The vast regimented ranks of plantation forest can seem lifeless for
much of the year; dark and foreboding they stand in silence, with barely the
whisper of a birdcall to stir them from apparent slumber. To some extent this
all changes in summer, as countless Goldcrests and Coal Tits broadcast their
thin, territorial songs from high in the canopy. Later in the summer, there are
even more signs of activity, as small family parties of tits, leaf warblers and
finches move throughout the plantations in search of feeding opportunities.
Such flocks are commonly encountered, mobile though they are, and on occasion
the path of a mixed flock may follow your own; your walk accompanied by a small
chorus of soft tweets, churrs and weeps.
A two-hour walk around the woods at Middle Harling the other morning
brought several encounters of this nature, with the soft flutterings of a
Long-tailed Tit flock the first welcome diversion from the low monotone buzz of
many flies and midges. Later in the walk it was a very different sound that
caught my attention. In a shelterbelt on the edge of an area of clearfell I
chanced across a young Long-eared Owl, potentially taking its first wing-beats
towards full independence. While it may have left the nest several weeks ago it
could still have been dependent upon its parents for much of its small mammal
or small bird diet.
Throughout the various stages of their lives Long-eared Owls make some
of my favourite sounds. As nestlings they make a short ‘pssee’ call which,
although not much to write home about when uttered by a single chick, has a
wonderful jingling quality (like jingling small coins in your pocket) when
several chicks call together. Then, later in life, there is the food begging
call of older youngsters, notably those that have left the nest. This is best
described by thinking of the sound made by an un-oiled hinge. It was this call
that first alerted me to the bird, difficult to see well as it sat in thick
cover.
It has been a couple of years since I last saw a young Long-eared Owl so
it is good to know that pairs are still breeding in the forest. The Long-eared
Owl is one of those species about which we know surprisingly little, largely
because they are widely but thinly distributed, fairly secretive in habits and
predominantly nocturnal in activity. The most recent estimate suggests that
there are somewhere between 600 and 2,000 pairs in England, breeding in
coniferous plantations, mature hedgerows and shelterbelts. Numbers are known to
fluctuate from year to year because of variations in prey availability and may
be swelled in winter by the arrival of migrants from further north.
