Bobbers
The most widespread breeding sandpiper in North America, the spotted sandpiper is identifiable via their jerky, teetering walk where they constantly bob their tail up and down. Skittish, small, and fast, these birds race across muddy banks looking for insects and small invertebrates to snack on. On campus, there is a mating pair that has raised brood on Kingswood Lake’s main island for the past 2 years. The species is also facing a steep population decline currently, as are many sandpiper species in the US, due to habitat loss and pollution.
Swapped Mating Roles
While most sex relations in birds consist of the females nesting and taking care of the brood and the males dealing with territorial defense, the roles are swapped for spotted sandpipers. Females' testosterone levels will increase seven times their usual level during mating season, where they will chase competitors off their territory and search for food. Meanwhile, males will incubate eggs and take care of the nest.
