Another record
year with nine pairs located at three sites, yielding a minimum
of 18 young. At one site both males and females were heard calling
in February with five pairs successfully raising at least twelve
young. The young birds were only about 300 meters apart (AJ,
JLT et al). At another site three pairs reared at least five
young (JMM) and at a third site there was one calling youngster
in early August (RS). There is undoubtedly more breeding as previous
sites and vast areas of suitable habitat went un-checked. Evidence
of this was seen when a young bird was taken into care from a
previously unknown breeding site in the west of the recording
area (HBC).
Analysis of
pellets from the first site mentioned showed that prey included
89 Field Voles, 12 Wood Mice, four Pygmy Shrews, two Frogs and
a bird. |

Even with
a very half-hearted breeding survey, this year was still the
most successful since BOG was formed. A total of 13 pairs was
found, fledging a minimum of 28 young birds between them.
At the main
site, pairs were noted duet calling in early spring, and this
led to seven pairs breeding, with at least 17 young being located.
One of the young birds was ringed.
At another
regular breeding area two pairs reared three young, whilst
at a site where breeding was noted two years ago, three young
were fledged this year.
A new location,
near a 1997 breeding site, had two pairs with three and one
young respectively, and a further young bird was seen near
another new site.(AJ, PR, SR, RS, JLT et al ). |

This species
continues to maintain its recent and remarkable progress in the
recording area, thanks in no small part to those members who
have enthusiastically encouraged and monitored this (AJ, PRo,
RS, JLT).
In 2005,
a total of eleven pairs were proved to have bred, raising a
minimum of 22 young. It was encouraging that at least two pairs
used the nesting baskets which have been erected at the principal
breeding sites. In summary, successful breeding took place
as follows:
Site 1 : Five pairs raised a minimum of ten young, of which five
were ringed.
Site 2 : Two pairs produced a minimum of three young.
Site 3 : Three pairs, with at least five young, and very probably
more than this.
Site 4 : This is a newly-discovered location, away from the main
breeding areas, and where a pair fledged four young, although
one was later discovered dead.
Near Site
4, and just outside the recording area, a different pair was
thought to have bred, and birds were seen hunting over the
Group area. Similarly, birds were also seen hunting over another
part of the BOG area, servicing another nest just outside it.
Overall, the position is clearly healthy, and other pairs are
probably waiting to be discovered.
There were
no other records, apart from birds calling at one breeding
site in October. |
