2014 was an exceptional year for these owls breeding on
the moor and on arrival I was immediately watching various males hurrying about
feeding their females and the hatched young. As well as vigorously defending
their well defined territories from adjoining males and indeed any bird seen as
a likely threat to their food supply, (primarily voles), and the young owlets.
On just my second day Mac Hotson and
Sonja, (members of the raptor study group), allowed me to accompany them to a
Short-eared owl nest where they were scheduled to ring the owlets.
That nest visit saw the male making his
distraction display as we got close: a variation of the broken wing display
used by a number of other birds. The female stayed on the very rudimentary nest
in amongst some taller grasses, (Shorties are ground nesting owls), until we
were almost upon her, leaving three young owlets to be rung. Two were healthy
sizes and looked in good shape, one was clearly not and the verdict from Mac
and Sonja was that it would not survive long. Close by was a 12 day old owlet
that had already started it’s wandering from the nest. As ground nesting owls
part of their survival strategy is for the young to leave the nest very early
and spread out in the adjoining habitat, thus allowing at least some to survive
if a predator such as a fox finds the nest. That means the adults have to be
good not only at making a number of kills each day to feed them, but also at
finding their wandering young who can be up to 200 metres from the nest as they
grow. That process is helped by the young making lots of food begging hisses
when the adults are flying near, a sound that characterised that part of the
breeding cycle over much of the moor.
From then onwards in what became
numerous trips from Kent to Scotland, I spent a great deal of time on a
moorland road watching a number of breeding territories whilst always making
sure I minimised any disruption to the very friendly local people, the owls,
and I kept well away from the many Hen Harriers breeding there. Visible
activity peaked from mid June to early July as the juvenile owls started to
fly, but were still dependant on the adults for food. Meaning very hard work
for the adults and not very good news for the many voles on the moor. Large
numbers of those latter creatures, (their numbers are cyclical), was the reason
for the good number of Short-eared owls breeding on the moor in 2014. A more
normal level of voles would see only a small number of owls, and they would be
very thinly spread.
June saw the juveniles flying, often
together as a family unit as they emerged in the evenings from their daytime
roosts: all these owls showing a distinct preference for nocturnal activity.
Something not that widely realised by those who only watch their daylight
activities in the winter months on coastal marshes and lowland in other parts
of Britain. All too soon the sights of
several young lined up on fences where they exist on the moor waiting their
first feed of the evening was just a memory as they became well and truly
fledged, fending for themselves.
Then, from late July and continuing
into October, the owls started to disperse from their breeding territories. A
few maybe just across the moor before a final departure, but with the majority
no doubt heading directly South to seek milder over wintering areas in Britain.
With some possibly going much further South than our shores in search of an
area where adverse winter weather does not stop easy access to a reliable food
supply. A very few stayed into November,
becoming hard to find due to their continuing nocturnal behaviour. It will be touch and go if those few stay on
the moor or if any reduction in voles and/or bad weather forces them to leave
too.
My visits have continued as I need to
record the owls’ departures and the empty areas of moor where only a few months
earlier I was so regularly finding these beautiful creatures in good numbers. A
sadness at times seeing the emptiness.
But an understanding and appreciation that all those who work on
Langholm Moor on the project have created an environment with the side effect
of helping swell the British population of Short-eared owls. 2014 has been
exceptional I know due to the large number of voles, but I do hope that 2015
and future years still see at least some of these lovely owls choosing to breed
in such a wonderful and friendly part of Scotland.
