I found out recently about Black-throated Magpie-Jays in California.
Interesting/Little Known introduced populations

- Start date
Not if they keep getting poached!
Looking at Ebird reports, it does look like the Chestnut-fronts are nearly gone. Blue & Yellow seem to be doing ok.
Yes, though I guess they move back and forth across the border. No field guide mentions them, oddly enough.
I think that the Black-throated Magpie-jay was included in the second edition of the Sibley Guide to Birds (2014). For some reason, that guide doesn't include the much better-known Pin-tailed Whydah.
Interesting. I'm more familiar with Nat Geo's excellent ones and the Peterson guides.
I have now checked, and can confirm that the second edition of the Sibley Guide to Birds does indeed include the Black-throated Magpie-jay.
The guide also includes several escapee bird species that have zero eBird reports from North America. Examples are the Java Sparrow, Sulphur-crested Cockatoo, and Lesser Flamingo. Obviously, eBird can't document every single bird sighting in existence. Still, those species are probably so rarely seen as escapees in North America that their inclusion in a field guide for the region can hardly be justified.
Which reminds me; there's also an old field guide to British birds that includes the Paradise Shelduck and Sarus Crane as escapees, and both of them are illustrated.

I would think black leopard much more likely. Its not I don't believe you , but I would like to see the photos you mentioned
Sibley is the best North American field guide, IMO. It is especially nice because it includes species not on the ABA checklist.
Here's one I hadn't heard of before - a feral population of llamas has existed in Southern Italy since at least the mid-late 1990s.
The population was established through the unsafe management of a small zoological park (the Zoological Garden of Cavriglia) that closed in 2016. The animals were maintained partly outside their enclosure and used to roam into the local woods during the daytime. Other animals that were seen outside of enclosures that failed to establish included hog deer and Japanese macaques.
A recent scientific paper about the establishment of the llamas is included below:
https://www.sciencedirect.com/science/article/pii/S1617138118302693
The paper also mentions Patagonian mara as an introduced species in Europe, but the source linked to it is just a general species profile with no information about their presence in Europe. Does anyone know more about this?

I've seen them.
Does anyone here know whether or not any feral guinea pig populations currently exist anywhere? I know that New Zealand and Hawaii used to have them.
I agree that is a shortcoming of many of them. Although in many cases I imagine it's difficult to judge whether an escaped species is established enough or gets out often enough to be worth including.
The biggest problem with North American field guides (all of them) is a lack of info on escaped domestic waterfowl. Sibley has more info on this than any other field guide, and still only devotes half a page to domestic Anser species.
I think part of the problem there is how many domestic color forms/ physical forms there are. Trying to add all of them would take a large section! Let alone hybrids...
No different than a page on Feral Pigeons! I think one could easily cover the domestic Anser species in three pages: one showing variations of A. a. domesticus, one showing variations of A. c. domesticus, and one showing variations of hybrids. Domestic Ducks (Mallard and Muscovy) could be lumped into pages showing the wild form, as well.
Are we including the Swan Goose as a domestic? Having seen domestic-type and wild type, I would say large difference. Also what about Mandarin Duck?
The wild type is rare enough in captivity that it is probably not worth putting in the field guide. Mandarin should be in field guides, IMO (I know Natural geographic and Sibley both cover it).
