Hi all,

We are casual raisers of a few domesticated geese ... Toulouse, Emdens, 
and Africans.

Not counting a number of domestic varieties and hybrids, I'm aware of 
three general "look-a-likes" that include the wild progenitor Swan Goose 
of eastern Asia ... the "Chinese Goose" and the "African Goose" being 
the other two.  Non-breeders of these geese readily confuse the names 
and the geese.  An easy distinguishing feature, I believe, is that the 
wild Swan Goose has a much more prominent and heavier bill than do the 
Chinese Goose and African Goose.  I believe the bill of the Swan Goose 
is always black.  Birds depicted as African and Chinese geese often have 
black bills, whereas others have orange bills.  Maybe someone out there 
knows more about this aspect.

We've raised Africans, who when they breed with our all white Embdens 
yield a color pattern similar to the Africans but with subdued colors.  
When the Africans have bred with our Toulouse (non-dew lap variety) the 
offspring are a simple combination of color traits.  Our African males 
had both the forehead knob and a dew-lap; none of our few cross-breeds 
developed these features.

Does anyone know if the wild Swan Goose male has the forehead knob found 
on male Chinese and African geese?  I've not seen a picture of a male 
wild Swan Goose with the knob.

The pale goose with an orange bill and partial head knob (so probably a 
male) photographed by Maeve Kim at Button Bay on March 17th alongside a 
Canada Goose (perhaps a female) looks to me like a domestic hybrid with 
some Chinese Goose ancestry ... though I'm certainly not an expert on 
all kinds of domestic geese.  I don't have any idea if this goose is the 
same goose seen in the vicinity of the Ruddy Shelduck.  Perhaps there 
are other photos of that "mystery goose" out there.

Perhaps next year's mystery goose will have some traits of Canada Goose 
in it?
