That stems from a remark in The Royal Natural History by Richard Lydekker in 1894, which simply says "it is also found across the straits of Gibraltar and some of the neighboring parts of Spain". Given that the macaques were frequently kept as pets and moved around, if they were found wild in Spain at this time there really isn't anything to say whether they were "original" or introduced.
The Arnhem chimp colony is at Arnhem zoo, not Apenheul. Its a typical zoo colony but one of the earliest to include a large number including several males and living in a large naturalised enclosure. To my knowledge Apenheul have never(?) held Common Chimpanzee, only Bonobos.
I googled the reference. It doesn't appear to be online (it is a chapter in a book rather than a journal paper), but it is "van Hooff, Jaram. A structural analysis of the social behaviour of a semi-captive group of chimpanzees. In: von Cranach M, Vine I, editors. Expressive movement and non-verbal communication. London: Academic Press; 1973. pp. 75–162."
The Black-shouldered Lapwing colonised New Zealand under its own power, but it became so widely disliked here to the point that it is no longer protected, and many people claim that it is an introduced species. Including people who love all other native species and pretend to be New Zealand bird aficionados.
Noise, harassing other native species, etc.
"Spur-winged plover" was their "old" name in Australia up to I guess the early 1980's when a number of potentially confusing and incorrect common names were "tidied up". Their spurs were the reason that as a child I would wander around on my holidays at Phillip Island with a stick over my shoulder to ward off this potentially dangerous bird. While their swooping was unnerving I never met anybody who was actually hit by one of them.
