I agree it might apply to many kinds of fish, reptiles, and birds.My understanding is that nonnative species would fall under the "wild" category which would apply to many fish (some of which no longer exist in nature sue to loss of habitat), reptiles, and birds.
But the title of this thread referenced CHICKEN and QUAIL keeping.
Those should exempt twice over:
Not wild, so not prohibited.(1)...Importation into the United States of any species of wild mammals, wild birds... is prohibited, unless—
Because chickens and quail WERE transported between the States in a lot more than "minimal quantities" in the year before this was enacted, they are exempt this way too....prohibited, unless—
...during the 1-year period preceding the date of enactment of the Lacey Act Amendments of 2021, the species was, in more than minimal quantities—
...transported between the States, any territory of the United States, the District of Columbia, the Commonwealth of Puerto Rico, or any possession of the United States...
(Note: Coturnix quail are domesticated, and regularly transported. Some other quail are native to the United States. I do not know enough about kinds of quail to be sure whether there are any kinds that are wild but native to somewhere else-- if there are, they would be affected, unless they are already imported or transported in sufficient quantities.)
