- During 2000,
19 breeding pairs of barn owl were confirmed in
Cheshire at total of 20 breeding sites. Each pair
produced between 0 and 5 young, with the average
number of fledglings being 2.2 (several known
nest sites were inaccessible in 2000 but this
would not sigificantly alter this figure). It has
been calculated that at least three fledglings
per breeding pair are required to maintain stable
barn owl population in Cheshire. The number of
breeding pairs in 2000 appears to have increased
over previous years however this has not been
reflected by an increase in the average number of
fledglings produced per pair, and the increased
record of pairs is more likely to be due to the
increasing network of recorders which is related
to the increased membership of barn owl groups
and increased public awareness.
