Rusty Blackbird

rusty left 1I made another trip to see the Rusty Blackbird that has been hanging out behind the Hillsboro Public Library for the past month. This species nests in boreal wetlands across Alaska, Canada, and the northeastern states. They typically winter in the southeastern U.S., so they are extremely rare in Oregon.

Unfortunately, they are becoming extremely rare in their normal range, as well. Since the 1960s, the population of Rusty Blackbirds has declined by between 85 and 95 percent. Probable causes include the drying of boreal wetlands due to climate change, mercury contamination, changes in breeding habitat caused by logging and farming, changes to bottomland forests in the birds’ winter range, and poisoning of “nuisance” blackbird flocks. Information on the situation can be found here and here.
