Common Grackle

<em>Quiscalus quiscula</em>, commonly known as the common grackle, is a passerine bird belonging to the genus Quiscalus within the family Icteridae. This adaptable species occupies various aerial, terrestrial, and aquatic environments, reflecting a broad ecological tolerance that has allowed it to thrive across a range of landscapes.
