Invading Birds!

The video discusses the concept of invasive species, using starlings in North America as a primary example. Initially absent from the US, starlings were introduced from England and became invasive, outcompeting native birds for resources. The video also highlights accidental invasions, such as the brown tree snake in Guam, and suggests prevention methods like monitoring and careful relocation of species.
