From this website: https://www.beautyof.../swangoose.html

Swan Geese, also known as Chinese Geese, are rare, migratory geese that breed in inland Mongolia, northernmost China, and
southeastern Russia; and most migrate to central and eastern China for the winter. The large Swan Geese have also been introduced to countries outside their natural range, where feral populations of escaped or released domesticated birds have established themselves.

Swan Geese are large, measuring about 81–94 cm in length. They are the longest of all Anser geese). They typically weigh between
2.8–3.5 kg - making this species the second-heaviest Anser goose, second only to the Greylag Goose. The male's wings measures
between 45 - 46 cm and the female's 37.5 - 44 cm. The male's bill is about 87 - 98 mm long and the female's about 75 - 85 mm.

The domestic swan goose sometimes has a white patch behind the bill and typically has a large knob at the base of the bill, which lacks in the wild form.

These shots of some feral geese were taken at a lake in a local Texas park with my Nikon Coolpix P1000.

I think there is an ID error here!

What I see are African Geese, not Asian Swan Geese. See…

Swan goose - Wikipedia

You may have a point. OTOH, according the website I linked in the OP (Swan Geese | Beauty of Birds):

 

"The Swan Geese (Anser cygnoides) -- also known as Chinese Geese - are rare, migratory geese that breed in inland Mongolia, northernmost China, and southeastern Russia; and most migrate to central and eastern China for the winter."

 

"The large Swan Geese have also been introduced to countries outside their natural range, where feral populations of escaped or released domesticated birds have established themselves."

"In the wild form, the heavy bill is completely black; and the legs and feet are orange; and the eyes (irises) are maroon-colored."

 

"The domestic swan goose sometimes has a white patch behind the bill and typically has a large knob at the base of the bill, which lacks in the wild form." (my emphasis)

This seems to correctly describe the critters in my images.

 

The link you've posted describes Chinese Geese (Swan goose - Wikipedia). This is a link to the African Goose: https://en.wikipedia.org/wiki/African_goose

 

JMO, but the images from all three websites seem to show the same geese and all describe a relationship between Swan, Chinese and African geese. It's all a bit confusing.
