Fairly
predictably all the records came from lower Wharfedale, and didn’t
involve more than four birds at any site. In January and early
February, up to four were seen at Knotford Nook, and could have
included a bird seen earlier at Otley Wetland, and at a private
site. However, from the pattern of records, one at Lindley Wood
Reservoir mid-month was different. After a gap of seven weeks,
Otley Wetland had a pair on 28th March, and there was a scarce
spring record of a bird there on 7th May. There was then a marked
scarcity of reports for autumn and the later winter months, consisting
only of the same two birds at Otley Wetland and Knotford on 13th
October, one at the second location on 9th November, and two
on 22nd December. |
2008 |
Knotford Nook had the majority
of sightings, with up to six there in the first winter period.
Otherwise, no more than two birds were seen, with sporadic records
from Thornton Moor Reservoir, Otley Wetland and Cononley Ings. |
2009 |
A fairly typical year, with up to
five birds at Knotford Nook in the first three months, and two at
Otley Wetland. The other sightings were both in April: a pair at
the Wetland, and (probably betraying feral origin), a drake standing
with a pair of Mallard on a canalside house roof in Rodley. |

Unusually,
all this year’s
sightings were at Otley Wetland. Numbers were smaller than usual,
and comprised a pair in January and December, and singles on four
days in March and one in April. |

At
last! After waiting six years, three records of this handsome
duck. Otley and Elland Gravel Pits held a pair and a male respectively
on 11th May and a female at Kex Gill Quarry put in appearance
on 23rd September. |
1996 |
A
welcome return to the annual list with at least two birds recorded
this year. The first was a male at Otley Gravel Pits on 7th and
8th April. The second record was of a juvenile bird that was found
at Lindley Wood Reservoir on 24th August; this bird remained here
until 28th, before moving to Beaver Dyke Reservoir, where it was
sighted the following day. More reports were received of a female/immature
at the same site on 21st and 22nd September, with a further sighting
on 8th October; it is possible that these sightings may in fact
have all been the same bird. |
1998 |
Only
one record was received, this being a male bird at Otley Gravel
Pits on 9th May. |
2000 |
Otley
Gravel Pits held a pair of this handsome duck on 26th and 27th
May. |
2004 |
Two males spent a short time
at Knotford Nook on 27th March. |
2006 |
A male which spent a short time at Otley
Wetland on 8th May was seen by only two observers. |

The
second group record was of a female that was found at John o’ Gaunt’s
Reservoir on 5th and 6th October, despite the bird being very
wary, patient observation allowed a detailed description to be
taken. |
1997 |
Two
records were received for this species in 1997: the first was
of a female bird at Marstons Nature Reserve on 20th May, while
the second concerned the ‘hybrid’ bird at Yeadon
Tarn first mentioned in the Group’s 1996 Report, which
was seen again on 29th May. |
1999 |
The hybrid bird was again present at Yeadon Tarn on
30th March and 22nd April. |
2002 |
A drake in eclipse plumage was present at Otley Gravel
Pits on 17th August. This constitutes the first record since 1997
and the fourth in all. The popularity of this species as ornamental
wildfowl means the possibility of it being an escaped bird must be
considered. |
2006 |
Two
birds seen at Otley Wetland on 5th September, and described from
that observation, had probably been present for several days.
Whilst a popular bird in collections, the time of year and the
probability of both being 1st-winter birds enhances their credentials. |
2007 |
A
drake found at Otley Wetland on 9th October remained until the
year-end. Whilst its arrival date is fairly typical
for an overshooting migrant, the escape possibility cannot be
ruled out. |

2008 |
At Otley Wetland, the drake first seen in October, 2007 spoiled
any credentials as a wild bird by remaining in the area until 10th
September, though sightings were discontinuous. |
| |
2009 |
A
drake was on Yeadon Tarn on 8th January. The date is indicative
of an escape rather than a genuine vagrant. |

The
first Group record was of a splendid male at Knotford Nook on 20th
May. The bird disappeared 92 minutes after being located. However,
this was to a large extent alleviated when two birds, probably
first-winter, turned up at Thornton Moor Reservoir on 22nd October
before moving to the nearby Fly Flatts Reservoir, where the stayed
until 6th November. |
|
The
third record for the Group, and the fourth bird, was a drake found
at Otley Gravel Pits on 20th October, and relocated the following
day at Knotford Nook where it was last seen on 23rd. |

A first-year male was seen well
at Dowley Gap Sewage Works on 19th February. |
1992 |
A single female was present at Fly
Flatts Reservoir on 14th November. |
1993 |
A
first-winter male was present at Chelker Reservoir for two days
from 31st October. The following week ‘a cracking’ adult
male was located on the River Aire near Baildon Bridge gave close
views and stayed from at least 8th until 21st November. |
1995 |
A juvenile at Swinsty Reservoir
on the morning of 3rd December could not be relocated later in the
day. |
1996 |
The only record of the year was
of a long-staying female, which was present at Yeadon Tarn from 24th
February until at least 17th November. |
1997 |
Several reports were received from
a number of different observers, of the long-staying female bird
from 1996 which remained at Yeadon Tarn until at least 11th May.
The only other record was also of a female bird, which was seen at
Knotford Nook on 18th May, this could well have been the same bird,
although weather conditions were reported by the observer to have
been suitable for a passage bird. |
1999 |
An adult male bird was present at
Chelker Reservoir between 26th and 29th May. |
2000 |
There
was only one record, but it contained an astonishing number of
birds – 14 at Otley Gravel Pits on 9th May. This is the highest
number to be recorded in The Group’s area, and exceeds the
aggregate total of birds seen previously. |

After
the comparative riches of the previous year, normality was restored,
with just a single bird at Otley Gravel Pits on 21st December. |

The
first record since 2001, a drake was seen on the River Aire at
Bingley on 31st December. |

1988 |
There
was only one spring bird but several autumn records which reflected
good inland numbers elsewhere in the county. There was a female
at Chelker Reservoir from 1st-6th May and in October, a single
at Lindley Wood Reservoir from 11th to at least 24th. November
began with a single at Knotford Nook on 26th with a different bird
at nearby Ogden Pond from 27th-29th on which date another (a third?)
bird was again at Lindley Wood Reservoir. Yet another single arrived
at Ogden’s Pond on 3rd December
remaining until 17th. The last was ay Lindley Wood Reservoir on 27th
December and was considered to be a different individual. Although
it is certain that at least two and probably three, individuals are
involved in the above records, this is not easy to decide, especially
as each bird was ascribed several age/sex characteristics by the
many observers who saw them. The complexity of Long-tailed Duck moult
is obviously little understood. |
1989 |
Many
observations reported lingering birds from 1988 as follows: one
at Lindley Wood Reservoir until at least 2nd February, another
at Ogden’s Pond until 5th February
and a female at Knotford Nook from 22nd February to at least 30th
April. Obviuosly, two, and possibly three, different birds were involved
in these sightings. |
2003 |
A
long staying first-winter female was found at Leeming Reservoir
on 20th November (MS et al). The following day it was seen at Thornton
Moor Reservoir and then at Fly Flatts where it stayed until the
30th November. Meanwhile back at Leeming it reappeared for the
original finder on 3rd December. By the 7th it was back at Fly
Flatts but ended it’s tour back at Thornton
Moor on 19th December. |

2007 |
In a reasonable showing, 11 different
birds were seen, though consisting mainly of one party. April often
turns up passage birds, and a female was at Leeshaw Reservoir from
the 3rd to the 6th, and another at Knotford
Nook on the 5th. Another single was found on Lower Barden
Reservoir on 16th July, and 6th August produced eight birds,
one at Reva Reservoir, and the others, including three drakes,
at Thornton Moor Reservoir. |
2008 |
Almost
all of this year’s
records were of single birds. In March, these appeared on Silsden
Reservoir on the 28th, and Chelker on the 31st, and there
were two records on 28th June: at Leeshaw and Thornton
Moor Reservoirs. On 4th July a bird overflew Oxenhope,
one was on Lower Laithe Reservoir on 31st October, and two at
Cononley Ings on 12th September. |
2009 |
A below average showing, with
only three records. Thornton Moor Reservoir produced three birds
on 22nd June, and 10 on 12th September,
and there were three at nearby Warley Moor Reservoir two days later. |

What
was almost certainly the Lindley Wood Reservoir male of December
2000, was relocated there on 2nd January. There were then records
during Januray to April of ‘red
heads’, which, given the locations, might have involved just
one wintering individual commuting between the reservoirs concerned.
The sightings were: Chelker Reservoir 10th and 19th January, 3rd
March and 10th April and Silsden Reservoir on 9th February. |
2002 |
A red-head found at Knotford
Nook on 28th November was present for three days. |
2003 |
The one and only sighting was
of two on the River Wharfe north of Barden on 11th January. |
2010 |
A
welcome, if brief, return of an increasingly scarce bird in the
area, and not seen since 2003. The bird, (a ‘redhead’)
was found on a tiny patch of unfrozen water at Otley Wetland
on 29th November. Unsurprisingly it didn’t stay. |

In 1987 a pair of Red-breasted Mergansers
attempted to breed in the area. Since then there has only been sporadic
records. Click for more information. |
2005 |
An increasingly uncommon species
in the Group area, there was only one record: a female in the Goosander
roost at Thornton Moor Reservoir on 6th November. |
2006 |
As in 2005, just one record, and
from the same location: a single at Thornton Moor Reservoir on 21st
August. |
2007 |
Two records in the year doubles
some other recent tallies. On 30th April, a bird was seen at close
range near Bolton Abbey, and a pair was present at Ogden
Reservoir from 27th to 29th September. |
2010 |
Two records of this species nowadays
represents a good return. A female was at Yeadon Tarn on 2nd February,
and a pair was seen on the river at Bolton Abbey on 20th October. |

A bird at Otley Wetland on 22nd
April provided the only record. |
| |
2010 |
For fairly obvious reasons, this
species is now much scarcer everywhere, so just one record of a female
at Otley Wetland on 19th August is no real surprise (SJG). |
