GADWALL Anas strepera
Increasingly regular passage migrant and winter visitor

Seen most years in small numbers. Click for pdf file. Recent Sightings:

2007

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.

2010

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.

GARGANEY Anas querquedula
Scarce passage visitor

1993

 

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.

2008

Just one record: a drake at Otley Wetland on 4th May.

2009
A pair was present at Snaygill from at least 24th April to 1st May.
 
2010
A pair spent the day at Leeshaw Reservoir on 22nd April.
RED-CRESTED POCHARD Netta Refina   Scarce vagrant and possible escapee
1992
A female bird at Baildon.
1996

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.
RING-NECKED DUCK Aythya collaris    
 
1995
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.
2001
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.
GREATER SCAUP Aythya marila   Increasingly regular passage/winter visitor
 
Seen each year from 1987 to 2008. Click for pdf file.
 
2010
Only one record: a drake on Warley Moor Reservoir on 10th April.
EIDER Somateria mollissima    
1990
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.

2001

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

 
2008
The first record since 2001, a drake was seen on the River Aire at Bingley on 31st December.
LONG-TAILED DUCK Clangula hyemalis    
 
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.
COMMON SCOTER Melanitta nigra   Scarce, but regular pasage visitor
  Seen most years from 1987 to 2008. Click for pdf file. Recent Sightings:
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.

SMEW Mergellus albellus   Uncommon and irregular winter visitor
  Seen in the following years: 1987 to 1991, 1995 to 1998 and 2000 to 2003. Click for pdf file. Recent Sightings:
2001
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.

RED-BREASTED MERGANSER Mergus serrator
  Scarce passage visitor
  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.

RUDDY DUCK Oxyura jamaicensis   Increasingly uncommon/passage visitor
    Seen in most years 1987 to 2008. Click for pdf file.
 
2009
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).
