A dark-phase bird flew down the
valley at Elland Gravel Pits on 8th June, veering off to the north
when mobbed by two Lesser Black-backed Gulls. |
| |
1993 |
An excellent year with two records
coinciding with large numbers reported nationally. A single at
Stockbridge Reserve on 29th August was followed by another in Wharfedale
on 6th September. Good views were obtained and both birds were
well described. |
| |
1996 |
A
bird flying west over Cullingworth fields on the morning of 9th
July was an excellent find, and provided the fourth record for
the Group. |
| |
1999 |
A juvenile was seen and photographed
at Nan Scar above Leeming Reservoir on 22nd September. The bird
was being mobbed by Carrion Crows, and perched in a tree briefly
before flying off south-westwards over White Moor. |

2000 |
The unprecedented influx of Honey
Buzzards into Britain in September and October was reflectedly
locally in the five records submitted for that period. Initially,
two birds were seen on Ilkley Moor on 26th September, followed
by one over Halifax on 30th. On 1st October one was reported over
Denholme Clough, and what was probably the same bird over Thornton
Moor Reservoir. A further bird was seen at Beaverdyke Reservoir
on 8th October, and the final bird flew south over Kex Gill the
following day.
In addition, a bird which could have been this species, but not
specifically identified, flew north-west over Mount Tabor on 6th
October, and a report of a further bird at Thornton Moor Reservoir
was not supported by a description. |

A
mobbing Carrion Crow drew attention to an all dark (female/juvenile)
which flew north-east over Sandwith Moor, Norwood, on 31st July. |
1992 |
A cream-coloured bird was in Wharfedale on 15th August.
This bird was thought to have been in the area for some time. |
1993 |
Two adult females were observed going to roost in
juncos reed at Pickles Gill on 23rd May. |
1994 |
This was
the best year so far, coinciding with a large influx. All records
relate to passage ‘cream crowns’.
The first flew north-west over Thornton Moor Reservoir on 22nd April.
The following day a first-summer bird passed south-west over Timble
Ings Plantation. On 3rd May one at Round Hill was a bonus for observers
twitching a Dotterel. Next day singles were seen at Thornton Moor
Reservoir and Oxenhope Edge. |

A ‘cream-crown’ bird
was seen firstly at Kex Gill and then at Thruscross on 30th August.
Presumably the same bird was recorded again at Kex Gill the following
day. |
| |
1997 |
A better
than average year, with three records of single birds, all during
the spring. Late April to early May is prime time for passage Marsh
Harrier, and so the first sighting, on 27th April on Barden Moor,
was right on cue; this bird, an adult female, hunted the moor for
a while before it eventually soared up high and crossed the River
Wharfe to the Barden Fell area where it disappeared, heading eastwards.
Only three days later, the first male bird ever recorded in the
Group’s area – a splendid adult – was
soon flying north-west over Morton Moor, pursued by a mobbing Curlew.
The year’s final record concerned a ‘cream-crown’ bird
(presumed to be a female) which was seen near the Ovenden Moor wind
farm on 22nd May |
| 1998 |
There was
just two records during 1998, both single ‘cream-crown’ birds – each
in spring and autumn. The first of these was seen over Morton Moor
for about 30 minutes on the morning of 23rd April, it was accompanied
by up to four Short-eared Owls before disappearing north-westwards
in the direction of High Moor. The second sighting was of a bird
which flew west across the Wharfe valley at Barden Scale on the evening
of 29th August. It reappeared later, quatering the moorlands further
west, where it, too, associated with a Short-eared Owl for several
minutes. The Marsh Harrier was last seen flying low over Barden Moor,
carrying prey, at 8 pm, and no doubt roosting in the vicinity. Detailed
views of the bird’s plumage were not possible, but the complete
absence of any sign of wing-moult indicated a juvenile bird. |
| 1999 |
There
were four records, all of ‘cream-crowns’.
The first was a female seen from Barden Scale in Wharfedale on
16th May, but the bird was not picked up until it was stooped on
by a Common Buzzard over the Hare Head moorlands. After several
minutes of interplay between the two raptors, the harrier drifted
over Barden Moor and disappeared to the west. Only a few days later,
on 20th May, an observer searching for Dotterel in the vicinity
of the Twelve Apostles stone circle on top of Ilkley Moor reported
a bird flying north-west, mobbed at one stage by a Curlew.
Next
came the first mid-summer record since 1991, when a single bird
was seen hunting at Thornton Moor Reservoir on 29th July. Finally,
a juvenile – aged on its full complement of wing
and tail feathers – was watched from Barden Scale on 25th
September, the latest date for the species so far. This bird quartered
the fell top on the opposite side of the river before crossing
the valley to Barden Moor and vanishing westwards. |
| 2000 |
There was five records, all of single birds and
all from the Barden Scale area. The first sighting came from there
on 23rd April, where what was considered a yong male bird was seen.
What was almost certainly the same bird was present there the following
day. The next records came over a period of some three months,
with birds seen on 22nd May, 11th August and 29th August. Birds
recorded from Barden on different dates (but without descriptions)
could have referred to those mentioned above. Two other records,
including one at Timble Ings, were also undescribed. |
| 2001 |
Another
good year, with five verified sightings, all of which related
to spring and autumn passage, and all were of ‘cream crown’ birds.
The first was seen on Hanging Moor, Blubberhouses on 23rd April,
followed by another relatively nearby on Kex Gill Moor on 30th
May. The remaining sightings were in August, with singles at
Barden Scale on 10th and at Kex Gill on 16th and 28th. |
| 2002 |
There were seven records, representing at least
eight birds. In the spring, a male was seen at Timble Ings on 19th
April, with a cream-crown at Barden on 26th May. Autumn passage
commenced with a juvenile at Timble INgs on 16th August, and an
excellent period around the month end produced three birds at Barden
Scale on 31st, with singles also there on 1st and 2nd September.
The final record was also at Barden, on 18th September. |
| 2003 |
First up
was BOG’s earliest ever record with
a female flying through Barden on 22nd March with probably the same
bird flying east at Sandwith Moor later that day. Following that
another early record was of a single at Barden on 3rd April. A male
was noted flying north-west at Blubberhouses on 16th April. The next
record was of one at Barden on 15th May with an adult female there
on 11th, 20th, 22nd and 29th June. This site also yielded a single
bird on 21st July and almost daily sightings between 14th and 29th
August. The only records away from Barden were singles at Dob Park
on 27th August and at Kex Gill on 4th September. |
| 2004 |
A very poor showing this year, with only two authenticated
records: one at Thornton Moor Reservoir on 19th April and
another seen from the Barden watchpoint on 20th May. |
| 2005 |
Whilst an average year, it was a distinct improvement
on 2004, with seven records, all single birds, and coming mainly
from Barden Scale watch-point. This site had the only spring records,
on 21st April and 1st May, and autumn passage produced birds there
22nd July, 21st August and 12th September. Nearby at Langbar, a
hasty exit from his car enabled the observer to get good views
of a cream-crown bird which flew across the road in front of him
on 30th August. A rare record came from the south of the area,
with a bird moving east at Thornton Moor Reservoir on 31st August. |
| 2006 |
The
six accepted records this year are in line with 2005, and it
is notable that half of them came from the south of the area.
All the birds were ‘cream-crowns’, indicating
either females or sub-adults, some of which were specifically designated
by the observer.
Warley
Moor Reservoir had the first of these, on 25th March, a probable
juvenile, and another was seen here on 15th July. Of Barden Scale’s two reports, on 7th June and
25th August, the second was a juvenile, but the year’s
final birds, both on 9th September, couldn’t be aged. These
were seen at the opposite ends of the recording area, at Leeshaw
Reservoir, and Sandwith Moor. |
| 2007 |
Only three reports represent a rather poor return
these days, and it is particularly surprising that only one originated
from Barden Scale, a juvenile bird seen on 29th August. The two
other records were probably also of juveniles, and were from Oxenhope
on 6th September, and Denholme Clough on the 16th. |
2008 |
A much better year, with six reports, four of which
came from Barden Scale, where singles were seen on 4th June, 7th
and 23rd August, and 10th September. Elsewhere, birds
were noted at Draughton Heights on 25th July, and Leeshaw Reservoir
on 8th August. |
| |
2009 |
A
less than average year, with five reports of single birds, mainly
from Barden Scale, where there were sightings on 31st July, 10th
and 19th August, and 9th September. The first of these was a ‘cream
crown’ bird,
and the others juveniles. The other report came from
Norwood Edge on 14th September. |

In the first winter period up to two ringtails were
seen fairly regularly sometimes four, with possibly five ringtails
coming into roost on 19th February. In addition to this, records
of second winter males came from two sites a considerable distance
apart between 4th March to 13th May but possibly still related to
the same bird.
A passage male was seen at Thornton Moor reservoir on 28th April.
A first summer male was observed at a moorland site between 25th
May and 21st June and although skydancing was seen and two birds
were present on 16th June there was no suggestion that breeding took
place. At another site an adult male was observed hunting in the
evening of the 31st May before finally going to roost.
In the second winter period a minimum of two ringtails and a grey
male were present on the northern moorlands. In the south of the
area single ringtails were observed at Soil Hill on 10th November,
Fly Flatts reservoir on 30th November and Leeshaw Reservoir on 21st
December and could possibly relate to the same individual. |
|
During January a small but regular roost was discovered
near to the one being used in 2002. At least four ringtails, two
adult males and a second-winter male were observed in total, although
between three and five birds were normally noted on any given evening.
Probably one of the same adult males was observed intermittently
roosting at another site a few kilometres away. Elsewhere, the
usual moorland records were obtained, typically of ones and twos,
with birds on passage seen in April and October.
As usual, things went quiet during the breeding season, but a bird
seen in Wharfedale in July had been tagged in a nest in Bowland,
Lancashire, a few weeks previously.
During the second winter period, the two previously mentioned
roost sites held a ringtail and an adult male respectively, while
up to five hunting birds were recorded in Wharfedale in November.
Only single ringtails were observed in December. |

Whilst an average year, it was a distinct improvement
on 2004, with seven records, all single birds, and coming mainly
from Barden Scale watch-point.
This site had the only spring records, on 21st April and 1st May,
and autumn passage produced birds there 22nd July, 21st August
and 12th September. Nearby at Langbar, a hasty exit from his car
enabled the observer to get good views of a cream-crown bird which
flew across the road in front of him on 30th August. A rare record
came from the south of the area, with a bird moving east at Thornton
Moor Reservoir on 31st August |
|
The
total of only 17 records received for this attractive raptor
represents the lowest since 1991, and it is likely that no more
than 13 different birds were involved, itself a low figure compared
to many previous years. The situation is therefore quite concerning,
particularly as the answer doesn’t lie
in under-recording: indeed the main locations for the species are
now considerably better watched than they were 15 years ago. This
may be a temporary lull, but the position needs to be monitored.
There is a suspicion that birds are now wintering in only very
small numbers, if at all. Only three birds were seen in the first
three months: a juvenile at Barden Scale on 11th and 12th January,
a ring-tail there on 19th March, and an adult male at Whetstone
Gate ten days later, which fortuitously and obligingly flushed
two Short-eared Owls for the observer. The third Barden Scale record
illustrated the changing scene there as the bird was pursued by
a Red Kite. The second winter period was totally devoid of records,
and the remaining ones probably all relate to birds relocating.
In April, a bird was seen at Timble Ings on the 14th, and another
on the moors near Oxenhope on the 16th, one of only three records
from the south of the area. May produced a male at Barden Scale
on the 16th, and records of what was presumably the same ring-tail
bird on the moors adjoining Leeshaw Reservoir on the 29th and 30th.
The lack of midsummer records was unsurprising, but there were
only two for the early autumn period, a bird at Barden on 22nd
August, which attracted the attentions of a Peregrine and a Kestrel,
and a bird on Sandwith Moor on 9th September.
All the remaining records originated in October. A different bird
was seen on Sandwith Moor on the 8th., and there were two reports
on the 13th., of single birds at Kex Gill and Whetstone Gate. Ten
days later a ring-tail was seen at Noska Brow and South Nab, and
the following day one was over Barden Fell, the first sighting
at the usually productive Barden Scale site for over two months.
Given the proximity of these three locations, it is likely only
one bird was involved.
Two
of the sightings involved wing-tagged birds. The tag colours
on the August bird couldn’t be made out, but the detail
seen on the Sandwith Moor bird of early October identified it
as having been fledged that year in Bowland. |
2007 |
The
rather disquieting situation set out in the 2006 Report remains,
and has actually worsened, as just eight records were received.
Only the Group’s inception year of 1987 had
fewer, and it will be noted five of the reports cover an eight
day period. The dates involved confirm it is unlikely birds are
now wintering in the area, and are suggestive of passage.
In the early months, singles were seen at Barden Scale on 6th
February and 12th March, and at Blubberhouses on 2nd March. As
indicated, all the remaining records covered just over a week,
and came from Barden in November. Up to two birds were seen on
the 2nd, 3rd and 4th, and three on the 6th, probably including
one of the birds seen earlier. Three days later, two birds were
seen, including at least one of those seen on the 6th. It is thus
possible only seven birds were observed in the entire year.
Tags carried by one of the November birds indicated it had been
raised during 2007 in Bowland. |
2008 |
After a couple of lean years, there was a welcome
upturn in both the numbers of records and birds seen, which the
pattern of sightings suggests was a minimum of 21 individuals.
As usual, most of the reports came from Barden Scale, where birds
were noted in all but May, June and July, and usually involved
single ringtails, though two were seen in October and December.
Other singles were seen on Hazlewood, Denton and Sandwith Moors,
at Whetstone Gate and on Addingham High Moor (where an adult male
was found on 1st September), and there were birds near Timble Ings
in October.
In addition to these records, a displaying male was seen in early
May, but quickly departed after failing to attract a mate |
| |
2009 |
With only
six records of the same number of birds, last year’s upturn
has proved short-lived. Apart from a sighting at Timble Ings, all
the reports were from Barden Scale which had records between January
and June. Clearly, a once fairly common bird is now anything but. |

several minutes on 9th July from the Barden Scale watchpoint, the

brief, the detailed description enabled the record to be accepted
by the YNU |

Numbers seem to be dwindling to
a perilously low level and one can only assume that this is due to
suspicious circumstances. In fact this species has become so uncommon
in the area that it has been placed back on the rarity description
list.
At one location a single bird was regularly seen “sitting out” between
January and 7th April while another location provided a handful of
records during March.
At a third site, which used to be reliable for this species, only
a single bird was reported on the evenings of the 23rd and 26th May.
On the latter date the bird made a brief pass at a Long Eared Owl.
Elsewhere one bird was observed at a fourth site on a BOG coordinated
raptor watch on 22nd March and a single seen soaring between two
of the above sites on 13th April. |
| |
2004 |
Once
again, notable by its absence for most of the year, although
this was the best year for a while as regards displaying birds
in spring. The regular sitting-out bird was visible from January
to April at one site but was more erratic than in some years,
with only brief display noted.A few miles away at another regular
site a few records were received, including a pair on one day
and a female being mobbed by two Carrion Crows two days later.
A third site provided a record of a pair displaying and, on another
occasion, a single being harried by a Peregrine. In a fourth
general area, a handful of records included females and pairs
together. Only one report, of a male, came from the south of
the area.
In line with previous years, there was no indication of breeding
despite regular coverage, and the masses of suitable habitat and
vast abundance of prey available. One can only assume that persecution
and possibly disturbance are playing a part in suppressing the
local population. |
| |
2005 |
Once again the sightings (or
lack of them) for this species are as frustrating as ever. There
were only eight records from five relatively proximate sites, and
a co-ordinated watch of these and others in March produced a co-ordinated
nil return. Yet again, there was no evidence of attempted breeding,
and it is tempting to suppose the area contains no more than a
handful (if that) of mobile birds.
At the first site, what was presumably the male seen in previous
years, was observed sitting out on two occasions in spring, but
with little display activity. Another bird, possibly a female,
perched out at a second nearby location on two consecutive days
in March.
In
a third general area, single males were seen on three days (at
different sites) and two on another day at one of them. There
were no sightings after 3rd April. |
| |
2006 |
This
year’s records tend
to indicate that the species continues to maintain its presence
in the area, if only just, and there is still no indication of
breeding activity, despite some display and the intermittent presence
of an apparent pair.
Two
principal locations were involved. At the first, a male was seen
on 28th January, and a sub-adult female on 31st March, but
neither observation indicated more than a transient presence
in the area.
The
other location has produced birds perched out prominently in
the early months in previous years, and this year the first such
male was seen on 16th February, with what was probably a different
bird there on the 27th. This second bird was then seen on several
more dates to 4th April, and was in the company of a probable
female on the 1st and 3rd of that month, the female having also
been seen individually a month earlier. The final authenticated
record was of a male in the same general area on 24th June
but two other reports weren’t supported by
a description. |
| |
2007 |
As in other recent years, most
of the records came from two main areas, and probably involved
three different birds. Another two birds were seen elsewhere. Once
again, there was no suggestion of breeding, nor of paired birds,
though display was seen at one of the locations.
An
adult was noted perched out prominently at a regular site on
27th January, and there were further sightings here, including
territorial display, during the next two months. At the
other regular locality for this species, the month of March produced
records of a 1st-winter female on the 12th and 13th, and
a 1st-winter male on the 7th, with possibly the same bird
being seen again on 12th April.
A few miles distant from the first location, an adult female was
observed at close range on 21st March (RHP), and there was a rare
Airedale record of another adult female, apparently relocating,
on the previous day |
| |
2008 |
At
one regular site, the probable resident male was first seen on
28th January and on several other dates in early spring, and there
was a different bird there on 3rd April. There was also
a scarce autumn report from this location on 13th October.
Elsewhere in spring, a 1st-winter male was seen on 3rd March (AGG).
Two other records clearly referred to birds on passage: at Thornton
on 10th April, and Thornton Moor Reservoir on 21st September. |
| |
2009 |
The
presumed regular male was seen at its usual site on three dates
between 1st and 22nd March, during which period a female
was also seen, on the 18th. At another regular location, a female
was observed between 29th and 31st March, accompanied on the last
date by no less than three males. Despite this, there was no indication
of breeding activity, and no sightings of any sort in the area
after the end of March, A female seen in Airedale on
30th March was clearly a different bird. |

Our area benefited from the large
influx of this species into Britain in late October. The moorlands
held probably three birds, possibly more, and provided some of
the best bird-watching this area has seen. Many bird watchers came
from outside the are and as a result some locally rare species
were reported. All records relate to immatures and indeed this
was the trend nationally.
The
first arrival was at March Ghyll on 23rd October where a bird
spent the whole afternoon hunting persistent hovering taking
place. The following day two birds gave good views at the same
date. A single was recorded here the following day. One of the ‘March
Ghyll birds’ was thought to have moved to nearby Timble on
28th October where views down to 20m were obtained by one observer.
One was also reported in Wharfedale on the same date. The Timble
bird remained in a small open area at Ellercarr all the next day
and at least all morning on 30th October. Also on this latter date
at nearby Beamsley Moor two birds were observed for over an hour,
one being mobbed by a Common Buzzard. Up to two birds were reported
around Timble and Round Hill until 6th November. Sightings after
this date until the year-end were patchy and involved just single
birds. The remaining records were: Timble 11th and 19th November,
Kex Gill 13th November, March Ghyll 20th and 21st November and
11th December, and Wharfedale between 16th and 20th December. |
1995 |
Following
the influx in Autumn 1994, single immatures were reported on seven
dates in the first three months. It is unclear whether all sightings
involved one individual. After being seen in Wharfedale on New
Year’s Day there were
no reports until 4th and 5th February when one was in the Timble
area. The remaining records came from Wharfedale on 12th, 14th and
23rd February and 19th March. |
1996 |
Rough-legged Buzzard was recorded
for the third successive year. A juvenile frequenting the Wharfedale
area was seen on 1st December, and again on 8th December. |
1998 |
The
year’s only sighting
was of a bird which was well seen flying low over Barden Fell on
5th March. It was believed to be a first-winter bird, taking into
consideration the amount of black on the belly and the very pale
patches on the upper wings. |
| 2001 |
It was a welcome, if brief, return
of a species not seen in the recording area since 1998. A juvenile
bird provided the sole observer with excellent views on Denton
Moor on 15th November. |

On 14th February, a very large raptor
was seen gliding away in the distance near Bolton Abbey, Wharfedale.
It seems likely that this bird was the Golden Eagle which had been
frequenting the area around Gouthwaite Reservoir in Nidderdale (about
nine miles to the north-east) during much of the winter. However,
distance and viewing-angle precluded a firm claim. |
