    I think this may be a misunderstanding. The Ringtail is a native small carnivore related to racoons which is fairly widespread in Texas

    They are very common on ranches in Texas. Some of the ranches may practice limited husbandry beyond some feeding, but I do not think there are any free-roaming Scimitar-Horned Oryx populations in the state. They may exist on the Mason Mountain WMA which is public land, but even there they would be behind high fences and their movements limited...a situation not that uncommon I guess with other species and populations considered “wild” nowadays.

    This sort of post is where you need to provide evidence for a claim. Free-ranging captive animals do not count as an introduced population.

    He says they might me. What really convinced me is that thatkazakhbirder seemed to know more about it. I've messaged him for more info.

    He said that a director at Houston Museum of Natural Science told him this population is wild.

    On another site he uploaded the photos to he specifically said he was told by the local rancher that the lemurs come from a local place from which they "run loose during the day and they always return home at night" - A odd Texas sighting

    On your link, the comment by thatkazakhbirder gives no information so I'm not sure why that would "really convince" anybody. If the species actually was "considered introduced in Texas" then that would be a very easy thing to verify because it would be an official position.


    Based on what?

    I've just seen this field guide to the nonindigenous marine fishes recorded off the coast of Florida. It includes the records of forty different exotic fish that have been observed, ranging from single sightings (such as the brownbanded bambooshark and masked pufferfish) to completely established species such as the lionfish.

    The document is included below:

    Either way, there are/were some wild primates in Texas:



    EDIT: Turns out "were" is the right word.

    If you mean the population on Vancouver Island, it's been well known and documented for years.

    Gemsbok I know is becoming established in NM (along with Aoudad and ibex), but zebras establishing a wild population in CA I find suspect.

    I suspect he's talking about the herd on the Hearst Ranch, which are "wild" in that they are not managed but they are not actually a wild population.

    This article explains the situation: Is That a Herd of Zebras Over There?

    Fair enough, though I agree not truly wild.
