- The source says
Today's Suffolk derives its meatiness and quality wool from the old original British Southdown ... sheepmen of that day did not like the long legs, flat sides, nor wild nature of the Norfolk Horned.

- The page saysDomestic sheep now live worldwide alongside people
- The source says
Domestic sheep live worldwide in association with humans
Note: species-wide, and worded as all domestic sheep, not the breed - The page saysMainly grasses at pasture; can also be fed a wide variety of hays and oats
- The source says
sheep feed mainly on grasses while in pastures and can be fed a wide variety of hays and oats
Note: species-wide diet; no breed-specific diet source - The page saysNot Evaluated

IUCN Red List No special status

- The source says
Ovis aries has a highly developed flocking or herding instinct

- The source says
Large groups of sheep (up to 1000 or more) move over an area in groups, rather than as individuals. No "leaders" in the flock initiating grazing or other forms of behavior, including flight
Note: 'running away' for 'flight' - The page saysThat instinct is part of their value to farmers, as a single shepherd can control a large flock
- The source says
This flocking instinct contributes to their economic significance as a single shepherd can control a large flock of animals
Note: 'part of their value to farmers' is 'contributes to their economic significance' - The page saysSeparate a sheep from the others and it becomes considerably stressed, often calling out and pawing at the ground

- The page saystags: agricultural
- The source says
In general, sheep feed mainly on grasses while in pastures and can be fed a wide variety of hays and oats
Note: task #564; replaces savanna, whose definition (tropical grassland, prolonged dry seasons, migrating herbivore herds) fits nothing in the sources. The breed is an English farm animal at pasture; USSA has its Norfolk Horn ancestors in "The upland regions of Suffolk, Norfolk and Cambridge". ADW's "mainly" is the diet's emphasis, not a hedge on the pasture. - The page saystags: social

Note: task #564; replaces social-colony, which asks for a strict division of labor.

ADW also: "Sheep become considerably stressed when separated from others". - The page saysA hypnotic, endlessly looping groove that pulls a whole crowd along with it, for a sheep whose flocks, up to 1,000 or more, move over an area as a group rather than as individuals, with no leader starting the grazing

The human brain has evolved specialized neural mechanisms for visual recognition of faces ... Sheep also recognize and are attracted to individual sheep and humans by their faces, as they possess similar specialized neural systems in the temporal and frontal lobes for assisting in this important social task, including a greater involvement of the right brain hemisphere

- The source says

How the table was made: a writer drafted the profile from these sources and logged each claim with its quote, a reviewer with nothing but this table checked every sentence said no more than its quote, and a script confirmed each quote appears word for word in the source. The method is in the site'sAbout page.
