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. Its documented range includes the United States as its primary stronghold, with additional records from Belgium, Denmark, Norway, and the United Kingdom, where individuals may appear as vagrants or established non-native populations. Common grackle is typically associated with open and semi-open habitats including agricultural fields, marshes, parks, and suburban areas.
