The source saysOne is dark grayish-black, and the other is reddish in color.
The page saysboth can turn up in the same litter
The source saysit has been determined that the two color morphs do mate, and litters are observed containing both
The page saysEarly naturalists mistook the two morphs for separate species, naming the dark one "eyra" and the reddish one "jaguarundi."

The source saysThe species that most resembles jaguarundis is Prionailurus planiceps, commonly referred to as flat-headed cats. However, jaguarundis can be easily distinguished from this other species, and are slightly longer and heavier.

The page saysfrom northern Mexico through Central and South America
The source saysJaguarundis are found in northern Mexico and central and south America.
The page saysextinct in Texas
The source saysJaguarundis are extinct in Texas.
The page saysJaguarundis weigh about 3.6 to 7.3 kilograms (8 to 16 pounds)
The source saysweighing 8 - 16 poundsNote: 3.6 to 7.3 kg converted from 8 to 16 lb. TPWD's current page wins over ADW's 2004 4.5 to 9.0 kg (Check the date).
The page saysIn captivity a jaguarundi can live 16 to 22 years.
The source saysThey live 16 to 22 years in captivity.
The page saysToday it is found from northern Mexico through Central and South America
The source saysJaguarundis are found in northern Mexico and central and south America.
The page saysIt once lived in Texas too.
The source saysJaguarundis still exist in Mexico, but are extinct in Texas.
The page saysJaguarundis hunt mostly on the ground but climb trees easily
The source saysAlthough Jaguarundis hunt mostly on the ground, they also climb trees easily

The source saysHistorical accounts from Mexico suggest that Jaguarundis are also good swimmers and enter the water freely.
The page saysIn the United States the jaguarundi has been listed as Endangered since 1976
The source saysU.S. Status Endangered, Listed 6/14/1976Note: TPWD's current page gives U.S. status Endangered with the 1976 listing date and no change since, so 'since' follows the page
The page saysTexas Parks and Wildlife now counts it as extinct in Texas

The page saysactive by day
The source saysJaguarundis exhibited a completely diurnal pattern across all sites
The page sayswhile the margay works nights
The source saysmargays were strictly nocturnal (~70% of activity between 18:00h and 06:00h)
The page saysa daytime schedule out of step with the nocturnal margay
The source saysJaguarundis and margays could only be compared across two sites, but showed the lowest activity overlap (mean Δ = 0.20), due to their nearly opposite temporal activity
The page saysCamera traps at protected forest sites across the Neotropics
The source sayswe combine data from long-term camera trap monitoring at eight protected forest sites across the Neotropics
The page saysjaguarundis keep a completely diurnal schedule, with bimodal activity peaks around dawn and dusk
The source saysJaguarundis exhibited a completely diurnal pattern across all sites with a bimodal activity peaks around dawn and dusk
The page sayswhile the similarly sized margay is strictly nocturnal
The source saysmargays were strictly nocturnal (~70% of activity between 18:00h and 06:00h)
The page saysOn an overlap scale running from 0 (none) to 1 (total)
The source sayswe used the overlap coefficient (Δ), which varies from 0 (no overlap) to 1 (total overlap)Note: 'none' and 'total' are the paper's own 'no overlap' and 'total overlap'
The page saysjaguarundis and ocelots averaged 0.39, low at every site
The source sayspairwise activity overlap in ocelot-jaguarundi were low for all sites (average of Δ = 0.39)
The page saysjaguarundis and margays, compared at two sites, showed the lowest overlap, at 0.20
The source saysJaguarundis and margays could only be compared across two sites, but showed the lowest activity overlap (mean Δ = 0.20)
The page saysThe researchers note this fits an earlier Atlantic Forest study suggesting that jaguarundis reduce competition with the larger ocelot and the similarly sized margay by being active at opposite times
The source saysThis is consistent with a study in the Brazilian Atlantic Forest [ 6 ], which suggested that jaguarundis reduce interference competition with the larger ocelots, and avoid competition with similarly-sized margays, by selecting opposite time-periods for their activities.

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.
