I can't really imagine anyone taking swamphens there
deliberately, less so accidentally.
For what it is worth, swamphens got accidentally introduced in
south Florida in the USA in the 1990s. As I remember the story,
someone was keeping several of them and along came a hurricane
that let them go. They've been multiplying and spreading. State
game wardens spent 2-1/2 years trying to eradicate them, killing
about 3,200 of them. They recently gave up. They estimate that
the current population is 2,000-3,000 birds. So evidently, it
doesn't take much of an introduction to get a good population of
them going.
