Like the Eurasian Sparrow, and the Rock Pigeon, the European Starling is a well established introduced species whose range spans over the entire U.S. Although the Starling can be a very pretty bird when it dons its iridescent mating plumage, they nonetheless have a negative impact on other cavity-nesting birds as their aggressiveness and large numbers tend to monopolize nesting places from more fragile species such as the Purple Martin.
Watching massive flocks of Starlings move above city-scapes in the evening, apparently with some sort of common consciousness (no not really) is a truly incredible sight.
