We are just pulling together all of the Barn Owl Project data for the 2014 breeding season and there is going to be quite a bit of press coverage due to the fact that it has been an extremely good breeding season and a chick that I ringed last year has been found as a breeding adult female in Leicestershire. All of the information is below and Steve Piotrowski and I had the opportunity to go out live on The BBC Radio Suffolk breakfast show this morning. To listen click here and go to 1 hour 25 mins.
2013’s poor
breeding season
Following a disastrous year for barn owls in 2013, nest
boxes this year have been bursting at the seams with chicks! In spring 2013, barn owls struggled to cope
with a relentless icy blast that decimated the number of short tailed voles
their preferred prey, so barn owls were literally starving to death. Mortality was then extremely high and reports
of dead barn owls were reaching the British Trust for Ornithology (BTO) of up
to 19 per day. These figures involved
only ringed birds, so we were seeing just the tip of the iceberg with a
significant proportion of the UK’s population perishing.
The
project's longest recorded movement so far...

Suffolk's furthest Travelling barn Owl on the Right

Since 2006, the Suffolk Community Barn Owl Project has been
responsible for monitoring specially-designed nest boxes and, by 2014, the number
of boxes installed had reached 1700. The
2013 severe weather resulted in only 261 boxes being occupied by barn owls and
only 66 producing any chicks at all! Most female barn owls failed to gain
sufficient weight (340 grammes) to be in good enough condition to breed, so
decided to skip a year. However, from
one of these boxes came a remarkable movement from Lea Farm, Great Ashfield,
near Stowmarket, to Muston in North Leicestershire, a total of 136 Km. Project Area Coordinator and local farmer, Patrick
Barker, ringed a brood of two chicks at the farm on 7th August 2013
and one of these (a female) was found incubating a clutch of eggs in a box in
North Leicestershire this summer. She
raised three chicks in her newly adopted county. Jim
Lennon, of South Notts Ringing Group (who monitor boxes in North
Leicestershire), said “This was the first
time in five years that the box has been used; we had several instances of
this. The female was not moulting when caught, and we checked for a second
breeding attempt which did not happen in that box, but chicks seem to have got
away okay.” Lea Farm, Great Ashfield is farmed by J. Miles and Sons and is a good example of careful grassland management. Farm Worker, Paul Batchelor, is commitment to conservation on their farms and has created feeding and nesting opportunities for barn owls.

Barn owl chicks are forced out from their nuptial home in
early autumn and they have to find partners and then set up territories of
their own. However, they tend not to move
far, normally no further than six kilometres and often following the course of
a river valley, so this movement is quite remarkable. Along with Suffolk, North Leicestershire and
South Nottinghamshire are barn owl hotspots, so it’s conceivable that our
Suffolk barn owl wandered off in a north-westerly direction until she found
good feeding habitat vacated by barn owls that had succumbed to the severe
weather?
Barn Owls
bounce back
Nature is remarkable in that it often stages dramatic
recoveries and this year our barn owls have demonstrated their resilience to
the extremes of our weather. Provisional
figures for 2014 show that all records have been broken with 516 boxes being
occupied by barn owls! Of these 454 were
found with eggs and 415 went on to produce chicks. This total exceeds the county total of 350
breeding pairs recorded in 1938 and 444 occupied boxes in 2012. The number of chicks in each brood was also
at the highest since the project began with broods of seven being noted in many
parishes. In total, 862 chicks were
ringed from over 1000 that were reared and, in addition, of the 56 adult barn
owls handled, 34 were already carrying rings.
What do barn
owls need?
To sustain good barn owl numbers there must be enough prey. Short tailed voles need a particular type of
habitat - rough, tussocky grass that they can move through in tunnels and that
provides their own source of food and nesting habitat. This habitat, in close
proximity to correctly positioned barn owl nest boxes, provides the ideal
conditions for the owls to hunt.
Currently, much of the county’s grassland is ‘managed’ by
too much grazing or frequent cutting. The project is committed to offer advice
to provide the grassland that barn owls favour across the county – with the
benefits extending well beyond barn owls and voles. This habitat is scarce and
precious, it holds up entire ecosystems from diverse flora to many species of
invertebrates that use it for overwintering.
Suffolk
Community Barn Owl Project (SCBOP)
SCBOP is dedicated to the conservation of barn owls. The principal partners are Suffolk Wildlife
Trust, Suffolk Ornithologists Group and BTO, but a number of smaller
independent projects also fall under the SCBOP umbrella including those
administered by Dedham AONB, Stour Valley Project, Thornham Owl Project and
Suffolk Owl Sanctuary.
The project as a whole has advised on the fixing of 1700
barn owl nest boxes across Suffolk, on nature reserves, farmland and on
community spaces like village greens and school grounds. By providing a connected network of good
habitat and nesting opportunities we can give the barn owls the fighting chance
they need to thrive. The project involves
the whole community and the boxes are made by local organisations and monitored
by an army of expert volunteers each year.
The results are collated by the project recorder, Alec Hillier, who
meticulously records and analyses the data for each box and provide an annual
report. This system of raising
awareness, creating nesting opportunities and managing suitable nearby habitat
is having a positive effect on barn owl populations across Suffolk. This is a project that all Suffolk people can
be truly proud of.
In 2015, SCBOP will be 10 years old and there are plans to
celebrate its success by holding a series of special events. These will include a lecture tour by Project
Manager, Steve Piotrowski, which will start at the Fisher Theatre, Bungay, on 21st
January for Waveney River Trust. The
tour will take in a number of venues throughout Suffolk and finish at the
Rutland Water Bird Fair on August 21st. There
will be an all-day workshop for barn owl enthusiasts at SWT’s Lackford Nature Reserve
Centre on July 11th (please contact Leslie Walduck of SWT, Brooke
House, Ashbocking, for further details) and celebrations will culminate in a
fund-raising party at The Cut, Halesworth, with the audience being treated to a
special lecture by Dr Colin Shawyer, UK’s leading authority on barn owl
conservation and author of The Barn Owl, published by Arlequin Press in 1998.
Finally, some of the barn owl nest boxes are quite old and are
showing signs of weathering. To ensure
that our barn owls keep their homes, Waveney Bird Club has set up a fund to help
pay for repairs and in some cases replace dilapidated boxes. Those
wishing to contribute should make cheques payable to Waveney Bird Club
and send to: Steve Piotrowski, 96
