The introduced fish species would not become an invasive species if the fish shares a niche with the native species.

apex suck so bad...
There is a predator for this ant species.

If there is a new environment, it will likely attract species used to that environment. Maybe species not yet seen. If you don't count that as a new species then consider this, the new animals and species attracted to the new environment and landscapes might have a chance of breeding with other animals and species, creating a new species.
You give no choices to choose from. One thing could be that they find that the other organisms like themselves have not adapted well. They could then take over. They would be better at their job in the ecosystem.

An "invasive species" is defined as a species that is 1) non-native (or alien) to the ecosystem under consideration and 2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health.
Invasive species to an ecosystem results in an increase in biodiversity.

Peafowl can be pretty hardy, but like most birds from the more tropical climates, you'd be hard pressed to find them wandering around in the Midwest or far northeast where the temperatures drop below 0*F in the winter. And they also can't handle extreme heat either, but if you live in a climate where they can survive, that's a little more difficult to answer. The proper definition of invasive species as defined in the Executive Summary of the National Invasive Species Management Plan (NISMP); the term invasive species is further clarified and defined as "a species that is non-native to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health." They are considered a type of pheasant, however, where we have pheasants, they are not eliminating the populations. They are also not eliminating the native populations of their prey. Peafowl are omnivores and eat not just seed, flowers and other parts of the plant, but they also prey on snakes. Here in the US some people claim that they are invasive because in FL peafowl have caused quite a disturbance to suburban sprawl, however, Florida is suffering a larger problem of true invasive species like; the Burmese python, the Nile monitor, island apple snail and the Asiatic clam. The main difference between a non-native species inhabiting an area and an invasive species, is that an invasive species disrupts and destroys the natural ecosystem. Many times the problem is that these invasive species will eat native animals, but there are no predators to eat the invasive creature. There are plenty of predatory species out there who would love to chomp down on those brightly colored birds.
We're not 100% sure that they are. A non-native is not necessarily an invasive. Invasives are those species that, once introduced to a new range, outcompete their native counterparts and other species by modifying habitat or over-utilizing food resources. We see it with snakeheads, pythons, etc in the U.S. Mexican gray squirrels are known to occur in Florida but haven't expanded their range since introduction. There may be unknown pockets of them around, but if they were truly invasive they would likely be more common then they currently are and would no doubt drum up some concern in the scientific community.
If there is a new environment, it will likely attract species used to that environment. Maybe species not yet seen. If you don't count that as a new species then consider this, the new animals and species attracted to the new environment and landscapes might have a chance of breeding with other animals and species, creating a new species.
As a general rule, kangaroos do not inhabit the arid and semi-arid areas of Australia when there are grasslands or bushland still available. However, cactus can grow in any area, and the introduced species Prickly Pear is a particularly invasive species that is likely to be found wherever there are kangaroos.
they make the species more likely to survive.(apex)
idk
well, a virus would likely wipe out more than just the one bird species that you want to get rid of. chemicals would have an adverse effect on the environment. a competing species would either go to the surrounding areas or would take the position of the other invasive species after killing them off. i would say that it would be best to relocate the birds 50 miles away or more to be sure that they don't come back.

Invasive species is a phrase with several definitions. The first definition expresses the phrase in terms of non-indigenous species (e.g. plants or animals) that adversely affect the habitats they invade economically, environmentally or ecologically. It has been used in this sense by government organizations[1][2] as well as conservation groups such as the IUCN.[3] The second definition broadens the boundaries to include both native and non-native species that heavily colonize a particular habitat.[3] The third definition is an expansion of the first and defines an invasive species as a widespread non-indigenous species.[3] This last definition is arguably too broad as not all non-indigenous species necessarily have an adverse effect on their adopted environment. An example of this broader use would include the claim that the common goldfish (Carassius auratus) is invasive. True, it is common outside of its range globally but it almost never appears in harmful densities.[3]An invasive species is defined legally in the USA as â??An alien species whose introduction does or is likely to cause economic or environmental harm or harm to human healthâ?¦â??Alien speciesâ?? means, with respect to a particular ecosystem, any speciesâ?¦that is not native to that ecosystem."
