Notes on Taxonomy and Nomenclature
Top of pageThe split is observed here. As far as possible, this account refers only to the species hutchinsii, although much of the literature from which it is drawn treats canadensis and hutchinsii together under canadensis.
Description
Top of pageB. hutchinsii are very similar to B. canadensis races in plumage pattern but occupy the small and dark end of the range of variation. Like that species they have a dark brown body, a black head and neck and a white chin-patch. Many B. hutchinsii have a white mark or line between the black neck and the brown breast, as do some B. canadensis. The bill of B. hutchinsii is proportionately shorter than that of B. canadensis, as is the neck. Calls are higher-pitched and the race minima in particular sounds ‘cackling’. For further details, see for example Sibley (2004).
Distribution
Top of pageThere is no systematic information on where B. hutchinsii are held in captivity. Partly in consequence, information is likely to be poor also on where isolated escapes or releases have occurred. Since the split from B. canadensis is so recent, it is likely that occurrences of B. hutchinsii are not yet being fully reported.
Distribution Table
Top of pageThe distribution in this summary table is based on all the information available. When several references are cited, they may give conflicting information on the status. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report.

History of Introduction and Spread
Top of pageA number of Canada goose races are likely to have been introduced to the UK and elsewhere in Europe, where they have intermixed freely. During the 1980s it is reported that 40 small-race birds were released in Britain (Blair et al., 2000), presumably attributable to the presently defined B. hutchinsii.

UK | Escape from confinement or garden escape (pathway cause) | No | Blair et al. (2000) | Some occurences are probably of vagrants from native range |
Risk of Introduction
Top of pageThe risk of introduction of this species is unclear. In areas where B. canadensis is already present, it is perhaps likely that mixed pairing would occur with that species. This would be a conservation issue in areas where B. hutchinsii would interbreed with native B. canadensis.
Habitat
Top of pageWhereas flocks of B. canadensis may damage plants by overgrazing or trampling, it is perhaps less likely that B. hutchinsii, being smaller, less abundant and more tied to natural habitats, would cause significant damage

Biology and Ecology
Top of pageThe wide variability in size and plumage within the Canada/cackling species group is likely to have some genetic basis as well as environmental causes, but it is insufficient to prevent the remixing of the races where they are brought into contact by translocations and introductions.

Economic Impact
Top of pageWhereas B. canadensis can have severe economic impacts through air strikes and agricultural damage, the smaller and less numerous B. hutchinsii is likely to have much lower impacts in these areas.
Environmental Impact
Top of pageImpact on Biodiversity
Introduced B. hutchinsii interbreed readily with other races of their own species and with B. canadensis, and so could have significant impact on biodiversity when introduced within the native ranges of these species in North America.
Social Impact
Top of pageIt is possible that B. hutchinsii may have some social impact through fouling or disease transmission, but no such impacts have yet been clearly identified.
Risk and Impact Factors
Top of page- Has a broad native range
- Abundant in its native range
- Highly adaptable to different environments
- Tolerates, or benefits from, cultivation, browsing pressure, mutilation, fire etc
- Highly mobile locally
- Long lived
- Has high reproductive potential
- Gregarious
- Has high genetic variability
- Negatively impacts agriculture
- Hybridization
- Highly likely to be transported internationally deliberately
- Highly likely to be transported internationally illegally
- Difficult to identify/detect in the field
Uses
Top of pageB. hutchinsii is hunted along its migration flyways and in its wintering grounds in North America.
Uses List
Top of pageEnvironmental
- Amenity
General
- Sport (hunting, shooting, fishing, racing)
Human food and beverage
- Meat/fat/offal/blood/bone (whole, cut, fresh, frozen, canned, cured, processed or smoked)
- Oil/fat
Similarities to Other Species/Conditions
Top of pageDistinguishing B. canadensis from B. hutchinsii and potential hybrids with that species is complex and difficult, given the wide range of variation in the size and plumage tones of both species (Wilson, 2003; Sibley, 2004).
Prevention and Control
Top of pageDue to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.
SPS measures
Most European countries and North American states and provinces have laws intended to control trade in non-native species and the circumstances in which they can be released. These should cover non-native geese, but may either exclude translocations within a country or trading zone, or be difficult or impossible to enforce where no import/export controls apply.
There is clearly a need for increasing public awareness of the dangers of introducing non-native geese to new areas and of translocating them within areas where they already occur.
Gaps in Knowledge/Research Needs
Top of pageFurther and more detailed information is needed on the impacts of B. hutchinsii, to strengthen the case for control measures and to discourage further introductions and translocations.
