The European Starling has some beautiful iridescent feathers, incredible vocalizations and is famous for their flocks forming murmurations…however they are a formidable non-native species which competes with native cavity nesters and can be a agricultural pest in their huge numbers.The Brown-Headed Cowbird commonly chums around with Starling flocks and has adapted well to the human landscape. They don’t make their own nests but rather drop eggs off in other bird nests and leaves them to be raised by an unwitting foster parent.
