The Mighty New York Sparrow

The ubiquitous House Sparrow (passer domesticus) does not share in the contempt which New Yorkers have towards city birds, especially starlings and pigeons. Maybe it’s because they’re small and attractive, but we tend to look fondly upon these tiny creatures. They seem so frail and vulnerable. Ecology and history tell us otherwise. 

Like the much-despised pigeon and starling, the urban sparrow is a European transplant, brought to the New World in the 19^th century as a means of controlling insects. And since sparrow chicks consume an enormous amount of insect larvae, they did help. But the Big Apple was such a hospitable environment that their number exploded. Passer domesticus, it appears, is ideally suited to urban life. Besides insects it also consumes seeds, both of which are in abundant supply, and it will build its nests just about anywhere. As for its small size and tendency to shy away from humans, don’t let that fool you; the house sparrow is aggressive and will often take on other birds when competing for nesting space.
