2004, ANOTHER GOOD YEAR
First a few statistics:-
- Since the start of the
project,
- Number of boxes where either Barn Owls or Pellets
have been found totals 56.
- Number of boxes used for nesting by
Barn Owls
is 20.
- Young Barn Owls fledged in the last 5 years is
87
2004 has been another great year for RUBOP with
a couple of firsts and though we didn’t reach last years high, this
was our 2nd best year ever.
The firsts were our first successful
use of an interior box and our first ever 2nd broods.
The season started
well with owls nesting earlier
than last year and number of eggs laid was high; however there
was some
bad weather after eggs had hatched which resulted in some infant
mortality and the final fledging figures being lower than last
year.
We had 3 boxes produce 3 fledged young, 5 with
2 and 1 with 1.
Strangely our biggest brood was 5 found in a
tree hole at Owthorpe
Boxes used in the first broods included
boxes used for the 2nd year at Rushcliffe CP, Plumtree, and
Kinoulton, the Hickling
pair which had moved to an adjacent box, a new breeding pair
at Gotham and a pair in a box inside a barn at Colston Bassett. The pairs at Kinoulton, Rushcliffe CP and Colston Bassett all
went on to have small second broods, 2 with 2 young and the other
with a single, all using different boxes but all within their
original territories.
Unfortunately, the single chick died soon after
ringing.
It was disappointing though that for the first
time for 4 years we had no owls breeding at Tollerton though
Barn Owls
were seen
twice in the boxes and the Female that bred at Gamston was killed
on the road in February and the male didn’t find another
mate, however the vacant box did provide us with our first Little
Owl brood.
We also had no returns from the Scarrington,
Aslockton, Flintham areas that had been productive in the past.
A
remarkable ringing return was that the female
that bred in the Hickling box had originated in Cambridgshire
and had been
ringed by the same ringer as that of another Barn Owl found
dead in the same box in February. Both were ringed in 2002 and
had
traveled 70 kms.
Our boxes have also been used for nesting by
Kestrels, Little Owl, Jackdaw and Stock Doves.
Overall, 2004 was
a far better year than 2003,
neighboring barn owl ringers reported great improvements with
one in Lincolnshire
ringing 245 young Barn Owls as against 35 last year.
After a
period of inactivity after the breeding season, the last few
weeks have seen us checking boxes for 2nd
broods, clearing
out old Jackdaw nests and repairing damaged boxes.
Over the
next few weeks, we have 4 new boxes to erect and some more
repairs to carry out.
The intention then
is not to touch any boxes until April/May when owls should
be settled on eggs.
BASF Biocides Ltd have sponsored our 100th Nest
Box.
Situated on a farm close to the Company's Ruddington
Headquarters, the 100th Box was hung on a tree last March, the
box soon attracted
a passing Barn Owl and when inspected in October, a roosting
Barn Owl was found inside, thought to be the male of the pair
that raised 2 broods totalling 4 young in 2 separate boxes
on the nearby Rushcliffe Country Park during 2004
