While this ubiquity can make them a nuisance around nest boxes, it can also make them a really good study subject for learning about widespread problems like environmental toxins. The Sparrow Swap Project invites you to collaborate in citizen-science research with a two-fold mission: (1) find out if House Sparrow eggs can be used to map exposure to environmental contaminants, and (2) test whether swapping real eggs for wooden eggs can reduce sparrow disruptions to other nests.
All you need to participate is a nest box that is currently attracting House Sparrows. You can participate in one of two ways:
