The Eurasian tree sparrow (Passer montanus), also known as the European sparrow or the German sparrow, is in the sparrow family. Whilst they can fly in flocks with other species of sparrow, they can be best spotted by their chestnut-colored feathers.
Interestingly, these birds did not spread to North America on their own. In 1870, 12 of these birds were brought from Germany and released in Missouri. Since then they have reproduced and their population has spread to other areas in North America around Missouri, including southeastern Iowa and Illinois.
Thankfully, these amazing birds are not an endangered population. If you want to try your luck at spotting them, you can learn more with this article. You can even learn to prepare a nest for them so you can watch them from the comfort of your own garden and encourage their breeding.
