THE HOLLINGWORTH GREENLAND WHITE-FRONTS- AN OVERVIEW OF THEIR REMARKABLE SAGA By Simon Hitchen and Ian McKerchar
White-fronted Goose has always maintained a very scarce status in Greater Manchester, with birds generally involving overflying skeins, including odd ones or twos in Pink-footed Geese skeins and 'downed' birds during national influxes of the European A. a. albifrons race. It was with understandable judgment therefore, that when 2 Greenland A. a. flavirostris race birds appeared associating with Canada Geese in the Hollingworth Lake/Akzo Pond area during the winter of late 1991, they were considered to be feral or escaped birds. This was not however, the first record of White-fronted Goose at Hollingworth Lake as there were two previous occurrences of wild birds, both involving large flocks (see below). Their annual appearance as either single birds or a pair, in the Hollingworth area from 1991 until 1998, with the exception of the winter 1993/1994, understandably continued to be treated as feral/escapes by Rochdale recorders and it was not until 28th October 1998 when a bird wearing a neck collar and leg ring (D1H) appeared at Akzo Pond, that alarm bells began to ring and a full reassessment of all White-fronts in the Rochdale area ensued.
Information from A. A. Fox and M. A. Ogilvie revealed that the neck ringed bird D1H, had been first ringed as an adult at Wexford Slobs, Ireland in the early winter of 1993-4 and had subsequently been seen in Islay 1994-5, southern Iceland on 26th April 1996, Wexford again the following winter and then back at the same location in Iceland in April 1997. This lead to the remarkable conclusion that the small numbers of birds present from 1991 were infact truly wild birds and were associating with Canada Geese as their nearest congeners. In the 1997 County Bird Report the appearance of a pair of Greenland White-fronts with 4 juveniles in the Rochdale area in late 1997 were considered to be feral or escapes and was met with the understandable comment "where were they in the summer months and where did they breed?"- well now we knew!
A full account of Greenland White-fronted Goose occurrences in the Hollingworth Lake and Akzo Pond area is listed below, although it is understandably 'patchy' in parts due to lack of recording given their initial status. 1984: 17 flew over on 14th December (which was at time only the fourth county record since 1978), were not assigned to race. 1987: 58 flying south-west on 12th December were not assigned to race, however 2 of which stayed until 14th December, roosting on the lake were of the European race A. a. albifrons. 1991/1992: 2 immatures from November 1991 remained until the early weeks of 1992. 1993: single bird, 2nd January. 1994: a single bird from 27th October 1994 to early 1995 at least. 1995/1996: The single bird from 1994 was seen into early 1995 atleast (certainly until the 23rd January) and 2 birds returned from 15th October 1995 to the year end, although the recording of them apparently being present throughout 1996 is likely an assumption, as data reveals they were only seen during the winter periods at either end of the year. 1997: 2 birds from 1996 present until atleast 6th April. Presumably the same pair reappeared 22nd October accompanied by 4 juveniles and were present until the year end. 1998: 2 birds from 28th October until the year end. 1999: 5 birds present until 25th April. 2000/2001: single 27th November, then flew to Ogden Reservoir where it remained until 7th December, then Hollingworth area until it visited Ogden again on 26th January. Seen several times at the end of March and the beginning of April in the Hollingworth area. 2002/2003: single from 5th November 2002, present until atleast March 8th 2003. 2004/2005: single from 4th November 2004, remained until 27th April 2005.
