There are a few exceptions, but I have not seen a natural Minnesota bird in my backyard for nearly a year. The House sparrow, a territorial and invasive species, has taken up residence in nearby private homes and commercial buildings and are propagating unabated.
The property adjoining mine has 14 House sparrow nests built on porches and inside the roofs. These nests will introduce 300 House sparrows to the population by the summer’s end. If you take a stroll through the neighborhood, the House sparrow is predominant and pervasive.
