What adaptations make the house sparrow invasive?

House sparrows possess several adaptations that contribute to their invasive success. They are highly social birds that thrive in urban and suburban environments, allowing them to exploit human resources such as food and nesting sites. Their ability to breed year-round, high reproductive rates, and adaptability to various diets enable them to quickly establish populations in new areas. Additionally, their aggressive behavior towards other bird species helps them dominate available habitats.
